Precision die casting parts manufacturer need to pay attention to the following several points in the production process:
1. From the beginning of the procurement alloy ingot, the supplier must have strict standards for components. High quality alloy material is the production of high quality castings guarantee.
2. Alloy ingot stacking area to ensure clean, dry, to avoid long time exposure to moisture and generated white rust or be dirt pollution of the factory, otherwise it will increase the loss of metal. The clean factory environment is very useful for the effective control of the alloy composition.
3. Ratio of new materials and returns, returns no more than 50%, new materials : old material =70:30. Continuous remelting of the important elements in the alloy decreased gradually.
4. When drainage opening material was remelted, must strictly control the remelting temperature of not more than 430 °C, in order to avoid the loss of alloy elements.
5. When remelting cannot have the tin galvanizing, the soldering tin and the lead polymer.
6. If the condition allows, die casting parts manufacturer can be used to centralized furnace melting alloy material, the alloy ingot and the returns ratio is uniform, the flux can be effectively used, the alloy composition and temperature uniformity and stability. Electroplating waste and fines should separate melting.
