In recent years, with the continuous upgrading of electric vehicle manufacturing technology, Mega die Casting, as a new way of manufacturing automobile structures, has gradually become the focus of heated discussion in the industry. Its core concept is to complete the die-casting of structural parts originally composed of dozens or even hundreds of parts on a super-large die-casting machine at one time, thereby greatly simplifying the process, improving manufacturing efficiency, and reducing the cost of the whole vehicle. <h2>Mega Die Casting: The First Large-Scale Breakthrough in Automotive Manufacturing</h2>Since 2020, Tesla has used giant die-casting parts in the rear chassis of the Model Y model to replace more than 70 original welded parts. The production of this large die-casting part relies on the 9,000-ton die-casting equipment provided by the IDRA Group, which helps it achieve significant advantages in structural weight reduction, manufacturing cycle and vehicle cost. According to Automotive News data, Tesla's vehicle manufacturing time has been shortened by more than 10%, and the cost of a single vehicle has dropped by about US$500.<h3>More car companies join the battle </h3>Not only Tesla, Mega die Casting has become a consensus in the field of automotive die-casting. In its "Trinity" electric vehicle project, Volkswagen plans to adopt an Mega die Casting rear body structure. New Chinese forces such as Weilai, Xiaopeng, and Xiaomi have also invested in the construction of large-scale die-casting production lines. For example, Weilai cooperated with Ningbo Xusheng to introduce IDRA giant die-casting equipment, and Xiaomi Automobile introduced large die-casting machines for chassis die-casting tests during the research and development stage. BYD has developed its own 6,000-ton die-casting equipment and entered the core link.<figure id="figure-kbfc4x4lp1m9jiznk5"><img id="kbfc4x4lp1m9jiznk5" src="https://media.gettyimages.com/id/1496042469/photo/vehicle-skeleton-door-mounting.jpg?b=1&amp;s=2048x2048&amp;w=0&amp;k=20&amp;c=v34P4y6kfKJMVt6vobdZRCQY2Y-UR2ng_oFnq0Zh0CE=" alt="Mega die casting" title="Mega die casting" class="object-cover bg-gray-100 rounded-2xl md:rounded-3xl lg:rounded-4xl" style="aspect-ratio: 16/9; object-position: center center;" data-corners="large" data-aspect="16:9" data-caption="" data-positionx="undefined" data-positiony="undefined" data-fullwidth="false" data-mce-src="https://media.gettyimages.com/id/1496042469/photo/vehicle-skeleton-door-mounting.jpg?b=1&amp;s=2048x2048&amp;w=0&amp;k=20&amp;c=v34P4y6kfKJMVt6vobdZRCQY2Y-UR2ng_oFnq0Zh0CE=" data-mce-style="aspect-ratio: 16/9; object-position: center center;"></figure>According to research organization Strategy Analytics, by 2029, more than 25% of electric vehicles in the world will adopt an Mega die Casting architecture, and the application rate in the Chinese market is expected to exceed 30%. This shows that the penetration rate of Mega die Casting in the field of automotive die-casting will continue to rise. <h3>Far-reaching impact on the die-casting industry&nbsp;</h3>The promotion of Mega die Casting brings new challenges and opportunities to the entire die-casting industry. First, the demand for die-casting equipment has been upgraded. 9,000-ton super-large die-casting machines, mold temperature control, vacuum systems, etc. all need to be updated. Secondly, the complexity of mold design has increased significantly. Due to the large wall thickness variation and long flow distance of large die castings, traditional mold manufacturing and cooling processes are difficult to cope with, and must rely on advanced CAE simulation and high-precision processing technology. In addition, integrated die casting requires extremely high material performance and quality consistency. Most companies choose to use high-ductility aluminum alloy materials (such as Aural series, ADC12 upgraded version), and put forward higher standards for smelting and degassing processes. As automotive die casting gradually extends to structural parts and key bearing parts, material research and development and casting process synchronization iteration have also become the core competitiveness of die casting manufacturers. <h3>Reshaping the supply chain and production methods </h3>While simplifying the manufacturing process, integrated die casting also breaks the original parts supply ecology. Tier 1 suppliers face the risk of functional modules being integrated and must transform to system development and integration capabilities to maintain competitiveness. At the same time, the vertical integration trend of vehicle manufacturers in die casting, molds, testing and other links has increased, and the requirements for core process control have been greatly improved. According to an industry survey published by China Diecasting, among the leading vehicle manufacturers that have implemented Mega die Casting, the average number of parts has been reduced by 40%-60%, labor costs have dropped by 20%-30%, the supply chain level has been compressed by up to two levels, and the space efficiency of a single vehicle in the manufacturing plant has increased by more than 50%. <h3>Conclusion</h3>Mega die Casting is not only an innovation in structural technology, but also a reconstruction of manufacturing concepts, production line layout and supply chain logic. For die-casting companies, this is a window period for industrial transition and an important gateway to determining future survival and growth.SHD Precision Diecasting has extensive experience in large-scale die casting manufacturing and can provide automotive <a data-mce-href="https://shd-diecasting.com/contact" href="https://shd-diecasting.com/contact">Mega die casting</a> customers with integrated solutions from mold design, material selection to mass production.

Why Die Cast Zamak is Ideal for High-Precision Manufacturing

Gravity die casting is one of the most trusted and widely used metal casting methods for manufacturing medium to high-volume precision components. As industries demand stronger, more dimensionally stable, and cost-effective parts, gravity die casting continues to deliver consistent performance—particularly for aluminum and other non-ferrous alloys.This article explains how the gravity die casting process works, its advantages, ideal applications, and why it remains a popular choice among OEM manufacturers.<h2>What is Gravity Die Casting?</h2> Gravity die casting—also known as permanent mold casting—is a metal casting process in which molten metal is poured into a reusable steel or iron mold under the influence of gravity alone, without external pressure or vacuum.The mold, usually pre-heated and coated with a refractory layer, allows molten metal to fill the cavity smoothly, and solidify under controlled cooling conditions. This method is particularly well-suited for metals like:-Aluminum alloys-Magnesium alloys-Copper-based alloysUnlike sand casting, gravity die casting uses metal molds, which offer better dimensional control and surface finish. Unlike high-pressure die casting, it does not require complex machines or extremely high injection pressure, making it cost-effective for medium-run production with high quality.<figure id="figure-87zwgvx6epm8sezi49"><img id="87zwgvx6epm8sezi49" src="https://media.gettyimages.com/id/2163633009/photo/titanium-alloy.jpg?b=1&amp;s=2048x2048&amp;w=0&amp;k=20&amp;c=mfbcrliEatcpOqV-ECrdVibtXe2qtG8C03oQHpRpNsQ=" alt="titanium alloy" title="titanium alloy" class="object-cover bg-gray-100 rounded-2xl md:rounded-3xl lg:rounded-4xl" style="aspect-ratio: 3/2; object-position: center center;" data-corners="large" data-aspect="3:2" data-caption="" data-positionx="undefined" data-positiony="undefined" data-fullwidth="false" data-mce-src="https://media.gettyimages.com/id/2163633009/photo/titanium-alloy.jpg?b=1&amp;s=2048x2048&amp;w=0&amp;k=20&amp;c=mfbcrliEatcpOqV-ECrdVibtXe2qtG8C03oQHpRpNsQ=" data-mce-style="aspect-ratio: 3/2; object-position: center center;"></figure><h3>Advantages of Gravity Die Casting</h3> Gravity die casting offers multiple benefits for manufacturers requiring both performance and consistency:1. Superior Mechanical Properties Parts made with gravity die casting generally have fewer internal voids and better grain structure compared to sand-cast parts. This results in higher tensile strength, fatigue resistance, and structural integrity—especially when combined with proper thermal treatment.2. Dimensional Accuracy Gravity die castings typically achieve better dimensional precision than sand castings. Tolerances of ±0.1mm or better are achievable with high-quality molds and controlled pouring processes.3. Excellent Surface Finish Gravity cast parts require minimal machining thanks to smoother surfaces and clean casting edges. Typical surface roughness can range from Ra 3.2 to Ra 6.3μm, depending on alloy and mould condition.4. Reusable Molds Since permanent molds can be used for thousands of cycles, this method supports cost-efficient mid- to high-volume production. The use of automated pouring and controlled cooling further improves repeatability.<h3>Common Applications of Gravity Die Casting</h3> Gravity die casting is widely adopted in the following industries:Automotive: Engine brackets, cylinder heads, suspension parts, housingsAerospace: Lightweight structural components, brackets, heat sinksIndustrial Machinery: Gearboxes, pump housings, valve bodiesLighting &amp; Electronics: LED heat sinks, enclosuresSmart Appliances: Coffee machine frames, induction cooker housingsThe method’s balance of strength, precision, and cost-efficiency makes it ideal for components requiring mechanical performance and consistent form.<h3>Suitable Materials for Gravity Die Casting</h3> The most commonly used materials in gravity die casting include:Aluminum alloys (e.g., A356, ADC12) – excellent for lightweight and corrosion-resistant partsMagnesium alloys (e.g., AZ91D) – ultra-lightweight with good dimensional stabilityBrass and bronze – ideal for decorative and corrosion-resistant componentsCopper-based alloys – used for fittings and conductive applicationsMaterial selection depends on mechanical requirements, conductivity, corrosion resistance, and intended usage environment.<h3>Partner with SHD Precision Diecasting for Gravity Casting Projects</h3> At SHD Precision Diecasting, we provide professional gravity die casting services for clients across the automotive, consumer electronics, lighting, and industrial equipment sectors.
