    It can reduce cold-runner waste and change the vestige, but the melt still enters through a gate and can create local shear, heat and stress. Tip condition and temperature balance become additional controls.<\/p>\n

    Is the gate always placed in the thickest section?<\/h3>\n

    That is a useful packing principle, not an absolute rule. Optical surfaces, weld lines, trimming and flow orientation may justify another location.<\/p>\n

    What should be reviewed before steel?<\/h3>\n

    The optical-zone map, gate alternatives, fill and pack behavior, vent locations, trimming access, ejection, inspection method and acceptable process window.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"

    One gate can distort an entire optical path without leaving an obvious surface defect. Gate design for optical injection molding controls how the cavity fills, where orientation develops, how long packing pressure reaches the part, and where the gate vestige remains. A gate that produces a complete, glossy part can still create birefringence, focal shift […]<\/p>\n","protected":false},"author":1,"featured_media":3779,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-3727","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-blog"],"_links":{"self":[{"href":"https:\/\/www.jcinjectionmolding.com\/vi\/wp-json\/wp\/v2\/posts\/3727","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.jcinjectionmolding.com\/vi\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.jcinjectionmolding.com\/vi\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.jcinjectionmolding.com\/vi\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.jcinjectionmolding.com\/vi\/wp-json\/wp\/v2\/comments?post=3727"}],"version-history":[{"count":0,"href":"https:\/\/www.jcinjectionmolding.com\/vi\/wp-json\/wp\/v2\/posts\/3727\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.jcinjectionmolding.com\/vi\/wp-json\/wp\/v2\/media\/3779"}],"wp:attachment":[{"href":"https:\/\/www.jcinjectionmolding.com\/vi\/wp-json\/wp\/v2\/media?parent=3727"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.jcinjectionmolding.com\/vi\/wp-json\/wp\/v2\/categories?post=3727"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.jcinjectionmolding.com\/vi\/wp-json\/wp\/v2\/tags?post=3727"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
