Custom iron-based, copper-based and stainless-steel powder metallurgy structural parts, high-precision oil-impregnated bearings, and precision micro gears. Trusted across automotive, smart home, power tools, IT, office equipment and 3C applications.
From powder compaction and sintering to sizing and secondary machining — each step is engineered around your part drawing.
Powder metallurgy is a manufacturing process in which metal powder is compacted into a shaped die and then sintered under controlled conditions to bond the particles. The process produces near-net-shape parts efficiently for high-volume production.

Powder compaction presses metal powder in a shaped die into a green compact. It is the shaping step in powder metallurgy and determines part geometry, density and many final properties.
View capability →Sintering heats a powder compact to just below its melting point so that particles bond through diffusion, giving the part strength and structural integrity. It is the key step that turns a pressed powder part into a usable component.
View capability →Sizing is a secondary pressing of a sintered part inside a sizing die to improve dimensional accuracy and surface finish. It is used when pressed-and-sintered tolerances are not tight enough for the application.
View capability →Secondary CNC machining is applied to powder metallurgy parts for features that cannot be produced net-shape in the die, such as cross holes, tight tolerances and undercuts. Combining PM near-net-shape with targeted machining can reduce overall cost.

Custom tooling is the shaped die set used to press a specific powder metallurgy part. Die design requires a full review of the part drawing so the final geometry, density and dimensions are achievable before the tool is built.
View capability →Precision micro gears, oil-impregnated bearings and high-strength structural parts — all produced from custom tooling and customer drawings.
Sintered gears are powder metallurgy components pressed and sintered to near-net shape. The process suits high-volume production of repeatable gear geometries in iron-, copper- and stainless-steel-based powders, for automotive, power tool, office equipment and smart home drive trains.
View details →Sintered bushings and oil-impregnated bearings are pressed from metal powder and sintered with a controlled porous structure that can hold lubricating oil. They provide a self-lubricating, cost-efficient bearing solution for high-volume rotating and sliding applications.
View details →Structural powder metallurgy parts are high-strength components pressed and sintered to near-net shape. They include housings, brackets, levers, chassis structures and lock mechanisms produced in volume with consistent dimensions.

Powder metallurgy produces repeatable, high-volume automotive components such as sensor housings, brake and ABS parts, seat belt mechanisms, hydraulic valve spools and powertrain parts, with efficient material use and tight dimensional consistency.
Smart-home devices require dependable moving and structural parts. Powder metallurgy supports internal components for smart locks, brackets and holders for lamps, curtain controller structural parts and small transmission gears.
Power-tool transmissions need strong, wear-resistant gear components. Powder metallurgy suits the high-volume production of general, planetary and bevel gears plus structural parts used in drills, grinders and garden tools.
IT and telecom devices use PM parts for connector contacts, EMI shields and lightweight structural chassis components. The process produces repeatable small parts with good material properties.
Office equipment relies on long-service mechanical parts. PM supplies high-precision wear-resistant printer gears, copier drive-shaft parts, scanner brackets and other structural components.
3C digital products use small precision PM parts such as camera gear components, headphone bracket structures, controller buttons and charger bracket structures, where high precision and durable performance matter.
