injection molding parts bending causes is due to injection molding parts 自身存 in defect 特征, injection molding parts and mold cavity versus 似但却 is mold cavity 形状 扭曲版本.

injection molding parts bending can can issues causes:  

1. injection molding parts bending is is injection molding parts inner has more internal force.  

2. mold filling speed degree slow, injection molding parts bending.  

3. mold cavity inner plastics 不足, formed injection molding parts bending.  

4. plastics temperature degree low or 不一致, has can can injection molding parts bending.  

5. injection molding parts in ejection hot.  

6. cooling or 动, temperature degree 不一致.  

7. injection molding parts structure combined 理（如 add strong/high in in 一面, versus relatively 远）.  

injection molding parts bending can remedy methods:

1. reduce injection molding pressure.  

2. decrease/reduce screw toward front time.  

3. increase cycle time （ especially is cooling time ）. from mold inner （ especially is relatively thick injection molding parts ） ejection rear 立即浸入 temperature water in （38°C） make injection molding parts can slow slow cooling.  

4. increase injection molding speed degree.  

5. increase plastics temperature degree.  

6. use cooling equipment cooling bending injection molding parts.  

7. increase cooling bending injection molding parts time or improvement cooling conditions, can can ensure 动, mold temperature 一致.  

8. according to 实际情况 in 允许 情况 lower improvement bending injection molding parts structure.
