Customers Feedback

🇻🇳 Case 1: Vietnam ERW Tube Mill

To improve production efficiency, the client introduced our Double-Head 4 Ton Uncoiler with a PLC automatic control system.
The coil loading and changeover time was reduced from 3 minutes to less than 1 minute, effectively cutting downtime caused by coil replacement by over 40%.

"This double-head uncoiler truly enabled non-stop coil change, significantly boosting our production capacity. Very stable performance." — Technical Director

🇷🇺 Case 2: Russia Roll Forming Line

This customer integrated our Double-Head 4 Ton Hydraulic Uncoiler into their Z-shaped cold roll forming line.
The machine ensured continuous feeding and heavy-duty decoiling performance, even in extremely low temperatures down to -20°C, meeting the harsh operation conditions in Russia.

"The machine runs stably. The hydraulic expansion and coil switching system are very user-friendly and greatly reduced manual work."
