                        injection molding demolding defect issues is molding product method from mold in 取出 一 types phenomenon.  

            
一, defect generate causes

1, injection molding products in 塑孔栓 upper.

2, add strong/high or amount filling.
                       

3, in molding conditions upper, mold temperature degree low holding pressure large easy demolding defect.

4, mold 构造方面 issues, mold mold cavity products demolding degree small 时候, due to retardant force large, easy generate demolding defect. another, mold cavity surface light degree and loss degree 也会造 formed demolding defect.
二, demolding defect solutions

1, made 塑孔栓抱紧.

2, made add strong/high or 者轮毂 amount filling.

3, improvement injection molding mold.
