Aluminum permanent mold castings share many attributes to its sand casting counterpart, but often prevail when a casting requires higher strength, improved cosmetics, larger in size (larger than 20inches), or when using a mechanical steel core can reduce costs. The process utilizes a reusable steel or iron mold, creating a smoother finish than its sand counterpart. A product made via permanent mold casting typically increases mechanical properties by 15% due to the reduced grain structure created by the freeze rate of steel versus sand. Many OEM’s leverage permanent mold casting strength for conversions from iron or steel castings to lighter aluminum permanent mold casting. While not at the same level of mechanical properties, advancements in alloying and heat treating make this feasible in many applications.
Each step of our manufacturing process is carefully monitored and controlled to guarantee that your specifications are met. We use the latest technology to check the chemistry of our metal from start to finish. Computers are used extensively throughout the foundry operations — controlling everything from the metal quality requirements to regulating die temperatures. Real time x-ray, die penetration analysis and mechanical property testing are performed regularly to ensure that we meet or even exceed your requirements.
