KME Germany GmbH & Co. KG 2.3.1. TECSTRIP®_multicoil The economical coil of Copper, Bronze and High Performance STOL® alloys. TECSTRIP®_multicoil is a system where several large pancake coils are joined together by resistance welding and supplied palletized for use on pallet de-coilers. Your advantage: Increased efficiency = increase of the productivity = cost savings when processing KME alloys. Standard thickness: Standard width: Warehouse requirements: ■ Height of pallet: max. 490 mm ■ Circular pallet ø: max. 1.600 mm ■ Pallet weight: max. 2.500 kg *) ■ Outer diameter ø: max. 1.600 mm *)...

KME Germany GmbH & Co. KG 2.3.2. TECSTRIP®_multicoil Potential savings using TECSTRIP®_multicoil The use of TECSTRIP®_multicoil optimises production, reduces coil changes and labour costs and keeps scrap to the minimum. (Example for strip dimension: 0,25 x 25 mm = 12 single coils) Saving of materials o up to 44 m strip material = minimizes scrap. Reduction of tooling time o up to 165 minutes longer machine running capacity through TECSTRIP®_multicoil o in comparison to 12 single coils without stamping starts of o single coils = productivity increase of approx. 13 %. Tooling – capacity o up...
