Cylinder Blocks

Cylinder blocks, in which iron casting liners have been installed through insert casting, are cast using High Pressure Die Casting (HPDC) method. With our continuous production approach from casting to machining utilizing flexible machining lines, we manufacture high-quality products at lower costs.

Oil Pans

Oil pans are one of thin-walled parts with complicated forms. Under our continuous production approach from casting to machining, the oil route area is cast using high molding pressure and machined on flexible machining lines. We also manufacture oil pans with built-in oil pumps.

Water Outlets

Water outlets are casting parts with multidirectional draft direction, including diagonal one. To meet strict pore standards and withstanding pressure requirements of machining surface, we adopt Pore-Free (PF) method.
