If your single-cavity mold runs a 20-second cycle, switching to an 8-cavity tool gives you 8\u00d7 the parts in the same 20 seconds (cycle time may increase slightly\u2014typically 5\u201315%\u2014due to larger shot size and cooling demands, but the net throughput gain is enormous).<\/p>\n<p>In our experience at ZetarMold, the advantages break down like this:<\/p>\n<p><b>Lower per-part cost<\/b> \u2013 Machine hourly rate is divided across more parts. A 16-cavity mold can cut piece price by 60\u201380% versus a single-cavity tool.<\/p>\n<p><b>Reduced labor per part<\/b> \u2013 One operator runs one press regardless of cavity count.<\/p>\n<p><b>Faster time to volume<\/b> \u2013 High-volume launches meet demand sooner without needing multiple molds or presses.<\/p>\n<p><b>Consistent quality<\/b> \u2013 All parts come from the same process conditions in the same shot, reducing lot-to-lot variation.<\/p>\n<p>We\u2019ve seen customers cut their total program cost by 40% simply by moving from a 4-cavity to a 16-cavity mold on a bottle cap project producing 50 million units per year.<\/p>\n<h2>What Are the Common Challenges and How Do You Solve Them?<\/h2>\n<p>The most common challenges are fill imbalance, uneven cooling, higher upfront tooling cost, and more complex maintenance.

By producing multiple identical parts per cycle, it slashes per-unit cost, maximizes press utilization, and delivers consistent quality across every cavity. The trade-off is higher upfront tooling investment and greater engineering complexity\u2014but for programs above 100,000 parts per year, the economics almost always favor multi-cavity tooling.<\/p>\n<p>ZetarMold\uc5d0\uc11c\ub294 \ud328\ud0a4\uc9d5, \uc758\ub8cc, \uc790\ub3d9\ucc28 \ubc0f \uc18c\ube44\uc790 \uc804\uc790\uc81c\ud488 \ubd84\uc57c\uc5d0 \uac78\uccd0 2\uac1c\uc5d0\uc11c 128\uac1c \uce90\ube44\ud2f0\uc5d0 \uc774\ub974\ub294 \uc218\ubc31 \uac1c\uc758 \ub2e4\uc911 \uce90\ube44\ud2f0 \uae08\ud615\uc744 \uc81c\uc791\ud588\uc2b5\ub2c8\ub2e4. \uc6b0\ub9ac\uc758 \uc811\uadfc \ubc29\uc2dd\uc740 \uae08\ud615 \ud750\ub984 \uc2dc\ubbac\ub808\uc774\uc158, \u00b10.005 mm \uc815\ubc00\ub3c4\uc758 CNC \uac00\uacf5 \ubc0f \uc5c4\uaca9\ud55c \uc2dc\ud5d8 \ud504\ub85c\ud1a0\ucf5c\uc744 \uacb0\ud569\ud558\uc5ec \ubaa8\ub4e0 \uce90\ube44\ud2f0\uac00 \ub3d9\uc77c\ud558\uac8c \uc791\ub3d9\ud558\ub3c4\ub85d \ubcf4\uc7a5\ud569\ub2c8\ub2e4. \ub300\ub7c9 \uc0dd\uc0b0 \ud504\ub85c\uadf8\ub7a8\uc744 \uacc4\ud68d \uc911\uc774\uace0 \ub2e4\uc911 \uce90\ube44\ud2f0 \uae08\ud615\uc744 \ud0d0\uc0c9\ud558\uace0 \uc2f6\ub2e4\uba74, \ubb34\ub8cc DFM \uac80\ud1a0 \ubc0f \uce90\ube44\ud2f0 \uc218 \ucd94\ucc9c\uc744 \uc704\ud574 \ub2f9\uc0ac\uc758 \uc5d4\uc9c0\ub2c8\uc5b4\ub9c1 \ud300\uc5d0 \ubb38\uc758\ud558\uc2ed\uc2dc\uc624.<\/p>\n<p>Need a Quote for Your Injection Molding Project?<\/p>\n<p>Get competitive pricing, DFM feedback, and production timeline from ZetarMold\u2019s engineering team.<\/p>\n<p>Request a Free Quote \u2192<\/p>\n<hr style=\"margin:2em 0;border:none;border-top:1px solid #e0e0e0;\" \/>\n<ol class=\"footnotes\">\n<li id=\"fn:2\">\n<p><strong>injection mold:<\/strong> injection mold refers to an injection mold is the precision tool that defines part geometry, cooling behavior, ejection, gating, surface finish, and repeatability. <a href=\"#fnref1:1\" class=\"footnote-backref\">\u21a9<\/a><\/p>\n<\/li>\n<li id=\"fn:2\">\n<p><strong>injection molding:<\/strong> injection molding refers to is the production process that melts plastic, injects it into a mold cavity, cools the part, and repeats the cycle for stable volume manufacturing. <a href=\"#fnref1:2\" class=\"footnote-backref\">\u21a9<\/a><\/p>\n<\/li>\n<li id=\"fn:3\">\n<p><strong>plastic:<\/strong> Plastic is a material family whose flow, shrinkage, strength, heat resistance, cosmetic quality, cycle time, and long-term performance shape molding decisions. <a href=\"#fnref1:3\" class=\"footnote-backref\">\u21a9<\/a><\/p>\n<\/li>\n<\/ol>","protected":false},"excerpt":{"rendered":"<p>\ub2e4\uc911 \uce90\ube44\ud2f0 \uc0ac\ucd9c \uae08\ud615\uc774\ub780 \uc815\ud655\ud788 \ubb34\uc5c7\uc778\uac00? \ud575\uc2ec \uc694\uc57d \ub2e4\uc911 \uce90\ube44\ud2f0 \uc0ac\ucd9c \uae08\ud615\uc740 \ud55c \ubc88\uc758 \uc0ac\ucd9c\ub85c \uc5ec\ub7ec \ub3d9\uc77c\ud55c \ubd80\ud488\uc744 \uc0dd\uc0b0\ud558\uc5ec \ub2e8\uc704\ub2f9 \ube44\uc6a9\uacfc \uc0ac\uc774\ud074 \uc2dc\uac04\uc744 \ud68d\uae30\uc801\uc73c\ub85c \uc808\uac10\ud569\ub2c8\ub2e4 \uce90\ube44\ud2f0 \uc218\ub294 \uc5f0\uac04 \uc0dd\uc0b0\ub7c9, \ubd80\ud488 \ud06c\uae30, \ud504\ub808\uc2a4 \ud1a0\ub108\uc9c0\uc5d0 \ub530\ub77c 2\uac1c\uc5d0\uc11c 128\uac1c \uc774\uc0c1\uae4c\uc9c0 \uc120\ud0dd\ub429\ub2c8\ub2e4 \uade0\ud615 \uc7a1\ud78c \ub7ec\ub108 \uc124\uacc4\uc640 \uade0\uc77c\ud55c \ub0c9\uac01\uc740 [\u2026]<\/p>","protected":false},"author":1,"featured_media":38013,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_seopress_robots_primary_cat":"none","_seopress_titles_title":"What Is a Multiple Cavity Injection Mold? | ZetarMold","_seopress_titles_desc":"Learn how multiple cavity injection molds boost production by 8-16x while cutting per-part costs up to 80%.
