Generally, anything that a bearing or seal rides on requires \u00b10.02 to \u00b10.05 mm. A tolerance of 0.3 to 0.8 mm of stock should be planned for machining.<\/li>\n\n\n\n<li>Flat sealing faces. A facing pass is almost always applied to gasket and O-ring surfaces.<\/li>\n\n\n\n<li>The following M6 threads are tapped. Small threads can be cut or formed after being cast; larger cast-in threads are possible.<\/li>\n\n\n\n<li>Concentricity (or true-position relationships) smaller than about \u00b1 0.03 mm. These features should be machined in a single set up from the same datum.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">To allow intentional machining stock in just those faces to allow the finishing operation to remove clean metal and not engage residual warp or shrinkage variation in the mold.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Tolerances on a Casting Drawing<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">There are four practical rules to be followed in making drawings:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Tightly mark the functional faces. Precision or individual tolerances are applied to bearing seats, sealing faces, mating threads, and alignment features.<\/li>\n\n\n\n<li>Allow surfaces that don&#8217;t perform a function to breathe. As cast tolerances on non-critical dimensions are standard, they also come without additional cost and do not restrict the process.<\/li>\n\n\n\n<li>Prefer GD&amp;T for positional relationships. It is a straightforward callout and much easier for a supplier to quote and check than a pile of bilateral linear tolerances.<\/li>\n\n\n\n<li>Explicitly identify which faces will be machined. The caster can then form the proper stock allowance during the forming process.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">A general tolerance note in or adjacent to the title block should refer to either NADCA Section 4A (Standard or Precision) or ISO 8062-3 and the relevant DCTG grade. Individual tighter tolerances are specified only where needed to override the general note.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/www.diecastingschina.com\/wp-content\/uploads\/2026\/10\/2-1-1024x576.jpg\" alt=\"\" class=\"wp-image-2604\" srcset=\"https:\/\/www.diecastingschina.com\/wp-content\/uploads\/2026\/10\/2-1-1024x576.jpg 1024w, https:\/\/www.diecastingschina.com\/wp-content\/uploads\/2026\/10\/2-1-300x169.jpg 300w, https:\/\/www.diecastingschina.com\/wp-content\/uploads\/2026\/10\/2-1-768x432.jpg 768w, https:\/\/www.diecastingschina.com\/wp-content\/uploads\/2026\/10\/2-1-18x10.jpg 18w, https:\/\/www.diecastingschina.com\/wp-content\/uploads\/2026\/10\/2-1-1536x864.jpg 1536w, https:\/\/www.diecastingschina.com\/wp-content\/uploads\/2026\/10\/2-1.jpg 1920w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Factors That Limit Achievable Tolerance<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">However, many physical and process factors limit the amount that can be stored even in the published tables:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Part size and shape<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">These are the most challenging and are usually large, thin-walled, or abrupt changes in wall thickness.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Wear and alignment of the dies<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A gradual increase in the amount of shifting occurs between the two halves over the life of the tool.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Clamping force<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">When the machine size is not adequate for the area to be produced, the die will open up a little bit under the injection pressure, creating some variation in each of the dimensions that cross the parting line.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Shrinkage properties and solidification of alloys<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Final dimensions are affected by process parameters such as metal temperature, velocity profile, die temperature, and cycle timing.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If a tolerance is required that is more precise than the NADCA precision for the feature length or the corresponding ISO for the feature length, the economical answer is nearly always to cast with stock and machine the feature.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Methods of Quality Control for ensuring Tolerance Capability<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Today&#8217;s modern <a href=\"https:\/\/aludiecasting.com\/aluminum-die-casting\/\" target=\"_blank\" rel=\"noopener\">\uc54c\ub8e8\ubbf8\ub284 \ub2e4\uc774\uce90\uc2a4\ud305<\/a> facilities incorporate conventional gauging with modern non-destructive techniques and statistical process control. Coordinate measuring machines are used to check first articles and, on a sample basis, critical dimensions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, if internal porosity or cold shut is found during real-time X-ray or, if warranted by the situation, during on-line CT, it can be a sign of an integrity issue even if the external dimensional tolerances are met. Key process variables and capability keys are tracked using statistical process control to ensure that the process is corrected before parts are out of specification.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Ppk is sometimes needed to be greater than 1.67 at PPAP for critical characteristics. Since new dies are designed with intentional tolerances for wear, so that the dimensions are closer to the nominal, NAO (as-cast) is more applicable to assess the feature using Cp rather than Cpk.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Practical Guidelines for Designers and Procurement Teams<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Whenever possible, keep all main datums in one die half and off slides. Dimensions measured from a datum in the opposite half automatically pick up parting-line and shift adders.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Use a draft early (usually of 1-3\u00b0 depending on draft depth) to prevent distortion of the part by the ejection force.<\/li>\n\n\n\n<li>Select alloys that have a known shrinkage, if close as-cast tolerances are needed.<\/li>\n\n\n\n<li>Communicate with the caster at the design phase about parting line, draft, datum scheme, and the features that will be machined.<\/li>\n\n\n\n<li><strong>Machining stock<\/strong>: 0.3 to 0.8 mm is left for most aluminum components 100 \u2013 300 mm in size. The volume of stock should not be too high, or it wastes material and cycle time, nor too low, or the cleanup will not be complete.<\/li>\n<\/ul>\n\n\n\n<ol class=\"wp-block-list\">\n<li>The functional requirements and cost, all considered, can be met with aluminum die castings, routinely, using these practices.<\/li>\n<\/ol>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/www.diecastingschina.com\/wp-content\/uploads\/2026\/10\/4-3-1024x576.jpg\" alt=\"\" class=\"wp-image-2605\" srcset=\"https:\/\/www.diecastingschina.com\/wp-content\/uploads\/2026\/10\/4-3-1024x576.jpg 1024w, https:\/\/www.diecastingschina.com\/wp-content\/uploads\/2026\/10\/4-3-300x169.jpg 300w, https:\/\/www.diecastingschina.com\/wp-content\/uploads\/2026\/10\/4-3-768x432.jpg 768w, https:\/\/www.diecastingschina.com\/wp-content\/uploads\/2026\/10\/4-3-1536x864.jpg 1536w, https:\/\/www.diecastingschina.com\/wp-content\/uploads\/2026\/10\/4-3-18x10.jpg 18w, https:\/\/www.diecastingschina.com\/wp-content\/uploads\/2026\/10\/4-3.jpg 1920w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">\uc790\uc8fc \ubb3b\ub294 \uc9c8\ubb38<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">What are the common tolerances for the aluminum die casting?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Under normal production conditions, the as-cast linear tolerances of aluminum are normally \u00b10.10 mm for a value below 25 mm, and \u00b10.25\u20130.35 mm for a value larger than 25 mm. The formal reference is provided by NADCA Standard or Precision tables or ISO 8062-3 tables (DCTG 6\u20139 if overall part size).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Is it possible to die cast aluminum?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes. Aluminum is one of the most commonly die-cast metals in the world. A380, ADC12, and A356 are among the many alloys commonly used on both hot-chamber (less common for aluminum) and cold-chamber high-pressure die casting machines. They create complex geometries, thin walls, excellent surface finish, and high production rates for automotive, electronics, industrial, and consumer applications.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Can 6061 aluminum be used for casting?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">6061 is a very good wrought alloy, and not a desirable alloy for die casting. It is not as well suited for high-pressure die casting as the dedicated casting alloys, A380 or ADC12, because of its solidification properties, fluidity, and shrinkage. The mechanical property specifications for the material of the original design are nearly always different when the design is transferred to die casting, and it is also frequently necessary to change the tolerances on the material.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What are the normal tolerances of aluminum?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In regard to die casting, but outside of the specific process, the term \u201cstandard tolerances for aluminum\u201d can apply to a number of processes (extrusion, machining, sheet metal, etc.). In high-pressure die casting, the relevant standards are the NADCA Product Specification Standards (Section 4A) and ISO 8062-3. The typical as-cast tolerance is about \u00b10.10 mm, which increases with feature size, and precision grades have slightly smaller bands on some dimensions.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">\uacb0\ub860<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/aludiecasting.com\/aluminum-die-casting\/\" target=\"_blank\" rel=\"noopener\">\uc54c\ub8e8\ubbf8\ub284 \ub2e4\uc774\uce90\uc2a4\ud305<\/a> offers excellent productivity and complexity, but its dimensional ability is ultimately limited by solidification physics, die design, and process control. The practical cast tolerances of \u00b10.10 mm for small features and \u00b10.25-0.35 mm for larger features are realistic and economical based on the standard or ISO 8062-3 guidelines of NADCA.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Selected dimensions can be further tightened with precision grades and controlled processes, but it is almost always necessary to intentionally machine stock and perform secondary operations to ensure critical bores, sealing faces, and close positional relationships.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Have experienced die casters involved at the early stage, define the tolerances that count, and aluminum die casting is an extremely effective way to get precision parts that assemble easily and reliably in production.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>","protected":false},"excerpt":{"rendered":"<p>Introduction Talking about aluminum die-casting tolerances is probably the most productive conversation you can have in the precision manufacturing world.
