[Preferred] How does the foam forming machine work? How to use the foam machine

We already know about foam building module equipment, foam building module equipment, manufacturers, manufacturers and other issues. What about 'how does the foam molding machine work and how to use the foam machinery'? It is estimated that many people are not familiar with it. Today we will get familiar with the experts! The working principle of the molding machine is similar to the syringe used for injection. It uses the thrust of the screw (or plunger) to inject the plasticized plastic in the molten state (that is, the viscous fluid state) into the closed mold cavity. The process of obtaining the product after curing and shaping. How to use the forming machine: 　　 1. Choose a flat table and stabilize the machine. The legs of the forming machine can be pulled apart to make the machine panel easy to observe.　　 2. Insert the plug on the hand-held sensor head into the socket on the panel and tighten it. Pay attention to the positioning gap.　 3. Insert one end of the plug of the power cord into the socket on the rear panel of the chassis, and the other end into the power supply socket. Be sure to use a single-phase three-wire power supply.　 4. Turn on the 'main power switch' on the back panel of the molding machine, press the 'power switch' button on the panel, wait for the 'ready' green indicator light to turn on the foam, and the machine can work on how the foam molding machine works. You may be interested in the article: Foam machinery equipment retains a certain amount of foaming agent and water vapor in the beads after the pre-expansion. The pressure in the bubble drops quickly, negative pressure (partial vacuum) appears 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. 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. 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. The beads of the foam mechanical pre-expander are wet. After being discharged from the pre-expander, it absorbs air and suddenly encounters cold, causing the foaming agent in the honeycomb cells to condense and form a negative pressure in the cells, so the beads are in It must be placed for a period of time after the pre-expansion. On the one hand, it is dried, and on the other hand, it is allowed to infiltrate the air to eliminate the negative pressure, so that the internal pressure and external pressure in the cells are balanced, so as to prevent the cells from collapsing and make the beads 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.
