Frequently Asked Questions

Q: What are the primary benefits of powder metallurgy gears over CNC gears?

Powder metallurgy gears offer lower production costs, higher material utilization, and the ability to create self-lubricating parts, making them ideal for high-volume automotive production.

Q: Can you produce custom gear types based on my specific drawings?

Yes, we specialize in custom manufacturing. We can produce sun gears, double gears, planetary gears, helical gears, and bevel gears based on your technical blueprints.

Q: How does the lubrication-free feature work in sintered gears?

Through a process of oil impregnation, the interconnected pores of the sintered metal are filled with lubricant, which is released during operation to reduce friction.

Q: What is the typical production volume for these sintered parts?

Because we use precision pressing molds, we are optimized for mass production, typically ranging from tens of thousands to hundreds of thousands of pieces per mold set.

Q: Which automotive components are best suited for powder metallurgy?

Gearbox parts, DC motor gears, engine components, and various structural parts that require high repeatability and cost-efficiency.

Q: How does sintering affect the dimensional accuracy of the gear teeth?

Our process ensures high tooth shape accuracy during the initial molding, meeting strict dimensional requirements without the need for further reprocessing.
