Production

Fireproof Mould
Storage

In order to maintain consistent high quality:

  • care maintenance
  • predictive maintenance
  • fireproof and heated mould storage

Production

Quality
Management

All items are produced acc. to

  • DIN EN ISO 9001, that means incoming goods inspection, continuous in-process control and sampling, final inspection and testing
  • CAQ computer assisted quality control
  • CPK value Process capability index
  • CMK Machine Capability
  • EMBP  initial sample test reports
  • Digital profile projectors
  • All required quality documents are delivered with goods or – on request – kept in our premises

Production

Test Lab

Continuous in-process controls monitor your items with most modern test technologies:

  • digital 2D-Measuring projector with automated tests
  • various modern computer aided measuring devices
  • Tensile and compressive testing equipment
  • Measuring pins and gauges
  • Digital microscopy up to 72 times magnification


As required by ISO 9001, all measuring equipment is subject to periodical calibration

Energy
Efficiency

Servo-motor-driven pump system significantly reduces power consumption

The goal of every plastic processor competing in international markets is to achieve both energy efficiency and reliable processes. A medium-sized injection moulding company in the Münsterland region has successfully achieved both goals. The key to their success lies in the choice of drive system for their hydraulic injection moulding machines.

Sustainability
concept

Electricity:
We source our electricity completely from renewable energy sources – completely CO2 neutral! Through this electricity supply from 100% hydropower, we save around 270,000 kg of CO2 every year.
Energy Efficiency:
Almost all machines are now equipped with particularly energy-saving servo motors and specially insulated injection units. This enables us to save an average of around 100,000 kg of CO2 annually since 2015.
Comparison: Link.
Hydraulic:
We no longer use synthetic hydraulic oil. All of our machines operate with a hydraulic oil based on domestic, renewable raw materials (sunflower oil), meaning no special waste is generated when cleaning and maintaining the systems.
In addition, this results in:
– Sustainable reduction in CO2 emissions
– Optimized energy efficiency
– Conservation of fossil resources


Lubricants
:
The lubricants we use are approved for use in medical technology and the food industry.
Cooling Water:
Our cooling water is completely free of chemicals – the systems are protected against corrosion and damage solely through special physical cleaning methods. We do not use any biocides or chemical inhibitors, so they cannot enter the groundwater. The waste heat generated by the machines is used to heat the production and storage halls as well as the adjacent offices.
Zero Granule Loss:
We participate in the initiative of the German Association of Plastics Converters: “Zero Granule Loss” and ensure that no granules are wasted or can enter the environment.
Waste Management:
Production waste is collected separately by material type and forwarded for recycling. These materials are then processed further in the plastics industry. All packaging materials such as papers, cardboards, and films are separated by type and also recycled. The small amount of non-directly recyclable production waste is prepared for thermal utilization.
