薄壁HDPE桶用热流道点浇口式模具

Pin-Point Gate Type Hot-runner Mould for Thin Wall HDPE Buckets

本文介绍了采用热流道点浇口式模具成功注塑薄壁塑料桶的经验,详细分析了点浇口与注射速率、压力、流动性、流程比等因素之间的相互关系并阐述了点浇口的设计公式。

In this paper,the successful experience of Using pin-point gate type hot-runner mould in thin wall HDPE buckets moulding was introduced.Therelationships between pin-point gate and injection rate,injection pressure,melt flowability,and flow path ratio,etc.were analysed in detail,the formulafor the design of pin-point gate were described as well.
