Investment casting wax die lead time is 6\u201310 weeks for a new tool, so the program has to absorb that into the development plan.<\/p>\n<p style=\"margin: 0 0 18px;\">However, once the wax die exists, investment casting cycle time is comparable to sand for many alloys because the shell-dip\/dry\/dewax steps can run in parallel on a multi-day cadence. The bottleneck moves from tooling build to process control (shell thickness, dewax yield, section modulus).<\/p>\n<h2 style=\"font-family: 'Poppins',sans-serif; color: #273171; font-size: 25px; font-weight: 600; line-height: 1.3; margin: 34px 0 14px; padding: 4px 0 4px 30px; background: linear-gradient(to right, #ff512f 0px, #dd2476 5px, transparent 5px);\">Sand Casting vs Investment Casting: Which Should You Choose<\/h2>\n<p style=\"margin: 0 0 18px;\">If you are still unsure after looking at the numbers, this decision tree covers the 80% case:<\/p>\n<ul style=\"margin: 0 0 18px; padding-left: 22px;\">\n<li style=\"margin: 0 0 8px;\"><strong style=\"color: #273171;\">Choose sand casting if:<\/strong> part weight &gt; 5 kg, alloy is iron or carbon steel, volume &gt; 500\/mo, and tolerances \u2264 \u00b10.5 mm are acceptable.<\/li>\n<li style=\"margin: 0 0 8px;\"><strong style=\"color: #273171;\">Choose investment casting if:<\/strong> geometry has undercuts or thin walls, tolerance &lt; \u00b10.2 mm is required, alloy is stainless\/superalloy\/aluminum, and volume is low-to-medium.<\/li>\n<li style=\"margin: 0 0 8px;\"><strong style=\"color: #273171;\">Choose both if:<\/strong> the assembly has a rough body + a tight-tolerance feature.

It is a matching exercise between part geometry, alloy, volume, and tolerance. Most B2B programs that get into trouble picked a process because a brochure said it was &#8220;precision&#8221; or &#8220;economical,&#8221; then hit cost or scrap numbers they did not expect. The right move is to specify your three real constraints (tolerance, weight, volume), get a quote from a foundry that runs both, and let the numbers \u2014 not the marketing \u2014 make the call.<\/p>\n<div class=\"sc-faq\">\n<h3 style=\"font-family: 'Poppins',sans-serif; color: #273171; font-size: 20px; font-weight: 600; line-height: 1.4; margin: 26px 0 12px; text-transform: capitalize;\">Is sand casting always cheaper than investment casting per part?<\/h3>\n<p style=\"margin: 0 0 14px;\">For most alloys above 1 lb (0.5 kg) per piece at volumes above ~300 pc\/mo, yes \u2014 sand casting per-part cost runs roughly 40\u201360% of investment casting on the same alloy. The gap narrows on small stainless parts, where investment casting cluster efficiency offsets pattern cost.<\/p>\n<h3 style=\"font-family: 'Poppins',sans-serif; color: #273171; font-size: 20px; font-weight: 600; line-height: 1.4; margin: 26px 0 12px; text-transform: capitalize;\">Can investment casting replace sand casting 1:1 on the same drawing?<\/h3>\n<p style=\"margin: 0 0 14px;\">Usually yes on geometry and tolerance, but rarely on cost. Investment casting tooling is a step more expensive; if the part does not need the tighter tolerance or surface finish, the extra tooling spend will not pay back. Always re-quote \u2014 never assume 1:1 substitution.<\/p>\n<h3 style=\"font-family: 'Poppins',sans-serif; color: #273171; font-size: 20px; font-weight: 600; line-height: 1.4; margin: 26px 0 12px; text-transform: capitalize;\">How do I verify a foundry actually runs both processes?<\/h3>\n<p style=\"margin: 0 0 14px;\">Ask for a tour and audit their pattern shop (wood\/resin) and their wax room + shell line. A foundry that only runs sand will often try to &#8220;make investment work&#8221; by adding machining; a foundry that only runs investment will downplay volume limitations. A real dual-process shop will tell you where each one falls short.<\/p>\n<h3 style=\"font-family: 'Poppins',sans-serif; color: #273171; font-size: 20px; font-weight: 600; line-height: 1.4; margin: 26px 0 12px; text-transform: capitalize;\">What alloys are off-limits for investment casting?<\/h3>\n<p style=\"margin: 0 0 14px;\">Very high-melting-point alloys (above ~1600 \u00b0C \/ 2900 \u00b0F melt) and very large castings (above ~100 lb \/ 45 kg) become impractical in investment casting because of shell thermal shock and metal inventory per cluster. Sand casting handles both routinely.<\/p>\n<\/div>\n\t\t<div data-elementor-type=\"section\" data-elementor-id=\"3550\" class=\"elementor elementor-3550\" data-elementor-post-type=\"elementor_library\">\n\t\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-19b1acf1 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"19b1acf1\" data-element_type=\"section\" data-e-type=\"section\" data-settings=\"{&quot;background_background&quot;:&quot;classic&quot;,&quot;ekit_has_onepagescroll_dot&quot;:&quot;yes&quot;}\">\n\t\t\t\t\t\t\t<div class=\"elementor-background-overlay\"><\/div>\n\t\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-56e26ed6\" data-id=\"56e26ed6\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-52c3d00c elementor-widget elementor-widget-elementskit-heading\" data-id=\"52c3d00c\" data-element_type=\"widget\" data-e-type=\"widget\" data-settings=\"{&quot;ekit_we_effect_on&quot;:&quot;none&quot;}\" data-widget_type=\"elementskit-heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<div class=\"ekit-wid-con\" ><div class=\"ekit-heading elementskit-section-title-wraper text_left   ekit_heading_tablet-   ekit_heading_mobile-\"><h3 class=\"ekit-heading--title elementskit-section-title\">\uc2e0\ub8b0\ud560 \uc218 \uc788\ub294 \uc911\uad6d \uae08\uc18d \uc8fc\uc870 \uacf5\uc7a5\uc744 \ucc3e\uace0 \uacc4\uc2ed\ub2c8\uae4c?<\/h3><\/div><\/div>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-24c75aa0 elementor-widget elementor-widget-text-editor\" data-id=\"24c75aa0\" data-element_type=\"widget\" data-e-type=\"widget\" data-settings=\"{&quot;ekit_we_effect_on&quot;:&quot;none&quot;}\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<ul><li>\uc6b0\ub9ac\ub294 \uc81c\ud488 \ub514\uc790\uc778\uc744 \ucd5c\uc801\ud654\ud558\uace0 \ube44\uc6a9\uc744 \uc808\uac10\ud558\ub294 \ub370 \ub3c4\uc6c0\uc744 \ub4dc\ub9b4 \uc218 \uc788\uc2b5\ub2c8\ub2e4.<\/li><li>We can help you with high quality high volume cast parts.<\/li><li>\uc6b0\ub9ac\ub294 \uc815\uc2dc \ubc30\uc1a1\uc744 \uc644\ub8cc\ud558\uace0 \ub354 \ub9ce\uc740 \ud310\ub9e4 \uc2dc\uc7a5 \uae30\ud68c\ub97c \ud655\ubcf4\ud560 \uc218 \uc788\uc2b5\ub2c8\ub2e4.<\/li><li>Supro MFG\uc758 \uae08\uc18d \uc8fc\uc870 \uc11c\ube44\uc2a4\ub97c \uc774\uc6a9\ud558\uc2dc\uba74 \ub9ce\uc740 \uc774\uc810\uc744 \ub204\ub9ac\uc2e4 \uc218 \uc788\uc2b5\ub2c8\ub2e4.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-51a20937 elementor-align-left elementor-widget elementor-widget-global elementor-global-1143 elementor-widget-button\" data-id=\"51a20937\" data-element_type=\"widget\" data-e-type=\"widget\" data-settings=\"{&quot;ekit_we_effect_on&quot;:&quot;none&quot;}\" data-widget_type=\"button.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<div class=\"elementor-button-wrapper\">\n\t\t\t\t\t<a class=\"elementor-button elementor-button-link elementor-size-sm elementor-animation-grow\" href=\"https:\/\/chinametalfoundry.com\/ko\/%ec%97%b0%eb%9d%bd%ec%b2%98\/\">\n\t\t\t\t\t\t<span class=\"elementor-button-content-wrapper\">\n\t\t\t\t\t\t\t\t\t<span class=\"elementor-button-text\">\uacf5\uc7a5 \uc9c1\uac70\ub798 \uacac\uc801 \uc694\uccad <\/span>\n\t\t\t\t\t<\/span>\n\t\t\t\t\t<\/a>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t\n<p class=\"sc-note\" style=\"font-size: 13px; color: #7e7e7e; margin-top: 28px; border-top: 1px solid #E5E5E5; padding-top: 12px;\">References: NADCA Product Design Standards for Die Casting (comparable tolerance practice); AFS Foundry Sand Handbook; internal foundry data, last 6 months.
