The stripping and tinning of enamelled copper wire is a key process in the production of modern electrical and magnetic components. In e-mobility in particular, manufacturers must reliably strip and tin enamelled copper wire to ensure reliable electrical connections and a high thermal load capacity.
New generations of wire with innovative insulation systems significantly increase the demands on the process. Traditional mechanical or chemical stripping processes are increasingly reaching their limits here.
Stripping and tinning enamelled copper wire using selective soldering technology
EUTECT offers solutions with which enamelled copper wire can be stripped and tinned in a single process step. The selective soldering process used enables thermal stripping of enamelled copper wire directly during the tinning process. There is no need for upstream mechanical or chemical removal of the enamelled insulation.
The advantages at a glance:
- Inline process without additional processing steps
- Clean contacting without damaging the conductor
- High process stability for series production
- Suitable for high-temperature resistant enamelled wires
Process parameters for reproducible paint stripping and tinning
Precise coordination of all process parameters is crucial for a stable enamelled copper wire stripping and tinning process.
These include:
- Soldering alloy
- Flux
- Temperature-time profile
- Continuously guided solder melting
Only through the optimum interplay of these factors can enamelled copper wire be reliably stripped and tinned, especially in modern insulation systems with high thermal resistance.
High-temperature soldering systems up to 475 °C for enamelled copper wire
For demanding applications, EUTECT has developed special systems with which enamelled copper wire can be stripped and tinned even at high temperatures.
The most important features are
- Process temperatures up to 475 °C
- Solder wave generated by induction pump
- Safe removal of insulation residues directly at the tinning point
- Uniform solder flow for stable results
In addition, complete nitrogen gassing ensures an oxide-free process environment. This ensures high-quality, uniform tinning of the wire ends.
Optimisation for e-mobility and industrial series production
EUTECT's solutions enable enamelled copper wire to be stripped and tinned reliably, even under the increasing demands of modern e-mobility and industrial applications. By integrating stripping and tinning into an inline process, process complexity is significantly reduced, while at the same time ensuring high repeat accuracy and stable series processes.
Enamelled copper wire is stripped and tinned reproducibly and without additional processing steps, which reduces process costs and minimises sources of error. At the same time, new types of enamelled wire that can withstand high thermal loads can also be processed reliably. This combination of efficiency, process reliability and material flexibility makes the technology particularly relevant for applications in electromobility, coil production and power electronics.
