Shut-off lands represent the mechanical contact faces where hardened mold steel clamps directly against the metallic insert surface.<\/p>\n<p style=\"font-size: 18px;line-height: 1.8em;text-align: left;margin-bottom: 24px\">Designing a flat sealing step measuring at least 0.5 mm wide along the insert shoulder creates a positive physical barrier against high-pressure melt leakage. Incorporating spring-loaded floating core pins compensates for dimensional tolerances in stamped metal inserts, maintaining tight shut-off contact without crushing the metal substrate.<\/p>\n<\/section>\n<p><!-- FAQ Section --><\/p>\n<section id=\"faq\" style=\"margin-bottom: 40px\">\n<h2 style=\"font-size: 28px;line-height: 1.5em;font-weight: bold;margin-top: 40px;margin-bottom: 24px;color: #111111;border-bottom: 1px solid #eaeaea;padding-bottom: 8px\">\u0427\u0430\u0441\u0442\u043e \u0437\u0430\u0434\u0430\u0432\u0430\u0435\u043c\u044b\u0435 \u0432\u043e\u043f\u0440\u043e\u0441\u044b (FAQ)<\/h2>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-3016\" src=\"https:\/\/www.jcinjectionmolding.com\/wp-content\/uploads\/2026\/08\/measuring-plastic-boss-wall-thickness.webp\" alt=\"measuring-plastic-boss-wall-thickness\" width=\"1376\" height=\"768\" srcset=\"https:\/\/www.jcinjectionmolding.com\/wp-content\/uploads\/2026\/08\/measuring-plastic-boss-wall-thickness.webp 1376w, https:\/\/www.jcinjectionmolding.com\/wp-content\/uploads\/2026\/08\/measuring-plastic-boss-wall-thickness-300x167.webp 300w, https:\/\/www.jcinjectionmolding.com\/wp-content\/uploads\/2026\/08\/measuring-plastic-boss-wall-thickness-1024x572.webp 1024w, https:\/\/www.jcinjectionmolding.com\/wp-content\/uploads\/2026\/08\/measuring-plastic-boss-wall-thickness-768x429.webp 768w, https:\/\/www.jcinjectionmolding.com\/wp-content\/uploads\/2026\/08\/measuring-plastic-boss-wall-thickness-18x10.webp 18w\" sizes=\"auto, (max-width: 1376px) 100vw, 1376px\" \/><\/p>\n<div style=\"margin-bottom: 30px\">\n<h3 style=\"font-size: 22px;line-height: 1.5em;font-weight: bold;margin-top: 24px;margin-bottom: 12px;color: #111111\">What is the recommended boss wall thickness ratio for threaded brass inserts?<\/h3>\n<p style=\"font-size: 18px;line-height: 1.8em;text-align: left;margin-bottom: 24px\">Recommended boss outer diameter (OD) should equal 2.0 to 2.5 times the outer diameter of the metal insert.
