A review meeting is held within the technical department to review the specific details, determine the gating system and verify it through the simulation system software MAGMA.

The technical department develops the mould, and the quality department uses the coordinate measuring machine to carry out the dimensional inspection.

All metal materials are 100% inspected by the QA team. Unqualified materials are strictly prohibited from entering the warehouse.

There is currently one wax pattern shift. The workshop uses an automatic waxing machine to set the waxing pressure, holding time, and etc.

The workshop has 4 automatic production lines and can produce 1800 sets of shells. We use hygrothermograph, aerometer and PH monitor for monitoring the humiture and the concentration of liquor aluminum chloride.

Four 500KG furnaces cast at the same time, and three additional 500KG furnaces are ready for use when capacity increases. The operators measure the temperature of the molten steel.

The workshop is fully equipped with 8 heat treatment furnaces, 3 quenching furnaces, 1 central shot blasting machine and 11 large shot blasting machines.

The technical department develops workshop control plans and product operations guide book, and there are specialists who check each parameter on a daily basis. The target is inspected and kept on record.

All blanks' dimensions are checked by using CMMs. We have a wide range of equipments for inspections. The company's quality department has certified employees to do UT, PT, and MT testing.
