Sintered Gears

Sintered Gears - precision sintered gears by Huaxiao, ISO 9001:2015 certified metal manufacturing

Sintered gears form teeth directly in the die, avoiding machining and cutting cost dramatically at high volume. Huaxiao delivers sintered gears as part of our ISO 9001:2015 certified Powder Metallurgy capabilities — from rapid prototyping to high-volume production, with full dimensional inspection and material certification on every order.

What Is Sintered Gears?

Sintered Gears is a specialized capability within our Powder Metallurgy service. Sintered gears form teeth directly in the die, avoiding machining and cutting cost dramatically at high volume. It is chosen when parts demand the specific combination of geometry, tolerance, material and volume that this process delivers best. Our engineers select and fine-tune the exact parameters for your application to balance performance, lead time and cost.

Frequently Asked Questions

Q: How does PM compare to CNC in cost?
A: Above 5,000 pieces/year, PM typically cuts cost 30-70% versus CNC machining.
Q: What are the limitations?
A: Best under 150mm diameter and 10kg; thin walls under 1.5mm can be challenging.
Q: Can PM parts be heat treated?
A: Yes — quench, case-harden or steam-treat to HRC 45.
