Photovoltaic industry has been going through a rapid change over the last decade. In addition to rapid growth the industry has continued to witness a relentless price pressures along the PV value chain. The same is the case in the PV ribbon industry. Only PV ribbon producer that kept consistent product quality whilst maintaining low cost base and efficient production process remained competitive.
Plasma based annealing and tinning process represent an efficient PV ribbon production solution that will ensure consistent, top quality finished product at low cost.
Plasmait GmbH from Austria, the leader in designing and building PV ribbon machinery, has this year in Düsseldorf introduced a new PV ribbon annealing and tinning line designed for high output production. The new line features a maximum production speed of 210m/min. This allows the line to produce up to 250 tonnes of PV ribbon per annum in a typical production split between interconnect and bus bar ribbons.
Schmidt Maschinenbau GmbH from Gummersbach, Germany and Plasmait GmbH from Lebring, Austria integrated their machinery to develop a new drawing line for fine stainless steel and nickel alloy wires with an inline annealer.
Annealing of stainless steel and nickel alloy wires has until recently been done almost exclusively in the traditional tube furnaces in a multi-line setup. This is not the case anymore. PlasmaANNEALER can now be installed in-line with a fine wire drawing machines of Schmidt that produce fine stainless steel wires (dia. 1mm to 0.1mm) at the speed of up to 4-15m/s.
PlasmaANNEALER for fine stainless steel and nickel alloy wires has been awarded “Top Products of 2014” by the editors of Wire and Cable Technology magazine. Annealing of stainless steel and nickel alloy wires has so far been done almost exclusively in the traditional tube/strand furnaces. Energy coupling in the traditional furnace is not effective enough to allow high-temperature annealing to be done at drawing or rolling speeds. Stainless steel wires have been up to now always annealed in a multi-line setup. Continue reading
