Otto Klumpp manufacturing Manufacturing

Quick throughput times, cost-effective production and injection moulding technology adherence to your required part quality using precision manufacturing processes.

One thing is particularly important when it comes to your moulded plastic parts: Precision

Manufacturing precision, adherence to your budget and faster throughput times. Your moulded parts must correspond exactly to your injection moulding requirements – regardless of how many of them you want to have produced.

At the same time, of course, you have to keep an eye on the budget during every production run. And last but not least, your moulded parts need to be completed quickly and reliably so that you can complete your products on time and fulfil agreements that you have made with your partners.

What do I need in order to have a precise manufacturing process?

In order to be able to manufacture your plastic moulded parts quickly, reliably and cost-effectively, you need the following:

  • Exact calculations – regardless of the complexity.
  • Manufacturing processes which are suitable for both mass production and precision manufacturing down to hundredths of a millimetre.
  • Qualified personnel who do not only perform complex calculations, but also carry out subsequent production in an efficient and cost-effective way.

This is exactly what you get from Otto Klumpp.
