Rapid Heat Cycle Mould (RHCM)- Rapid Heat Cycle Injection Mould
1. Technical Background of Heat & Cool Die
With the development of society, the progress of science and the improvement of people's living standards, especially in the industries of home appliances, communications, automobiles, daily necessities, medical quipment, etc., people have high requirements for the internal quality of plastic products, and the surface of plastic parts is high. Bright surface, lightness and thinness have also become the mainstream trend pursued by users, and the strength of plastics with 30%-50% glass fiber reinforced structure is also more and more accepted and common.
2. Technical principle of Rapid Heat Cycle Mould (RHCM)
The rapid cooling and rapid heating equipment heats the mold before injection, so that the mold temperature is quickly raised above the glass transition temperature of the plastic, and after the injection is completed, the mold temperature is quickly reduced to the ejection temperature. This is a molding process in which the mold temperature is variable during the forming process.This forming method takes advantage of the inherent characteristics of thermoplastics under high elasticity, which can effectively eliminate surface defects of plastic products, such as fusion lines, orange peel, and gas mark.Due to the higher molding temperature, the surface roughness of the plactic part is better than that of common forming.
