Quality Control
Every Assembly Tested.
Every Batch Documented.
Quality is not inspected at the end of production — it is built into every stage. Our inspection protocol covers six distinct checkpoints, generating traceable records from the first component receipt to the final shipment.
Incoming Material Inspection
All raw materials — wire, connectors, terminals, and insulation — are inspected and verified against approved material specifications before entering production. Non-conforming materials are quarantined and returned.
Crimp Pull Test
Termination integrity is validated through pull-force testing against IPC/WHMA-A-620 requirements. Crimp height measurements are recorded for every press setup, ensuring connection reliability under mechanical stress.
Continuity & Hi-Pot Test
100% of completed assemblies undergo electrical continuity testing and high-potential (hi-pot) dielectric withstand testing. Every circuit is verified; no units ship with untested connections.
Waterproof Integrity Test
Sealed assemblies are subject to IP67/IP68 immersion testing. Pressure and submersion protocols confirm that the sealing system performs to specification under real operating conditions — not just catalogue ratings.
Aging & Environmental Test
Selected products undergo accelerated aging, thermal cycling, and UV exposure testing to validate long-term performance. Testing reports are available for customer review upon request.
Final Inspection & Shipment Release
A trained QC inspector performs visual and dimensional checks on every outgoing batch. Shipments are released with complete traceability documentation, test reports, and applicable compliance certificates.

Client Feedback
What Procurement Teams
Say After Working With Us
Long-term sourcing relationships are built on consistent delivery and technical reliability. These are buyers who have tested that consistency across multiple orders and projects.
We evaluated three Chinese cable suppliers before choosing Chnkbl. The prototyping turnaround was faster than anything we had seen at this price level, and the sample quality matched production — which is rare. We have been ordering for two years with zero quality escalations.
Our EV charger program required IATF-compliant harness assemblies with rapid iteration on connector specs. Chnkbl's engineering team caught a routing issue before tooling was committed — that saved us significant development cost and delay. Highly recommended for serious EV programs.
As a medical device manufacturer, our supplier requirements are stringent. ISO 13485 certification, full material traceability, and reliable documentation are non-negotiable. Chnkbl meets all three consistently and the communication turnaround is genuinely exceptional.
Reference customers are available upon request for qualified procurement teams conducting supplier due diligence.

Industry Insight
Why Sample-to-Production Consistency Is the Most Important Metric in Harness Sourcing
The most common cause of supplier switches in cable assembly is not price — it is the gap between approved sample quality and production batch quality. Here is how to test for it early.

Questions Procurement Managers
Ask Before the First Order
Straight answers to the sourcing questions that matter. If you have a question not covered here, our engineering team responds within 24 hours.
We actively support low-MOQ projects and new product launches. Typical MOQ varies by product complexity, but we routinely work with quantities from 50 to a few hundred pieces for custom assemblies. Contact us with your specification and we will confirm feasibility.
Standard prototype lead time is 7–14 business days from drawing approval, depending on component availability and assembly complexity. Expedited timelines are available for urgent development programs — discuss your schedule with our engineering team.
We hold ISO 9001, IATF 16949, and ISO 13485 quality management certifications. Products are manufactured in compliance with UL, RoHS, and REACH requirements. Copies of all certificates are available on request along with declarations of conformity for specific product categories.
Yes. We provide full OEM services for customers supplying drawings and specifications, and ODM services where our engineering team develops assemblies based on your application requirements. NDA agreements are standard for new design projects.
Samples are a standard part of our qualification process. We produce engineering samples for customer approval before any production run is confirmed. Sample charges are typically credited against first production orders above a minimum quantity.
We ship to 35+ countries via express (DHL/FedEx/UPS), sea freight, and air freight. Standard production lead times run 15–30 business days after sample approval. We provide full export documentation, commercial invoices, packing lists, and certificates of origin as required.
