Junying Metal Polishing Services – Polishing Surface Treatment for Die Casting Products

Based on decades of experience in mold making and metal die casting service, we know that aluminum polishing service is important to aluminum casting because the die casting products are often rough after the manufacturing and require surface treatment to get smoother edges, preciser measurements and better surface quality. Metal polishing services at diecasting-mould.com are our major finishing services to improve the exterior of your aluminum die castings and other alloys die cast parts. Polishing surface treatment can remove parting lines and overflows from the die casting process, and heat checking or die washout on old casting surfaces, as well as enhance the safe treatment and increase the aesthetics of die casting components. The accomplished team at Junying die casting plant will follow the safety guideline and industry practices to deliver high-quality polished castings. We can transform your design into a fully finished product all in-house.

What is Metal Polishing?

Polishing is a finishing operation designed to refine the outer layer of a metal part by rubbing it against an abrasive medium or a rotating wheel. The process serves several practical purposes: it enhances outward appearance, guards against dirt or fingerprints, eliminates surface oxidation, and boosts shine or reflectivity. Though people often use the terms interchangeably, polishing differs from buffing. In polishing, the abrasive is bonded directly to the wheel’s surface, while in buffing, loose grit is sprinkled onto the wheel during operation. A typical polishing procedure employs a soft pad sprinkled with fine or ultra-fine powder combined with a small amount of polishing compound fluid. Together they produce the glass-like finish that many users seek. Because the technique is meant to refine rather than reshape, only the tiniest fraction of base metal is removed, just enough to fill scratches and level the surface. The condition of the substrate before work begins dictates the choice of abrasive grade. Finished components, such as polished aluminium die-cast housings, are frequently treated with a protective coating of wax, oil, or clear lacquer to hinder further oxidation and prolong service life.
