Understanding Custom Extruded Rubber
Custom extruded rubber involves shaping rubber compounds into precise profiles using extrusion machines. The process forces the material through a custom-designed die, creating consistent shapes and dimensions. This method is highly versatile, enabling the production of a vast array of rubber parts. The resulting products are used extensively in various sectors, including automotive, aerospace, and construction. Wuxi Aomeite Seal Technology Co.Ltd (rubberextrusionmolding.com) highlights the versatility of this approach.
Key Technical Features
The performance of custom extruded rubber hinges on several critical technical features. These features vary depending on the intended application and the chosen rubber compound. Manufacturers like Jinyuan Rubber (jinyuanrubber.com) emphasize quality and adherence to industry standards.
| Feature | Description | Importance |
|---|---|---|
| Tensile Strength | Measures the rubber’s resistance to stretching and tearing. | Crucial for durability and longevity, especially in demanding applications. |
| Hardness (Shore A) | Indicates the rubber’s resistance to indentation. A higher Shore A value means harder rubber. | Affects the seal’s compression set and resistance to wear. |
| Elongation at Break | Percentage of stretching before breaking. | Determines flexibility and resilience. |
| Tear Strength | Resistance to tearing propagation. | Important for applications subject to impact or abrasion. |
| Temperature Resistance | Range of temperatures the rubber can withstand without significant degradation. | Ensures reliable performance across varying environmental conditions. |
| Chemical Resistance | Ability to withstand exposure to specific chemicals without deterioration. | Essential for applications involving contact with oils, fuels, or other chemicals. |
| Compression Set | Percentage of permanent deformation after compression. | Indicates the rubber’s ability to maintain its shape and sealing properties under sustained pressure. |
Types of Custom Extruded Rubber
Custom extruded rubber is available in several forms, each suited to different applications. The choice depends on factors such as the required flexibility, strength, and sealing characteristics.
| Type | Description | Advantages | Disadvantages |
|---|---|---|---|
| Solid Rubber Extrusions | Continuous, solid rubber profiles. | High strength, good abrasion resistance. | Less flexible than other types. |
| Sponge Rubber Extrusions | Porous rubber with air cells, providing cushioning and sealing properties. | Good cushioning, lightweight, good sealing. | Lower strength than solid rubber. |
| Co-extruded Rubber | Combines two or more rubber materials with different properties in a single profile. | Enhanced properties like improved sealing and durability. | More complex manufacturing process. |
| Cellular Rubber | Rubber with closed-cell structure, providing insulation and sealing. | Excellent insulation, lightweight, good sealing. | Lower strength than solid rubber. |
| Dual Durometer Extrusions | Combines rubber materials of different hardnesses in a single profile. | Customized hardness for different sections, improving functionality. | More complex manufacturing process. |
