Our products vary and our quest for excellence in quality never stops.

â—	A Piston Pin is a component in all kinds of engines (diesel, gasoline, 2 stroke and 4 stroke). It functions as the linkage between the piston and its gadget and bears the twist and friction incurred by the running engine.
â—	Other than the precision of the size, adequate heat treatment process and surface polishing grinding is also important. These processes enhance the wearing of the piston pins and require certain level of technical support.
