The professional foundry base and machining center occupies about 10,000 square meters. The flexible production line adopts advanced CNC machines and other special machine for critical operation. They can finish rough and fine milling, boring and drilling of the cylinder head critical area in high efficiency and stability. All those equipment are of world famous brand which can reduce failure rate of the operators.

The installation of critical accessories such as valve seat, valve guide and camshaft bearing are carried out by automatic equipment. All parts will go through liquid nitrogen treatment before installation. Because of contraction principle, those parts can be easily mounted on the cylinder head, avoiding the damage caused by installation and increasing the mechanical property.
