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.
