Detail Specifications / Descriptions
*We develop and product single screws and twin-screw, their diameter ranges up to 132mm and their length to 3700mm . We only use material that imported from Germany or Japan once the geometry has been determined. The screws are produced by the following individual processes.● The blanks are prepared and annealed
● Modern CNC-lathers ensure a high degree of constant quality
● Well-Proven special boring systems are used for producing the cooling channels
● The screw geometry is milled out by computer numerical controlled machines
● Before they undergo heat treatment, the workpiece are checked for warppage. Deviations are corrected immediately
● The screw flights are polished by several stages, surface roughness below Ra 0.8 g m
● An acceptance report is written out of each screw during final inspection
