3. Wholesale Suspension Clamp Manufacturing Process: Step-By-Step
Flowchart: Manufacturing of wholesale suspension clamp
Use of certified high-strength steel, aluminium alloy, with strict incoming quality control (ISO 9001, ASTM standards).
Employ closed-die forging or precision sand casting for primary clamp bodies, optimizing grain orientation for fatigue resistance.
Precision forming, drilling, and surface contouring via CNC. Galvanization/epoxy/Zn plating ensures ideal anti-corrosion layers per IEC/ISO standards.
Automated assembly with torque-controlled fittings. Each unit undergoes pull, fatigue, and corrosion testing (see data below).
Laser marking for traceability, export-grade packaging, delivery (lead time: 10–28 days typically).
4. Technical Advantages & Why Choose wholesale suspension clamp from Leading Suppliers?
- Exceptional Mechanical Strength: Tensile load up to 150kN. Suitable for high-voltage transmission lines.
- Corrosion and Environmental Resistance: Triple-layer Zn or epoxy coatings. Life expectancy: >30 years (per IEC 61284 accelerated salt spray tests).
