PC料注塑工藝參數:
PC粘度高,流動性差。速度應盡可能快。壓力應適當為2113。但是,過大的壓力會引起塑料制品的內應力,從而容易變形和變脆。具體地,需要根據產品結構調整注入工藝5261。參考參數:機筒溫度:250?℃注射壓力:50?80MPa。
通常,噴嘴溫度為270?290,后段順序降低5?10度。模具溫度保證為60?95度。PC材料在約330℃開始氧化。當1653高溫熔融橡膠中的水分含量超過0.02%時,很容易使產品產生起花現象,并影響外觀和脆性損壞,從而影響沖擊強度。干燥專業,通常在120度下干燥3-4小時或更長時間。應力處理方法:首先在100-105°C的烤箱中烘烤10分鐘,然后在120-125°C的溫度下烘烤30分鐘,然后冷卻至室溫。
