MIM Gear
NOWARUN produces small module gears using metal injection moulding technology from stainless steel, iron-based steel, and various alloy-based steels. Manufactured strictly to customer drawings rather than sold from a catalogue, these MIM gears provide net-shape complex tooth geometry for applications across diverse industries. The process suits production where conventional gear cutting or multi-axis machining of intricate small module profiles becomes cost-prohibitive.

How It Is Made
- 1
Customer drawing review and mould design tailored to the small module gear geometry
- 2
Feedstock compounding combining metal powder with polymer binder systems
- 3
Injection moulding to produce the green gear body with accurate profile features
- 4
Debinding process to remove the primary binder system from the moulded component
- 5
High-temperature sintering to achieve final density and target mechanical properties
- 6
Packaging in PP bags, cartons, crates, or boxes per customer requirements
Quality Control
- Dimensional verification of tooth profile and bore against the customer engineering print
- Sintered density and material composition checks against alloy requirements
- Visual inspection for surface integrity, flash, or moulding irregularities
- Standard export packaging verification to protect tooth edges during transport
Customization Options
- Tooling fabricated to specific tooth counts, pressure angles, and small module profiles
- Bore shapes, keyways, and integrated pinion steps built to your drawing
- Material selection tailored across stainless, iron-based, or alloy-based formulations
- Packaging arranged in PP bags, cartons, crates, or custom box configurations
Compared With the Alternatives
| Alternative | Honest trade off |
|---|---|
| Hobbed or milled small gears | MIM lowers per-part unit cost on complex geometries in volume, but requires dedicated tooling upfront |
| Standard catalogue small gears | MIM delivers your exact hub and tooth geometry to print, but requires drawing approval and tooling lead time |
| Plastic injection moulded gears | MIM steel components handle significantly higher torque and wear, but involve higher material and sintering costs |
Use Guide
- Provide complete 2D and 3D engineering drawings showing tooth profile, module, and tolerances
- Specify your target material between stainless steel, iron-based steel, or alloy-based steel
- Review the sintered component drawing and shrinkage allowances during mould design approval
- Confirm packaging preferences such as PP bags or boxed lots prior to shipment
