Powertrain Components

TPR is a global leader in piston ring design and production

TPR offers a multitude of geometries and surface treatments to best suit your application.

Surface treatments include DLC, PVD, Chrome and more

Proprietary AB-1 oil ring shape provides optimal LOC for automotive engines

Global leader in cylinder liner production cover cast-in-block, dry and wet liners.

Innovators of AsLock spiny liner technology for best performance aluminum block engines through improved adhesion.

Capable of super low ID roughness (1μmRz) leading to lower LOC (lube-oil consumption) as well as various surface treatment options for heavy duty liners such as Phosphate, Nitride, Chrome, and others.

Scrapes off hard card carbon that has adhered to the piston top land.

Prevents liner inner wall friction, and stabilizes the low position of lubricating oil consumption.

Using the same material as the Cylinder Liner assures same heat expansion.

Various types of compound rubber O rings for hydraulic/pneumatic, 4-wheel, 2-wheel, construction equipment, agricultural equipment, general industrial machinery, cosmetics, medical ancillary equipment, etc.

Rubber products such as gaskets and seals required for specialist technologies

Our major sintered products include valve seats and valve guides. 

They provide base and stem support for the engine intake and exhaust valves, respectively, and must be highly durable and precise. 

It is important to select powder metallurgical materials that are highly resistant to wear and heat.
