Frequently Asked Questions (FAQ)
Q1
Do your products and factory have international certifications? We need to ensure compliance for our project.
Absolutely. Our factory holds ISO 9001:2015, ISO 14000, IATF 16949:2016, and SGS certifications. All materials comply with environmental directives. We fully understand that certifications are the 'passport' to the safe and lawful operation of your projects. Not only can we provide copies of the certificates, but we can also offer compliance document support tailored to your specific project.
Q2
What's the actual copper purity? Can you guarantee material consistency?
We use 99.95% minimum purity electrolytic copper (C11000) for optimal conductivity. Every batch comes with a Material Test Report (MTR) that traces it back to the mill. This means you get the same low resistance and high performance in every order, eliminating the risk of unexpected heat generation or power loss.
Q3
Can you make this complex design? How do we start?
Customization is our core strength. Send us your sketches, CAD files, or even just specifications. Our engineering team will provide DFM (Design for Manufacturability) feedback and a detailed 3D drawing within 48 hours for your review. This collaborative approach ensures the final product is both optimal for your application and cost-effective to produce.
Q4
Can I get a sample first? What's your MOQ?
We encourage samples! It's the best way for you to verify quality firsthand. For standard items, samples are readily available. For custom designs, we offer low-cost prototyping. Our MOQ is flexible; for standard products, it's as low as 10 pieces. For custom projects, we work with you to find an economical start quantity.
Q5
What's your QC process? Can we see test data?
Our QC is integrated at every step: material inspection, in-process checks, and final audit. With every shipment, you will receive a comprehensive Factory Test Report (FTR) including resistance measurements, Hi-Pot test results, and dimensional checks. This isn't just paperwork; it's your performance guarantee in black and white.
Q6
What surface treatment options do you offer for electrical copper busbars?
We provide professional surface treatments including tin-plating, nickel-plating, and silver-plating, as well as bare copper finishes. These finishes are designed to enhance corrosion resistance, lower contact resistance, and ensure long-term stability in harsh environmental conditions.
