Custom Rubber Extrusion
Custom rubber extrusion is a manufacturing process used to produce continuous rubber profiles with a fixed cross-sectional shape. It is widely applied in door and window systems, construction, automotive, industrial equipment, and electrical enclosures where reliable sealing, insulation, and protection are required.
Flexnite provides professional custom rubber extrusion services, supporting OEM and ODM projects. Based on customer drawings, samples, or application requirements, we develop suitable rubber compounds and extrusion tooling to ensure stable dimensions, consistent quality, and long-term performance.
Product Features
Manufactured using high-quality rubber compounds for stable performance
Excellent flexibility and elasticity for tight and reliable sealing
Strong resistance to aging, UV, ozone, and weather conditions
Smooth surface finish and accurate cross-section tolerance
Suitable for long-term indoor and outdoor use
Custom rubber extrusion profiles can be produced as solid rubber, hollow rubber, sponge rubber, or composite structures according to different sealing requirements.

FAQ - Custom Rubber Extrusion
Q1: What is custom rubber extrusion?
A1: Custom rubber extrusion is a manufacturing process in which uncured rubber is forced through a die to create continuous rubber profiles with specific cross-sectional shapes. These profiles are then vulcanized to achieve the required strength, flexibility, and durability.
Q2: What types of rubber materials can be used for custom extrusion?
A2: We offer a wide range of rubber materials for custom extrusion, including EPDM, Silicone, Nitrile (NBR), Neoprene (CR), PVC, and TPV/TPE. Each material has different properties, such as temperature resistance, UV resistance, and mechanical strength, allowing us to tailor the rubber to your specific application.
Q3: How do I choose the right rubber material for my application?
A3: The selection of material depends on factors such as:
Temperature range (e.g., EPDM for high heat, Silicone for extreme temperatures)
Environmental exposure (e.g., UV, ozone, or chemicals)
Mechanical properties (e.g., strength, elasticity, and abrasion resistance)
Our experts are available to help guide you through the selection process based on your requirements.
Q4: What are the standard sizes for custom rubber extrusion profiles?
A4: We can create rubber extrusions in virtually any size and shape, based on your specifications. Our team can produce profiles ranging from small sealing strips to larger components, and we can adjust the dimensions as needed to fit your application.
Q5: How do you ensure the quality of custom rubber extrusions?
A5: Quality is a key priority in our custom rubber extrusion process. We follow strict quality control standards, including:
Material testing to verify compound properties
Dimensional inspection to ensure profile accuracy
Post-production testing for elasticity, tensile strength, and compression resistance
All products are inspected before shipment to guarantee they meet the required specifications.
Q6: How long does it take to produce custom rubber extrusions?
A6: The production time for custom rubber extrusions depends on the complexity of the profile and order quantity. Typically, sample production takes 7-10 business days, and mass production usually takes 2-4 weeks. We can provide a more specific timeline based on your project's requirements.
Q7: Do you offer small batch production for custom rubber extrusions?
A7: Yes, we support both small batch and large-scale production. Whether you need a few samples for testing or a larger volume for full-scale manufacturing, we can accommodate your needs and adjust production runs accordingly.
Q8: Can you provide custom colors for rubber extrusions?
A8: Yes, we offer custom color options for most of our rubber extrusion products. Whether you need a specific color for branding purposes or for aesthetic reasons, we can match the color to your specifications.
Q9: Are custom rubber extrusions suitable for outdoor use?
A9: Absolutely! Many of our custom rubber extrusions, especially those made from materials like EPDM and Silicone, are designed to withstand outdoor conditions, including extreme temperatures, UV exposure, and ozone. They are ideal for use in building facades, automotive seals, and other outdoor applications.
Q10: How can I place an order for custom rubber extrusions?
A10: To place an order, simply send us your product requirements, including drawings or samples of the rubber profile you need. Our team will review your request, provide a quote, and assist with any customization options. Contact us at sales@flexmer.com to get started.
