PVC foaming sheet extrusion line is a type of production line that is used to manufacture PVC foam sheets. PVC foam sheets are lightweight, durable, and have excellent thermal insulation properties. They are used in a wide range of applications, such as advertising boards, construction materials, and automotive interiors.
The extrusion line consists of several key components, including a twin-screw extruder, a T-die, a calibration table, a cooling system, a haul-off unit, and a cutting machine. The twin-screw extruder is the heart of the extrusion line, where the PVC foam material is melted, mixed, and extruded through the T-die to form a flat sheet.
The T-die is responsible for shaping the extruded material into a uniform thickness and width.
The calibration table is used to cool and solidify the extruded material, while the cooling system helps to maintain a constant temperature throughout the production process.
