Near-net-shape powder metal gears engineered for consistent dimensional accuracy, mechanical strength, and long service life — supplied from prototype to full mass production.
Sintered gears are manufactured through powder metallurgy — a process where metal powder is compacted into a gear-shaped die under high pressure and then sintered in a controlled atmosphere furnace. The result is a near-net-shape gear with consistent geometry, minimal material waste, and excellent repeatability.
At Wisma Technology, we source and supply precision sintered gears through our established network of qualified manufacturing partners. Every component undergoes strict dimensional verification to ensure it meets your engineering drawings and application requirements before delivery.
From initial design review and feasibility assessment through to prototype sampling and certified mass production, we manage the full supply chain on your behalf — giving you one reliable partner from first sketch to ongoing production supply.
The powder metallurgy process produces gears close to final dimensions, minimising the need for machining and reducing overall production cost.
Die-compaction ensures every gear produced from the same tooling is dimensionally consistent — critical for high-volume production runs.
Low per-unit cost at mass production quantities, with minimal scrap and efficient material utilisation compared to machined alternatives.
Powder metallurgy allows for integrated features such as keyways, holes, and stepped profiles to be compacted directly into the part.
All gear types are available to your exact drawing specifications and tolerance requirements.
The most common sintered gear type, featuring straight teeth parallel to the gear axis. Ideal for applications requiring efficient power transmission between parallel shafts at moderate speeds.
Teeth are cut at an angle to the gear axis, enabling smoother and quieter meshing than spur gears. Preferred in automotive and household appliance applications where noise reduction is critical.
Designed to transmit motion between intersecting shafts, typically at 90 degrees. Commonly used in differential drives, power tools, and actuator systems requiring direction change.
Material selection is based on your application requirements — we advise on the best option during feasibility review.
The most widely used material family for sintered gears, offering an excellent balance of mechanical strength, dimensional control, and cost efficiency. Composition — including carbon, copper, and alloying element content — is tailored to your load, torque, and wear requirements. Suitable for the majority of automotive, household appliance, and industrial gear applications.
Selected for applications requiring corrosion resistance or operation in wet, humid, or chemically exposed environments. Sintered stainless steel gears offer good mechanical properties with the added benefit of oxidation resistance, making them suitable for food-adjacent, medical-adjacent, and outdoor industrial applications.
Our sintered gears are used across demanding applications in multiple sectors worldwide.
Power window motors, windshield wipers, seat adjusters, HVAC actuators, and electric power steering systems.
Washing machine drive systems, vacuum cleaner motors, stand mixers, air conditioning units, and robotic cleaners.
Actuators, gear reducers, conveyor drives, and precision motion control systems requiring consistent long-term performance.
Drills, sanders, grinders, and electric screwdrivers where compact, high-strength gear sets are required for reliable torque transmission.
