Cheapest Factory Granite Straight Ruler With 4 Precision Surfaces - Precision Casting – ZHONGHUI

With precision casting process, we can cast nearly 300 alloys. Our metals include stainless steel, tool steel, carbon steel and ductile iron,aluminum, copper, brass,and other alloy steels. Precision casting is suitable for complex and detailed part designs,such as impeller. Because it use lost wax ceramic shells.Its patterns was injection molded in advance. After pouring,it can be finished.If more perfect request, it can be made by machining and post treatment.

Precision casting also faces a cost of molding and time.For each casting producing, it requires a mold and one wax pattern. It will take more time and separated cost. So it is not good economic for low quantity products.

Precision casting has many process steps, so it will take more time for each casting. We advise you can choose precision casting if you need a lot of products.
