Concial Twin Screw Plastic Pvc Pipe Lines UPVC Extruders Machines Conical twin-screw extruder is composed of barrel, screw ,gear transimission system,measurable feeding,vacuum system,heating,cooling and electronic control components. It is mainly used in plasticizing,extruding and forming PVC pipe ,plate,sheet,film,profile,and granule,etc Conical twin screws are commonly used in the WPC (Wood Plastic Composite), PVC (Polyvinyl Chloride), and PE (Polyethylene) industries for extrusion processes. They are specifically designed to meet the requirements of these industries and are used in extruder machines. Extruder screws and barrels are essential components of an extrusion system. The screw is responsible for melting and conveying the polymer material, while the barrel provides the necessary heat and pressure for the extrusion process. Conical twin screws and barrels are designed with a tapered shape that allows for efficient mixing and melting of the polymer materials. Here are some key features and benefits of conical twin screws and barrels for the WPC, PVC, and PE industries: Mixing Capability: Conical twin screws are designed to provide excellent mixing of the polymer materials, ensuring uniform distribution of additives, fillers, and wood fibers in WPC extrusion. This leads to improved product quality and consistency. Melting Efficiency: The tapered design of conical twin screws allows for increased surface area during the melting process. This results in better heat transfer and faster melting of the polymer materials, reducing energy consumption and improving productivity. Self-Cleaning: Conical twin screws have a self-wiping mechanism, which helps in reducing material buildup and minimizing the risk of cross-contamination, especially when switching between different materials or colors. Higher Throughput: The design of conical twin screws enables higher throughput rates compared to other types of screws. This is beneficial for industries requiring high production volumes. Versatility: Conical twin screws can process a wide range of materials, including rigid and flexible PVC, various types of polyethylene (HDPE, LDPE, LLDPE), and WPC compounds. This makes them suitable for different applications within the WPC, PVC, and PE industries.
