Custom conductor manufacturer since over 10 years
Conductors That Survive Ten Million Flex Cycles
Tinsel wire, speaker lead wire, copper stranded wire, precision copper foil and heater wire, engineered around the bending, resistance and solderability targets your cable has to hit.
Superfinewire Technology
A Conductor Is A Design Decision, Not A Commodity Line Item
Five conductor families, one engineering question: what does your cable have to survive?
What We Make
Highly flexible, high-strength metal conductors: tinsel wire, speaker lead wire, extremely fine copper foil, copper stranded wire and heating wire, plus conductors in special metals on request.
Who We Serve
Cable and component makers building medical wires, robot wires, aerospace cables, military special equipment cables, charging pile cables, automotive circuit electronic cables, drag chain cables, consumer electronics cables and textile wires.
What We Solve
Standard solid wire breaks where a cable flexes, swings or gets soldered repeatedly. We build the conductor so the finished cable meets its resistance, outer diameter, tensile strength, swing and solderability targets at the same time.
Why Customers Stay
We design conductors that differentiate our customers from their competitors, across speakers, automotive, medical and textiles, and keep iterating the product as the market moves.

What Problem We Solve
Your Cable Fails At The Conductor, Not At The Jacket
Every lever below changes one of the five targets a conductor has to hit at the same time.
Where cables actually fail
- Solid conductors work-harden and fracture at the flex point.
- Thinning a wire for flexibility pushes resistance past what the circuit allows.
- Fine conductors oxidize and stop taking solder cleanly.
- Heating elements need a resistance value in something that still bends.
- Shielding stiffens the cable it was meant to protect.
What we change to fix it
- The foil: bare copper, plated, or alloy for mechanical headroom.
- The fiber core: nylon through aramid and liquid crystal polymer.
- The structure: single-layer or multi-layer foil, stranded or mixed with copper wires.
- The plating: tin, silver or nickel, 0.3 um to 2 um.
- The verification: resistance, tensile, elongation and salt spray before it ships.
Inspection Equipment Control
The Exceptional Quality Of Our Wire Conductor
Resistance, tensile strength, elongation and corrosion resistance are measured on our own instruments before anything ships.
DC Resistance Tester
Measures the resistance parameters of the wire conductor precisely. It is the key tool for confirming power safety, product quality and equipment reliability before a lot ships.
Tensile Strength Tester
Measures the physical properties of the material through the tensile process, including tensile strength, yield strength, elongation and elongation after fracture.
Elongation Tester
Measures the elongation rate of the wire during stretching, which is how we evaluate the mechanical properties and mechanical strength of the material.
Salt Spray Test
Simulated salt spray environment for artificially accelerated corrosion testing, used to check the corrosion resistance of metals, coatings and electronic components.
Inside The Plant
Two Shifts, Running Without Interruption
Sample testing is available on conventional and customized products with no minimum order quantity.
