Thick solid walls cool slowly and contract unevenly, causing deep sink shadows on appearance surfaces. Designing structural reinforcing ribs with a base thickness of 50% to 60% of the nominal wall increases bending stiffness without adding mass. Configuring balanced cooling water networks close to core and cavity surfaces extracts heat evenly across large surface areas. Gas-assisted molding technology can also be integrated to inject nitrogen gas into thick rib sections, creating hollow cores that eliminate sink marks.<\/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\">H\u00e4ufig gestellte Fragen (FAQs)<\/h2>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-2836\" src=\"https:\/\/www.jcinjectionmolding.com\/wp-content\/uploads\/2026\/08\/optical-scanning-large-plastic-part.webp\" alt=\"optical-scanning-large-plastic-part\" width=\"1376\" height=\"768\" srcset=\"https:\/\/www.jcinjectionmolding.com\/wp-content\/uploads\/2026\/08\/optical-scanning-large-plastic-part.webp 1376w, https:\/\/www.jcinjectionmolding.com\/wp-content\/uploads\/2026\/08\/optical-scanning-large-plastic-part-300x167.webp 300w, https:\/\/www.jcinjectionmolding.com\/wp-content\/uploads\/2026\/08\/optical-scanning-large-plastic-part-1024x572.webp 1024w, https:\/\/www.jcinjectionmolding.com\/wp-content\/uploads\/2026\/08\/optical-scanning-large-plastic-part-768x429.webp 768w\" 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 Sequential Valve Gating (SVG) and why is it used for large parts?<\/h3>\n<p style=\"font-size: 18px;line-height: 1.8em;text-align: left;margin-bottom: 24px\">Sequential Valve Gating uses electronically controlled needle valves inside hot runner nozzles to open and close gate ports in a specific sequence.
