Precision cast steel parts

Precision steel castings refer to the general term for the process of obtaining precision dimensional castings.Compared to traditional sand casting technology,precision steel castings obtain more accurate casting dimensions and better surface smoothness.It includes investment casting,ceramic casting,metal casting,pressure casting,and lost foam casting.

Precision cast steel parts,also known as wax loss casting,have products that are precise,complex,and close to the final shape of the parts.They can be used directly without or with little processing,and are an advanced technology for near net forming.

In ancient China,the Prince Wu Ding,Bronze Forbidden,Bronze Lion,and so on were all masterpieces of investment casting.Since investment casting was used in industrial production in the 1940s,it has been developing at a fast pace for half a century.Especially in European and American countries,there is rapid development.Investment casting is used outside the aviation and weapons sectors,and is almost applied to all industrial sectors,especially electronics,petroleum,chemical,energy,transportation,light industry,textiles,pharmaceuticals,medical equipment,pumps,and valves.In recent years,China has also developed rapidly.

The development of investment casting technology enables it to produce not only small castings,but also larger castings.The contour size of the largest investment casting is nearly 2m,while the minimum wall thickness is less than 2mm.At the same time,investment casting is becoming more precise,and in addition to linear tolerances,parts can also achieve higher geometric tolerances.The surface roughness of investment casting is also decreasing,reaching Ra0.4μM.
