Success Stories & Trust
05
A Vietnamese customer purchased HSCI-T-1000 (4+4 configuration) for high-quality cement bag printing. Before HAOSEN, they used old inline printers with poor registration and frequent downtime. After installation with HAOSEN engineer on-site for 2 weeks, they now run at 280 m/min with ±0.3mm registration accuracy. "The 4+4 configuration allows us to print 6 colors on front + 2 colors on back in one pass — we eliminated a second printing line," said the production manager.
-- Southeast Asia Cement Bag Factory (Vietnam)
A Saudi customer needed a high-speed CI flexo press for paper-plastic laminated bags. HAOSEN recommended HSCI-T-1200 with dual-station non-stop unwind/rewind. Production started within 90 days. The non-stop roll change feature increased their daily output by 25%. The customer appreciated that HAOSEN handled all technical coordination — they only talked to one team.
-- Middle East Paper-Plastic Bag Manufacturer (Saudi Arabia)
"We were looking for a high-speed, high-precision CI flexo press for our woven bag line. Many suppliers offered narrow machines with limited color capacity. HAOSEN provided the HSCI-T-1200 with 4+4 configuration — 1200mm width, 8 colors, 300 m/min printing speed. The engineer stayed 2 weeks and trained our 8 operators. Now we produce 100,000 bags per shift with consistent quality." — Indonesia customer, woven bag manufacturer
