Dongguan dongguan precision casting, precision casting and mold temperature control application temperature can effectively ensure the melt in the injection process has a good liquidity. Stainless steel precision casting temperature selection need according to the distance of casting, casting process of cooling and the flow to determine in the process of casting. Dongguan precision casting round ingot crack tendency is low, can effectively guarantee the alloy has good ability of exhaust and contraction. It can create close to its order and increase its density. Generally high casting temperature, casting 350 mm above the casting temperature is 730 ~ 75. Zero degrees centigrade. Due to dongguan precision casting size small, when using, its mechanical performance is good. In general, to a certain extent, can satisfy its liquidity, not bright crystal formation, average temperature is 715 ~ 740 ℃. Stainless steel precision casting slab with high tendency of hot tearing, stainless steel precision casting temperature is low, accordingly general for 68. 0 ~ 735 degrees. Dongguan precision casting according to different shapes and efficiently manufacture of moulds. The cast of the product can effectively divided into upper die and lower die, and the integration process through milling, etching, edm, etc. Pits the shape and size of the consistent with the product side. Dongguan precision foundry production of the first layer of fine sand under the set temperature dry naturally, but will not affect the shape of the wax models in change. Natural wind drying time depends on the internal complexity of the product itself. For the first time of pouring air drying time is about 5 ~ 8 hours. Dongguan precision casting will effectively fix the baking process effectively in the mold, then sand drying process of wax models effectively to its special heating furnace, metal enclosed for industrial wax melting point is not high, the temperature is about 150.
