3. Manufacturing Process — Dual Drum Winch Flowchart & Standards

Advanced dual drum winch manufacturing integrates robust materials, precise machining, and rigorous testing to ensure performance and compliance:

Material Selection: Forged alloy steel (ASTM A572/EN S355) for drum core, stainless steel (316/2205 Duplex) for rope grooves—guarantees impact resistance and anti-corrosion.
Drum Casting: Automated sand casting for uniform grain and high load capacity. Drum surface hardness > 280HB.
CNC Machining: High-precision shaft/drum machining (tolerances within ±0.02mm); digital balance adjustment for concentricity.
Welding & Assembly: Submerged arc welding (SAW) for structural joints. ISO 3834 certified procedures for quality.
Anti-Corrosion Treatment: Marine epoxy primer (DFT≥350μm) + polyurethane finish; salt spray resistance per ISO 9227 (≥1200h).
Inspection & Testing: Drum proof load (1.25x rated), NDT ultrasonic/MPI checks, rope groove laser measurement.
Electrical/Hydraulic Integration: Enclosed controls (IP65+), ISO-certified variable speed drives or hydraulic valves.
