Overview & Technical Specifications
01
This HSQF-800 high-speed cold cutting-sewing machine integrates cold cutting and sewing processes into a single efficient production line. Unlike hot cutting machines, the cold knife cutting produces no smoke, no smell, and no bag mouth adhesion — making it ideal for customers who prefer cold cutting or have environmental/worker health concerns. Key innovations include auto deviation correction for precise web alignment, color tracking servo control for precise bag length and delivery, robot arm stabilizer (Up/down simultaneous translation) for superior stability, and free conversion between front and back labels. Features include electric auto feeding, PLC centralized control with touchscreen data setting/display/recording/storage/call, frequency conversion speed adjustment for synchronized cutting/sewing speeds, automatic counting/bag folding/fixed displacement, and sewing machine automatic thread break alarm with shutdown. HAOSEN sources this machine from China's top bag-making equipment factories, verified for patent clearance and after-sales capability.
Notes on Suitable Ingredient： Woven bags, laminated woven bags, paper-plastic laminated bags (cold cutting is particularly suitable for heat-sensitive materials).

Success Stories & Trust
05
A Vietnamese cement bag manufacturer preferred cold cutting over hot cutting due to environmental regulations and worker health concerns. Their old hot cutter produced smoke that workers complained about. HAOSEN installed HSQF-800 with cold knife and auto deviation correction. "No smoke, no smell — workers are happy. The cold cuts are clean and bags open easily. The robot arm stabilizer keeps everything running smooth at 60 pcs/min," said the factory manager. The filling line rejection rate dropped from 7% to under 1%.
-- Southeast Asia Cement Bag Factory (Vietnam)
A Saudi customer needed a high-speed cut-sew machine for heat-sensitive laminated fabric that could not be hot cut. HAOSEN recommended HSQF-800 with cold knife, robot arm stabilizer, and auto deviation correction. Production started within 50 days. "Cold cutting is perfect for our heat-sensitive material — no melting, no burning. The auto deviation correction saves us from constant manual adjustment. The robot arm keeps everything stable," said the plant owner.
-- Middle East Fertilizer Bag Plant (Saudi Arabia)
"We tried hot cutting machines but had problems with smoke, smell, and sticky bag mouths. Workers complained, and our filling line was slow. HAOSEN's HSQF-800 with cold cutting solved everything. No smoke, no smell, no sticking — bags open perfectly every time. The color tracking servo gives us perfect bag length. The robot arm stabilizer makes it incredibly smooth. Best decision we made." — Indonesia customer, feed bag manufacturer
