Precision Investment Casting

The use of silicone shell precision casting, precision machining, surface treatment and other advanced technology, production and operation of stainless steel, heat-resistant steel, carbon steel, low-alloy steel, high-temperature alloys, non-ferrous alloys and other materials of various kinds of high-precision castings and deep processing products.

Potential for rapid production

It has laser powder sintering rapid molding machine, optical curing rapid molding machine, which can be used for rapid sampling and rapid production of small batches of products.

Vacuum casting facilities

Has vacuum melting furnaces that can produce nickel and cobalt based alloys and single weight products in the range: 0001 - 25Kg.

Able to produce complex products.

Possesses advanced casting simulation software to help process design of product process, can use soluble cores, ceramic cores, salt cores, molding sand C - 1 and other special processes to achieve complex product development design.
