Sand hole: keep wax and gate rod clean, prevent mold shell from falling into cavity during dewaxing, handling, storage, roasting, pouring or sand filling. Shrinkage: adjust alloy composition, reduce alloy solidification range, fully deoxidize and degassing during melting and pouring to reduce the effect of gas on solidification shrinkage improve casting structure, set pouring system reasonably, increase pressure head height and increase shrinkage capacity select suitable pouring process, strictly control pouring temperature of molten metal select good thermal conductivity shell material, improve cooling condition of castings and speed up cooling rate of castings improve the position of inner gate, which is beneficial to sequential solidification. Shrinkage: correct design of gating system to facilitate casting and sequential solidification and shrinkage improvement of casting structure to make wall thickness as uniform as possible or increase process subsidy and cold iron use of appropriate pouring process, such as high temperature, low temperature pouring increase mold cooling rate, or reasonable mold formation, increase wax mold spacing and improve local heat dissipation conditions reduce molten metal temperature during pouring and increase the height of pressure head select smelting alloy with low shrinkage if necessary. Porosity: the charge should be cleaned, the ferroalloy should be baked well, the ladle should be baked well during pouring the overheating temperature and time of molten metal should be controlled by reasonable melting process, the cooling rate of castings should be accelerated, or solidified under pressure, and the gas should be precipitated the appropriate pouring process, gating system and pouring conditions should be selected to facilitate the discharge of gas the air permeability of the mold shell should be improved, and the exhaust hole should be added when necessary the suitable temperature of molten metal, pouring temperature and baking temperature of the mold shell should be added the roasting mold shell should be fully roasted the particle size of binder and refractory should be reasonably selected.

Hole defects include porosity, shrinkage, shrinkage, slag hole, sand hole, iron bean. We are working for the result that no matter you want to create housing casting, low carbon steel casting, or stainless steel investment casting, once you searched “Metal Casting China”, you will find our steel casting company. For example, housing stainless steel investment casting.Ĭompared with other steel casting manufacturers, we are trying to produce “Best Metal Casting China” and improve our steel casting company to be better. With our steel casting foundry and precision casting services, you will achieve a flexible combination of parts, materials, and casting methods.
