The role of the foam molding machine in the production process What is the use process of the foam machine? Today I want to introduce you to this aspect. I hope that through the introduction of this article, you can have a certain understanding and understanding of the use process of foam machinery. Let’s follow the experts from Hebei Changxing Foam Machinery Co., Ltd. Let’s take a look at the relevant content introduction 1. The inner template of the forming machine adopts a horizontal adjustable compression system, which can improve the adhesion, porosity, moisture content, thermal conductivity of the board, increase the flame retardancy of the board, and reduce the probability of deformation of the board. Reduce the generation of waste and reduce production costs. 2. The equipment has a built-in surface pressure sensing device, which can accurately sense the pressure between the plate and the inner mold cavity during production, thereby effectively controlling the forming time of the plate, ensuring the yield of the plate and reducing the deformation of the plate. 3. The vacuum system, air pressure, and hydraulic components all adopt well-known brand products to ensure the high-quality operation of the equipment. 4. The body of the forming machine is welded with high-quality steel. Through sandblasting and other treatments, the equipment is neatly strengthened and can withstand the expansion force and external impact of high-density plates. 5. The mold cavity adopts a stainless steel template, the steel structure has a reasonable thickness, has a strong anti-corrosion ability, and is easy to clean. The surface is polished and mirrored to facilitate demolding. 6. Adopt low-pressure and large-flow vacuum penetration molding technology to increase output. 7. The control system adopts touch screen and PLC, automatic cycle production, automatic foam detection, and the function of the foam forming machine in the production process to ensure the orderly production of real gold plates. You may want to know: A certain amount of foaming agent and water vapor are retained in the pre-expanded beads of the foam machinery and equipment. When they are out of the machine, they will condense into a liquid, and the liquid foaming agent will dissolve into the polystyrene to make bubbles The pressure in the medium drops quickly, negative pressure (partial vacuum) appears in the bubble, and the beads are soft and easily deformed. Therefore, when air is sent, try not to make the wind pressure too large. The inner wall of the duct should be as smooth as possible, and the bending radius should be as large as possible (to reduce collision resistance). The pipeline should be a good conductor of electricity, and the entire line must be grounded to avoid static electricity. Sparking, the transmission speed should not exceed 8m/s to avoid damage to the beads. A certain amount of foaming agent and water vapor are retained in the pre-expanded beads of the foam machinery and equipment. When they are discharged from the machine, they will condense into a liquid, and the liquid foaming agent will dissolve into the polystyrene to quickly reduce the pressure in the bubbles. , There is negative pressure (partial vacuum) in the bubble, and the beads are very soft and easily deformed. Therefore, when air is sent, try not to make the wind pressure too large. The inner wall of the duct should be as smooth as possible, and the bending radius should be as large as possible (to reduce collision resistance). The pipeline should be a good conductor of electricity, and the entire line must be grounded to avoid static electricity. Sparking, the transmission speed should not exceed 8m/s to avoid damage to the beads. The beads just out of the foam mechanical pre-expander are all damp. After being released from the pre-expander, they absorb air and suddenly encounter cold, causing the foaming agent in the honeycomb cells to condense and form a negative pressure in the cells, so the beads are in After pre-expansion, it must be placed for a period of time. On the one hand, it is dried, and on the other hand, it is allowed to infiltrate air to eliminate negative pressure. The beads are elastic. The process of drying, cooling and stabilizing the cell pressure of the EPS beads just out of the pre-expander is called maturation. Maturation improves the further expansion of the pre-expanded beads during the molding process, the fusion between beads and the elasticity of the beads, which is beneficial to improve the quality of EPS products.
