Customers come to us when they need parts that combine rubber-like flexibility with thermoplastic recyclability \u2014 think cable overmolds, wearable device skins, and industrial seals. The chemistry behind TPU consists of alternating hard segments (from diisocyanate and chain extender) and soft segments (from polyol), which create its signature combination of strength and elasticity at the molecular level.<\/p>\n<figure style=\"text-align:center;margin:2em 0;\">\n<img fetchpriority=\"high\" decoding=\"async\" width=\"800\" height=\"457\" src=\"https:\/\/zetarmold.com\/wp-content\/uploads\/2026\/04\/injection-molding-process-flow-800x457-1.jpg\" alt=\"Injection Molding Process Flowchart\" class=\"wp-image-53261 size-full\" style=\"max-width:100%;height:auto;\" srcset=\"https:\/\/zetarmold.com\/wp-content\/uploads\/2026\/04\/injection-molding-process-flow-800x457-1.jpg 800w, https:\/\/zetarmold.com\/wp-content\/uploads\/2026\/04\/injection-molding-process-flow-800x457-1-300x171.jpg 300w, https:\/\/zetarmold.com\/wp-content\/uploads\/2026\/04\/injection-molding-process-flow-800x457-1-768x439.jpg 768w, https:\/\/zetarmold.com\/wp-content\/uploads\/2026\/04\/injection-molding-process-flow-800x457-1-18x10.jpg 18w, https:\/\/zetarmold.com\/wp-content\/uploads\/2026\/04\/injection-molding-process-flow-800x457-1-600x343.jpg 600w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><figcaption style=\"font-size:0.78em; color:#888; font-style:italic; margin-top:4px; text-align:center;\">TPU injection molding process flow<\/figcaption><\/figure>\n<p>TPU injection molding follows the same fundamental cycle as any thermoplastic: plasticizing, injection, packing, cooling, and ejection.

TPE (SEBS-based) costs 20\u201330% less per kilogram and processes more easily, but drop test results were consistently 15\u201325% worse with TPE versus a comparable Shore 85A TPU grade. When mechanical performance under repeated impact is critical, TPU wins.<\/p>\n<h2>What Design Guidelines Should You Follow for TPU Parts?<\/h2>\n<p>TPU parts are best designed with 1.5\u20134.0 mm walls, 2\u20133\u00b0 draft for soft grades, gate diameter \u22651.5 mm, and gradual transitions. TPU flexes enough to demold 3\u20135% undercuts without sliders.<\/p>\n<p><strong>Duvar Kal\u0131nl\u0131\u011f\u0131:<\/strong> Very thin walls (6 mm) produce long cooling times and potential voids. Uniform wall thickness is especially important with TPU \u2014 sudden changes cause differential shrinkage that creates warpage.<\/p>\n<p><strong>Taslak A\u00e7\u0131lar\u0131:<\/strong> This is where we see the most design revisions. Shore 60A\u201375A grades need 2\u20133\u00b0 minimum, and 3\u20135\u00b0 for textured surfaces. TPU grips the mold core during cooling, so generous draft is essential for reliable ejection.<\/p>\n<p><strong>Alttan kes:<\/strong> Unlike rigid plastics, TPU can accommodate minor undercuts (3\u20135% of part diameter) by flexing during demolding. This reduces tooling complexity \u2014 many features that would require sliders in ABS can be directly demolded with TPU.<\/p>\n<p><strong>Kap\u0131 Tasar\u0131m\u0131:<\/strong> Submarine gates are popular for TPU because they self-degate. Gate diameter must be 1.5\u20132.5 mm minimum \u2014 undersized gates cause excessive shear. Avoid pin gates smaller than 1.0 mm with soft grades.<\/p>\n<table style=\"width:100%;border-collapse:collapse;margin:1.5em 0;\">\n<caption style=\"font-weight:bold;margin-bottom:0.5em;\">Authority checkpoint 1<\/caption>\n<thead>\n<tr>\n<th style=\"border:1px solid #ddd;padding:8px;background:#f5f5f5;\">Kontrol noktas\u0131 1 alan\u0131<\/th>\n<th style=\"border:1px solid #ddd;padding:8px;background:#f5f5f5;\">Kontrol noktas\u0131 1 do\u011frulamas\u0131<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"border:1px solid #ddd;padding:8px;\">re\u00e7ine \u00f6zellikleri<\/td>\n<td style=\"border:1px solid #ddd;padding:8px;\">Kal\u0131p tasar\u0131m\u0131n\u0131n TPU Enjeksiyon Kal\u0131plamay\u0131 nas\u0131l etkiledi\u011fini onaylay\u0131n: M\u00fchendisler i\u00e7in Tam \u0130\u015fleme K\u0131lavuzu.<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #ddd;padding:8px;\">Malzeme<\/td>\n<td style=\"border:1px solid #ddd;padding:8px;\">Check resin behavior, shrinkage, heat, and cosmetic risks.<\/td>\n<\/tr>\n<tr>\n<td style=\"border:1px solid #ddd;padding:8px;\">Kalite<\/td>\n<td style=\"border:1px solid #ddd;padding:8px;\">Ask for inspection evidence before production approval.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<figure style=\"text-align:center;margin:2em 0;\">\n<img decoding=\"async\" width=\"800\" height=\"457\" src=\"https:\/\/zetarmold.com\/wp-content\/uploads\/2026\/04\/injection-molding-draft-angle-diagram-800x457-1.jpg\" alt=\"TPU par\u00e7alar i\u00e7in enjeksiyon kal\u0131plama pah a\u00e7\u0131s\u0131 tasar\u0131m \u015femas\u0131\" class=\"wp-image-53346 size-full\" style=\"max-width:100%;height:auto;\" srcset=\"https:\/\/zetarmold.com\/wp-content\/uploads\/2026\/04\/injection-molding-draft-angle-diagram-800x457-1.jpg 800w, https:\/\/zetarmold.com\/wp-content\/uploads\/2026\/04\/injection-molding-draft-angle-diagram-800x457-1-300x171.jpg 300w, https:\/\/zetarmold.com\/wp-content\/uploads\/2026\/04\/injection-molding-draft-angle-diagram-800x457-1-768x439.jpg 768w, https:\/\/zetarmold.com\/wp-content\/uploads\/2026\/04\/injection-molding-draft-angle-diagram-800x457-1-18x10.jpg 18w, https:\/\/zetarmold.com\/wp-content\/uploads\/2026\/04\/injection-molding-draft-angle-diagram-800x457-1-600x343.jpg 600w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><figcaption style=\"font-size:0.78em; color:#888; font-style:italic; margin-top:4px; text-align:center;\">TPU par\u00e7a pah a\u00e7\u0131s\u0131 tasar\u0131m\u0131<\/figcaption><\/figure>\n<p><strong>\u00dcst kal\u0131plama:<\/strong> TPU, rijit alt tabakalar (ABS, PC, PC\/ABS, naylon) \u00fczerine a\u015f\u0131r\u0131 kal\u0131plama i\u00e7in en \u00e7ok y\u00f6nl\u00fc malzemelerden biridir.
