3 Mistakes to Avoid When Designing Rubber Extrusions

Whether you are improving an existing product or creating a brand-new product, appropriately designed rubber extrusions are vital in order to maintain consistent product quality. Here are three mistakes to avoid when designing rubber extrusions for your project

Sharp Corners

While 90-degree corners are ideal in many applications, rubber extrusions are not one of these applications. Indeed, rubber extrusions are used in many 90-degree applications, however, sharp corners in the extrusion itself can lead to leaks. It is best to include a small radius in the sealing surface design instead of a 90-degree angle.

Failing to Account for Movement

Since compression loads can vary greatly, compression and decompression must be accounted for when designing your part. If not taken into consideration, the part can end up too big or too small, and this will lead to leaks.

Designing it Alone

You will want to choose a supplier that has a dedicated team of highly-trained experts in their field, that can help take your vision and turn it into a reality. You will want a supplier that knows the ins and outs of the various materials available and that can help you to choose the material that will work best in your specific application

Filling voids with reliable seals is a constant challenge in industrial environments. Without the right fit, seals won’t perform their job right, resulting in poor performance and even the contamination of sensitive environments. This is where Elbex’s ribbed rubber profiles come in. Our custom ribbed sealing profiles offer superior compression and sealing power by being tailored to your specific application needs. Here’s how our custom ribbed rubber profiles can make a difference for you. The Function and Superiority of Ribbed Sealing Profiles Ribbed sealing profiles play a vital role in manufacturing and industrial applications by filling voids or gaps between two surfaces to create an effective seal. However, ribbed rubber profiles take things even further, as their “ribs” significantly increase the profile’s ability to compress and fill irregularities. This results in a tighter and more durable seal than what you would find with a smooth profile, which also makes ribbed profiles far more versatile. Custom Design is Our Standard for Industrial Applications We are proud of our ability to deliver custom-manufactured ribbed sealing profiles that meet your exact requirements. We can work with you directly to develop the perfect custom ribbed rubber profile, as our extensive capabilities allow us to meet almost any design. Aside from the design itself, we use top-quality materials to help our seal products withstand harsh environments, including direct sunlight and chemical exposure, so the finished profile will deliver lasting performance. Leveraging Elbex's Comprehensive Engineering Expertise At Elbex, we are committed to delivering dependable support throughout the design and engineering processes. Our in-house tool and die design capabilities allow us to create custom ribbed rubber profiles in a way that meets your budget and timeline needs.

Choosing rubber materials can make all the difference for the performance and longevity of your rubber extrusions. The wrong choice can lead to compromised performance and even product failure or costly redesigns – so it’s normal to feel overwhelmed by this decision. Fortunately, with Elbex’s data-driven material selection criteria for specific rubber extrusion applications, you don’t have to leave this chance. Here’s how we help you pick the right materials, every time. The Guiding Questions: Elbex's Strategic Selection Process Choosing the right materials largely comes down to asking in-depth questions to understand the application and its operating environment. Our engineers ask critical questions like: What will the part’s primary function be? What are the application’s temperature requirements (both high and low)? Will the part be exposed to specific chemicals or fluids? Will the part be located indoors or outdoors (UV, ozone, weather exposure)? Does the part need to meet any regulatory requirements, such as food-grade, fire-retardant? What is the target cost per part?  The answers to these questions allow us to select the right compound for each extrusion, ensuring optimal performance while still fitting within your budget. A Closer Look: Key Elastomer Properties & Their Applications When selecting rubber materials for different applications, we look at their distinct characteristics. For example, durometer (or hardness) directly impacts a material’s sealing and abrasion. You generally want a softer material for better sealing, but harder for durability. Here’s how some of the most common elastomers compare: Silicone rubber: Silicone rubber properties include solid performance in both extremely hot and very cold temperatures, excellent flexibility, and strong UV/weathering resistance. Silicone is often used in high-heat applications, as well as the medical and food industries. EPDM rubber: Common EPDM rubber applications include outdoor seals, gaskets, and weatherstripping. This material’s resistance to water, ozone, sunlight, and weathering make it great for outdoor use. Neoprene rubber: Neoprene rubber applications can be quite varied thanks to its resistance to oil, heat, and flame. This versatile, all-purpose material is often a good fit for industrial and automotive applications. Nitrile rubber: Like neoprene, nitrile rubber applications often include the automotive and manufacturing industries thanks to its excellent resistance to oils, fuels, and many chemicals. The Elbex Advantage: Expertise at Your Service Choosing rubber materials is a critical step in any project. With Elbex on your side as a true collaborative partner, you get the unparalleled expertise and guidance you need to make the right choice, every time.
