Rubber Extrusions

Rubber Extrusion is a process which forces uncured rubber compounds through a die and into the desired shape. Once extruded it is immediately cured. Our process utilizes a continuous salt bath cure line. The uncured extrusions will run through a salt line at approximately 400˚ F and emerge fully cured, with the different components of the material being cross-linked.

The Basics

Unlike other methods, the extrusion process lends itself well to high volume lineal foot production runs. By using a salt bath cure system, we are not restricted to limited product lengths, such as with an autoclave cure system. Extrusion also allows a higher volume of material to be processed in a shorter time, whereas the molding process produces a set number of parts per cycle. In general, rubber extrusions are produced in accordance with established RMA tolerances.

With our main focus being on custom design manufacturing, there are minimum order requirements. The minimum order requirement will vary with profile size and material. Our production runs are based on at least a full batch of material. Material batch sizes can range from 100 lbs for Silicone up to 500-600 lbs for EPDM and other materials. Sponge compounds will also have a much higher yield than dense compounds.

Extrusion Tool & Design Die

An extrusion die is a steel blank that is precisely cut to the shape of the cross-sectional profile of the desired part. Once in place, raw material is forced through the die and cured to create the profile. Due to unique characteristics of different materials, dies are material and durometer specific.

Beyond Standard: Industrial Rubber Profiles for Demanding Applications

By Katie Schupp • December 27, 2024

Industrial manufacturing processes require precision and performance. However, it’s not always easy to find the materials that will withstand the harsh conditions and specific functional requirements present in an industrial environment. At Elbex, our specialized rubber profiles for industrial manufacturing ensure optimal performance, longevity, and cost-effectiveness for your application. Understanding Industrial Rubber Profiles Industrial rubber profiles play a key role in a wide range of industrial and manufacturing activities by providing sealing, insulation, protection, and vibration dampening. They include extruded profiles (including U-channels, L-shapes, and T-shapes), molded profiles (such as custom shapes and seals with complex geometries), and sheet rubber with die-cut profiles. At Elbex, we can customize these profiles to better match the specific needs of your application. A wide range of industries rely on rubber profiles during the manufacturing process, including the automotive, construction, appliance, mass transit, and architectural fields. Rubber profiles serve a wide range of roles, including as gaskets and seals in machinery to absorb vibrations, or as door and window seals to prevent leaks. Materials and Properties Industrial rubber profiles can be made from several different rubber compounds, including EPDM, nitrile, silicone, and neoprene. Each of these materials offers varying levels of resistance to abrasion, chemical exposure, extreme temperatures, UV exposure, moisture, and other hazards. At Elbex, we work with you to determine which material will be best based on your performance needs and environmental factors affecting your application. Choosing the Right Rubber Profile Choosing the right rubber profile requires examining the specific needs of your industrial application. For example, will the profile be involved in sealing, insulating, or offering protection against vibrations? What environmental conditions will be present? Do you want to prioritize flexibility, hardness, or durability with your profiles? And of course, what solution will be cost-effective while still delivering the desired performance? By considering these questions together, we can determine the best solution for your application. Durable industrial rubber profiles can enhance the performance and efficiency of various industrial and manufacturing processes – but only if they are made with quality materials and feature the right design specifications. Contact Elbex today to request a quote or schedule a design consultation to see how we can meet your industrial rubber profile needs.

Choosing the Right Dishwasher Gaskets: Watertight and Worry-Free

By Katie Schupp • December 20, 2024

A leaking dishwasher can be incredibly frustrating and problematic for its owners, with the potential for damage to the machine itself and widespread water damage in the kitchen. For manufacturers, this makes utilizing high-quality dishwasher rubber seals and high-quality silicone gaskets for dishwashers essential for providing reliable performance without risking costly leaks for customers. Types of Dishwasher Seals Dishwashers actually utilize multiple types of seals to prevent leaks. The door seal and gasket is the most noticeable to users, as this creates a watertight seal between the dishwasher’s door and the tub. The tub gasket also plays a vital role in preventing leaks between the dishwasher tub and the surrounding countertop and cabinets. Finally, pump seals, hose seals, and spray arm seals help ensure the proper performance of these components by preventing vibrations and leaks. Materials and Durability Silicone and rubber are the most commonly used materials for dishwasher seals. These seals are exposed to heat, moisture, detergents, and food particles, which can accelerate wear and tear. Generally speaking, silicone offers better resistance to extreme temperatures, as well as oils, fats, and grease. However, rubber is more tear-resistant. As such, consider the dishwasher’s temperature settings and intended usage environment as part of your materials selection. Signs of a Failing Dishwasher Seal Even with the right materials and design, a dishwasher seal can fail over time. The most obvious sign of a failing seal is a leak – water pooling beneath the dishwasher. Mold growth, musty odors, or decreased cleaning performance could also indicate that a seal is deteriorating. Using high-quality materials and the right design will optimize the performance and longevity of dishwasher seals and gaskets. High-quality water-resistant seals and gaskets are essential for preventing leaks and ensuring optimal performance in dishwashers. By emphasizing these elements during the design and manufacturing process, you can deliver quality outcomes to your customers. Contact Elbex today to learn more about how we can help produce dishwasher rubber seals and gaskets that meet your manufacturing needs.
