Fitmold make die casting die / tool / mold to enable our clients using them producing high quality alloy parts. (Aluminum alloy, zinc alloy, Magnesium alloy )
Die casting die / tool / mold is made the similar way as plastic injection mold. We use the same machine, the same processing methods. (Metal cutting, milling, EDM…ect). Considering the feature of alloy and the size and structure of alloy products, die casting die / tool / mold designs in different way. Beside that, the steel applied in Die casting die / tool / mold is "Hot work die / tool steel" which is hardened to enable it durable for high Temperature and pressure.
Compared to common plasitc, Liquid metal alloy (Aluminum alloy, zinc alloy, Magnesium alloy ) has worse fluidity. It callenges the die / tool / mold design, specifically the gating, the， the OVERFLOW.
The main cores, cavities, inserts and sliders of die casting die / tool / mold is rough mached by our NC equipment in the beginning. Then moved to processing the heat treatment. After that it will be continued to precision work, such as finishing milling, EDM, polishing, ect. All the steps are Irreversible. They should be done successfully one time.
