Injection-molded parts and assemblies – from design through in-house toolmaking to series production
KINDTNER Kunststofftechnik GmbH
Künzelsau-Amrichshausen (74653)New on Amplifa
Plastics technology for over 40 years
KINDTNER Kunststofftechnik GmbH, based in Künzelsau-Amrichshausen, is an owner-managed family business that has been active in plastics injection molding and toolmaking for over 40 years. Its core competence is the production of injection-molded parts on injection molding machines with clamping forces of 400 to 6500 kN and shot weights of 0.05 to 3000 g, including 2-component technology. The company supports customers from the product idea through design and prototyping to series production, and additionally offers assembly and ultrasonic welding. The in-house toolmaking department builds, maintains and repairs injection molds; on request, mold making is carried out by qualified network partners in Germany and abroad. The in-house QA department works with an imaging 3D measurement system. The company serves a wide range of industries including ventilation technology, electrical engineering, hygiene, sensor and control technology, children's toys, sound systems, laboratory technology and the automotive sector, and is certified to ISO 9001:2015.
