Internorm Kunststofftechnik - testing and quality assurance at Internorm

The quality and reliability of our products have to be guaranteed. Therefore, the measures for implementing our QA standards have the highest priority.

Inspections: Constant quality control measures for all the products we produce. This is the only way to ensure a consistently high level of quality.

• We measure SHORE hardness values (hardness test for elastomers).
• We compare product dimensions with the drawings.
• We check products visually and mechanically.
• Material samples are analysed in our own laboratory.
• We develop our own testing options for some areas.

Our own testing regime: Before we use a material, test specimens are produced. Even months later, it is still possible to establish the quality of the raw materials. Everything is agreed and documented exactly. Our customers can receive test reports on request.

In the production process: We use the very latest measuring instruments. On the one hand, we fulfil our own demanding criteria; on the other, we have to comply with the QA system we have introduced. This work is supported by an efficient production planning and control system.

Accreditation: DIN ISO 9001 and DIN ISO 50001 accreditation means we are checked regularly by external specialists. The objective of our quality management is continuous improvement in all areas of the company.

Examples of applications

DOCUMENTATION FOR MATERIALS AND PARTS

We are happy to send you copies of our test certificates and initial sample test reports. Should you have any complaints, these are given priority.

MEASUREMENT OF GROOVES IN [PUR] ROLLERS

The very fine grooves that can be ground into your rollers on request can be checked with our laser measuring device. Such grooved profiles are mainly used to apply high-gloss varnishes.

MEASUREMENT OF TRUE-RUNNING ACCURACY

Producing high-precision cylinders for our customers is important to us. We measure the true-running accuracy of almost all cylinders after grinding. Upon request, we can send you a comprehensive test certificate together with the products.

CHECKING THE SURFACE ROUGHNESS

We check the surface roughness achieved after every grinding operation. This is crucial for varnishing rollers in particular as it has a huge effect on the application of varnishes.

CHEMICAL ANALYSES

If you already have a component but do not know what it is made of, then we can analyse samples for you to determine the type of polymer.
