Different molds can produce PVC sealing products in various shapes and sizes. These products are widely used for manufacturing sealing strips for PVC windows and doors, automobiles, shipping containers, electric vehicles, refrigerators, sterilization cabinets, and more. PVC Plastic Seal Strip Extruder: The PVC seal strip extruder is designed to manufacture sealing strips extensively used in car doors, windows, vehicle bodies, seats, sunroofs, engine compartments, and trunks. These strips play crucial roles such as waterproofing, sealing, sound insulation, dust prevention, frost resistance, shock absorption, heat retention, and energy conservation. The material must exhibit high tensile strength, good elasticity, as well as excellent temperature resistance and aging resistance. To ensure tight bonding between the seal strip and the profile, the cross-sectional dimensions of the seal strip must match those of the profile. The plastic seal strip production line is primarily used to manufacture automotive sealing strips, soft plastic strips, hard plastic strips, PVC window and door sealing strips, transparent soft-hard co-extruded water-stop strips, shower room sealing strips, soft-hard co-extruded water barriers for shower rooms, rubber strips for automobile windshield wipers, soft-hard co-extruded channel profiles, foldable double-layer price tags, dual-function price tags, and various other soft-hard co-extruded strips. Key Advantages: 1. Special barrel and screw design ensures high-speed extrusion and excellent plasticization. 2. Vacuum sizing and cooling guarantee precise roundness and uniform wall thickness. 3. Multi-V-belt traction system with stepless variable-frequency speed control and imported PU multi-V belts provides stable operation across different extrusion speeds. 4. Automatic reel changer enables continuous operation without downtime, rapid reel changes, and neatly arranged reels.

Applications and Features:

PVC plastic sealing strip production line and window/door sealing strip production line. This production line comprises a single-screw extruder, molds, a water tank, a traction unit, and a winder. By using different molds, it can produce PVC sealing products in various shapes and specifications. These products are widely used in the manufacture of sealing strips for uPVC windows and doors, automobiles, shipping containers, electric vehicles, refrigerators, sterilization cabinets, and more.

PVC plastic sealing strip extruder:

The PVC sealing strip extruder is used to produce sealing strips widely employed in door and window assemblies, vehicle bodies, seats, sunroofs, engine compartments, and trunk areas, providing critical functions such as waterproofing, sealing, sound insulation, dust resistance, freeze protection, vibration damping, thermal insulation, and energy efficiency. The material must exhibit high tensile strength, excellent elasticity, and superior temperature resistance and aging resistance. To ensure secure attachment between the sealing strip and the profile, the cross-sectional dimensions of the strip must be precisely matched to those of the profile.

The plastic extrusion line is primarily used to produce automotive sealing strips, flexible plastic strips, rigid plastic strips, PVC door and window sealing strips, PVC transparent soft‑and‑rigid co‑extruded water‑blocking strips, shower enclosure sealing strips, soft‑and‑rigid shower enclosure water barriers, wiper blades and wiper rubber strips for automobiles, soft‑and‑rigid co‑extruded cable channels, foldable double‑layer price tags, dual‑function price tags, and various other soft‑and‑rigid co‑extruded strips.

Advantage Description:

1. A specialized barrel design ensures high-speed extrusion and excellent plasticization.

2. Vacuum sizing and cooling ensure precise roundness and uniform wall thickness of the product.

3. Multi‑V‑belt traction unit, featuring stepless variable-frequency speed control and driven by an imported PU multi‑V belt. It ensures stable operation across a range of extrusion speeds.

4. Automatic palletizing machine with continuous operation and rapid, orderly pallet changes.
