Plasmait - Plasma Industrial Technologies

Plasmait is a supplier of plasma based heat and surface treatment solutions to the metals industry. We lead the field of continuous high-temperature plasma heat treatment applications. Our solutions are designed for demanding surface requirements and coating applications.

We help our clients develop, deploy and improve their production lines in the wire, tube, rope, profile and rod industry. We build specific heat and surface treatment machinery or develop new production processes from conception to deployment.

Plasma Cleans and Anneals Conductors in-line with Taping

Conductors used for taping lines have traditionally been annealed in bell furnaces. Batch annealing can result in uneven recrystallization and surface quality issues like sticking of flat products. Batch annealing is followed by wet and/or mechanical surface cleaning before the conductor is fed into the taping line.

To address shortcomings of the batch annealing process Plasmait GmbH introduced a new PlasmaANNEALER that was designed to anneal and clean round or rectangular conductors in-line with a conventional taping line.

SolarSoft Project Successfully Completed: Super-Soft PV Ribbon Produced at High Speed with the Help of Plasmait

SolarSoft – an industry consortium ( – led by Strip Tinning Ltd from Birmingham UK has successfully completed the development of a new PV ribbon production process that allows high-speed efficient and chemical-free production of super-soft PV ribbon. With the help of Plasmait and University of Birmingham the consortium achieved the aim set out from the start: to produce a tinned copper ribbons with low yield strength, the type that are required for interconnecting thin crystalline solar cells.

Fine Stainless Steel Wire Can Now Be Annealed In-line with Drawing

It has been widely accepted that stainless steel and nickel alloy wire cannot be annealed quickly enough to go in-line with a drawing or rolling machine. This is now a thing of the past. Plasmait has introduced a new PlasmaANNEALER that is first in the world to anneal fine austenitic stainless steel and nickel alloys wire at the speed of drawing. This new concept allows for a radical increase of continuous annealing speeds that can surpass 20m/s in the case of fine wire sizes of austenitic stainless steels. Continue reading
