SECO/WARWICK will supply a technological line for the heat treatment of fasteners to Gawel Screw Production Plant (GSPP), a manufacturer of screws for metal and wood based in Poland. The line, which will increase the production capacity at GSPP’s plant, consists of a PTE muffle-belt furnace designed primarily for carbonitriding, washing and annealing. It is adapted to work with endothermic gas from natural gas produced by an external generator. Installation is scheduled for the fourth quarter of 2017.
