Investment 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 which are different from general Precision Machining,Stamping andForging.

Investment castinghas several categories, including lost-wax casting, die-casting, gravity casting,sand casting and so on. We’ll elaborate on these kinds of methods and also introduce the advantages and the applications.


What is the advantage ofInvestment Casting?


Adaptability, unlimited alloy types, almost unlimited casting size

Can produce parts with arbitrarily complex shapes, especially those with complex internal cavity shapes

Wide source of materials, low equipment investment

High scrap rate, low surface quality and poor working conditions

What is the process ofInvestment casting?

 What is the application ofInvestment casting?

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 mainlyused for mass production of non-ferrous alloy castings, such as door handle, door escutcheon, door lock cylinder,door lock body, doorlockaccessories,door lock pivot,door latch bolt,door strike plate,etc. For black alloy castings, it is also limited to medium and small castings with simple shapes.
