Introduction of precision casting (Metal Casting)

 

 

What is precision casting?

 

 

casting
 
 

Precision casting method refers to the use of non-metallic mold (shell mold), accuracy dimension and the bright surface is higher than the general sand casting method which has a unique characteristic and advantages different from general traditional casting, forging, and mechanical cutting.

 

Precision casting is divided into several categories, including lost-wax casting, die-casting, gravity casting and sand casting, etc. We’ll elaborate on these kinds of methods and also introduce the advantages and the applications.

 

What is the advantage of precision casting?

 

 

  • Can produce parts with arbitrarily complex shapes, especially those with complex internal cavity shapes
  • Adaptability, unlimited alloy types, almost unlimited casting size
  • Wide source of materials, remeltable waste, low equipment investment
  • High scrap rate, low surface quality and poor working conditions

The metal type has high manufacturing cost, long cycle and strict process requirements. It is not suitable for the production of single-piece small batch castings. It is mainly suitable for mass production of non-ferrous alloy castings, such as aluminum pistons for airplanes, automobiles, internal combustion engines, motorcycles, etc. , cylinder block, cylinder head, oil pump casing and copper alloy bushings, bushings, etc. For black alloy castings, it is also limited to medium and small castings with simple shapes.
