EXTRUSION SCREWS WITH MULTIPLE CHANNELS
- 技术优势
- The technology has been deployed with full-scale validationon an instrumented extruder having a screw diameter of 38 mm and an output rateof 50 kg/hr. Processing and product quality data indicate competitiveadvantages including: Shorter screw designs, thereby reducing the size, cost, andcomplexity of machinery. Lower residence times,thereby reducing any degradation of the material properties.More efficient and uniformprocessing, avoiding the need for active cooling.Precise control of theprocessing history, to improve consistency and dispersion.Higher quality productionwith reduced machinery, processing, and energy costs.

None
- *Background
- Plasticating screws are used in virtually allplastics manufacturing processes, including extrusion, blow molding,thermoforming, and injection molding that convert the polymer resin to thefinished product. Moreover, extrusion is used not only in the conversion offeedstock to finished goods (tubing, sheet, film, profiles, etc.), but it isalso used in compounding, polymerization, and other processes for creation ofthe feedstock materials. Existing screw designs are deficient with respect tothe conveyance and melting of pelletized feedstock.
