Key Equipment Features
- Rapid roller adjustment capability significantly reduces changeover time between products, improving efficiency and reducing production costs
- Utilizes a combined mold system that produces different tube specifications through adjustment rather than replacement, achieving over 90% roller savings
- Motorized adjustments minimize tool input and equipment damage during roll changes, extending equipment service life
- Composite roll structure creates point contact (rather than line contact) between roll and strip, reducing wear and extending roll life

Production Process
Raw material (strip) → loading car → uncoiler → cutting and welding → feeding → storage material → passive leveling → forming rolling → high frequency welding → weld burr removal → cooling → sizing → coarse straightening → length cut → collection
Production and Payment Terms
Production Period: 8 months after signing contract
Payment Terms: 30% TT as downpayment after signing contract, 70% TT payoff before delivery
All square and rectangular tube specifications use a set of rollers, requiring no replacement - adjustments are made by motor.
