A straight side core is often more direct when the feature needs dedicated lateral withdrawal. Geometry, travel, and mold layout decide; neither mechanism is a universal default.<\/p>\n<p>Undercut depth, draft, wall thickness, ejection direction, and nearby ribs determine whether the lifter can clear without dragging. Deep features may require excessive travel or leave the lifter too slender to remain rigid. Review the part in section as well as in the full mold assembly.<\/p>\n<h2 id=\"motion\">How should lifter movement be coordinated?<\/h2>\n<p>The ejector plate drives the lifter forward while its guide path creates lateral displacement. The part must stay supported as the undercut clears. Otherwise, the feature can flex, whiten, crack, or remain caught. Show the full motion and confirm that the lifter clears before handling or robot takeout.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-large\" src=\"https:\/\/www.jcinjectionmolding.com\/wp-content\/uploads\/2026\/11\/angled-lifter-ejection-motion.webp\" alt=\"Angled lifter clears internal undercut\" \/><\/p>\n<p>Check head contact area, guide length, support at full extension, and clearance to adjacent ejectors. Shrinkage can tighten the part around the steel; texture can also change release. A CAD animation helps expose collisions but does not prove that the molded part will eject without damage.<\/p>\n<h2 id=\"risks\">\uc5b4\ub5a4 \uc2e4\ud328\uac00 \ub9ac\ud504\ud130 \uc124\uacc4
