Internal Polishing ► 【ALGOVISION TECHNOLOGIES INC.】

In fact, even if you do physically unreasonable processing, it will not lead to the good results you are looking for.

This is because the optimal polishing method changes depending on the material and shape. In fact, we have been able to do things that other companies couldn’t do. In particular, there is a difference in the polishing of medical equipment parts, 3D metal modeling products, and cemented carbide products.

Among the increasing use of AM products for “molds”, “precision parts” and “aerospace parts” in recent years, there are many products with fine holes. In particular, it is a sample product that can prove that it is possible to solve problems such as clogging removal and surface roughness improvement.

Many AM molds use maraging steel, and there have been many cases of mold cracks due to “rust” and “clogging.” As a countermeasure, the inside of the flow channel is polished to solve the problem of contamination and clogging. Periodic polishing is expected to maintain cooling performance and extend mold life.
