Fully automatic foam molding machine is more popular in the market

Although the foam molding machine we used in the past is also very practical, it needs to be manually operated in many steps, and the overall processing time is slightly longer. However, from the perspective of modern technology and work efficiency, it is true that some cost-effective fully automatic equipment is more welcomed and recognized by the market. Many businesses have begun to switch to such a molding machine to ensure their follow-up. Use better. The popularity of such a device is also inevitable.

First, the equipment is easy to operate and ensure the parameters are correct.

Now the workers who operate the foam molding machine need to hold a certificate to work, so as to ensure that there are no problems and that they are operated in accordance with the corresponding requirements of the country. We should pay special attention to production safety. And the operation of the fully automatic equipment should be simpler. It can be said that as long as the workers who can perform the foam molding process know how to operate, the effect of the operation process can also be guaranteed. The most important thing is to ensure that the parameters are correct, and we don’t need to worry about the subsequent processing.

Second, the safety factor is higher and the equipment stability is stronger.

The manufacturers of foam molding machines have also comprehensively improved the equipment. It can be said that many equipments have corresponding inspections and can complete the corresponding operations according to our requirements. It can be said that the stability of the equipment is still very strong. Yes, there is no need to worry about using it. Such a device is stable and easy to operate, and it can ensure the follow-up self-test function. Once there is any problem, it can be completed in a short time without worrying about possible impact.


How is EPS Manufactured?

Expanded Polystyrene foam is manufactured from the by-products, or left overs, from the oil refining process.  These blocks are then cut into smaller usable sizes that vary with the application. The description below explains how the manufactures the EPS foam pieces and sheets you are familiar.

We buys raw material in the form of resin or beads of styrene. Each bead has a microscopic dot of Pentane formed into its center. This material is furnished in air tight bags. These bags keep the beads “fresh” by assuring that the Pentane within each bead can not escape into the atmosphere and render the material.

These beads of Styrene are about the size of a grain of salt and have a similar consistency. It is crucial that the beads are stored in a tightly controlled environment where the amount of Pentane within their plastic shell remains consistent. Each step of EPS production requires strict adherence very tightly controlled quality standards.

These beads of resin are loaded into a machine called a “pre-expander”. It does exactly what the name implies. Steam is injected into the beads at 212 degrees F. The heat accomplishes two things. The wall of each bead is softened and becomes flexible and the increased temperature also causes the Pentane to expand within the softened beads. The beads puff up like popcorn to 30 times their original size.

The next step is the molding process. It is at this point that the individual expanded beads are molded into a single, homogeneous block. This is the most crucial stage in the production process and it is essential that very strict quality control standards are adhered.

Once again, steam is used to deliver heat to the process. A precisely measured quantity of beads is blown into a steel mold. Steam is then injected into the pre-expanded beads to heat the mix to 212 degrees F. This heat causes the wall of each bead to soften and the remaining pentane within each bead expands. This expansion causes the beads to increase in size within the steel mold. This expansion increases the pressure and the beads are forced together to form a single block. The soft bead walls actually allow the beads to melt together into a single solid block. At this point the mold opens like a clam shell and the block of EPS foam is removed.

After the block has been removed from the mold it is carefully weighed and marked so it can be traced throughout the production process. Adherence to the proper weight assures that the correct “density” or “weight per cubic foot” is maintained. A needle is injected into the center of the block and pressurized air is applied. The degree to which the block restricts the flow of compressed air is an indication of the proper amount of fusion between the individual beads within the block.

Immediately after coming out of the mold, the surface of each block is perforated with thousands of tiny holes. The purpose of this step is to help moisture to escape the freshly molded block. The molding process leaves a smooth skin on the outside of each block and the perforator allows the moisture, a result of the steam, to more easily escape from the block.

Once the blocks have been molded, perforated, weighed, and tested for proper fusion, they are moved to the “drying room”. Within this room the temperature is maintained at approximately 140 degrees F. There are large blowers that circulate the air within this room. These steps are designed to remove as much of the moisture from the block as possible. The increased temperature also helps to reduce any internal stresses that may exist within the block as a result of the molding process.

If flat sheets are desired, a series of wires are connected to a “slicer” with the proper horizontal spacing to give the exact dimensions needed. The wires are heated with electric current and melt through the foam leaving a smooth, consistent, surface. If irregular shaped parts are required, a computerized contour cutter is used to duplicate whatever shape has been programmed into the machine’s software. A variety of cutting techniques is used to achieve the varied demands of our customers.


The Meaning And Working Principle Of The Molding Machine

The molding machine, also known as the box opener, means automatic folding, forming, and folding of the bottom folds. At present, the next part of the tape is pasted, and the cardboard board is opened. The bottom of the box is folded according to a certain procedure and is sealed with adhesive tape to send to the special equipment of the packing machine. Automatic carton forming machine and automatic opening machine are the assembly line equipment of large batch carton automatic opening, automatic folding under cover and automatic sealing bottom tape. All the machines are controlled by PLC+ display screen. It is very convenient to operate. It is an essential equipment for automatic production of scale.

The working principle of the molding machine is similar to the injector used for the injection. It is the process of the injection of the plastic (or viscous flow) plastic into the closed mold cavity with the help of the thrust of the screw (or the plunger). Injection molding is a cyclic process, each cycle mainly includes: quantitative feeding – melting plasticization – pressure injection – cooling – mold opening and taking parts. Remove the plastic parts and then close the mold for the next cycle.

EPS foam cutting machine introduction

The EPS foam cutter is a computer-controlled machine that can cut any three-dimensional product from extruded and expanded eps (polystyrene) foam. The three-dimensional model is machined by walking in the X and Y directions by means of a computer-controlled actuator (stepper motor) that drives the heating wire. This allows fast and accurate cutting of the foam. The control of the precision allows us to cut almost any shape from a material whose thickness is the same as the thickness of the desired product.

By designing and cutting multiple faces of a product, more complex three-dimensional articles can also be formed. Through the use of a turntable, generally used for profiling, it is also possible to cut out rotating bodies, including spheres. Structure of the EPS Foam Cutting Machine There are 8 micro stepper motors in each of our foam cutters: 4 X-axis, 2 Y-axis, 1 turntable, 1 side bracket, these high-quality motors Guaranteed high accuracy and longevity. EPS foam cutters are light and strong, with amazing cutting accuracy and repeatability. The heating wire/fan box is a place where the heating wire is fixed. When cutting, the micro fan is used to cool the heating wire, and at the same time, a special spring compensates for the elongation of the heating wire after it is heated.
