PROTEC Machinery Park - Metal Fabrication in Poland

Metal stamping at PROTEC covers blanking, forming and bending of sheet metal on mechanical presses up to 400 t, hydraulic presses up to 450 t and pneumatic presses up to 40 t. Press lines with material feeders process coil material up to 10 mm thick.

• Press lines with material feeder - up to 10 mm from coil - continuous operation without sheet changes in runs of several thousand parts
• Mechanical, hydraulic and pneumatic presses - up to 400 t, 450 t and 40 t - press selected by part size and operation
• In-house tool shop - stamping dies designed and built on site - one supplier from tool to series

Laser cutting at PROTEC is performed on a Mazak 4 kW laser on 1500 × 3000 mm sheets - material up to 20 mm thick. A coil-fed laser cuts sheet up to 2 mm directly from the strip, without preparing blanks.

• 1500 × 3000 mm format - parts cut from a single sheet, without joining sections
• Sheet up to 20 mm thick - one process for structural and thin-walled parts
• Coil-fed laser up to 2 mm - material straight from the coil, no edge scrap typical of cutting from sheets

Profile cutting at PROTEC is done on a power hacksaw for steel sections and on circular saws for aluminium profiles - automatic and manual. Sheets are cut on guillotine shears, and aluminium profiles move on to the automated CNC machining centre.

• Power hacksaw - steel sections cut to length before welding and machining
• Automatic and manual circular saws - aluminium profiles in series and as single pieces
• Guillotine shears for sheet metal - straight cutting of sheets into blanks

CNC bending at PROTEC is carried out on CNC press brakes with up to 160 t and a bending length of up to 3000 mm - sheet up to 15 mm thick. CNC benders form flat bar and rails in copper, aluminium and steel.

• Bending length up to 3000 mm at 160 t - long profiles and folded parts without splitting the component
• Sheet up to 15 mm - structural parts and sheet-metal flashings on one technology line
• CNC benders for flat bar and rails - copper, aluminium and steel - repeatable bend angle in series production

Robotic welding at PROTEC takes place at MIG/MAG stations. TIG welding is done manually, and sheet from 0.15 to 1.0 mm is also joined by seam and spot welding. Welding processes are certified to EN 1090-2 and EN ISO 3834-2.

• MIG/MAG robots - consistent weld geometry and parameters across the batch in repeat runs
• TIG welding - manual, for joints that require individually guided welds
• Seam and spot welding machines 0.15-1.0 mm - joining thin-walled parts

CNC machining at PROTEC covers milling on CNC milling machines (max. part 1050 × 570 × 510 mm), turning on a CNC lathe with sub-spindle and bar feeder, wire EDM cutting, and surface and shaft grinding.

• CNC milling machines - max. part 1050 × 570 × 510 mm
• CNC lathe with sub-spindle and bar feeder - part machined on both sides in one cycle, continuous bar feeding in series
• Wire EDM machine - contour cutting in conductive materials, including hardened steel
• CNC centre for aluminium profiles - cutting to length, machining, punching and perforating
• Drilling machines, automatic tapping machines, surface and shaft grinders - complete part ready for assembly

Heat treatment at PROTEC is carried out in a chamber hardening furnace with a range of 100-1260 °C and a 350 × 500 × 300 mm chamber. Surface finishing covers shot blasting of carbon and stainless steel and vibratory finishing.

• Hardening 100-1260 °C, chamber 350 × 500 × 300 mm - required hardness for steel parts and tool components
• Shot blasting machines for carbon and stainless steel - cleaning and a uniform surface texture
• Vibratory finishing machines - deburring and edge smoothing across the batch

Assembly and packaging at PROTEC take place in a two-level assembly and kitting hall. Finished parts reach customers across Europe by our own fleet and freight forwarding. We manufacture to customer documentation, including from customer-supplied material.

• Drawing review before quotation - process selection by material, tolerances and batch size
• Assembly and kitting - sub-assemblies and kits ready for installation, fully automatic assembly and packaging stations for PV mounting components
• Local contact in Germany and Spain - sales offices in Cologne (protec.nrw) and Elche (es.protec.nrw)
