It can be summarized into the following four points, directly related to the performance and lifespan of the mold:

1. Facilitating demolding

By sandblasting, uniform microscopic pits (pear-shaped patterns) are formed on the mold surface, reducing the contact area between the plastic/rubber and the mold, preventing products from sticking to the mold, and thereby reducing the amount of demolding agent used.

2. Cleaning stubborn stains

Efficiently removing plastic carbonization, tar, rust, and high-temperature oxide scales remaining after mold use, restoring the original accuracy of the mold.

3. Reducing surface brightness

Eliminating the scratches or reflections produced during mold processing, achieving a matte/frosted effect, meeting the appearance requirements of specific products (such as anti-reflective for automotive interior parts).

4. Stress release

Gently removing the tiny burrs on the mold edges and releasing the residual stress after fine processing, preventing the mold from cracking during production.
