About us -
Kunststofftechnik Hans Rethwisch GmbH introduces itself

The success story of Kunststofftechnik Hans Rethwisch GmbH (KTR) began in October 1969: founded in Hamburg, the first article from our production was a capsule for dental filling material.

Since then, we have continuously expanded and improved: the original three small injection moulding machines have now become 24 electric and hydraulic injection moulding machines. In addition, we have also included 2C injection moulding, cleanroom injection moulding, assembly and finishing as well as mould management.

Despite several relocations, our family-owned company has remained true to its production site in Hamburg - quality "Made in Germany" is a commitment for us.

Strong competences for strong industries

We have built up expertise through our decades of experience. Having started out as a partner for customers in dental and petrol station technology, we now cooperate with numerous partners from a wide range of industries:

  • medical technology
  • aviation
  • automotive
  • construction industry
  • electrical engineering
  • mechanical and plant engineering
  • marine equipment
  • safety engineering
  • fuelling technology

We carry out both individual special designs and large-volume series productions.

Our company philosophy –
quality comes first

All our work is guided by the motto: "Quality is when the customer comes back, not the product!".

To achieve this, we not only rely on state-of-the-art technology, forward-looking quality planning (FMEA), continuous monitoring and the many years of experience of our employees in quality assurance and quality management in planning and production: we proactively address the requirements of our customers right from the initial consultation in order to always be able to offer the best possible solution.

We put together a customised service package for our business partners - from mould management to production to packaging, you receive exactly the services you need for your requirements.

We are certified according to DIN EN ISO 9001:2015 and EN 9100:2018 - customer-specific quality assurance agreements are also possible for customers with additional requirements.
