A mill cuts pockets and external shapes, a lathe produces round features, and a router cuts profiles and openings in sheet.<\/p><p>This route uses stock material rather than a mold. It suits functional prototypes, replacement parts and production components when the required resin is available in a machinable form.<\/p><p>The drawing remains essential: a CAD model describes shape, but does not always define critical fits, datum references, threads, surface appearance or inspection conditions. Supply both when these details determine whether the part will work.<\/p><p>For plastic parts, the finished dimensions also depend on temperature, moisture, clamping and residual stress. Material selection and the machining sequence need to account for these effects, particularly on thin walls and close-fitting assemblies.<\/p><a class=\"pp-back\" href=\"#plastic-guide-contents\">Back to contents \u2191<\/a><\/div>\n<\/div><\/section>\n<section aria-labelledby=\"plastic-gallery\" class=\"pp-section pp-gallery-section\"><div class=\"pp-wrap pp-gallery-layout\"><div class=\"pp-gallery-intro\"><h2 id=\"plastic-gallery\">Plastic Part Examples<\/h2><p>Explore the shapes that machining can produce: clear housings, threaded parts, detailed manifolds and components with features on several faces.<\/p><p>Use these geometries as a starting point for discussing your own design.
