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.
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.
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.
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.
grooved feed extruders not only the transport capabilities, reflected in higher productivity, were improved, but also the grooved feed systems showed higher melt flow stability and pressure invariance.
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.
These high-performance extruders are based on Davis-Standard’s popular Thermatic® design. Davis-Standard has made significant advancements in groove feed bushing design and barrier screw design to enable processing high-output low-melt temperature, improved mixing and homogenization, and linear output.
