Embodiment
[0018] Embodiment: The present invention provides a kind of LED lamp lens injection molding process, and this production process comprises the following steps:
[0019] (1) Development and design of injection mold: the mold core is smooth, and the product needs to have a refraction effect during mold design to meet the optical transmittance and spot requirements of the car light, so that the lens-type lamp head has uniform brightness and strong penetrating power;
[0020] (2) Selection of injection molding raw materials: PC raw materials mainly have good impact and transparency, good mechanical properties and insulation properties, wide service temperature, and high dimensional stability;
[0021] (3) Selection of injection molding machine: buy the original imported injection molding machine, and use the original imported electroplated optical grade screw;
[0022] (4) Injection molding process: 1. Drying treatment of raw materials; 2. Preheating treatment of injection molding...
