注塑工藝方面應注意的問題(包括注塑機的要求)
為提升內應力和表面質量,在注塑工藝方面應注意以下幾點。
1.應選用專用螺桿、帶單獨溫控射嘴的注塑機;
2.注射溫度在材料不分解的前提下,宜用較高注射溫度;
3.注射壓力:一般較高,以克服熔料粘度大的缺陷,但壓力太高會產生內應力造成脫模因難和變形;
4.注射速度:在滿足充模的情況下,一般宜低,能采用慢一快一慢進行多級注射;
5.保壓時間和成型周期:在滿足產品充模,不產生凹陷、氣泡的情況下;宜盡量短,以盡量減低熔料在機筒停留時間;
6.螺桿轉速和背壓:在滿足塑化質量的前提下,應盡量低,防止產生解降現象;
7.模具溫度:制品的冷卻好壞,對質量影響極大,所以模溫一定要能精確控制其過程,有可能的話,模溫宜高一些好。
