The part features a wall thickness of only 1.0 mm, with a high-gloss, mark\u2011free exterior surface and localized matte areas requiring a fine texture. During initial mold trials, we encountered significant warpage and visible weld lines on the side walls, which severely impacted cosmetic yield.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"700\" height=\"784\" src=\"https:\/\/rilong-mold.com\/wp-content\/uploads\/2026\/04\/\u5fae\u4fe1\u56fe\u7247_20260427162602_1128_116.jpg\" alt=\"\" class=\"wp-image-7800\" srcset=\"https:\/\/rilong-mold.com\/wp-content\/uploads\/2026\/04\/\u5fae\u4fe1\u56fe\u7247_20260427162602_1128_116.jpg 700w, https:\/\/rilong-mold.com\/wp-content\/uploads\/2026\/04\/\u5fae\u4fe1\u56fe\u7247_20260427162602_1128_116-268x300.jpg 268w, https:\/\/rilong-mold.com\/wp-content\/uploads\/2026\/04\/\u5fae\u4fe1\u56fe\u7247_20260427162602_1128_116-11x12.jpg 11w\" sizes=\"auto, (max-width: 700px) 100vw, 700px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To address these issues, we implemented the following key measures:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Mold Steel &amp; Cooling System Optimization<\/strong><br>Long-life mold steel was adopted, combined with a redesigned conformal cooling layout. This resulted in more uniform core temperature distribution and effectively minimized warpage of the thin\u2011wall part.<\/li>\n\n\n\n<li><strong>Mold Flow Analysis &amp; Gate Location Adjustment<\/strong><br>Multiple gating schemes were evaluated using mold flow analysis. A three\u2011pin sequential valve gate system was ultimately selected, enabling balanced melt front filling. Weld lines were shifted to non\u2011cosmetic areas or completely eliminated.<\/li>\n\n\n\n<li><strong>Fine\u2011Tuning of Process Parameters<\/strong><br>Injection speed, holding pressure, and holding time were segmentally optimized based on mold flow results, resolving surface consistency challenges where high\u2011gloss and matte zones coexist on the same part.<\/li>\n\n\n\n<li><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Project Results<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">After the above optimizations, the TWS earbuds charging case enclosure achieved:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Warpage controlled within \u00b10.05 mm;<\/li>\n\n\n\n<li>High\u2011gloss zones with a mirror\u2011like finish and matte zones with the desired fine texture \u2013 no visible weld lines;<\/li>\n\n\n\n<li>Cycle time reduced from 28 seconds to 21 seconds;<\/li>\n\n\n\n<li>Successful transition to mass production, with mold life reliably exceeding 1 million cycles.<\/li>\n\n\n\n<li><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Design Philosophy<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Having designed dozens of molds for consumer electronics, we have come to realize that good mold design is not about finding the &#8220;most complex solution&#8221; \u2013 it is about striking the best balance between cost, cycle time, and yield for each specific project.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"762\" height=\"652\" src=\"https:\/\/rilong-mold.com\/wp-content\/uploads\/2026\/04\/\u5fae\u4fe1\u56fe\u7247_20260427162600_1126_116.jpg\" alt=\"\" class=\"wp-image-7801\" srcset=\"https:\/\/rilong-mold.com\/wp-content\/uploads\/2026\/04\/\u5fae\u4fe1\u56fe\u7247_20260427162600_1126_116.jpg 762w, https:\/\/rilong-mold.com\/wp-content\/uploads\/2026\/04\/\u5fae\u4fe1\u56fe\u7247_20260427162600_1126_116-300x257.jpg 300w, https:\/\/rilong-mold.com\/wp-content\/uploads\/2026\/04\/\u5fae\u4fe1\u56fe\u7247_20260427162600_1126_116-14x12.jpg 14w\" sizes=\"auto, (max-width: 762px) 100vw, 762px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">We welcome discussions with anyone interested in precision injection molding and mold structure optimization.<\/p>\n\n\n\n<p class=\"rilong-related-capability wp-block-paragraph\"><strong>Related capability:<\/strong> Explore Rilong\u2019s <a href=\"\/es\/mold-designing-tooling\/\">mold design and tooling capabilities<\/a>, or send your drawing and production requirements for a technical review.<\/p>","protected":false},"excerpt":{"rendered":"<p>Electronics enclosure mold design: This article explains the key design, material, process, quality, and production considerations that engineers and sourcing teams should evaluate.
