Hot-dip Tinning Process

Due to stiffer reliability requirements, electro-mechanical components are increasingly made of pre-tinned strips. Above all in the automotive industry, hot-dip tinning proved to be a superior corrosion protection surface treatment.

KMD group has mature hot-dip tinning technology. We have the first HDT line and HDT patent in China. Moreover, we are exclusive producer of Sn13 and Sn28m

Hot-dip tinning coating types
Sn10-pure tin Sn13-thermal tin Sn28M- tin silver
Coating-thickness-specifice advantages Lowest mating and unmating forces, wear resistant Temperature range above 130℃, improved electrical properties compared to pure tin, compatible with the new lead-free solders
Hot-dip tinning DIN EN 13149 (compliant with RoHS standards)
Thickness Width Coatings Coating thickness**
0.20-1.50 mm Up to 330 mm Pure tin, tin silver, thermal tin 1.0-3.0 μm2.0-5.0 μm4.0-10.0 μm10.0-20.0 μm

** Coating thickness ≤ 2μm on request

Packaging Service

We provide various supply formats for the customers to choose the most effective one for them

Pancake coils

Up to 1400mm outer diameter

Traverse-wound strip

Drums, traverse wound strips on wook, plastic or steel drums, or flangeless on cardboard or copper core.

Packaged weight: 300 - 1500 kg

Multilayer coils

Several large pancake coils are joined together by resistance welding and supplied palletised for use on pallet de-coilers. The multilayer forms on continous strip thus significantly reducing set-up time during stamping.
