Mold wear and galling countermeasures: Improved durability through precision polishing.

Mold wear and galling countermeasures: Improved durability through precision polishing.

Why do molds require "polishing"? The answer lies in the local pressure on the surface.

Many of the causes of mold failure lie in the surface irregularities. With appropriate surface treatment, we can reduce unexpected issues in the production environment. The main cause of wear in molds is localized pressure that occurs on the fine protrusions of the surface, leading to adhesive wear (seizing). Precision polishing of LSI removes these protrusions, disperses the pressure, and significantly delays the progression of wear. Additionally, by lowering the coefficient of friction, we can prevent sudden issues such as breakage and chipping, supporting stable operation of the production line. 【Wear Countermeasures】 ■ Benefit 1: Reduces localized pressure and delays wear progression ■ Benefit 2: Lowers the coefficient of friction, extending mold lifespan ■ Benefit 3: Reduces unexpected issues such as breakage and chipping *You can download materials summarizing the analysis of wear mechanisms and countermeasure examples.
