一, what is injection molding combined 纹

熔 combined in resin combined 流之处 has 开孔 部 separation 会出现.
                                  
二, combined generate causes

熔 combined generate main/primary has causes, separation is:

1, resin temperature degree low
                 
        2, pressure low
                
       3, gas 口 排 gas relatively low
             
三, injection molding combined solutions

1, improve/increase combined separation resin temperature degree

2, improve/increase holding pressure

3, 检查排 gas 口

检查排 gas thick degree and large small is ensure gas and is to 模垢 污染 and other. if gas separation, 则会造 formed gas 体烧焦并引发 other fault/failure.
