Industries Served

Automotive
Valve Timing Control
Valve Timing Control
Used in an internal combustion engine, Variable Valve Timing (VVT) systems altering the timing of a valve lift cycle, resulting in improved performance, fuel economy or emissions.
Sprockets & Pulleys
Sprockets & Pulleys
Whether driving a timing system, oil pump system, or water pump system, HPM can provide a robust low cost sprocket or pulley. HPM supplies many different sprockets and pulleys working with various types of chains and belts. HPM’s expertise can help design the right part at the right cost for any automotive sprocket or pulley application.
Valve Guide
Valve Guide
HPM valve guide materials are designed to stand up to today's toughest engine environments. Whether it is high exhaust gas temperatures, little to no lubricity fuels, or valvetrain side loading. HPM has a material that can work in any application while still providing good machinability for finish reaming.
Bearing Caps
Bearing Caps
Bearing caps are used to mount the crankshaft to the engine block or the camshaft to the head. HPM’s materials and processing allow for good strength and dimensional control. HPM has highly automated production lines that can produce high volume bearing caps across the globe.
Turbocharger Parts
Turbocharger Parts
Nozzle Ring
Bushing
Roller
Pin
Turbochargers use exhaust gas to drive a turbine. This spins an air compressor that pushes extra air (and oxygen) into the cylinders, allowing them to burn more fuel boosting an engines power output.
Transmission Parts
Transmission Parts
Synchronizer Hubs - The synchronizer hub (primary product for the shifting operation) is fixed on the output shaft of a manual transmission.
Synchronizer Rings - A synchronizer ring sits between the synchronizer and each gear to synchronize the speed of the sleeve and gear.
Carriers (AT/CVT) - Carries house a gear set which is the mechanical systems that provide the various forward gear ratios as well as reverse position.
Lawn & Garden
Cylinder Blocks
Cylinder Blocks
Cylinder Blocks house the pistons (and pump shaft) which slide against a swash plate determining the output of the oil flow.
Swash Plate
Swash Plate
Swash Plates (in Hydrostatic Transmissions) are used for varying the displacement within the of the pump from zero to maximum fluid output dependent upon the angle of the plate.
Valve Guides

HPM valve guide materials are designed to stand up to today's toughest engine environments. Whether it is high exhaust gas temperatures, little to no lubricity fuels, or valvetrain side loading. HPM has a material that can work in any application while still providing good machinability for finish reaming.

Primary Driven Gear
Primary Driven Gear
Transfers power from the crankshaft to the clutch system.
Oil Pump Rotors
Oil Pump Rotors
Rotors are used to displace oil in the oil pump and push it into the oil galleys so it can flow to the bearings and upper valvetrain. What actually creates the oil pressure is the resistance the oil encounters as it circulates through the engine.
