磨砂盖塑料产品的注塑工艺
摘要：
本发明公开的磨砂盖塑料产品的注塑工艺至少包括如下工艺过程：储料工段、挤出工段、开模、合模、注射、保压，其中执行注塑的模具其热流道的温度区段包括：第一区段277‑280℃、第二区段277‑280℃、第三区段270‑275℃、第四区段285‑290℃、第五区段273‑278℃、第六区段270‑275℃。本发明通过对磨砂盖塑料产品的注塑工艺中各个区段工艺参数的精确控制，从而不仅实现了对注塑流体质量的把控，还提高了注塑产品的质量和注塑效率，降低报废率。
摘要（英）：

The invention discloses a frosted cover plastic product injection molding process which comprises at least the following process steps: a storage procedure; an extrusion procedure; mold opening; moldassembly; injection; and pressure maintaining, wherein a hot running of a mold used for injection molding comprises the following temperature sections: a first section of 277-280 DEG C, a second section of 277-280 DEG C, a third section of 270-275 DEG C, a fourth section of 285-290 DEG C, a fifth section of 273-278 DEG C, and a sixth section of 270-275 DEG C. Through the precise control of processparameters of all the sections in the frosted cover plastic product injection molding process disclosed by the invention, not only can the injection molding fluid quality control be achieved, but also the injection molding product quality and the injection molding efficiency can be improved, and the scrap rate can be lowered.
