山东模具加工过程中出现气泡的原因?

文章发布:admin 发表时间:2017-04-27 15:03:56

山东塑料外壳在我们的生活中很常见,但是山东模具加工的方法却是比较复杂的。我们在进行山东模具加工时,往往会遇到各色各样的问题,其中气泡问题是所有塑料外壳加工中较为常见的一类。那么,山东塑料外壳加工产生气泡都是由哪些原因造成的呢?Shandong plastic shell is very common in our life, but the method of Shandong mold processing is more complex. We are in Shandong mold processing, often encounter the problem of the bubble problem in diversiform, is a common type of all plastic shell processing. So, what are the reasons for the formation of bubbles in Shandong plastic casing processing?

1.山东模具加工的生产工艺和设备导致的气泡产生,比如料筒温度过高、注射压力、背压太低、冲模料量不足等等,这些原因都会导致山东塑料外壳加工产生气泡。Production process and equipment of Shandong mold processing leads to bubbles, such as barrel temperature, injection pressure, back pressure is too low, the die material shortage and so on, these reasons will lead Shandong plastic processing bubble.

2.材料导致的山东塑料外壳加工产生气泡,比如材料的流动性和收缩性不符合标准、回料用量太多、原料没有完全干燥等都会导致山东模具加工加工过程中产生气泡。Shandong plastic material processing to produce bubbles, such as liquidity and contraction of the material does not meet the standards, to feed too much, not completely dry raw materials will have a bubble in Shandong in the process of mould processing.

3.模具因素导致的山东模具加工产生气泡,比如,壁厚处模温太高、浇口或流道不良、浇口类型或位置没有选择对,排除不良等都是会造成山东塑料加工外壳加工产生气泡的。 Shandong mold mold caused by bubbles, for example, the wall thickness at the mold temperature is too high, bad, gate gate or channel type or location have no choice to exclude bad, are caused by Shandong plastic shell processing bubble.
