FAQ
What is the minimum order quantity for custom socket OEM services?
We accept both small batch prototype orders and large volume production. The minimum order quantity depends on the complexity of the product, typically starting from 500-1,000 pieces for simple components and 1,000-5,000 pieces for more complex assemblies. We also offer sample production services for design verification before mass production.
How long does it take to produce custom sockets?
Production lead time varies based on order quantity and product complexity. For sample orders, we typically require 7-15 working days after design approval. Mass production lead times range from 15-30 working days for quantities up to 100,000 pieces. We maintain flexible production scheduling to accommodate urgent orders when possible.
What file formats do you accept for custom designs?
We accept various design file formats including 2D drawings (PDF, DWG, DXF) and 3D models (STEP, IGES, SLDPRT). For complex products, we recommend providing detailed 3D models along with 2D dimensioned drawings. Our engineering team can also work from physical samples when digital designs are not available.
Can you help with product design optimization?
Yes, our experienced engineering team provides DFM (Design for Manufacturing) services to help optimize product designs for cost-effective production. We analyze designs for manufacturability, suggest material alternatives, and recommend process improvements to reduce production costs while maintaining functionality.
