PP/PE Plastic Hollow Cross Section Plate Extrusion Line
A PP/PE Plastic Hollow Cross Section Plate Extrusion Line is a specialized mechanical system designed to manufacture polypropylene (PP) and polyethylene (PE) hollow-core panels. These production lines are widely used in industries such as packaging, construction, advertising, electronics, and pharmaceuticals due to their lightweight, high-strength, moisture-resistant, corrosion-resistant, and eco-friendly advantages, gradually replacing traditional cardboard and wooden packaging. Below is a detailed introduction to the PP/PE plastic hollow cross section plate extrusion line:
A PP/PE plastic hollow cross section plate extrusion line typically consists of the following main equipment:
Extruder: Equipped with specially designed screws and a temperature control system to ensure uniform plastic melting and stable high-output extrusion. Some models support degassing functions, making them suitable for recycled material processing.
Screen Changer: A hydraulic rapid screen-changing device improves efficiency, reduces downtime, and ensures continuous production .
Die: Made of high-quality alloy steel and equipped with a throttling device and differential adjustment system to ensure uniform sheet thickness .
Vacuum Calibration Table: Features a rapid heat-exchange cooling system combined with vacuum adsorption technology to stabilize the panel's shape.
Haul-Off Unit: Multi-roller synchronous drive ensures smooth sheet traction, with some models equipped with stress-relief devices.
Cutting Machine: Automatically cuts sheets to fixed lengths, improving production efficiency .
Control System: Uses PLC automation to regulate temperature, pressure, speed, and other parameters.
