We've been running these through our CNC shop for years, and teh ±0.01mm tolerance is what actually matters when you're mating connectors in high-vibration environment like automotive power distribution — slop there gets you intermittent faults that are a nightmare to trace down. Most buyers go with brass for conductivity unless they need the corrosion resistnce of stainless steel, but plastic bodies are pretty much only for low-current signal applications where you're chasing weight savings.
Cold stamping is faster for high-volume runs, but we'll CNC machine anything that needs tighter tolerances or has weird geometry that won't stamp cleanly — those custom ODM jobs with non-standard pin spacing usually land here. Surface treatment options are electroplating, spraying, polishing, or oxidation, and honestly the electroplating is better than spraying for maintaining consistent contact resistance over temperature cycles. Sample lead time is 5-7 working days, though we usually have stock on common brass blanks if you're in a hurry.
ISO 9001 covers quality system, but we also run CE and CCC certifications for export — CCC is mandatory if these are going into Chinese-built machinery, so check your destination before ordering. Each batch gets a COA with dimnesions and surface finish readings, usually within 2-3 days of shipment. We don't do MOQ on samples, but production orders typically start at 500 units or so for custom tooling setups.
One thing buyers don't always think to ask is the thread lock on screw terminals — our company can apply a micro-encapsulated threadlocker at no extra cost if you specify it, otherwise you'll need to add your own for applications over 80°C ambient. Also, the plastic options are limited to about 120°C continuous service, so don't spec them for engine bay connectors without checking the thermal profile first. For power systems application, stick with brass or stainless and specify the electroplating thickness (usually 5-10 microns) to avoid galling during installation.
Anyway, what it does is take your connector drawing and turn it into a functional part at ±0.01mm, with surface finish options that match your enclosure specs — we've done matte black oxidation for construction equipment and bright nickel for panel-mount power connectors. Cold stamping is better than CNC machining for simple geometries if volume is above 10,000 units, but the tooling lead time adds about 3-4 weeks to the first run. We confirm lead time on each quote since capasity fluctuates with the machining schedule.
We don't have a fixed MOQ — we can handle small prototype runs or full production volumes. Just tell us your quantity and we'll work out the pricing.
That's our standard precision for CNC machining, holding within 0.01mm of your specs. For most automotive or power system applications, that's more than enough.
Yes, we can supply mill test reports for raw materials upon request. We're ISO 9001 certified, so quality docs are part of our process.
Absolutely — we offer electroplating, spraying, polishing, and oxidation. Just send us your color code or finish preference, and we'll match it.
Samples usually take 5-7 working days from design approval. For production orders, lead time depends on volume but we'll give you a clear timeline upfront.
