1 avr. 2000 · A grooved feed section improves solids conveying and increases extruder pumping action, thereby raising output at a given extruder rpm, reducing energy put into the polymer, and lowering melt temperature.
22 févr. 2015 · Extruders with grooved feed throats resist rotation of the solid polymer particles against the feed-throat wall. This can increase conveying efficiency multiple times.
29 nov. 2021 · When it comes to HDPE product applications such as pipe extrusion, we have found that groove feed extruders offer significant advantages over smooth bore extruders. These benefits include increased output, reduced melt temperature, improved mixing quality, and linear consistency.
Groove feed technology for pipe and profile applications. Extruders available in sizes from 2 to 6 inches (50 to 150mm) in 42:1 L/D sizes. Advanced spiral groove feed section designed for processing HDPE, PP and other thermoplastic resins. Advantages. 40-70% higher output rate at lower processing temperatures.
The SHO groove feed extruder is built for today’s high-performance, environmentally conscious marketplace. Based on Davis-Standard’s popular Thermatic® design, this model delivers greater throughput, lower melt temperatures and consistent product quality.
20 févr. 2012 · A grooved-feed extruder builds pressure in the rear of the screw, or directly in front of the groove bushing area. This area is typically the high-pressure area along the length of the screw, where resin is actually being pushed through the screw.
1 juil. 1998 · Grooved feed single screw extruders—improving productivity and reducing viscous heating effects. Owing to their high productivity, pressure invariance, and controlled throughput and melt temperature, groove feed systems are becoming widely accepted for the extrusion of pipes, blown films, and blow molded articles.
