Carbon steel investment castings for mechanical components in various industries like medical, marine, electronics,train, Military, Aerospace, construction etc;

We perform steel lost wax casting process in a wide range of alloys, please refer to below table for the most common material that Winnington cast:

Overview of Lost Wax Method

The model of the part is made of wax from an aluminum die, then the wax patterns are welded onto the runner system which is also made of wax - it forms a pattern tree or called pattern assembly. Next, the pattern tree will be dipped into ceramic slurry of sand or stucco, with drying process between each coating until the shell is thick enough to hold the weight of melten metal which will be poured later. 

Then the Pattern tree with wax in it is going to a high pressure oven which melt the wax out. It forms a hollow in the shell. The shell is preheated before pouring to help fluidity of melton metal. A sand bed is always aside to hold the hot poured shell. 

In the following process, the shell is broken and removed, so the castings can be seen now. The castings are then cut off from the metal tree and shot blast/polished/machined to get better tolerance and surface.

Competitive Advantage:

Investment Casting is generally more expensive than it's associated metal casting methods of "die casting" or "sand casting", but can produce complicated shapes that require little machining and at good surface quality. Investment casting is used in many advanced technical industries such as Aerospace, Power Generation, Oil & Gas, Military & Defense, Medical, Commercial and Automotive.
