When you're sourcing gear components for a production line that can't afford downtime, tolerances matter — I've seen what happens when a batch of parts comes in at ±0.02mm instead of ±0.01mm, and it's never pretty.
Most buyers start asking about material options pretty early, so just so you know — we run brass, alumnum, stainlss steel, and carbon steel, and precision grade holds at ±0.01mm regardless of which you choose. Suface finish can be as machined, polished, or anodized, and is optional for carbon steel especially (usually adds about 5-7 days to lead time). We follow JIS, ANSI, or DIN standard depending on your spec, and every single piece goes through 100% dimensional inspection — which is tighter than a lot of shops I've dealt with. The actual MOQ for custom designs is 100 pieces, though if you're ordering a standerd item (one of our off-the-shelf ones), our company can ship free samples first.
Some buyers use these in power tools, others in indutrial machinery or automotive assemblies — basically any application where consistent meshing and load distribution matters. One thing I'll be straight about though: with cold forming, you get durable blanks but the thread depth tolerance can shift slightly if the tooling warms up during high-volume runs, so it's not ideal for aerospace-grade clockwork or something needing sub-0.005mm repeatability on every tooth face. That's just a reality of the method — not a problem for 95% of what we do, but you should know.
Lead time runs 15-30 days for production, and we usually have about 300kg-500kg of common brass and steel blanks in stock at any given time. Payment terms are generally T/T or L/C at sight, our company provide COA with every batch, and packing is anti-rust paper plus carton boxes — we've shipped thousands of units this way without complaint. Give or take, the whole order process takes roughly 4-6 weeks from sample approval to delivery.
For custom designs, lead time is 15-30 days after order confirmation. If you need a rush, we can sometimes push it to 10-12 days depending on current capacity. Just let us know your deadline.
Yes, we include RoHS and CE certificates with every order. For material certifications like mill test reports, just request them when placing the order — we'll include them at no extra charge.
For custom designs, our minimum order is 100 pieces. If you need fewer for prototyping, we can offer free samples or a small-batch run — just get in touch.
We use anti-rust packaging for all metal parts — VCI paper or oil coating, depending on the material. Then they go in sturdy carton boxes. For stainless steel, we skip the oil but still protect against scratches.
We don't have strict size limits, but for high precision (±0.01mm) we recommend keeping part dimensions under 300mm. Complex geometries like helical or bevel gears are fine — just share your CAD file and we'll confirm feasibility.
