4

QC & Packaging

100% continuity testing, appearance inspection, and secure export packaging.

Quality Inspection & Continuity Checking

As a reliable wire harness supplier, we enforce strict quality control protocols. Every custom wire harness undergoes rigorous testing to ensure it meets precise electrical and mechanical standards before leaving the facility.

100% Continuity Testing

Comprehensive electrical testing to verify point-to-point connections, detect shorts, and ensure proper routing.

Appearance Inspection

Visual checks for proper crimping alignment, insertion depth, label placement, and overall assembly integrity.

Pull Testing

Random sampling to ensure terminal crimp strength meets industrial application requirements.

Frequently Asked Questions

Common inquiries regarding our cable assembly, wire harness, and electronic connector services.

What types of files do you need for a wire harness quote?

We typically require 2D schematics or 3D models showing the harness layout, a complete Bill of Materials (BOM) specifying wire gauges and connector parts, and any specific testing requirements. If available, a physical golden sample is highly beneficial.

Can you source specific brand connectors like Molex or TE?

Yes. As part of our comprehensive wire harness manufacturing support, we manage the supply chain for original, authorized components from leading global brands including Molex, TE Connectivity, Amphenol, JST, and Hirose to ensure compatibility and reliability.

How do you ensure the harnesses are not defective?

Every finished harness undergoes 100% continuity testing using specialized testing equipment to check for opens, shorts, and miswirings. We also conduct strict visual appearance inspections and pull tests on terminal crimps.

Do you support low-volume prototype runs?

Absolutely. We support OEM wire harness projects from the initial prototype and sample confirmation phase all the way to high-volume mass production, ensuring a smooth transition as your product scales.

What is your typical lead time for production orders?

Standard lead times range from 2 to 4 weeks depending on component availability and order complexity. Prototype samples typically take 7 to 10 business days. For urgent projects, we offer expedited manufacturing options to meet your deadlines.

Do you offer custom overmolding and waterproofing solutions?

Yes, we provide full in-house overmolding capabilities using PVC, PU, and TPE materials. Our solutions include IP67 and IP68 rated waterproof connectors, strain relief boots, and custom grommets for applications exposed to moisture, dust, or harsh chemicals.

What certifications do your cable assemblies carry?

Our manufacturing facilities are ISO 9001 certified, and our products comply with UL, CSA, CE, RoHS, and REACH standards. We can also accommodate industry-specific requirements such as UL758 for appliance wiring material and IATF 16949 for automotive applications.

How do you handle shipping and logistics to North America and Europe?

We offer flexible Incoterms including EXW, FOB, CIF, and DDP. Our logistics team coordinates air freight, sea freight, and express courier services (DHL, FedEx, UPS) with full tracking visibility. We handle all export documentation and customs clearance procedures for hassle-free delivery.

Can you provide customized packaging or private labeling?

Yes, we offer a full range of value-added services including custom polybag packaging, retail-ready blister packs, barcoded labeling, and private label branding. We can also apply custom heat-shrink tubing, sleeve marking, and laser-etched branding on connector housings.

What is your Minimum Order Quantity (MOQ)?

Our standard MOQ is 500 pieces for most cable assemblies, but this is flexible depending on the complexity of the design. For custom overmolded products, the MOQ may be 1,000 pieces. We are happy to discuss your specific volume requirements and find a solution that works for your project.
