How does the EPS molding machine work?
Plastic injection molding technology was developed in the late 19th and early 20th centuries based on the principle of die casting. This is one of the methods commonly used in plastic processing. This method is suitable for all thermoplastics and some thermosets (about 1/3 of the total plastic).
The EPS molding machine works like a syringe. It is the process of injecting plastic in a plasticized and molten state (that is, a viscous flow state) into a closed mold cavity through the thrust of a screw (or plunger), and then solidifying and molding to obtain a product.
Injection molding is a cyclic process, each cycle mainly includes: batching, melt plasticization, pressure injection, mold filling and cooling, mold opening and removal. After removing the plastic parts, close the mold and go to the next cycle.
EPS foam machine cutting machine is mainly used for cutting and processing foam, sponge and other chemical materials. Currently this laser is mainly used for cutting. Because the laser beam precision cutting is not easy to deform, the cutting surface is smooth and the edge is clear, it has been used in various fields. Of course, in the process of using the EPS foaming machine cutting machine, there will also be some failures, which need to be repaired from time to time. Then let's talk about how to repair the EPS foaming machine. It is worth reminding here that only people who know how to use and operate can carry out maintenance and parts replacement of the foaming machine. EPS molding machine mechanical method: With the help of strong stirring, a large amount of air or other gas is introduced into the liquid plastic. In the industrial field, urea-formaldehyde foam is mainly produced in this way, which can be used for thermal insulation of thermal insulation materials, and can also be used for sets in film and television dramas, such as our common artificial snowflakes.
In order to prevent accidents or machine damage, the following principles must be observed during the inspection of EPS molding machines:
1. When the EPS molding machine fails, immediately disconnect the power supply and stop.
2. When the EPS molding machine cannot be used normally, please consult the relevant manuals and take correct measures. Turn off the power before checking and replacing components.
3. The parts removed during the inspection should be replaced with the same new parts in the same position. Instruments used in the inspection process must be calibrated.
4. It is strictly forbidden to place flammable or metal objects in the electrical cabinet or junction box;
5. Regularly check cables and wires to prevent leakage or electric shock.
