Release failure due to mold release resistance ②

The smaller the mold release resistance, the better for mass production.

So, how can we make it smaller?

How does mold release resistance occur in the first place?

Molds are generally processed by cutting tools or electric discharge. The surface of the mold has fine irregularities left by the cutting tools and electrical discharge. The resin penetrates into these fine irregularities, and the mold and resin adhere to each other due to the anchor effect. Furthermore, in the case of a product with deep ribs, as in this case, the surface area where the mold and resin come into contact with each other becomes large, which is thought to be a mold release resistance.

In other words, to reduce mold release resistance, it is important to flatten these uneven surfaces. We use IEPKO equipment for surface treatment, which makes it possible to create a uniform uneven surface.
