Universal Main Unit, Modular Switching<\/h2>\n\n\n\n<p>The Hartek desktop extrusion main unit (16mm single screw) adopts a modular design: quick-change connectors support different dies and downstream equipment.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>+Hanger Die + Casting Unit + Rewinding \u2192 Cast Film Experimental Line<\/li>\n\n\n\n<li>+Blown Film Die + Traction + Rewinding \u2192 Laboratory Blown Film Machine<\/li>\n\n\n\n<li>+Sheet Die + Three-Roll Calender \u2192 Three-Roll Calender Sheet Experimental Line<\/li>\n\n\n\n<li>+Granulation Die + Pelletizer \u2192 Twin-Screw Extrusion Granulation Experimental Line<\/li>\n\n\n\n<li>+Wire Die + Cooling Water Tank + Traction + Winding \u2192 3D Printing Consumables Experimental Line<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">II. Real-World Case Studies from R&amp;D Users<\/h2>\n\n\n\n<p>A modification company: Using the same main unit, casting film formulation screening is done on Mondays, blown film comparison is done on Wednesdays with a different die, and wire verification is done on Fridays. One machine completes small-scale trials of three products.<\/p>\n\n\n\n<p>A university research group: Equipped with one HAER main unit + multiple functional modules, it supports three graduate students with different research directions (biodegradable films, conductive sheets, and medical consumable filaments, respectively).<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"> III. Advantages of <a href=\"https:\/\/extruder-lab.com\/es\/products\/desktop-film-extruder-line\/\">Desktop Extruder<\/a><\/h2>\n\n\n\n<p>Small footprint: A modular main unit + functional units occupy less than 2 square meters.<br>Controllable cost: Only the main unit and basic modules need to be purchased; additional units can be purchased as needed.<br>Unified operation: A consistent control system interface reduces learning costs.<br>Consistent data: Experimental data from different processes are recorded on the same platform, facilitating horizontal comparison.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">IV. Applicable Scenarios<\/h2>\n\n\n\n<p>University materials laboratories: One device supports multiple experimental courses.<\/p>\n\n\n\n<p>Enterprise R&amp;D centers: Quickly switch between small-scale testing needs of different product lines.<\/p>\n\n\n\n<p>Public testing platforms\/pilot plant bases: Provide customers with various process processing services.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">V.
