How to solve the problem of easy breakage of die-cutting waste material


l Waste edge is too thin, material strength is not enough

There are many die-cutting manufacturers in order to maximise the pursuit of economic benefits in the material slitting, the waste side of the calculation is too small, resulting in die-cutting processing material waste edge strength is not enough to lead to breakage. Generally speaking, the cushioning foam material waste edge width requirements in more than 3mm, it also depends on the die-cutting materials, backing film waste edge width requirements of at least 1mm or more.

l The product is too small to peel

Sometimes masters in the process of waste discharge will find it easy to bring up the phenomenon of the product, which indicates that the peeling force is too light, you can choose to peel a little heavier peeling force to try; if the peeling force can not be peeled off or peeled off poorly such a situation is also very normal, because the product area is too small, the peeling force in the peeling force is not light enough when it is easy to cause deformation and other phenomena, so change the peeling force of the lighter material.

l off force is too large

There are many unqualified die-cutting processing material release force is too large, some even want to separate the surface layer and base paper are very difficult, such as double-sided tape and release paper can not be separated, because many manufacturers in order to covet the convenience, not in strict accordance with the provisions of the selection of the appropriate release paper with the release paper, but all with a type of release paper to die-cutting, resulting in poor peeling. Such die-cutting material in the die-cutting waste discharge due to the waste side of the tension is less than the material's release force is also easy to break. Therefore, it is better to check whether the release force is qualified before die cutting.

l Material edge breakage

The edge of the material caused by die-cutting processing broken transport and cutting two reasons, so in the process of transport and cutting materials must pay attention to avoid bumping and cutting neatly, do not give the subsequent die-cutting process to cause trouble.

l waste roller is too thin

For some of the waste roller is too thin die-cutting processing equipment, due to the waste edge through the waste roller when the tension is too large it is easy to pull off the waste edge. For this reason caused by the waste edge breakage we can use to replace the waste roller or in the waste roller wrapped in a layer of sponge to thicken its diameter to solve.

l Waste tension is too large

In the die-cutting process, if the operator waste tension is too large will also cause the waste edge breakage, according to the die-cutting material should be appropriate to use the waste tension size.

l Improper selection of release material

Take release paper as an example: the structure of release paper can be divided into two kinds: PE coated and without PE coating. Coated PE coating has two advantages: one is to seal the pores on the paper surface so that it is smooth and flat, coated with silicone oil, reduce the amount of coating, can reduce costs; the other role is to improve the die-cutting characteristics, because the PE coating is equivalent to a layer of cushioning pads, a certain degree of toughness and elasticity, which reduces the breakage of the release paper. So with PE coating of the release paper, anti-breakage performance is much higher than without PE coating of the release paper material.
