Quality First: Inside LiRui’s USB Cable Factory
At LiRui, we focus on making data cables that are durable and fast. From the copper wire to the final packaging, every step is controlled in our own workshop to ensure stable quality for your brand.
Here is a look at our production process.
1.High-Quality Core Materials
We prioritize conductivity and stability。
Pure or tinned copper Cores: We use high-purity (tinned) copper. This reduces resistance and ensures the cable supports real fast charging (PD and QC protocols) without overheating.
Double Shielding: Inside the cable, we use aluminum foil and metal braiding. This strengthens the wire and protects data transmission from interference.
2.Strong Connectors (Injection Molding)
A good cable needs a strong joint. We use Integrated Injection Molding technology.
One-Piece Molding: We mold the inner plastic and the outer shell together. This keeps the internal wiring safe and prevents the connector from snapping off.
Reinforced SR: We design the Strain Relief (the cable neck) to be flexible and thick, so it can withstand daily bending.
3.Strict Lab Testing
We verify our quality through rigorous testing data before mass production:
Salt Spray Test: We test connectors in a saline mist 48H to ensure they resist rust and oxidation, even in humid environments.
Bending Test: Cables undergo 3000+ continuous 90-degree bending cycles to prove they won't break internally.
Plug-in Test: We test the USB-C and USB-A plugs thousands of times to ensure they stay tight and secure.
5.Customization Options
We are ready to build cables to your specs:
Materials: PVC, TPE, or Nylon Braided.
Specs: Custom lengths (1m, 2m, 3m) and custom OD (cable thickness).
Safety: All materials are RoHS compliant.
