The dosing method then narrows the machines that can host it. A premade-bag rotary platform doesn't matter if your product is a cohesive turmeric powder that won't flow through a volumetric cup; you need an auger filler, and the rotary platform has to be configured around it.<\/p>\n\n      <h3 class=\"sw-title-sub\">The right order:<\/h3>\n\n      <ol>\n        <li><strong>Classify your product:<\/strong> free-flowing granule \/ cohesive powder \/ sticky paste \/ fragile solid \/ thin liquid \/ viscous liquid.<\/li>\n        <li><strong>Pick the dosing method<\/strong> that handles that physics at the accuracy class you need (industrial \u00b11%, premium consumer \u00b10.5%; if you require \u00b10.2%, treat it as a regulated dosing project and ask for product-specific test data before any vendor commits).<\/li>\n        <li><strong>Then select the machine architecture<\/strong> that natively hosts that dosing method.<\/li>\n      <\/ol>\n\n      <p>If a sales engineer offers you a \"general-purpose machine\" before asking what your product is and how it flows, treat that as a flag.<\/p>\n    <\/div>\n  <\/section>\n\n<section class=\"sw-section sw-section-alt\" id=\"step1\">\n    <div class=\"sw-shell\">\n      <h2 class=\"sw-section-title\" style=\"text-align:left\">Step 1: Start with the Package Format, Not the Machine<\/h2>\n\n      <p>The first branch in the decision tree is the <strong>finished package<\/strong> your product needs to ship in.
