class=\"ez-toc-section-end\"><\/span><\/h1>\n<p>Choosing between gravity die casting (GDC) and high pressure die casting (HPDC) is one of the most important decisions you will make when sourcing aluminium castings. Both processes use permanent metal dies, but they fill those dies in fundamentally different ways \u2014 one by gravity, the other under very high injection pressure. That single difference drives almost everything that follows: achievable tolerances, minimum wall thickness, mechanical properties, whether the part can be heat treated, tooling cost, and the production volume at which each process becomes economical. This guide compares the two processes head-to-head and gives you a practical framework for choosing the right one.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Gravity_Die_Casting_GDC_%E2%80%94_Permanent-Mold_Casting\"><\/span>Gravity Die Casting (GDC) \u2014 Permanent-Mold Casting<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>In gravity die casting, molten metal is poured into a metal die and fills the cavity purely under gravity \u2014 no external pressure is applied. It is the simplest of the die-casting processes and needs only a modest capital investment. <a href=\"https:\/\/aludiecasting.com\/pt\/gravity-die-casting-mold-process-and-post-machining\/\">Gravity die casting molds<\/a> are made of fine-grained pearlitic cast iron or low-alloy steel and are coated with a refractory dressing that controls how quickly heat is drawn from the solidifying casting. Because cooling is faster than in sand casting but gentler than in HPDC, gravity castings develop a finer grain and roughly 20% higher mechanical properties than sand castings, while remaining dense and leak-tight. Gravity casting can also use resin-bonded sand cores to form complex internal passages that a high-pressure process cannot achieve. Typical output ranges from about 1,000 to more than 100,000 castings per year per die, and parts can weigh from under 1 kg up to around 300 kg.<\/p>\n<p><a href=\"https:\/\/aludiecasting.com\/wp-content\/uploads\/2026\/11\/Gravity-die-casting-mold-1.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-21114\" src=\"https:\/\/aludiecasting.com\/wp-content\/uploads\/2026\/11\/Gravity-die-casting-mold-1.jpg\" alt=\"Gravity die casting mold\" width=\"948\" height=\"740\" srcset=\"https:\/\/aludiecasting.com\/wp-content\/uploads\/2026\/11\/Gravity-die-casting-mold-1.jpg 948w, https:\/\/aludiecasting.com\/wp-content\/uploads\/2026\/11\/Gravity-die-casting-mold-1-480x375.jpg 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) 948px, 100vw\" \/><\/a><\/p>\n<h2><span class=\"ez-toc-section\" id=\"High_Pressure_Die_Casting_HPDC\"><\/span>Fundi\u00e7\u00e3o sob press\u00e3o de alta press\u00e3o (HPDC)<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>In high pressure die casting, molten alloy is injected into a split steel die at high speed and high pressure \u2014 typically 400 to 1,000 bar \u2014 by a piston (plunger) in a cold-chamber machine. The cavity fills in a fraction of a second, and the water-cooled die extracts heat so quickly that cycle times are measured in tens of seconds to a few minutes. The result is extremely thin walls, tight dimensions (\u00b10.1 mm) and an excellent as-cast surface finish. However, the very filling mechanism that makes the process fast also traps air, giving HPDC parts some internal porosity that limits ductility and prevents subsequent heat treatment. HPDC is the most widely used casting process \u2014 roughly half of all light-alloy castings are made this way \u2014 and it is economical only at high volume, typically requiring at least 10,000 parts per die and ideally far more.<\/p>\n<h1><span class=\"ez-toc-section\" id=\"Head-to-Head_Comparison\"><\/span>Head-to-Head Comparison<span class=\"ez-toc-section-end\"><\/span><\/h1>\n<p>The table below summarises the key differences that matter when you are selecting a process.

In HPDC, air is almost inevitably trapped during the ultra-fast fill. This porosity lowers ductility to under 3%, weakens the part, and makes it non-heat-treatable: the entrapped gas expands and causes blistering during solutionising. Gravity casting, filled smoothly under gravity, produces a dense, sound, leak-tight structure with far less porosity, and it can be machined with no porosity breaking the surface. For this reason, gravity castings are the more reliable choice wherever pressure tightness and structural integrity matter.<\/p>\n<p>At the same time, HPDC has its own strengths. Its smooth as-cast skin gives excellent fatigue life, provided that skin is not machined away. A machined pressure die casting may even be stronger than a permanent-mold casting, but the permanent-mold (gravity) part is generally the more reliable choice because of its lower porosity. In short: HPDC wins on thin walls, speed and surface finish; GDC wins on integrity, strength, heat treatability and machinability.<\/p>\n<h1><span class=\"ez-toc-section\" id=\"Cost_Tooling_and_Production_Volume\"><\/span>Cost, Tooling and Production Volume<span class=\"ez-toc-section-end\"><\/span><\/h1>\n<p>Tooling tells the story of where each process pays off. HPDC dies must withstand large injection forces, so they are made of stronger hot-work tool steel and are more expensive. Gravity dies use pearlitic cast iron or low-alloy steel and cost less. But HPDC is far faster, so at very high volumes the per-part cost is lower. Gravity casting, with its longer cycle times measured in minutes, is economical over roughly 1,000 to 100,000+ parts per year \u2014 volumes where a single high-pressure die would be overkill and multiple dies would be needed.<\/p>\n<p>It is also worth remembering that a casting is only the beginning. If the part must be machined, the porosity of an HPDC casting can show up on machined faces, driving up scrap and rework; a sound gravity casting machines cleanly with no surface porosity. When you add in the cost of rejects, heat treatment and pressure testing, the apparent price difference between the two processes narrows considerably \u2014 which is why many buyers choose gravity for parts they cannot afford to fail.<\/p>\n<p>A simple rule of thumb: the thinner the wall, the tighter the tolerance and the higher the volume, the more <a href=\"https:\/\/www.thediecasting.com\/high-pressure-die-casting\/\" target=\"_blank\" rel=\"noopener\">HPDC<\/a> pulls ahead; the stronger, sounder, heat-treatable and more complex the part, the more GDC wins. Many professional foundries offer both processes and can advise on the best match for your specific geometry, volume and application.<\/p>\n<h1><span class=\"ez-toc-section\" id=\"Frequently_Asked_Questions\"><\/span>Perguntas frequentes<span class=\"ez-toc-section-end\"><\/span><\/h1>\n<p><strong>Which process produces stronger castings?<\/strong><\/p>\n<p>Gravity die casting generally delivers higher mechanical properties and ductility, and it allows heat treatment.
