Plastic manufacturing from a single source
Liedtke Kunststofftechnik is a manufacturing company founded in Velbert in 1974 specializing in industrial plastic components. The company stocks over 50 plastic types in over 500 dimensions as semi-finished products (sheets, rods, tubes, films), along with customer consignment warehouses and a cut-to-size service. Production includes CNC milling in 3- to 5-axis technology with tolerances down to ±0.02 mm, CNC turning with diameters from 2 to 500 mm, automatic lathes for series parts Ø 2–80 mm, CO₂ laser cutting and laser engraving, 3D printing (SLS, FDM, MJF, SLA, Polyjet) as well as waterjet cutting, stamping, polishing, edge bending, gluing, thermoforming and plastic welding. The material range extends from standard plastics such as ABS, PMMA, PC, PP and PE through engineering plastics such as POM, PA6 and PET to high-performance plastics such as PEEK and ECTFE, complemented by aluminium composite sheets (Dibond, Alucobond) and engraving materials. Customers include mechanical and plant engineering, electrical engineering, chemical apparatus engineering, electroplating, conveying technology, medical technology, aviation, signage technology as well as façade, trade fair and shopfitting construction. The company is certified to DIN EN ISO 9001:2015.
