The mold temperature for PC injection molding can reach how many degrees?
The injection temperature must be considered comprehensively based on the shape, size of the product, mold structure, performance requirements, etc. Generally, a temperature between 270-320°C is selected during molding. If the material temperature is too high, such as exceeding 340°C, PC will decompose, leading to darker colors in the product, and surface defects like silver streaks, dark lines, black spots, and bubbles. Additionally, physical and mechanical properties will significantly decrease.
PC has excellent performance, high transparency, good impact toughness, resistance to creep, and a wide range of usage temperatures. The processing characteristics of PC are: low sensitivity of melt viscosity to shear rate but high sensitivity to temperature, no distinct melting point, higher melt viscosity, easy hydrolysis at high temperatures, and prone to cracking. In light of these characteristics, special attention should be given: to increase melt flowability, it's better to raise the injection temperature rather than increasing the injection pressure. It requires shorter and thicker runners and gates in the mold to reduce fluid pressure loss, along with higher injection pressure. Resin should be thoroughly dried before forming, controlling moisture content below 0.02%.
