Design Tips: Powder Metallurgy Gears

1. The radius should be greater than 0.25 mm for manufacturing the die.
2. Helical teeth should have a helical angle less than 30º to limit side pressure on the punches.
3. Introducing a draft angle greater than 5º in the upper diameter can reduce tooling cost.
4. The distance between the tooth root and central hub diameter must be greater than 3 mm for robust tooling.
