Polycarbonate Injection Molding Process
Melt Temperature: Polycarbonate typically melts at temperatures between 270°C and 320°C.
Mold Temperature: The mold temperature should be between 80°C and 120°C to ensure proper filling and reduce the risk of part defects.
Drying: Polycarbonate is hygroscopic, meaning it absorbs moisture from the air. It must be dried before molding (usually at 120°C for 4-6 hours) to avoid issues like hydrolysis, which can lead to brittle parts.
Injection Pressure: High injection pressure is required due to the material’s high viscosity.
Cooling: Polycarbonate has a lower shrinkage rate than many plastics, meaning the cooling phase helps achieve dimensional accuracy with minimal part distortion.
