Core FAQ Questions & Details：
How does your factory control quality?
We are an ISO 9001, IATF 16949, and UL certified manufacturer with a comprehensive quality control system. Our 50+ quality staffs implement CKP, PFMEA to monitor our production process:
IQC (AQL=0.65) → IPQC → 100% Testing/X-Ray Inspection → 100% FQC → 1st OQC (AQL=0.65) → 2nd OQC (AQL=0.65).
Additionally, we conduct hourly terminal pull tests, and all crimped terminals undergo 100% magnification inspection prior to assembly.
Is there any environmental risk on materials?
we are an ISO9001/IATF16949 certified company, and all materials comply with RoHS and REACH standards. We source components from established long-term partners, and our products have been exported to Europe and North America for 25+ years. For added assurance, we can provide a COC upon request.
How to customize your products?
If you have technical drawings please send them to us. Or please send us photos or samples instead if no drawings, along with your specifications and details. Pls include wire gauge, length and wiring diagram; connector/terminal P/N or types; shield covering materials; any other special requirements. We can assist in creating the technical drawing and provide it for your approval.
Can you provide OEM & ODM service?
Yes. With over 25 years of expertise in manufacturing high-quality wire harnesses and molded Cable Assemblies, we proudly offer comprehensive OEM and ODM solutions. Our professional engineering team is dedicated to supporting custom projects. We deliver turnkey solutions for fully integrated products, encompassing: Wire harness assembly, Plastic enclosures, Terminals and Connectors, Tooling design and fabrication, PCBA assembly, Silicone components and metal stamping parts,etc. Our one-stop approach ensures seamless project execution from concept to production, tailored to your specific needs.
Can you provide samples for testing?
Yes, sample provision for testing is available. After price confirmation, we can arrange samples to validate performance. While most samples are provided free of charge (subject to type and quantity), please note that shipping costs are typically the responsibility of the recipient.
What is your lead time for mass production?
Our mass production lead time is contingent upon order quantity and product complexity. For standard projects, the typical lead time ranges from 2 to 6 weeks. For specialized customized products—especially those with intricate designs or requiring raw materials with extended procurement cycles—the lead time may extend to 8-20 weeks.
Upon confirmation of the business partnership and annual demand, we proactively collaborate to develop flexible solutions for mitigating long lead times, ensuring optimal project timelines.
Do your products come with any warranties?
Yes, all our products are engineered for long-term durability across industrial applications. Specifically, wire harnesses are covered by a standard 1-year warranty, which safeguards against manufacturing defects and material flaws.
Even beyond the warranty period, we remain committed to supporting our customers. For any quality-related concerns arising after the warranty expires, we will work collaboratively to assess and resolve issues, ensuring ongoing reliability of our products.
Do your support low-volume/high-mix orders?
Yes, we specialize in flexible manufacturing solutions to accommodate low-volume /high-mix production requirements. Our mass production approach is tailored to raw material availability and product complexity:
For standard products:Typical MOQ: 50-500 pieces, suitable for low-volume orders.
For specialized custom products:For items with complex designs or requiring raw materials with high supplier MOQs (e.g., specialized components), the MOQ may range from 1,000-5,000 pieces or higher.
Flexible Solutions for High MOQs: Upon confirming annual demand, we collaborate with customers to implement strategies for mitigating high MOQs, including: Substituting materials with standard local or in-stock alternatives; Procuring excess raw materials to maintain inventory as customer-supplied components for future orders; Customer supply the custom parts to us for assembly.
Can you accommodate rush orders and expedite lead times?
Yes, we specialize in handling rush orders and have established processes to ensure tight lead times for urgent projects. So we can offer rush order services with:
~Dedicated production lines for urgent projects
~Flexible supply chain to prioritize material procurement
~Typical lead time reduction: 50% for standard products
~Surcharges apply based on order urgency.
