During this stage, the selected materials are compounded with various additives to enhance their properties, such as heat resistance, UV stability, and flexibility. This compounding process is critical, as the right mixture will determine the seal’s performance in its intended application.

2. Forming

Once the material is prepared, the extrusion process begins. The rubber compound is heated and then forced through a die, which shapes it into the desired profile. Key techniques used in this stage include:

• Single Extrusion: The most common method, producing a continuous profile of uniform shape.
• Co-Extrusion: Involves using two or more materials in a single extrusion process to achieve multi-material seals that combine the properties of different rubbers.
• Pultrusion: Although less common for seals, this technique can be used for profiles requiring reinforced structures.

Precision is critical during this phase. The dimensions of the extruded seal must adhere to strict tolerances to ensure proper fitting and sealing performance in the final application.

3. Assembly

After forming, seals may undergo additional assembly processes. This can include:

• Cutting: To achieve the required lengths.
• Splicing: Joining ends of the extruded seals for continuous applications.
• Adhesive Application: Adding adhesives to enhance bonding capabilities in specific applications.

These steps are designed to prepare the seals for their intended use, ensuring that they meet the performance specifications required by the end-user.

4. Finishing

The final stage involves surface treatment and quality checks. This may include:
