Why Freudenberg Sealing Technologies? – Your advantages

• Fast response to customer enquiries
• Shortest delivery times for seals and plastic turned parts thanks to flexible, shape-independent production on CNC-controlled turning and milling machines

These include, for example:

• Very large O-rings with internal diameters of more than 1. 000 millimetres, endlessly vulcanized in a special manufacturing process without butt joints and glued joints in accordance with DIN ISO 3601
• Very thin-walled diaphragms with wall thicknesses from approx. 0.2 millimetres
• The processing of a large number of special materials such as TFE, Viton GF, GFLT, FKM extreme, FFKM (perfluoroether)
• The new development of tailor-made, application-specific compounds in cooperation with reliable compounders

Production

More than 175 years of engineering and materials experience as well as our broad process engineering expertise make us a competent partner for individual customer solutions.

Modern machines ensure an optimal production process:

• CNC lathes and CNC milling machines
• Injection moulding machines (up to 300 t)
• Vulcanization presses (up to 500 t)
• Blank dosing machines, bar feeders
• Rolling mills
• Deburring machines
• Plasma parts cleaning systems
• Temperature control cabinets
• LASER marking system
• Polyurethane low pressure and high pressure dosing systems

Innovation

• Every year, the Freudenberg Group invests hundreds of millions of euros specifically in research and development. Freudenberg Sealing Technologies has been a driving force for innovation in sealing technology for decades. Sound materials expertise forms the basis for customized solutions.

• Only with a material designed for the specific application can the various requirements of elastomer products be successfully met. We optimise compounds according to your mechanical and thermal requirements, whereby media resistance is another criterion.

• Our in-house toolmaking department produces customer-specific prototypes and series moulds.

Prototyping with 3D Printing

With this alternative to mechanical production, we can produce prototypes using the inkjet process without the need for a tool mould.

The Advantages:

• Individual, fast and flexible advance production
• Reproducibility
• Precise manufacturing

Product Quality

• Efficient quality management, the expertise of our employees and modern production technologies guarantee the high-quality standard of our products.
• In consultation with our customers, we establish quality assurance parameters as early as the development phase to guarantee product quality from prototype to series production. Numerous safety approvals confirm the high quality of our products.
• Freudenberg Sealing Technologies is certified according to DIN EN ISO 9001:2015 and DIN EN ISO 14001:2015.

Product quality is ensured with the most modern measuring equipment:

• Measurement of indentation and compression hardness
• Tensile and compression measurement
• Abrasion measurement
• Optical 2D and 3D measurement
• Tactile measurement
