Enamelled Wire
Precision wire engineered in multiple conductor materials and structures to meet demanding electrical and processing requirements across industries.
From 0.010 mm specialty wire to automated enamelling equipment, Jingte delivers complete solutions for demanding production needs.
Jingte offers two complementary product lines—high-performance wire and specialised enamelling equipment—to support complete manufacturing requirements from materials through processing.
Precision wire engineered in multiple conductor materials and structures to meet demanding electrical and processing requirements across industries.
Automated enamelling equipment engineered for stable output, consistent quality and efficient production.
Enamelled Wire Series
Choose the right product series by conductor properties, diameter range and strength requirements.
Enamelling Machine Series
Jingte combines advanced processes with automation control to improve productivity and product consistency across a wide range of manufacturing requirements.
Ultra-Fine Wire Enamelling Machine
Self-bonding enamelled wire has a dual-coat structure, with an additional thermoplastic, thermosetting or other bondcoat applied over the conventional insulation layer. The insulation is typically polyurethane, polyester or a related material. Jingte offers multiple insulation and bondcoat combinations to meet different application requirements.

Jingte developed its first single-head enamelling machine with metered pump enamel supply, advancing precision coating for ultra-fine wire.
The equipment entered production lines in China and overseas, demonstrating low failure rates and consistent output through long-term operation.
Continuous development produced a complete range of enamelling equipment covering 0.010 to 0.15 mm.
More than 200 machines have been delivered to electronic-component manufacturers in China and overseas, supported by an established maintenance system.
Precision manufacturing that sets a higher quality standard
A sealed high-purity nitrogen atmosphere isolates oxygen, preventing oxidation and maintaining a clean surface and stable material performance.
A precision gear-pump enamel supply with constant-pressure and constant-flow control maintains uniform film thickness and coating consistency.
Closed-loop tension control monitors and compensates for fluctuations throughout production to maintain dimensional accuracy.
In-line laser measurement captures and feeds back outer-diameter data for continuous dimensional monitoring.
