What is EPDM Gummi Formteile
EPDM Gummi Formteile is a rubber product made by processing EPDM rubber into a specific shape. These shapes can be circles, squares, rectangles, rings, or any other desired shape. Gummi Formteile is widely used in the automotive industry, construction industry, electrical industry, and industrial equipment for sealing, isolation, buffering, protection, and other applications.
Rubber Gummi Formteile
To produce rubber molded parts, the rubber mixture is introduced into a specially designed metal mold. The desired geometry is first formed by pressing or injection, and then the mixture is stabilized by vulcanization. This process gives the material specific elastic properties.
Rubber gummi formteile is particularly suitable for damping, sealing, insulation, and protection and therefore offers almost unlimited application possibilities. They can be used as rubber buffers, seals, etc. in all areas of mechanical and plant engineering, electrical and vehicle construction industries, energy technology, as well as agricultural technology and environmental technology. Most rubber gummi formteile are not standard parts or standard parts, but are developed for specific functions by our product development team working closely with customers, and then manufactured to order.

Advantages
- Multifunction
EPDM gummi formteile has elasticity, pressure resistance, wear resistance, and mechanical and chemical toughness. Different application conditions and required functionality determine the choice of materials and type of manufacturing process. Each production process has its characteristics and must therefore be accurately matched to the production order and associated purchase quantities. We can achieve single-piece production, batch production, and mass production through our strategic partners.
- Tailor-Made
Gummi formative can be affected by changes in the medium, temperature, and climatic conditions, mechanical stress, or exposure to ozone and UV rays from sunlight, which limits its service life and service life. To ensure high quality, we rely on our material development and production.
For this purpose, we carry out mechanical and dynamic tests, vulcanization and processing tests as well as material and damage analysis in our development laboratory. For further analysis (such as electron microscopy), we also bring in advanced scientific instruments.
Gummi Formteile production process
In addition to conventional vulcanizing machines using displacement molds and transfer molds for the compression molding process (CM) and transfer molding processes, we also have state-of-the-art injection molding machines for the injection molding process (IM) to produce rubber molded parts.
Including the coordination of materials, production methods, and production processes to achieve economic optimization in production and application. The use of cold runner technology also contributes to this, which also helps protect the environment and resources.
- CM process (compression molding process).
- TM process (transfer molding process).
- IM process (injection molding process).
- Injection molding and embossing process.
- Precision molded parts weigh approximately 0.1 to 5,000 g.
Our advantages
- Linde Polymer Gummi Formteile: Flexible shapes and a wide range of applications
EPDM gummi formative has excellent properties and a wide range of applications. As a buffer, spring, or sealing element, it is ubiquitous in daily life. Although they are rarely recognized, they are indispensable components in a variety of industries and can be used to absorb shock, seal, protect, or insulate. The versatile gummi formteile has good elongation properties and is therefore extremely elastic, allowing maximum design freedom. They are also pressure-resistant, wear-resistant, mechanically, and chemically elastic. Therefore, they are widely used in the electrical industry, mechanical and plant engineering, the automotive industry, and many other process industries.
Depending on the application conditions and required functionality, these components are manufactured from elastomer materials through appropriate production processes. Linde Polymer is your trusted supplier of molded rubber parts in a variety of designs. Whether you require small batches, large batches, micro or high-volume products, as experts at Gummi Formteile we can mold a wide range of elastomer materials for you.
- Production of Gummi Formteile according to customer-specific requirements
Linde Polymer has a wide range of machinery consisting of compression presses, injection molding machines, CNC cutting machines, CNC precision automatic lathes, sandblasting systems, and painting stations to provide a wide range of options for the production of molded rubber parts. We produce black or colored molded rubber parts using compression molding, transfer molding, injection molding, or injection compression molding from standard materials such as NR, NBR, EPDM, or CR, as well as high-quality elastomers such as ACM, FPM, or HNBR. Depending on the material, we can offer different hardnesses from approximately 25 to 95 ShoreA and can also produce molded rubber parts to FDA or food-grade standards based on BfR recommendations. We can produce small, medium, or high-volume products in weights ranging from 0.1 grams to 5,000 grams, and of course can also customize special qualities to factory standards or user specifications based on your requirements based on sketches, drawings, or samples.
- From consultation to finished product Gummi Formteile
During the initial technical discussion, we analyzed your expectations and requirements for Gummi Formteile and provided you with an appropriate design solution that allows us to manufacture a single precision molded part of impeccable quality. During this process, we take into account the cost-effectiveness and service life of the tool, taking into account parameters such as batch reduction, number of calibers, part geometry, and material properties. The final design solution is first implemented in sample parts and then in actual tool manufacturing. We produce prototypes quickly and cost-effectively using injection molding master molds or small single-bore transfer or compression molds. The tools used to produce Gummi Formteile are manufactured by us on state-of-the-art equipment from high-quality steel, so their quality has a decisive influence on the quality of the components. Long service life is guaranteed! Of course, the focus of finishing and quality management is also to achieve the best possible quality results. Linde Polymer stands for 100% service, performance, and quality – a philosophy that extends from consultation to finished molded rubber parts.
