Polishing the mold surface to a mirror finish is a crucial step in mold making. It not only gives the product an aesthetic appearance, but also significantly improves its performance properties.

The objectives of polishing:

1. To make the surface perfectly smooth. Polishing allows you to achieve a perfectly flat and smooth surface, which greatly simplifies the removal of parts obtained by die casting and reduces the production cycle time.

2. Improve surface quality. Mirror polishing ensures high precision and surface quality, which is especially important for parts used in the automotive, food, and consumer industries.

Polishing process:

Diamond grinding and polishing: This procedure is performed under light pressure, especially when working with pre-hardened steel and fine-grained abrasive paste.

Use of clean tools: The cleanliness of the work surface and the hands of specialists is the key to high-quality polishing. Tools and the hands of specialists should be thoroughly cleaned to avoid the ingress of large particles.

Advantages of mirror polishing:

1. Aesthetic appearance. Mirror polishing gives molds an attractive appearance, which is especially important for products used in the automotive and food industries.

2. Improved performance characteristics. Polishing increases the corrosion resistance and wear resistance of the material surface, which significantly extends the service life of the molds.
