Professional PVC Flexible Door Curtain Production Line Solutions Enable Efficient Industrial Door Curtain Production

We continuously provide professional PVC flexible door curtain production line solutions for the industrial sector. This mature equipment is specifically designed for producing PVC flexible door curtains in various widths, including 200mm, 300mm, and 400mm. The PVC flexible door curtain equipment uses an SJ90×33 single-screw extruder as its core, equipped with multiple coat hanger-type sheet molds, achieving a stable output of 100-180kg/h. This PVC flexible door curtain production line, proven in the market for a long time, continues to provide reliable door curtain material production equipment for the industrial sector.

The core extrusion system of this PVC flexible door curtain production line adopts a single-screw design with a screw diameter of 90mm and a length-to-diameter ratio of 33:1, specifically optimized for the characteristics of PVC raw materials. The extruder is equipped with a 6-zone heating system with a heating power of 24KW, using cast aluminum heating coils and fan cooling. The main motor is a 37KW AC motor, with precise speed regulation achieved through a Weichuang frequency converter. The screws and barrels of the PVC flexible curtain equipment are made of 38CrMoAIA material, with a nitriding depth of 0.4-0.7mm to ensure wear resistance and service life.

The mold system of the PVC flexible curtain production line adopts a coat hanger-style gradient flow channel design, equipped with three sets of molds: 200mm, 300mm, and 400mm, with effective mold widths of 240mm, 350mm, and 450mm respectively. The molds are equipped with a 3-zone heating system, with heating power configured from 9-15KW depending on the specifications. The vertical three-roll calender is equipped with ∮320×800mm mirror rollers, with a roller hardness of RC60-65, and the molding temperature is precisely controlled by a softened water constant temperature system. These mature configurations ensure that the products produced by the PVC flexible curtain equipment have stable transparency and flexibility.

The entire PVC flexible curtain production line also includes a 5-meter stainless steel cooling bracket, a rubber roller traction machine, and a dual-station winding system. The traction machine is equipped with a ∮220×800mm special rubber roller, and its speed is linked to the calender via a 1.5KW frequency converter. The winding system adopts a dual-station design with a maximum winding diameter of 400mm, enabling continuous production. The electrical control system of the PVC flexible door curtain production line uses high-quality components such as Siemens contactors and Omron temperature controllers to ensure long-term stable operation.

We have equipped the PVC flexible door curtain equipment with a complete raw material processing system, including a spiral feeder and a hot air dryer. The total power of the entire production line is 90KW, with installation dimensions of 16.4×2.5×2.5 meters, suitable for most production workshop layouts. The PVC flexible door curtain production line is also equipped with striped matte rollers, which can produce flexible door curtain products with different surface effects according to customer needs.

This PVC flexible door curtain production line adopts a modular design, making operation and maintenance simple. We provide continuous technical support services for the PVC flexible door curtain equipment, including installation guidance, operation training, and after-sales maintenance, ensuring that customers can operate the production line stably for a long time. The ease of operation of the equipment allows manufacturers to quickly train operators and put the equipment into normal production as soon as possible.
