Automotive industry / machine and special system construction
Moulded rubber parts and seals solve a wide range of problems in both automotive and mechanical engineering. For example, in the transmission of forces, the damping of noise and vibrations or wherever sealing, testing and insulation is required. Whatever the application, whether seals for standard applications, precision articles or demanding components that are exposed to high service temperatures or aggressive media - Heinz Gräber is your partner when it comes to rubber!
We are constantly developing our medical technology products and are always happy to respond to individual customer requests. This results in quality products made of rubber, polyurethane (PUR) or silicone - in all volumes, sizes, and quantities.
Our silicone moulded parts are used in various applications for medical devices, apparatus, and systems. Special rubber compounds are used for this purpose, which optimally fulfil every medical and hygienic requirement.
Furthermore, all our silicone and rubber parts have been extensively tested and comply with all relevant standards, for example with regard to fire protection. For example, we use silicone to manufacture membranes and collection containers for dialysis machines using rubber seals of every kind.
Conveyor technology places the highest demands on elastomer properties. For example, applications based on nitrile rubber for drive wheels or heavy-duty rubber-metal wiper elements.
Heinz Gräber GmbH also offers comprehensive know-how and suitable rubber compounds for rollers. From the surface itself, right up to our customers' requirements with regard to various applications. We manufacture rollers e.g. for mechanical engineering, the steel and metal industry, film production and finishing, the printing industry, the plastics industry, or the paper industry.
The variety of products and the application of numerous flavourings can have a wide range of effects on elastomers in this industry.
Heinz Gräber GmbH offers a new sulphur cross-linked compound series, which comes with a wide range of European certifications such as W270, WRAS and ACS. Furthermore, the recipe structure complies with the requirements of the positive list for aqueous food in accordance with the FDA.
In the aerospace industry, our moulded rubber parts are required to withstand the most extreme requirements.
Therefore, for this purpose, we use rubber with the following properties:
Excellent electrical insulation properties, high temperature resistance, elasticity over wide temperature ranges and a high degree of flame retardancy.
We rise to the extremely high demands of this industry to ensure that our products will continue to contribute to safety in modern rail traffic both now and in future. Great importance is attached to the resistance of thematerials used, which are often exposed to extreme temperature fluctuations.
Heinz Gräber GmbH has developed rubber compounds that are specially designed for these conditions. This allows maintenance costs to be reduced over the entire life cycle.
Water, oil, and gas
Our drinking water supply seals are made of innovative and efficient rubber compounds which can still be used for drinking water even after 2021.
Extracting and processing oil and gas is complex and requires special technologies. Modern plants are required to function economically and reliably under extreme environmental conditions. Our moulded rubber parts such as seals, O-rings and custom moulded rubber components withstand factors such as heat, cold, moisture, temperature fluctuations, corrosion, or UV radiation, depending on their application.
