What Are Semi-Finished Tubes for Seal Making?

Seals are crucial in mechanical systems, preventing leaks, reducing friction, and ensuring efficiency. These are made from semi-finished tubes, which serve as raw materials for machining, cutting, or molding processes.

 

Read on and explore what semi-finished tubes are, their advantages, materials, and applications in seal manufacturing.

 

Understanding Semi-Finished Tubes

Semi-finished tubes are cylindrical raw materials made from elastomers, thermoplastics, or other sealing materials. They are designed for further processing into finished seals, such as O-Rings, Gaskets, and Hydraulic Seals, using precision machining techniques like CNC turning or milling.

 

How Are Semi-Finished Tubes Different? 

Pre-Formed Structure: Available in various diameters, thicknesses, and materials to cater to specific sealing requirements.

Enhanced Machinability: Manufactured into custom seals for easy processing.

Consistent Quality: Ensure uniform material composition and mechanical properties for reliable sealing performance.

Time-Saving: Eliminates the need for extensive molding or extrusion, allowing rapid production of seals.

 

Benefits of Using Semi-Finished Tubes for Seal Making

 

1. Customization For Specific Applications
   Semi-finished tubes serve as raw materials for high-quality seals, customizable to industry needs and capable of withstanding extreme temperatures, high pressures, and harsh chemicals.

 

2. Reduced Lead Time and Costs
   Using pre-formed semi-finished tubes can significantly minimize production time and reduce the costs of the manufacturing processes.

 

3. Improved Material Efficiency
   Machining seals directly from semi-finished tubes reduces material waste and enhances machine performance.

 

4. Higher Precision and Performance
   Semi-finished tubes provide superior uniformity, thereby enabling tight tolerances and high performance of seals in critical applications.

 

5. Versatility Across Industries
   From hydraulic systems to food processing equipment, semi-finished tubes cater to diverse industry needs due to their adaptability and range of material choices.

 

Materials Used In Semi-Finished Tubes

Semi-finished tubes are available in various materials, depending upon the requirements of the applications:

Elastomers (Rubber-Based Materials)

• Nitrile (NBR): Oil and fuel resistance.
• Fluoroelastomer (FKM/Viton): High chemical and temperature resistance.
• EPDM: Excellent weathering and ozone resistance.

Thermoplastics

• PTFE (Teflon): Low friction and superior chemical resistance.
• PEEK: High strength and temperature resistance.
• UHMWPE: Exceptional wear resistance.

Polyurethane

Highly durable and abrasion-resistant, which is ideal for dynamic sealing applications.
