In the centre lies the cavity (negative of the external shape) and core (creating internal features). Liquid plastic is injected through a system of injection, cooling, solidification, and ejection consistently, which is a full injection molding cycle. Standard steels are P20, H13, and S136 stainless, and prototypes are made of CNC machining,3d printing, and vacuum casting.<br><\/p><div class=\"mold-diagram-wrapper\" id=\"moldApp\"><div class=\"mold-header\"><h2>Injection Mold Structure<\/h2><p class=\"subtitle\">Interactive Engineering Guide \u2014 Click markers to explore components<\/p><\/div><div class=\"mold-layout\"><div class=\"mold-img-container\" id=\"moldImgContainer\"><img decoding=\"async\" src=\"https:\/\/www.plasticmoulds.net\/wp-content\/uploads\/2025\/08\/injection-mold-structurer.webp\" alt=\"Injection Mold Structure\" id=\"moldImg\" class=\"skip-lazy\" style=\"min-height: 300px; background: #f0f0f0;\" \/><\/div><div class=\"mold-info-panel\"><div id=\"moldInfoContent\"><div class=\"mold-placeholder\"><div class=\"icon\"><svg viewBox=\"0 0 24 24\" width=\"30\" fill=\"#e8b84b\"><path d=\"M12 2a10 10 0 1 0 10 10A10 10 0 0 0 12 2zm1 15h-2v-2h2zm0-4h-2V7h2z\"\/><\/svg><\/div><p>Select a component from the diagram or list to view technical details.<\/p><\/div><\/div><div class=\"mold-parts-list\" id=\"moldPartsList\"><\/div><div class=\"mold-cta\"><a href=\"\/contact-us\/\" class=\"cta-button\">Get a Fast Quote<\/a><\/div><\/div><\/div><\/div><style> .mold-diagram-wrapper{max-width:1200px;margin:30px auto;font-family:var(--theme-font-family, sans-serif);} .mold-header h2{font-weight:800;margin-bottom:5px;color:#1a1a2e;} .mold-header .subtitle{font-size:0.85rem;color:#888;text-transform:uppercase;margin-bottom:25px;} .mold-layout{display:grid;grid-template-columns:1fr 340px;gap:25px;align-items:start;} .mold-img-container{position:relative;border-radius:12px;box-shadow:0 5px 25px rgba(0,0,0,0.1);overflow:hidden;} .mold-img-container img{width:100%;display:block;height:auto;} .mold-hotspot{position:absolute;width:20px;height:20px;background:#e8b84b;border:2px solid #fff;border-radius:50%;cursor:pointer;z-index:100;transform:translate(-50%, -50%);box-shadow:0 0 10px rgba(0,0,0,0.3);transition:all 0.2s ease;} .mold-hotspot.active{background:#ef4444;transform:translate(-50%, -50%) scale(1.3);} .mold-info-panel{background:#fff;border:1px solid #eee;border-radius:12px;position:sticky;top:90px;} .mold-info-header{background:#1a1a2e;color:#fff;padding:20px;border-radius:12px 12px 0 0;} .mold-info-header .part-name{font-size:1.25rem;font-weight:700;display:block;} .mold-info-body{padding:20px;min-height:120px;} .mold-parts-list{border-top:1px solid #f0f0f0;max-height:250px;overflow-y:auto;} .mold-part-btn{width:100%;padding:10px 20px;border:none;border-bottom:1px solid #f9f9f9;text-align:left;background:none;cursor:pointer;font-size:0.85rem;} .mold-part-btn:hover{background:#fffbeb;} .mold-part-btn.active{background:#1a1a2e;color:#e8b84b;} .mold-cta{padding:15px;} .cta-button{display:block;background:#e8b84b;color:#fff;text-align:center;padding:10px;border-radius:6px;text-decoration:none;font-weight:700;} @media (max-width:850px){.mold-layout{grid-template-columns:1fr;} .mold-info-panel{position:static;} } <\/style><script> (function() { const parts = [ { id: \"mould_housing\", en: \"Mould Housing\", x: 42, y: 8, desc: \"The outer structural shell encasing all internal mold components.\" }, { id: \"bottom_clamping\", en: \"Bottom Clamping Platen\", x: 14, y: 15, desc: \"Bolted to the machine's fixed platen to distribute clamping force.\" }, { id: \"support_plate\", en: \"Support Plate\", x: 50, y: 12, desc: \"Rigid plate preventing deflection under high injection pressure.\" }, { id: \"core_plate\", en: \"Core Plate\", x: 62, y: 12, desc: \"Houses the core insert; forms the moving half of the parting surface.\" }, { id: \"core_insert\", en: \"Core Insert\", x: 78, y: 12, desc: \"Hardened steel forming the male geometry.

The mechanism and major components of the mold have been briefly summarized below.<\/p><h3 class=\"wp-block-heading\" id=\"definition-and-major-components\">Definition and Major Components<\/h3><p>A plastic mold is built around two main forming sections: the cavity side, which shapes the outer surface of the part, and the core side, which forms internal features such as ribs, bosses, holes, and undercuts. Around these forming areas, the mold also includes the runner and gate system, cooling channels, ejector system, guide components, and support plates. Together, these components control how the molten plastic flows, cools, shrinks, and is finally released from the mold.<\/p><p>Injection molding process: plastic is melted and injected or pressed into the mold cavity under constant pressure from the press, and hardens during cooling. The part is ejected after the mold opens, and the cycle is repeated. The quality of parts is based on plastic material, steel, geometry, gating, cooling layout, and ejection way.<\/p><p>Related reading:&nbsp;<a href=\"https:\/\/www.plasticmoulds.net\/plastic-mold-offer-from-china\" target=\"_blank\" rel=\"noreferrer noopener\">Our Mold Manufacturing Services<\/a>&nbsp;<\/p><h2 class=\"wp-block-heading\" id=\"6-types-of-plastic-molding\">What Are main Types of Plastic Mold?<\/h2><p>There are six main plastic mold. Each suits different part shapes, volumes, and budgets. Injection molding is the most versatile for complex, high-volume parts. Blow molding creates hollow containers. Compression molding works best for large flat thermoset parts. Extrusion produces continuous profiles like pipes. Rotational molding makes large hollow items.
