cyclic shear. Incorporating <strong>mechanical locking features<\/strong> into the rigid plastic substrate provides permanent physical retention that prevents delamination.<\/p>\n<p style=\"font-size: 18px;line-height: 1.8em;text-align: left;margin-bottom: 24px\">Substrates molded from polar engineering plastics like glass-filled <a href=\"https:\/\/www.jcinjectionmolding.com\/ko\/materials\/polyamide-pa-nylon\/\"><strong>PA66<\/strong><\/a> benefit substantially from mechanical locking channels. Designing 90-degree dovetail grooves, undercuts, and through-holes allows molten elastomer to flow through the substrate and rivet on the opposite side.

Meticulous design for manufacturability (DfM) rules eliminate expensive steel modifications and guarantee seamless [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":3208,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-3202","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-blog"],"_links":{"self":[{"href":"https:\/\/www.jcinjectionmolding.com\/ko\/wp-json\/wp\/v2\/posts\/3202","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.jcinjectionmolding.com\/ko\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.jcinjectionmolding.com\/ko\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.jcinjectionmolding.com\/ko\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.jcinjectionmolding.com\/ko\/wp-json\/wp\/v2\/comments?post=3202"}],"version-history":[{"count":0,"href":"https:\/\/www.jcinjectionmolding.com\/ko\/wp-json\/wp\/v2\/posts\/3202\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.jcinjectionmolding.com\/ko\/wp-json\/wp\/v2\/media\/3208"}],"wp:attachment":[{"href":"https:\/\/www.jcinjectionmolding.com\/ko\/wp-json\/wp\/v2\/media?parent=3202"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.jcinjectionmolding.com\/ko\/wp-json\/wp\/v2\/categories?post=3202"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.jcinjectionmolding.com\/ko\/wp-json\/wp\/v2\/tags?post=3202"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
