PC材料的注射成型
产品详细信息
PC材料的注射成型。注射温度根据原材料的分子量、产品的形状和尺寸以及注射成型机的类型进行调整
2。对于多级注射，注射速度最好采用慢速法
3。注射压力取决于产品的形状和尺寸。柱塞式注塑机一般为100-160MPa，螺杆式注塑机为70-140MPa
4。成型周期取决于产品的壁厚和注射量。在正常情况下，填充时间短，保持时间长，冷却时间基于产品在脱模过程中不变形的原则
但是
5。模具温度取决于产品的形状和厚度。适当提高模具温度有利于脱模和提高产品质量
6。产品后处理：对于形状复杂、金属嵌件、温度极低或极高的产品，必须进行后处理以消除或降低内应力
方法：将产品放入干燥箱后，将温度升高，并在室温下保持10-10分钟至100-105°C。继续加热至120-125，保温30-40分钟，然后缓慢冷却至60°C以下并取出

injection molding of PC materials
Precautions for injection molding of PC materials
1. The injection temperature is adjusted according to the molecular weight of the raw material, the shape and size of the product, and the type of injection molding machine.
2. The injection speed is best to use the slow-slow method for multi-stage injection.
3. The injection pressure depends on the shape and size of the product. Plunger injection molding machine-generally 100-160MPa, screw injection molding machine 70-140MPa.
4. The molding cycle depends on the wall thickness and the injection volume of the product. Under normal circumstances, the filling time is short, the holding time is long, and the cooling time is based on the principle that the product does not deform during demolding.
but.
5. The mold temperature depends on the shape and thickness of the product. Properly increasing the mold temperature is conducive to demolding and improving product quality.
6. Product post-processing: For products with complex shapes, metal inserts and extremely low or extremely high temperatures, post-processing must be carried out-to eliminate or reduce internal stress.
Method: After the product is put into the drying box, the temperature will be increased, and the temperature will be kept at room temperature for 10-10 minutes to 100-105°C. Continue to heat to 120-125, keep it warm for 30-40 minutes, then slow
Slowly cool to below 60°C and take it out.
