beplay全站app安卓制品缩水的成因
Causes of shrinkage of mould products
1.模腔胶料不足,引起收缩
1. The mold cavity is short of rubber, causing shrinkage
A.填充入料不足或加料量不够
A. Insufficient filling or feeding
B.浇口位置不当或浇口不对称
B. Improper gate position or gate asymmetry
C.分流道,浇口不足或太小
C. Diverter, insufficient or too small gate
D.制品壁厚或厚薄不均匀,在厚壁处的背部容易出现缩水
D. The thickness or thickness of the product is uneven, and the back of the thick wall is easy to shrink
2.工艺技术参数调节不当
2. Improper adjustment of technological parameters
A.射胶压力小,射胶速度慢
A. Low injection pressure and slow injection speed
B.射胶时间设置太短
B. The injection time setting is too short
C.保压时间设置太短
C. Pressure holding time setting too short
D.冷却时间设置帮短
D. The cooling time is set to be shorter
3.塑料过热
3. Plastic overheating
A.塑料过热,熔胶筒温度设置太高
A. The plastic is overheated, and the temperature of the melt glue cylinder is set too high
B.beplay全站app安卓温度过高
B. Mold temperature too high
C.beplay全站app安卓有局部过热或制品脱模时过热
C. The mould is overheated locally or when the product is demoulded
D.料温太低或塑化不良,使融料流动不良
D. Too low material temperature or poor plasticization, resulting in poor melt flow
制品缩水的解决方法
Solution to shrinkage of products
1.进行调节校正
1. Adjust and correct
A.增加加料或开大下料口闸板
A. Increase the feeding or open the gate of blanking port
B.限制熔胶全部流入直浇道浇口,不流入其他浇口
