Powertrain Components

Custom Impression Die Forging (Process)

We offer solutions in manufacturing crankshafts from design to forging and inspection services based on our customers' needs. Our crankshaft manufacturing processes are clearly defined prior to production, ensuring high quality of the end product.

A crankshaft manufactured by the forging process typically imparts greater strength and density as compared to a casting or crankshaft machined from bar. We design and tailor our crankshaft forging process to each application.

Typical Powertrain Components: Crankshafts, Connecting Rods  & Camshafts

  • Inline Crankshaft
