Permanent Casting Molds

Gravity casting method; It is a method to be preferred in complex and mass production. In the permanent mold casting method, special quality steel is used as the mold material. Considerations include mold cavity shrinkage, air ducts and feeder features. After the heat transfer is calculated in detail and 3D simulation is done, the wall thicknesses are determined and mold production is started. As Grup HS company, we deliver molds without any problems in such molds, the opening and closing units of which are usually made hydraulically, with the competence we have gained from our experience. Although casting molds are designed theoretically and systematically, the most important aspect of design is experience in mold and our company has this experience as a mold manufacturer since 1987.

In mold making, mold cavity and air channels are processed and opened. In determining the wall thickness of the molds, heat inputs and outputs must be taken into account.

Since the intergranular gaps in the parts produced with the permanent mold casting mold will be less compared to the sand casting, their mechanical properties are better. Dimensional tolerances are very high and it allows the production of complex parts. Although it is a suitable method for mass production, the surface smoothness of the parts is high.
