模切泡棉胶产品有残胶怎么办?处理对策!

现在模切模切泡棉胶产品有残胶的话需要进行分析,因为残胶/溢胶是模切操作中常见的问题,而且造成这种问题的因素很多,可能是材料的原因,也可能是模切环境的原因,也可能是模切操作的原因等等。

一、残胶产品处理对策

残胶/溢胶:模切后切口边缘不光滑,有不规则残胶。

原因:模切深度没有完全切透胶面,导致废料被撕掉。

重新调整模切刀模深度至合适。

原因:叶片角度过大(叶片磨损)或过小;因为胶带有弹性,切割宽度越大,胶带对刀片的挤压越大。模切时间长了,刀片上有胶。再次模切时,刀片上的胶与材料胶相互作用,这样如果角度太小,在容易膨胀和改变平整度的前提下,模切后很容易再次粘合。

二、处理对策

1,复合好的材料冷藏1小时以上,刀模用内置外斜偏锋刀,产品冲切、成型等在20度室温,完成的成品在转入10度以下环境中储存,

2,对于胶带,厚度在0.1MM以下的模切角度60度可以保证模切刀的寿命和精度,而厚度在0.1 mm以上的模切刀建议65~70度,模切后要注意尺寸对比是否正确,刀片高度要高于60度模切的刀片高度。

原因:有些刀模垫有泡棉胶的地方,如果泡棉垫太厚,也可能造成这种情况。叶片抬起后,仍有泡棉作用在材料上,会再次被挤压粘合。

改进对策:加垫泡沫是制作胶带的必要条件,但要注意厚度。原则上比刀片高0.2~0.3MM是最佳选择。
