DIN EN ISO 9001:2015
Certified by DEKRA Certification GmbH for the manufacture of plastic products by extrusion with in-house toolmaking, with an annual surveillance audit.
Heller Kunststoffe manufactures custom plastic profiles, hoses and round cords by extrusion: with in-house design, in-house toolmaking and fabrication through to ready-to-install components. Around 50 employees produce on 20 extrusion lines in Herborn, Germany, and we deliver worldwide as an AEO-certified exporter. Small series are welcome.
Ten industries, one standard: the profile has to perform in your application. Every industry page shows real sample profiles from our production, not stock imagery.
Four steps, zero external interfaces: that is what makes us fast and keeps quality predictable.
Often only the function and the installation situation are known. Our design department develops the profile geometry from there and advises on material, strength, temperature resistance and flexibility. Prototypes come from our own 3D printer.
More about manufacturingSeveral CNC-controlled wire EDM machines cut the extrusion tool to your drawing. Once the tool is finished you receive samples for trials and tests; series production starts only after your approval.
To toolmakingWe process PVC-U, PVC-P, PP, ABS, HD-PE, LD-PE, PA, TPU, TPV, TPS and EVA on 20 extrusion lines, including dual-hardness co-extrusion in a single profile.
View materialsPunching, drilling, printing, adhesive and hook-and-loop tapes, welded frames, mitre cuts or brush insertion: you receive a ready-to-install component, in fixed lengths or on rolls.
Fabrication in detail
Rigid carrier, soft sealing lip: co-extrusion joins two hardnesses in a single pass. Plus special compounds from UV-protected to UL 94 V-0.
What does extrusion tooling cost? PVC or TPE? And how does a sketch become a series? Our knowledge section answers the questions that come before every profile project: straight, specific and free of sales talk.
From granulate to profile: the process step by step, and when it beats injection moulding.
