Technology
The types of transparent plastic materials commonly used in the market are: polymethyl methacrylate (acrylic or plexiglass PMMA plastic), polycarbonate (PC plastic), polyethylene terephthalate (PET), transparent nylon, AS (Acrylonitrile-styrene copolymer) etc. Among them, the three plastics that we are most exposed to are PMMA, PC and AS.
1. The properties of transparent plastics: firstly, transparent plastics must have high transparency, and secondly they must have certain strength and wear resistance, impact resistance, heat resistance, chemical resistance, and water absorption. In use, it satisfies the requirements of transparency and has stable performance.
2. Process characteristics of PMMA. PMMA has high viscosity and poor fluidity. Therefore, high material temperature and high injection pressure must be used for injection molding. The influence of injection temperature is greater than injection pressure, but the increase in injection pressure will help improve the shrinkage rate of the product. Poor impact resistance, poor wear resistance, easy to scratch, easy to brittle, so the mold temperature should be increased, and the condensation process should be improved to overcome these defects.
3. Process characteristics of PC. PC has high viscosity, high melting temperature and poor fluidity, and its manufacturability is not as good as PMMA. The injection pressure has little effect on the fluidity, but due to the high viscosity, the injection pressure is still higher. Correspondingly, in order to prevent internal stress, the pressure holding time should be as short as possible. The shrinkage rate is large, the size is stable, but the internal stress of the product is large, and it is easy to crack.
4. Process characteristics of PET. PET molding temperature is high, and the material temperature adjustment range is narrow (260-300°C), but after melting, it has good fluidity, so the manufacturability is poor, and it is often necessary to add anti-spreading devices in the nozzle. The mechanical strength and performance are not high after injection, and the performance must be improved through the stretching process and modification.
