Success Stories & Trust
05
A Vietnamese cement bag manufacturer had persistent problems with hot cutting producing smoke and bag mouths sticking together. Workers complained about fumes, and the filling line rejected 8% of bags due to stuck mouths. HAOSEN installed HSRQF-800 with smokeless hot knife and auto deviation correction. "The smokeless knife eliminated all smoke — workers are happy. Bags open instantly, no sticking. Our filling line rejection rate dropped to 0.5%," said the factory manager. The robot arm stabilizer ensures smooth operation at 60 pcs/min.
-- Southeast Asia Cement Bag Factory (Vietnam)
A Saudi customer needed a high-speed cut-sew machine with superior stability for heavy fertilizer bags. HAOSEN recommended HSRQF-800 with robot arm stabilizer and auto deviation correction. Production started within 50 days. "The auto deviation correction saves us from constant manual adjustment. The robot arm keeps everything stable even at maximum speed. The auto thread break alarm saved us from shipping defective bags," said the plant owner.
-- Middle East Fertilizer Bag Plant (Saudi Arabia)
"We were using an old hot cutter that produced smoke and sticky bag mouths. Workers hated it, and our filling line was slow. HAOSEN's HSRQF-800 changed everything. No smoke, no sticking — bags open perfectly every time. The auto deviation correction and robot arm stabilizer make it run incredibly smooth. The color tracking servo gives us perfect bag length. Best machine we ever bought." — Indonesia customer, feed bag manufacturer
