The emulsifying machine is to shear, disperse and impact the material through the high-speed rotation of the homogenizer head connected to the engine. In this way, the material will become more delicate, and the oil and water will be melted. It is widely used in cosmetics, shower gels, sunscreens, and many other cream products that use emulsifying machines. Sauce, juice, etc. in the food industry. Ointments in the pharmaceutical industry. Emulsifiers are used in petrochemicals, paints and inks, etc.






Before using the emulsifying machine, you must have a certain understanding of the characteristics, maintenance and repair of the emulsifying machine. Using the emulsifying machine in the right way can not only prolong the life of the emulsifying machine, but also will not cause unnecessary waste.






It requires precise cooperation between the rotor and the stator, and the claw structure of the working head can absorb materials in both directions, and the shearing efficiency is high. Intermittent high shear dispersing emulsification homogenizer is through the high-speed and stable rotation of the rotor to form high-frequency, strong circumferential tangential velocity, angular velocity and other comprehensive kinetic energy efficiency. Under the action of the stator, strong and reciprocating hydraulic shearing, friction, centrifugal extrusion, liquid collision and other comprehensive effects are formed in the reasonably narrow gap between the stator and the rotor, and the materials circulate and reciprocate in the container. It is stable in operation, low in noise, convenient in cleaning, flexible in maneuverability, can be used continuously, and can superfinely disperse and emulsify materials. It can be widely used in emulsification, homogenization and dispersion in industrial production.






There is a machine pretty similar to emulsifying machine, which is called homogenizer machine. Homogenizers are mainly used for tissue dispersion in the biotechnology field, sample preparation in the pharmaceutical field, enzyme treatment in the food industry, detection of pesticide residues in food and veterinary drug residues, as well as in the pharmaceutical industry, cosmetic industry, paint industry, and petrochemical industries. The homogenizer adopts a stainless steel system, which can effectively separate the surface of the body sample and the homogeneous sample of microorganisms contained in it. The sample is packed in a disposable sterile homogenizing bag without contact with the instrument, which meets the requirements of rapidity, accurate results and repeatability. good request. It can be widely used in emulsification, homogenization and dispersion in industrial production.






Compared with centrifugal dispersing and emulsification equipment (such as colloid mill, high shear mixing emulsifier, etc.), the characteristics of the homogenizer are:






1) The refinement effect is stronger. This is because the valve core and the valve seat of the working valve are in close contact at the initial position, but a slit is forced out by the liquid during operation; while the rotating stator of the centrifugal emulsification equipment is in order to meet the requirements of high speed Rotating without generating too much heat, there must be a large gap (relative to the homogenizing valve); at the same time, since the transmission mechanism of the homogenizer is a positive displacement reciprocating pump, theoretically, the homogenizing pressure can be infinite The higher the pressure, the better the refinement effect.


2) The refining function of the homogenizer mainly utilizes the interaction between the materials, so the calorific value of the material is small, so the performance of the material can be kept basically unchanged.


3) The homogenizer can transport materials quantitatively, because it relies on reciprocating pump for feeding.


4) The homogenizer consumes a lot of energy.


5) The homogenizer has more wear and tear, and the maintenance workload is large, especially in the case of high pressure.


6) The homogenizer is not suitable for high viscosity.






Besides these two machines, Filling Machine is also used together when producting. And the storage tank and mixing tank cooperated with conveyor belt are also indispensible.

Blow molding is a process that can be used to produce a wide array of plastic products that can be small, large, or even custom-shaped. Besides bottles, jerry cans, and drums, plastic floats are also a very popular application for this kind of process. Float blow molding machines are accumulator type, and they can produce floats that are later on used for different purposes. 3 types of plastic float moulds commonly produced by float blow molding machines include the following:


- Plastic solar floats for PV systems


- Plastic floats for docks


- Plastic floats for aquaculture fish farming






1. Blow molding of plastic floats for PV systems


A common application made by float blow molding machines is HDPE floats for photovoltaic (PV) systems. These systems are power generation systems that consist of PV modules mounted on water surfaces by using plastic floating platforms that are lightweight, cost-effective, and which may also vary in size and shape in order to fit the requirements of the manufacturer.


In the case of PV systems, several solar floats are combined to form a giant pontoon. These solar floats are usually made of HDPE, a plastic that is known due to its tensile strength, UV, and corrosion resistance.






2. Blow molding of plastic floats for floating docks


Floating docks are incredibly useful because they are adaptable, durable, and easy to maintain compared to other docking types. This kind of dock floats on top of the water instead of being attached to the surface beneath it, meaning that as the water moves and levels fluctuate, so does it. These structures are commonly made of polyethylene, so they will not warp, rust, or dent, and can withstand severe weather conditions with the right anchoring hardware. Another benefit of plastic floats made with polyethylene is that this material allows docks to stay cool and burn-free even during hot summers. Moreover, by manufacturing floats with a textured surface which makes them slip-resistant and easy to maintain a grip, they become an incredibly safe option for everyone.



Float blow molding can produce plastic floats that vary in size and shape and can also be customized to create unique layouts. The resulting plastic floating docks are made for residential, commercial, or industrial purposes and are often preferred because they can be relocated, altered, or even extended. Moreover, they are safe and stable for anyone walking or making use of them.






3. Blow molding of plastic floats for aquaculture fish farming


Another very popular application of blow molding for large products is the molding of Paddle Wheel Aerator Floats and Gear Box Covers for aquaculture. These floats are used in fish farming for giving the fish the oxygen they need from the environment for breathing. With a paddlewheel aerator, water currents are created, which is an environment that attracts fish and shrimps.







With float blow molding method, many moulds can reach a better performance such as chemical barrel mould, road safety mould, auto parts mould, tray mould, toy mould, trash can mould, portable toilet mould, massage chair mould, bus seat blow mould, etc.

Aluminum tube appears across an extensive range of aerospace and commercial industrial applications, including healthcare products, recreation products, and machine parts. Manufacturers prize aluminum for its durability despite being only one third the weight of steel. Due to this versatile combination of strength and flexibility, many applications benefit from the effective use of aluminum tubing.






Aluminum Tubing's Properties


Because of its light weight, aluminum tubing offers a greater volume of tubing per weight purchased than steel. Many products benefit from the use of a lighter tubing material, particularly those that require a degree of mobility such as wheelchairs and outdoor furniture. Aluminum tubing also does not tarnish, and it is more receptive to paint and other decorations than other metals, enhancing its aesthetic appeal.






Aluminum conducts heat extremely well, making aluminum tubing a great candidate for applications reliant on temperature control, including refrigerators, solar power, and air conditioning systems. Additionally, applications such as hydraulic systems, fuel lines, frames, and racks benefit from aluminum tubing's lightweight and durability.






Aluminum comes in several different alloys. Aluminum forms strong alloys with a variety of different combinations of magnesium and silicon. In particular, manufacturers use the aluminum square tube alloy 6061 for many medium- to high-strength applications because of its increased weldability and exceptional corrosion resistance. The 6061 aluminum square tube also anodizes easily, and its properties render it great for heat treating. It's also the least expensive aluminum tube alloy available.






Manufacturers also use aluminum square tube alloy 6063 for its extremely smooth surface finish. Because it possesses only about half the strength of aluminum alloy 6061, aluminum alloy 6063 often appears in applications that value aesthetics over strength. This material still possesses many of the same anodizing capabilities as aluminum alloy 6061.






When to Use Aluminum Tubing


Aluminum tubing benefits a wide variety of industries. Outdoor recreation manufacturers use tubing to construct materials like tent poles, camp chair frames, and outdoor tables. In the medical industry, aluminum tubing appears in wheelchair frames, collapsible stretchers, bed frames, and crutches. Aerospace, automobile, and rail transporation manufacturers make use of aluminum tubing in fuselage, hydraulic systems, and fuel lines, and its heat-conductive capabilities render it a good alternative to steel or other heavier metals in refrigerators, engines, and HVAC systems. Aluminum tubing can also be found supporting chain-link fences, lining tables, and housing electric equipment such as desktop monitors.






For its outstanding characteristics, aluminum profile can be made into many different shapes except for tubes like aluminum bar, aluminum sheet, aluminum strip coil, aluminum checker plate, aluminum round tube, aluminum square tube, aluminum rectangular tub, aluminum oval tube, etc.

Precision investment casting, also known as the lost wax casting process, is an ancient metal forming technology. The technique is several thousand years old, originally producing ornaments and jewelry. Today, many high tech components are fabricated to tight tolerances using this technology.






Colloidal silica is used as an investment casting binder with refractory grains such as alumina, aluminosilicates, fused silica and zircon. These systems are used for the casting of many types of metals. NexSil 8, an eight nm alkaline sol, is a preferred binder for these systems.






In this type of casting, mould is prepared around an expandable pattern, and a single gating system is used to make a large number of casting. The pattern used to make mold is get destroyed or it completely lost its shape during investment casting. The common pattern material for precision investment casting wax, so this process is also known as lost-wax casting. The other important pattern materials used in investment casting are plastic, wood, and mercury. When mercury is used to make a pattern then the process is known as mercast.






The various steps included in investment casting


Making of pattern



The first phase of investment casting is the preparation of pattern. The individual pattern is made for each and every casting is to be made. The pattern material is wax; molten wax is injected under high pressure into the metallic die. The wax is then allowed to solidify to produce the pattern. This pattern is then ejected from die, and attached to the gating system.






Making of mould


The cluster of patterns attached to the gating system is then dipped into a slurry, made of refractory /ceramic coating material. The excess slurry is allowed to drain off from the pattern. A coating of material will formed as slurry drying. A thin shell is formed around the pattern. After curing of shell, the pattern is again dipped into slurry. The process repeats to increase the thickness of shell gradually. The required shell thickness depends on the size and shape of casting and properties of ceramic material used.






Removal of pattern from mould (Burnout)


The next step is the removal of pattern from the casting. It can be achieved by heating of mould. The wax pattern is meltdown, and it is completely drained through sprue by inverting the mould. The hot vapor of solvent such as trichloroethylene is used to remove remaining waxy residue in the mould cavity. The wax that flows down can be reused to make another pattern.






Preparing of mould and casting (Preheating, Pouring)


The mould is then preheated certain temperature (depends on the complexity of casting and material of casting and moulding). This reduces the last trace of wax and ensures proper filling of thin sections of mold, which is very difficult to achieve in cold mould. The molten metal is then poured into the mould cavity, sometimes slight pressure is preferable. After solidification, the casting takes out of the ceramic shell by breaking it or chemically dissolving it.






Applications of investment casting


This method of casting is used where high precision is required. It cannot use to make heavy casting. Investment casting largely relied on making of very intrinsic shape that cannot cast by another method. The common application includes jewelry, surgical equipment, vanes and blades for gas turbine, bolts and triggers for firearms, impeller, and stainless steel valve bodies. With this method, you can get various of pump part, valve part, auto part casting, handrail fitting, stainless steel glass clamp, stainless steel handrail elbow, stainless steel handrail bracket, stainless steel handrail support, marine hardware, etc.

What is a metering pump?


A metering pump is used to add small but accurate volumes of a liquid to other fluid streams or vessels. Metering pumps are also called dosing pumps and proportioning pumps. A metering pump must be able to deliver liquid with an accuracy of greater than 3% across a wide range of discharge pressures.






What applications use metering pumps?


Maintaining a constant flow rate regardless of differential pressure or fluid viscosity.


Delivering a variable flow to maintain a system parameter (for example, pH).


Injecting a discrete dose (typically required in batch processing).


Metering is required in many industries, including pharmaceuticals, water and waste treatment, food and beverage production, power generation, chemical processing, petrochemicals and oil and gas extraction. Liquids can be anything from fragrances and pigments in the production of toiletries or food or acids and alkaline solutions for chemical processes and water treatment.






What type of pumps are used for metering?


With applications delivering low viscosity liquids at high flow rates (>1 m3/h) and low delivery pressures it is possible to use a centrifugal pump to achieve a controllable flow. This can be the most cost-effective solution. However, in other situations, accurate metering necessitates the use of a positive displacement pump. This class of pump moves a fluid by repeatedly enclosing a fixed volume, with the aid of seals or valves, moving it mechanically through the system. The pumping action is cyclic and by controlling the motor’s speed or stroke length, a specific delivery rate or accurate single dose is possible.






There are many types of metering pumps for different usages such as plunger-type metering pump, hydraulic diaphragm metering pump and mechanical diaphragm metering pump. Besides, reciprocating pump is a widely used pump as well.






Reciprocating Pump is a Positive Displacement type pump that works on the principle of movement of the piston in forwarding and backward directions whereas the Centrifugal pump uses the kinetic energy of the impeller to supply the liquid from one place to another place. It is a machine that converts mechanical energy into hydraulic energy. Reciprocating pumps are in use where a certain quantity of fluid (mostly sump) has to be transported from the lowest region to the highest region by the application of pressure.






The reciprocating pump uses when a relatively small quantity of the fluid is transported under high pressure. This type of pump is more appropriate for small flow rates at high pressure as compared to centrifugal pumps. A certain amount of liquid (mainly sump) must be applied and transported from the lowest to the highest area when using a plunger or piston pump. For example, if you go to the bike water servicing, you can check that the water used for servicing is gathered from the sump and sprayed onto the bike by providing pressure through the nozzle.






Reciprocating Pump Working Principle


The reciprocating pump works on the principle of positive displacement. A reciprocating piston pump consists of a piston that moves back and forth in a cylinder. The piston is connected with a crankshaft with the help of a connecting rod. This piston moves as the connecting rod move due to the motion of the crankshaft. The crankshaft connects with a motor that rotates it.






The pump cylinder is connected to a suction pipe and a discharge pipe with a suction valve and a delivery valve. The inlet and outlet valves act as check valves that allow the fluid flow to flow in one direction. The fluid sucks into the cylinder through the inlet valve. The fluid exits the cylinder of the pump through the outlet valve. With different application, it can be devided into many types like High-pressure reciprocating pump, triplex plunger reciprocating pump, etc.






There are many other pumps used as chemical dosing package, such as pneumatic diaphragm pump, pneumatic diaphragm pump with supercritical extraction system and so on.

The early childhood education (ECE) scene has rapidly evolved over the last decade. Increasing studies have affirmed and documented the importance of learning and development of children in the first 6 years of life, making early education an increasingly important component of a successful educational, social and family policy agenda. The need to raise the quality of preschool programmes through better teacher training have also been highlighted in recent government initiatives.

Paper Bag is a type of contemporary bag that is booming. Not a type of fashion bag, but a versatile bag replacement from a plastic bag. Many models are accompanied by varied colors. Even more interesting from time to time, as evidence of the development of producer creativity. In general, the function of Paper Bag is the same as the function of a plastic bag.






Paper Bag is a simple bag made from paper. The paper used can be thick paper, namely hard cover paper, manila paper, rainbow paper, calendar paper, paperboard and other types of paper. The corrugated box is the most widely used one. The important thing is the paper is thick and not easily torn. For this reason the function of Paper Bag is much loved. It is simple and modern when taken rather than using a plastic bag.






The appearance of the Paper Bag clearly provides a practical function that is inevitable. We become easier to carry luggage, without fear of damage or fear of breaking down. Stronger and a lot more in size.






For Paper Bag, a small form is usually used for small items, namely packages of cosmetics, accessories, snacks, and / or for souvenirs for weddings. Whereas for large-sized Paper Bag used to carry books, paper, cloth, food and others. Certainly the weight of the goods carried is not large. Besides that Paper Bag is also often used to carry food. More practical and avoid the dangers of ingredients contained in plastic bags that we have been using.






Various Functions and Advantages of Paper Bag From Plastic Bags


The main appearance of the Paper Bag is to reduce the amount of plastic bag waste. You could say this is the main function of Paper Bag. Where as we know that so far we have too deified the use of plastic bags, both for putting things in the form of fashion items, food, drinks or anything else.






While we may be accustomed to seeing every bit of our food wrapped in air-tight plastic wrap, food and coffee shouldn’t be limited to only plastic. Since they were developed in 1852, paper bags continue to be a popular bagging item, despite the competition from plastic bags. While you may not be able to find them in as many stores as you once could, paper bags continue to be a popular choice for shopping and food items due to the increased durability and their eco-friendly disposition.






Paper bags have come a long way since their humble beginnings in the mid-eighteenth century, with manufacturers developing paper bags that are more resilient and durable. Their box-shaped design also allows them to stand upright and hold more goods at once. When compared with plastic bags, they are also much safer. For example, a child is not likely to suffocate from accidently putting a paper bag over their head, as they are with plastic bags.






Paper bags have become something of a fashion and status symbol in today's market, due to the amount of time and effort that brands spend designing an attractive paper bag for their wares. With attractive paper bags that advertise the company's brand, customers are providing a form of free advertising and endorsement.






Paper bags also offer many eco-friendly benefits to those who use them. They can be taken care of and continually reused. They are both recyclable and biodegradable. Paper bags are made from a renewable natural resource, can be reused repeatedly and can be shipped to a paper mill and remade into new paper. In fact, it actually requires less energy for paper bags to be recycled than it does for plastic. Paper bags are also biodegradable and pose less of a threat to the environment and wildlife.






Paper Bag and Paper Box have many different usages, for example, they can be used as gift bag or gift box, packaging boxes, jewelry box, corrugatedpaper box, cosmetic box, shopping bag, etc.

What Is A Baler?
A scrap baler machine is used for recycling applications. It is generally a hydraulic press that compacts materials into a dense package of a specific size. The compacted materials are then held together with wire, twine, or strapping.

Balers are used to compress recyclable and waste materials into small, manageable bales. Balers especially scrap metal baler machine are used in many industries such as manufacturing, schools, retail outlets, recycling facilities, and other businesses. Materials such as cardboard, textiles, foam, plastics, cans and bottles are compressed in a baler like vertical baler machine and then baled for transport to a garbage or recycling facility. Any situation where there is a need for a baler or compactor that is small, easy to operate, produces very small bales that are light weight and easy to handle. Basically these are machines that have refrigerator style doors with push button type controls that have a mix of features found on both balers and compactors.

Balers are used for the following reasons:
Reduce the volume of material handling and more efficient shipping
Savings from avoiding disposal of materials
Generate revenue from the sale of baled materials
Meet or exceed industry specifications to maximize product value
Balers minimize the amount of time spent managing materials, require less space for recycling bins, and increase the number of materials your business can recycle, therefore reducing waste disposal costs.

How Do Balers Work?
Balers have a steel frame that supports a hydraulic ram powered by an electric motor-driven pump. Hydraulic oil is then pumped under pressure to the cylinder and moves the plunger (ram) against the material that is being baled. The material is packed into a dense block (bale) in the bale chamber. Once it is made, it is tied by hand or mechanically and ejected from the baler.

Baler Vs Compactor: Which Is Right For My Business?
The main similarity between a baler and compactor is they both reduce the volume of materials through a compression process. The most significant difference between them is that they process different materials. Understanding your business’s needs and the types of materials you generate will give you an idea of what is best for you.

On the other hand, businesses use compactors that generate significant amounts of waste, and it will be transported to a landfill or processing facility. Balers are best suited for recyclable materials (cardboard, paper, plastic, and metal). Balers come in various sizes, including vertical balers, horizontal balers, and more.

For the packaging and recycling of metal, you may need other machine to work in connection with balers, such as metal briquetting machine, hydraulic shearing machine, hydraulic press brake, hydraulic guillotine shear, cable wire recycling machine, metal shavings crusher and so on.

With the advance of several methods and developments in the construction field, new construction materials and equipment are deployed to improve the excellence of work. Interlocking bricks are the improved version of the traditional bricks. They are made up of clay or cement and are slightly different in shape and structure. Interlocking bricks are manufactured in such a unique way that each brick gets locked itself with another brick using a shear key and lock mechanism. These bricks can be laid one after another without using any mortar or binding material.

Manufacture of interlocking bricks
Interlocking bricks are manufactured by blending and squeezing Sand, Soil, and Cement in a machine to enhance the strength and quality of the structure.

Design of Interlocking Bricks
In the design of the interlocking brick for container yard pavement, the structure of the shear-key will differ from one another. A lock is facilitated on the contrary side of the brick. Interlocking bricks come up with various shapes and sizes & the locking mechanism also varies and depends on the supplier.

Earthquake resistant Construction Material
The mortar is the primary means of seismic load transfer in traditional brick walls. During an earthquake, once the mortar fails to transfer the load, the complete structure gets affected and collapses. The self-locking structure of the interlocking bricks allows the seismic forces to scatter the stresses and seismic loads across the entire structure.

Do not require Plastering
Interlocking bricks are formulated with a smooth finish and texture. If you are utilizing interlocking bricks in the wall construction, there is no need of plastering the walls. Apply a thin layer of paint to give a smooth finish and elegant looks.

Low thermal mass facilitates cooler interiors
Walls constructed using interlocking bricks are less heat-intensive in nature as interlocking bricks have less thermal mass. Hence the interiors are much cooler.

Can be reused
When a building is being stripped down, interlocking bricks can be saved without destruction and reused for new construction in the future.
