3. Rubber Lining Production:
   • Compounding & Extrusion: Raw rubber polymers are blended with various additives to achieve desired properties (e.g., hardness, elasticity, chemical resistance). This compound is then extruded into precisely dimensioned sleeves or profiles for the hose clamp rubber lined element.
   • Vulcanization: The extruded rubber is subjected to heat and pressure, a process known as vulcanization, to cross-link the polymer chains. This significantly improves the rubber's strength, elasticity, and resistance to deformation and temperature.
4. Assembly: The manufactured metal components and the vulcanized rubber lining are carefully assembled. For Type A couplings, the rubber sleeve is integrated within the stainless steel bands, ensuring a perfect fit and seal. Specialized tooling ensures proper alignment and tensioning.
5. Testing and Quality Assurance: Every batch undergoes rigorous testing to meet international standards.
   • Hydrostatic Pressure Testing: Clamps are tested under high pressure to verify leak-proof integrity.
   • Torque Testing: Screws and bands are tested for optimal torque specifications, ensuring secure fastening without stripping or material fatigue.
   • Corrosion Resistance: Salt spray tests assess the durability of stainless steel components against corrosive agents, vital for a rubber hose clamp.
   • Material Hardness & Tensile Strength: Rubber and metal components are tested for their mechanical properties to confirm adherence to specifications.
6. Certifications: Products are manufactured under strict quality management systems, often certified to ISO 9001. Performance compliance with standards like ASTM A240 for stainless steel, ASTM D2000 for rubber materials, and local plumbing codes (e.g., ANSI/ASME) is verified.

The robust design and manufacturing precision contribute to a significantly extended service life, often exceeding 20 years in typical applications, reducing the total cost of ownership for industrial clients.
