We has more than 30 numerical controls engine beds, Metal material physics and chemistry experiment, cloth chromium Uygur machine for testing hardness heat treatment quenching and tempering and so on advanced processing and check-out facility. At present may process the pitch is the 1~16mm valve lever thread light pole spot uses hammers the cold-press to take shape the new technology, Causes the product superficially attractive fineness to achieve the mirror surface the effect, The concentricity is good, Wear-resisting, High strength, Causes the valve to open shuts with ease, The life is long.
