Engineering Plastic Extrusion Line

A: The products this kind of equipment can manufacture include pipes, profiles, sheets, films, and WPC (Wood Plastic Composite) materials. A very common use for the machines is the production of PVC pipes, HDPE sheets, blown films for making packages, and other industries that need custom shaped plastic parts.

 A: An engineering plastic extrusion line features eight essential working parts which are; 1. An extruder, single screw or twin screw 2. A die and a diehead 3. A sizing or calibration machine 4. Cooling equipment 5. A haul off unit 6. A cutting or sawing machinery 7. Built-in extras for processing or packaging. Q:Distinguish between a single screw type of an extruder and the twin screw. A: The single screw types are more economical in terms of usage because only one rotating helical screw is used for transporting, melting and applying pressure on the granules of plastics. They are easier and cheaper for many applications. Two Twin screw extruders cable to intermesh and have two screws that provide better mixing potentials, higher outputs and greater control over the distribution of the material in the extrusion process. They are ideal in applications requiring more complex formulations or higher throughput.

A: Pipes and other singular cylindrical products are turned into a desired shape via a single barrel on a pipe extrusion line. In contrast, profile extrusion lines usually come with a maximum of five synchronized screws. The cylindrical pieces have been replaced with specialized barrels containing multiple screws during the mounting process.

A: Downstream equipment is essential for ensuring the final quality and features of the extruded part that includes the cooling tanks, haul-off units, cutting machines and packaging units. These components undertake correct cooling, appropriate sizing and proficient finishing of the extruded products which influences the productivity and durability of the production line and the end product.

A: Besano and Leistritz are well known in the market as producers of extrusion machinery and providers of turnkey extrusion lines. They specialize in a wide range of markets through their production of extruders and extrusion lines which include special extrusion lines for several niches. Such companies enhance the production of plastics by expanding the boundaries of plastic extrusion processes through design innovation, and providing production equipment manufacturing and engineering solution services to address the customers’ requirements.

A: Some recent advancements in plastic extrusion line include: 1. Reduction in the cost-to-power ratio 2. Enhanced measurement and control systems for the processes 3. Smart industry technologies 4. Novel components designed for extruder machines 5. More advanced levels of profile complexity in dye design 6. Advanced equipment for downstream processes to improve the overall quality of the end product along with better throughput

A: A few pointers: 1. Manage and service the extrusion equipment properly assuring cleanliness 2. Adequate screw and dies for said product and material 3. Apply process and machine controls 4. Introduce operators to the practices in troubleshooting 5. Ensure all raw and compound materials are of warrantable quality 6. Synchronization of downstream equipment avant-garde adjustment 7. Undertake R&D in extrusion processes and product invention
