Polycarbonate (PC) is a thermoplastic engineering plastic with high strength, high transparency, high temperature and impact resistance. Its excellent physical properties and weather resistance make Polycarbonate injection molded parts widely used in many fields.The light transmittance of PC material can be as high as 90% or more, and has excellent UV resistance, which can effectively extend the service life of the product.
1.Xiamen Goldcattle polycarbonate injection molding parts manufacturing process
Raw material preparation
Select the polycarbonate granule that meets the requirements, and add coloring agent, anti-ultraviolet agent, reinforcing agent and other additives as needed.
Dry the raw materials as necessary to remove moisture and ensure the quality of injection molding.
Injection Molding
Polycarbonate injection molding requires high injection and mold temperatures, generally between 260°C and 320°C. The injection is performed at high pressure to fill the molten PC plastic.
High-pressure injection fills the mold with molten PC plastic, ensuring dimensional accuracy and appearance quality of the product through precise control of injection speed, pressure and temperature.
The cooling phase needs to be carried out patiently to prevent deformation or internal stresses in the part.
Mold Design
The mold design needs to take into account the high fluidity and high transparency characteristics of polycarbonate to ensure that the surface of the product is smooth and free of bubbles and silver lines.
Reasonable runners and gates are designed to minimize shear heat and flow traces to improve the appearance quality of the product.
Post-processing
Remove burrs, flying edges and other defects on the injection molded parts, and carry out necessary grinding and polishing treatment.
For products requiring higher surface quality, surface treatment processes such as coating and spraying can be carried out.
