This product is a reducer housing die casting mold, mainly used to produce aluminum reducer housings, transmission cases, and power system connection parts. The product usually includes circular shaft holes, flange connection surfaces, mounting holes, reinforcing ribs, and internal cavity structures. It must ensure housing strength, shaft hole concentricity, sealing surface flatness, and dimensional stability. Mold design should properly plan gate locations, venting channels, core-pulling mechanisms, and cooling systems to reduce porosity, shrinkage, deformation, and demolding problems. It is suitable for industrial equipment, automation machinery, motor accessories, transmission systems, and general machinery industries.
