Silica Sol Investment Casting

Investment casting process always classified in 2 types, one we called is an American style Silica Sol casting process with green wax (median-temperature wax) and better sands, it makes casting parts with smooth surface, tight tolerance, normally it’s suitable for small part making and widely used in stainless steel material, also carbon steel and alloy steel etc.

Silica sol casting process is worked in a special designed workshop, with strict material, Temp. & processes controlling, it offers the best quality castings in surface finishing, tolerance and in purity of alloy grade, it is also the most expensive of all casting processes. Stainless steel investment castings ( widely used material: ASTM 304SS and ASTM 316SS ) are primarily used for corrosion resistance, abrasion resistance and they typically do not require any plating and additional machining operations, this allows the customers to have very little waste of raw material and reducing overall costs

CNC metal machining

We are specialized in manufacturing of high precision, complex machined components, as well as prototype and medium volume production works.

We produce not only blank casting parts, but also provide machining processing service for all castings with complete assembly to customers if it is requested:

Metal turning, milling, drilling, thread taping, grinding and all other high-precise CNC machining operations and it covers material of stainless steel casting machining, steel casting machining, aluminum alloy casting machining, forging parts machining & stock bar material machining etc.

With our complete quality control system and advanced equipment, we can making machining parts in closed tolerance and high grade surface quality!

Lost Wax Casting

Lost-wax casting (also called "investment casting", "precision casting" which is one kind of investment casting process, by using white-wax pattern to meet different casting structure requirements.

It builds a mold around a sacrificial wax model, after the mold investment is set, the wax is melted out and forms a cavity where the metals flows in & gets the fine details of casting parts. this process is used to create parts for Transportation, Agricultural, Automobile, railway , construction and Mining machinery industries etc,. It can be used to create objects from simple to complex in various metal material in stainless steel, alloy steel and carbon steel according to customer requestes.

We handle each job with an optimal process to achieve the lowest cost, best quality, and highest efficiency.
