“Testing alone will not bring about quality; instead, quality must be produced.” – This principle is reflected in all of our processes and activities. Since the mid-1990s, our quality awareness has grown continuously to keep pace with the requirements of our clients and with our own demands. Ongoing development, regular certification of our QM systems and successful client audits are evidence of the importance that we attach to quality.

1983 First quality-assurance measures such as initial prototype test reports in accordance with VDA. Dimensional accuracy and production records become standard as part of the traceability of products and orders.

1995 The first QM manual was prepared, which described the production procedure and the corresponding checks in work instructions and inspection instructions. The first standardisations were carried out in the area of documentation.

1998 Introduction and certification of the first QM system in accordance with DIN EN ISO 9002

2001 Introduction and certification of a QM system in accordance with ISO/TS 16949

2005 Introduction and certification of an integrated management system based on ISO/TS 16949 and DIN EN ISO 14001

2008 onwards Refinement of the integrated management system (ISO/TS 16949 and DIN EN ISO 14001) with continuous improvement of the system.

From 2018 onwards, changes to meet the requirements of IATF 16949 will be implemented.

As part of our material checks, we use the following test methods and offer these as services to our clients:

  • Determination of peel adhesion forces DIN EN 1939
  • Determination of burning behaviour in accordance with DIN 75200, TL 1010 or MVSS 302
  • Thickness measurements using defined test weights in accordance with DIN 53855
  • Emissions test in accordance with VW TL 50180 (Fogging test, Formaldehyde, Total carbon emissions, Odour neutrality)
  • Weight determination/determination of the density/weight per unit area
  • Gauging tests based on customer specifications
  • Air permeability tests
  • Measurement of sound absorption adapted from DIN 52215

Environmental protection

Wool felt consists of natural fibres. These fibres are pure sheep wool, animal hairs and/or wool leftovers from spinning mills, and viscose fibres. As these are all natural materials, felt can be recycled or composted at the end of the product life cycle without any concerns.

As we guarantee type purity for synthetic needle felts and fleece materials, these can also be recycled without any concerns after they have fulfilled their intended purpose.

As a company, we also strive to structure our processes and working methods in such a way that we have the least possible impact on the environment. We document this for other interested parties as part of our environmental management system.
