How can stainless steel precision casting products achieve high quality

Edit:Xiangyang Liqiang Machinery Co., Ltd.UpDate:2020-01-22

Stainless steel precision casting products can be divided into two categories: military, airline products and cargo products. The former one has high quality regulations, and the latter one is not as good as the former one. Nowadays, precision castings are basically used in aviation, aerospace, and military industries, but are basically used in all industrial sectors, such as electronic devices, crude oil, chemical plants, electric energy, road transportation, light industry, textiles, pharmaceuticals, medical machinery, etc.

When aluminum die-casting, metal material must be used. It is a permanent forging process, which is different from precision castings. Because castings are mostly made of aluminum alloy profiles or die-cast aluminum and alloy copper metal materials with lower melting points. Precision castings belong to one-time metal mold castings. The key is stainless steel plates, titanium metal, heat-resistant alloys, cast steel valves and other high-line melting point metal composite materials. It is not easy to have sand holes during aluminum die-casting. If stainless steel precision casting is operated properly, sand holes are not easy to appear. Refining is a kind of name for gravity casting of aluminum alloy. It is actually a forging process carried out under force. Forging processes other than working pressure forging must use the aluminum gravity casting method.

At the molding level, it seems that most and every stage of stainless steel precision casting can endanger the quality of castings. Therefore, if you want to improve the quality of castings, you must strictly supervise the important links and the actual operation staff must have high Accomplishment, only by mastering all the important links, can the quality of castings stabilize and produce qualified products. Secondly, the quality of castings is also closely related to the raw materials used. If the quality of the raw materials is high, the quality of the manufactured castings will be high, and the opposite is the same. Therefore, when purchasing, you must ask clearly what kind of stainless steel plate the casting is made of. For example, products made of 304 stainless steel plate are very prone to rust and mildew when placed in a relatively humid and cold area.
