Investment Casting Process

 

NO:1 Metal Die Casting
Based on the drawings and requirements of the desired cast part,the metal die or mold,usually in aluminum, will be design and produced.The cavity will form the same sized and structure of desired cast part.

NO:2 Wax Injection
Also as known as pattern formation,Lost wax casting patterns are created by injecting molten wax into the metal die above.  
 

NO:3 Slurry Assembly
The wax patterns are then attached to a gating system,which usually is a set of channels through which a molten metal flsows to the mold cavity.After that,a structure like a tree is formed,which is suitable for mass production.
 

NO:4 Shell Building
The investment casting outer shell casing is built up through dipping into a ceramic bath and then immediately coated with sand for several times.
 

NO:5 De-waxing
The inner cavity of precision investment casting is then dewaxed,which leaves a hollow outer ceramic shell layer.The hollows are just the same space as the desired castings.
 

NO:6 Pre-Pouring Analysis
Pre-pouring analysis means that the foundry need to check and analyse the chemical composition of the molten metal to see if they are meet the require numbers or the stardard.some times,this analysis would be made several times.

NO:7 Pouring & Solidification
The ceramic shell with cavity should be pre-heated before pouring.This prevents shock and the ceramic shell from cracking once the liquid metal at a high temperature is poured into the cavity.
 

NO:8 Sawing or Cutting
Once the metal has cooled and solidified,the cast part is then removed from the gating system tree cluster via shaking,cutting or friction sawing off the individual cast part.
 

NO:9
Shot Blasting and Secondary Processing
The casting part is then fully customized through grinding or additional heat treatments.Secondary machining or surface treatment might also be required depending on the requirements or the part.
 

NO:10 Packing and Delivery
Then the lost wax casting part will be fully tested for the    dimensions,surface,mechanical properties and other required tests before packing and delivery.
