Precision copper busbars and connectors finished with durable epoxy powder coating.

Rigid copper busbars finished with epoxy resin powder for excellent insulation, corrosion resistance and a smooth, durable surface.

Multi-terminal copper connection bars with colour powder coating — reliable conductivity with full insulation between contacts.

Laminated flexible copper connectors coated for battery-pack links, combining flexibility with a protective insulating layer.

Bespoke copper connectors dip-coated to your drawings — any bend, length or finish colour for specialised applications.
Our dip-coating process upgrades copper busbars on six fronts — lowering cost while extending service life.
A dense epoxy layer seals copper from moisture, salt spray and oxidation for lasting reliability.
The cured coating resists abrasion and mechanical wear during assembly and daily operation.
High dielectric strength prevents short circuits and allows tighter, safer busbar layouts.
A smooth, even, colour-customisable surface gives every part a premium, professional look.
Longer-lasting parts cut replacement and maintenance spend across the product lifecycle.
Combined protection significantly extends the working life of connectors in harsh environments.
Four controlled stages ensure a consistent, high-quality finish on every batch.
Degreasing, cleaning and activation prepare the copper for maximum coating adhesion.
Pre-heated parts are dip-coated in epoxy resin powder for a uniform, fully-enclosing layer.
Parts are cured in temperature-controlled ovens so the coating bonds hard and even.
Thickness, insulation and appearance are checked before careful packing and shipment.
