By cutting the extruded polymer melt strands directly at the die plate surface submerged beneath a circulating high-flow process water chamber, the system instantly quenches the cut molten droplets into perfectly uniform, dust-free spherical pellets without strand wrapping or airborne fumes.<\/p>\n<p>Equipped with an electrically or liquid-heated precision die plate, hydraulic quick-clamping cutting chamber, servo\/inverter-driven cutting shaft with micro-precision blade advancement, and an integrated tempered water loop (water tank, heat exchanger, and circulation pump), the underwater pelletizer operates continuously without operator intervention. Pellets are immediately swept into the slurry water pipeline and transferred directly to the centrifugal dewatering dryer, eliminating strand dropouts and labor-intensive line re-stringing.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Submerged die-face underwater pelletizing system for high-output, dust-free spherical pellet production of TPU, TPE, hot melts, and engineering plastics.<\/p>\n","protected":false},"featured_media":0,"template":"","equipment_category":[36],"process_stage":[43],"material_family":[131,133,129,95,132,92,89],"material_form":[75],"production_problem":[116,108],"class_list":["post-224","equipment","type-equipment","status-publish","hentry","equipment_category-pelletizing-auxiliaries","process_stage-pelletizing","material_family-modified-plastics","material_family-multifunctional-masterbatch","material_family-resin","material_family-rubber","material_family-thermoplastic-elastomer","material_family-tpe","material_family-tpu","material_form-pellets","production_problem-off-spec-pellet-size-and-fines","production_problem-sticking-and-agglomeration"],"_links":{"self":[{"href":"https:\/\/polypelletizer.com\/wp-json\/wp\/v2\/equipment\/224","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/polypelletizer.com\/wp-json\/wp\/v2\/equipment"}],"about":[{"href":"https:\/\/polypelletizer.com\/wp-json\/wp\/v2\/types\/equipment"}],"wp:attachment":[{"href":"https:\/\/polypelletizer.com\/wp-json\/wp\/v2\/media?parent=224"}],"wp:term":[{"taxonomy":"equipment_category","embeddable":true,"href":"https:\/\/polypelletizer.com\/wp-json\/wp\/v2\/equipment_category?post=224"},{"taxonomy":"process_stage","embeddable":true,"href":"https:\/\/polypelletizer.com\/wp-json\/wp\/v2\/process_stage?post=224"},{"taxonomy":"material_family","embeddable":true,"href":"https:\/\/polypelletizer.com\/wp-json\/wp\/v2\/material_family?post=224"},{"taxonomy":"material_form","embeddable":true,"href":"https:\/\/polypelletizer.com\/wp-json\/wp\/v2\/material_form?post=224"},{"taxonomy":"production_problem","embeddable":true,"href":"https:\/\/polypelletizer.com\/wp-json\/wp\/v2\/production_problem?post=224"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
