Plastic sheet and plate (vacuum) extruder single screw and barrel

The sheet venting screw is a key component used in sheet production during extrusion or injection molding. Its design features a special structure (such as a dual venting section) to remove gas and moisture from the raw material, improving sheet quality and simplifying the process. The following are relevant technical points and application information:

I. Structural Design

• Dual-venting screw: Designed specifically for materials such as polycarbonate, it comprises a feed section, compression section, mixing section, and dual venting section. The venting section features deeper screw grooves and a finer flight pitch, effectively removing moisture and eliminating the traditional drying step.
• Aspect Ratio: Typically 30-42:1, ensuring adequate melting and venting.

II. Applications

◆ PE sheet. PE sheet. PP sheet. PP sheet. PVC sheets, PVC sheets, etc. (packaging, chemicals, electricity, engineering, machinery)
◆ PS foam boards, PS boards, ABS boards, etc. (insulation boards, decoration, home appliance shelves, luggage, toys, electronic product consumables)
◆ PMMA sheets, PC sheets, PETG sheets, etc. (chemicals, culture and education, automotive, shipbuilding, aircraft manufacturing; optical lighting, etc.)
◆ Large lampshades, explosion-proof lamps, automotive and aircraft window glass
◆ PA sheets, PEEK sheets, PTFE sheets, PVDF sheets
