What Is Wire Coating Die
Wire coating die ( wire plating die ) is a kind of die widely used in industrial production. Its main function is to cover a layer of tin on metal surface. This tin layer not only improves the material’s corrosion resistance, but also improves its electrical conductivity.
Characteristics of Wire Coating Dies
Take widely used tin coating die as an example, HG tin coating dies are different from other wire dies in following points.
Working PrincipleBy electrolysis or chemical methods, ting coating die helps to deposited a layer of tin on the wire surface to improve its performance.
Special Titanium CasesNot like main wire dies’ stainless steel cases, tin coating dies’ case is titanium, which make it can float on the tin solution to coat wires.
Big Exit AngleExit angle of a tin coating die must be big enough to avoid the wire being stained by tin solution in coating process.
Application Fields of Wire Coating Dies
With the function of improving wires’ performance, wire coating dies are widely used in many areas.
Electronic IndustryTin has good electrical conductivity, so tin coating dies are widely used to manufacture circuit boards for many electronic products.
Automotive IndustryIn the automotive industry, tin plating dies are used to prevent the corrosion of automotive parts to extend the service life of automobiles.
Aerospace IndustryCoated wires can also be used in aerospace industry because of their excellent properties.
Specialized Production Technology
Compared with normal wire dies, production crafts of tin coating dies are more complex. Firstly, the case must be titanium instead of stainless steel. Then it needs to be cased for 2 times. Finally the tin coating dies can float on solution in tin plating process.


Even Tin Film
Even level of the coating affects much on wires’ performance. HG tin coating dies with designed geometry can plate an even tin film on your wires’ surface. After coating, the tin film combined with wires surface closely to improve their electrical conductivity and corrosion resistance greatly.
Consistence of Coated Wires
By controlling fluctuation of the tin coating dies’ specifications, consistency of HG wire coating dies are ensured. In this case, your wires’ diameters, roundness , extension will also be consistent and they will perform better in different industries and areas.

Most of our current customers use tin coating dies so we mainly make tin coating dies now.
If you need other coating dies, please feel free to inform us.
The cases are titanium. As for inner core, both PCD coating dies and natural diamond coating dies are available.
At present, customers usually use tin coating dies to coat copper wires and some alloy wires.
It’s ok , but the critical parameters still need your help ,say cases sizes, hole sizes, tolerance. We are able to suggest on angle , bearing etc..
After coating by our dies, you will get wires with even and firm tin films, which ensure the wires’ working results finally.
A little . Because production processes of tin coating dies will be more than that of normal dies. Moreover, the cases must be titanium.
