Different molds enable the production of various shapes and sizes of PVC sealing products, which are widely used in manufacturing sealing strips for plastic steel windows and doors, automobiles, shipping containers, electric vehicles, refrigerators, disinfection cabinets, and more. PVC plastic sealing strip production line, window and door sealing strip production line—comprising corresponding single-screw extruders, molds, water tanks, traction devices, and winding machines—designed to produce sealing strips for plastic steel windows and doors, automobiles, shipping containers, refrigerators, freezers, disinfection cabinets, and other applications. Key Advantages: 1. Optimized barrel and screw design ensures excellent extrusion and plasticization performance. 2. Vacuum sizing and cooling systems guarantee uniform roundness and consistent wall thickness of finished products. 3. Multi‑V‑belt traction system with stepless variable frequency drive and PU multi‑V belts provides stable operation across different extrusion speeds. 4. Automatic reel changer enables continuous operation without downtime, ensuring rapid reel changes and neatly arranged output. The screw and barrel have been optimized through CAD design, meeting diverse user requirements for different designs, formulations, and processing conditions. This machine stands out due to its improved stability, cost-effectiveness, and ease of maintenance compared to conventional extruders. All parts that come into contact with the material are cooled by circulating water, equipped with a constant-temperature water control system; selecting appropriate water temperatures helps maintain consistent quality of the extruded material. Additionally, pins installed within the barrel divide and redirect the flow of material moving along the screw, promoting better mixing between hot and cold layers while ensuring even heat distribution and high extrusion output. A digital speed-control system offers convenient operation. With a flexible and adaptable design framework, it can quickly accommodate customer-specific requirements. Equipped with various die heads, this machine can handle feeding, sheet extrusion, pipe extrusion, and extrusion of profiled materials, among other applications.
