Nowadays, the application of injection molding parts has been quite extensive, and more and more enterprises are engaged in injection molding processing. When we are processing plastic injection parts, we usually need to pay attention to the hardening speed of plastic injection parts. If the hardening speed is too slow, it will affect the processing efficiency of plastic injection parts. So, injection parts processing hardening speed are affected by what factors?
The hardening speed of injection parts is closely related to the type of injection parts processing materials, shape, wall thickness, molding temperature and whether it is preheated and prepressed, etc. For example, the adoption of ingot pressing, preheating, raising the molding temperature and increasing the pressure time and other measures can significantly accelerate the hardening speed. In addition, the hardening rate of injection parts should be suitable for the requirements of the molding method. For example, injection molding or injection molding, should be required in the plasticization, filling the chemical reaction is slow, slow hardening, has been maintained for a long time the flow state.
In addition, the mold should be rapidly hardened under high temperature and pressure after filling the mold cavity. The slow hardening speed of plastic injection molding will make the molding cycle longer and the productivity lower. Fast-hardening plastics do not form complex injection parts. Therefore, the hardening speed of injection parts must be strictly controlled in the process of injection parts processing.
