FAQ
What is the minimum order quantity for custom plastic injection housings?
Our minimum order quantity starts at 100 pieces for standard designs, though we can accommodate smaller quantities for complex prototypes or initial production runs. For highly customized designs, we recommend starting with at least 500 pieces to optimize cost efficiency, but we’re happy to discuss your specific requirements.
How do you ensure dimensional accuracy in plastic housing production?
We maintain dimensional accuracy through several measures: 1) Using high-precision injection molding machines with closed-loop control systems, 2) Implementing regular mold maintenance and calibration, 3) Conducting in-process inspections with coordinate measuring machines (CMM), and 4) Performing final dimensional checks on all critical features before shipment.
What certifications do your plastic injection housings have?
Our manufacturing facility is ISO9001:2015 certified, ensuring consistent quality management throughout all processes. For specific applications, we can provide materials with additional certifications including RoHS compliance, REACH compliance, UL94 flame resistance ratings, and FDA food contact approvals as required by your industry.
Can you modify existing plastic housing designs for our specific needs?
Absolutely. We specialize in design modifications to meet unique requirements. Our engineering team can analyze your existing housing design and recommend cost-effective modifications to improve functionality, reduce material costs, or enhance manufacturability while maintaining compatibility with your existing components.
What is your typical lead time for custom plastic housing production?
Lead times vary based on order complexity and quantity. For standard custom projects, our typical timeline is: 1-2 weeks for design review and tooling preparation, 2-4 weeks for sample production and approval, and 3-6 weeks for full production depending on quantity. We offer expedited services for urgent orders and maintain transparent communication throughout the process.
