A Name for Competence.

Our company, Ing. Lang & Menke GmbH, was founded in 1948 and today employs over 240 people. The production includes precision stampings, mounting and contact elements as well as securing and fastening components. The company Lang & Menke Kunststofftechnologie GmbH, which grew out of a cooperation with ISK Iserlohner Kunststoff-Technolgie GmbH, was formed in 2005.

The pooling of skills between the two firms brings together years of experience in plastics engineering on the one side and metal working on the other. This in turn generates synergies and innovative impulses from which our product developments, and hence also our customers, are able to benefit.


Reliable, state-of-the-art but environmentally friendly production – that is one of our hallmarks. Our constant focus is on meeting your quality standards - these are always the benchmark for our production.

Through regular internal and external training activities and our in-house workshop for training our apprentices, we ensure a high and uniform standard of qualification and skilling on the part of our employees - they are, after all, the biggest asset of our enterprise.

Unser zertifiziertes Managementsystem gewährleistet eine fortdauernde Kontinuität in der Produktionssicherheit. Ein wesentlicher Bestandteil ist dabei die computergestützte Überwachung der laufenden Fertigung.

Ergänzend zur prozessbegleitenden Qualitätskontrolle werden unsere Erzeugnisse vor der Auslieferung in der Warenausgangskontrolle nochmals auf die geforderten Qualitätsmerkmale hin kontrolliert.
