Knowing the Tolerances of Silicone & Rubber Extrusions

ELBEX • November 12, 2018

In order to assist in the creation of an effective, efficient rubber extrusion it’s important to know the tolerances of our rubber and silicone products. 

Extrusion tolerances for standard and custom cross-sections, plus material tolerances, are all important to us at ELBEX Corporation.

We have detailed PDFs which outline our extru-sion tolerances for technical reference. Our tolerances include outside diameters, inside diameters, walls, width, height and general dimensions of our extrusions. Quality extrusion control is also highlighted in these documents. 

We have documents detailing standard cross-section tolerances, cut length tolerances for unsliced extrusions, irregular and cored cross-section tolerances.

The PDFs available on our website provide additional details. 

At ELBEX, we strive to provide our customers with quality custom extruded products that meet their exact criteria. That’s why we are proud to offer our commitment to quality and reassure our customers with our ISO 9001:2015 without design certification. This ISO cer-tification ensures the quality, safety, and reliability of our products, as well as highlights our capabilities such as in-house tooling, cutting, taping, and packaging to our customers’ requirements. 

The entire team at ELBEX is dedicated to meeting and exceeding our clients’ expectations. We take pride in our accreditations, expertise, and ability to deliver for our customers.

It’s all too common for off-the-shelf-parts to fall short of what you need. This makes designing custom rubber extrusion profiles for specific applications an absolutely critical aspect of getting the precision and unique functionality you need for each application. As a premier provider of customized extrusion solutions, Elbex can provide custom rubber extrusion designs that are perfectly tailored to your needs. The Elbex Philosophy: Every Application Is Unique At Elbex, we understand that every application is unique. We actively listen to your specific project requirements so we can understand your exact needs. Whether you have a detailed drawing, a simple sketch for quoting, or even a physical sample for reverse engineering, we can use it as a baseline for getting started. With our team’s knowledge, we can then recommend the most suitable design, material, and manufacturing approach for your component. “Hands-On” Engineering: Your Dedicated Project Quarterback After you request a quote, we assign a dedicated engineering team leader (your "quarterback") to your project. This person takes the lead on your project with all communication and oversight to ensure timely and satisfactory completion. From plan visits and field support to in-depth tooling and engineering setups conducted at our facilities, your team lead will make it happen. Unmatched Resources for Customization and Efficiency Elbex offers a wide range of resources to help your project succeed. Our in-house custom tool and die design services lower costs and allow us to provide turnaround times of days, rather than weeks. Our experts will help you select the right materials to ensure proper performance for your specific application and environment. We also provide a variety of technical resources (as well as the expertise of our own team) to fine-tune new designs or troubleshoot issues. The Elbex Advantage: Why Tailored Solutions Excel Custom solutions always deliver better results than standard designs. With Elbex, you get precision and performance that are optimized for your application. We seek to be a proactive partner who will help you address design challenges, while also guaranteeing a high level of quality with our hands-on approach. This fully integrated in-house approach ultimately saves you time and money – even as you get better results. With our team’s unwavering commitment to designing custom rubber extrusion profiles for specific applications and our ability to deliver customized extrusion solutions, you can count on Elbex to provide the components you need.

Thermal expansion, contraction, and vibration are persistent challenges in industrial and architectural structures. Left unchecked, these forces can cause significant structural damage – but rubber expansion joints can help. Custom-engineered extruded rubber expansion joints by Elbex offer superior performance and reliability to protect your structures. Understanding Extruded Rubber Expansion Joints Expansion joints play a vital role by reducing movement and vibration, as well as relieving stress caused by surface expansion or contraction. Rubber extrusions absorb movement to dampen vibrations and prevent damage to pipes, building materials, and other surfaces. The end result is greater stability and protection for the entire system. By forcing uncured rubber through a die and curing it in a 400°F salt bath, we can create fully cured, cross-linked, and durable extrusion profiles that address these needs in a variety of applications. Diverse Applications Across Industries Rubber expansion joints are used across many industries and applications, but they are most common in manufacturing and construction. In manufacturing, rubber expansion joints are used in transitions between two surfaces (such as in industrial piping systems), specialized uses like outgassing expansion joints in clean room ductwork, and more. In construction, movement joints provide structural stress relief and maintain structural integrity. These expansion joints keep structures in place while allowing necessary movement from natural expansion or contraction or even seismic activity. This improves the longevity of building materials and helps prevent damage that might otherwise occur. The Elbex Advantage: Customization and Comprehensive Support Working with Elbex for your rubber expansion joints provides several important benefits. Our design and engineering team brings decades of experience, allowing us to custom-design extrusions for any need. Our value-added services such as printing, cutting, splicing, taping, on-site silicone mixing and color matching, and in-house die tooling allow us to provide a rapid turnaround while meeting your precise specifications. Our team can also assist you with technical resources, design assistance, and even material selection to ensure the design and composition of your rubber expansion joint will deliver the performance you need. Our commitment to quality from start to finish will let you move forward with confidence. Elbex is your premier partner for designing and manufacturing custom rubber expansion joints that will safeguard your structures and systems from movement, vibration, and thermal change.
