产品详细信息

聚丙烯塑料材料注射成型

抗静电聚丙烯塑料材料注射成型工艺：流道和浇口：流道直径为4-7mm，针阀长度为1-1。5mm，直径可小至0.7mm。边缘浇口的长度尽可能短，约为0.7mm，深

度为壁厚的一半，宽度为壁厚的两倍，且腔内熔体流动的厚度增加。模具必须具有良好的排气性能，排气孔的深度为

<0.025mm-0.038mm，厚度为1.5mm，为了避免收缩痕迹，必须使用大的圆形喷嘴和圆形流道，并且加强筋的厚度较小（例如，壁厚为50-60%）。均聚物PP制成的产品厚度不应超过3mm，否则会产生气泡（厚壁产品只能与PP共聚），熔融橡胶的背压可以是

调色剂的背压可以通过使用5巴熔融橡胶作为背压进行适当调整。产品后处理：为了防止后结晶引起的收缩和变形，产品通常采用热水浸泡处理

Product Details

PP plastic material injection molding

Antistatic PP plastic material injection molding process:

Runner and gate: the diameter of the runner is 4-7mm, the length of the needle valve is 1-1. 5mm, and the diameter can be as small as 0.7mm. The length of the edge gate is as short as possible, about 0.7mm, deep

The degree is half the wall thickness, the width is twice the wall thickness, and the thickness of the melt flow in the cavity increases. The mold must have good exhaustability, and the depth of the vent hole is

0.025mm-0.038mm, thickness 1.5mm, in order to avoid shrinkage marks, large and round nozzles and circular runners must be used, and the thickness of the ribs is small (for example, wall thickness

Of 50-60%). The thickness of the product made of homopolymer PP should not exceed 3mm, otherwise it will produce bubbles (thick wall products can only be copolymerized with PP), and the back pressure of the molten rubber can be

The back pressure of the toner can be adjusted appropriately by using 5 bar of molten rubber for back pressure. Product post-treatment: In order to prevent shrinkage and deformation caused by post-crystallization, the product is usually

Hot water immersion treatment.
