Yes, small-batch trial production is supported. MOQ is evaluated by product type, process (cold heading / CNC) and material; prototyping is usually not limited by volume. Send us your drawings and annual usage to discuss.
Standard samples in as fast as 1 day, usually within 1 week; mold-making or special surface treatment adds lead time. Prototype cost and whether it can be credited against bulk orders is evaluated per project, subject to quotation.
We are IATF16949 certified with 26 valid patents. Material certificates, full-dimension inspection reports, salt-spray and torque test reports can be provided per project, with PPAP documentation support.
After mold completion, cold-headed parts ship in 2-4 weeks; small CNC parts in about 1-2 weeks. Actual lead time depends on quantity, material stock and surface treatment, confirmed at order placement.
Drawing/sample confirmation → process & cost evaluation → prototype validation → sample approval → mass production & delivery. Our engineers work with you throughout, supporting co-development.
Drawings (or physical samples), material and property grade, surface treatment, annual usage and lead-time expectations. The more complete the information, the more accurate the quote and process advice.
