Koch: Innovative OTA technology for quality wires

KOCH develops future technologies for the wire industry

Medical technology, power engineering, or mobility – quality wire plays an important roll in all progressive industries. The OTA technology that has been developed by system supplier Koch achieves the top qualities that are demanded. The drawing system enables non-diverted, straight-line drawing under a constant and reproducible counter tension. From pay-off to spooler – thanks to the linear wire drawing, especially accurate wire dimensions and high surface qualities are achieved.

Depending on wire quality, dimension, and requirements of the end product, different machines with OTA technology from Koch are employed. For the production of pre-stressing steel wire and spring steel wire using capstans with diameters of up to 1,200 millimeters, the KGT 47 OTA sets benchmarks. The machine’s size is compact and despite its tractions of up to 90,000 N, it generates very little noise. Also part of the OTA family is the KGT 25. It is especially suitable for low- and high-carbon steel wires as well as stainless steel wires. The KGT 16 produces fine wires and rope wires with diameters of less than 0.8 millimeters. Here, a dynamically regulated process optimization ensures the required accuracy. The OTA technology puts Koch in a leading position on the global market as it offers economical production with the utmost accuracy, reproducibility, and product quality.

As a system supplier, Koch designs, builds, and installs complete machine lines according to customers’ specifications. The company, which has been established for more than 90 years, has always made drawing machines in-house. Coilers and spoolers, which are also produced in-house, ensure that the wire is collected efficiently and carefully, even on heavy coils. Peripheral modules made by partner companies complete the machine lines, for instance, fulfilling functions such as cleaning the wire surface or treating it with copper, aluminum, or zinc. Customers in more than 60 countries value Koch’s technical know-how in the areas of engineering, drive technology, programming, and control.
