How to balance lightweighting and high strength? Gravity-cast aluminum worm housings solve industry challenges.

Mechanical Worm Housing Gravity Casting Aluminum Parts Become a New Choice for Equipment Upgrades

Reporter Doubao, September 26, 2025: In high-end equipment such as new energy vehicle transmission systems and port cranes, "reducing weight without sacrificing quality" remains a core goal for engineers. Recently, mechanical worm housings (gravity-cast aluminum parts), crafted using gravity casting, have achieved a breakthrough in mass production, leveraging their unique advantages. This provides a new solution for equipment lightweighting upgrades and has attracted widespread attention in the industry.

Process Innovation: Gravity Casting Empowers Aluminum Housings with Multiple Advantages

As the core load-bearing component of a worm drive system, the worm housing must withstand the continuous mechanical stresses of the transmission process while also meeting corrosion resistance requirements in various scenarios. Mechanical Worm Housing Gravity Casting Aluminum Parts utilizes a gravity casting process, allowing molten aluminum alloy to naturally fill the mold cavity under the influence of gravity, solidifying evenly to form the finished product, ensuring product quality from the very beginning.

"This process allows the molten metal to fully fill mold details. Combined with vacuum degassing technology, it reduces the porosity defect rate in the casting by over 60%," said Mr. Li, Process Director of a machinery manufacturing company. These aluminum housings are made of the high-performance AlSi10MnMg alloy, which has been tested to demonstrate a tensile strength of 320 MPa and a surface finish of Ra1.6, meeting assembly requirements without the need for secondary processing. Compared to traditional cast iron housings, they are over 40% lighter and demonstrate excellent corrosion resistance in salt spray tests, making them suitable for harsh working conditions such as those found in mining and chemical industries. Market Drivers: Lightweight Demand Drives Explosive Product Growth

The 2025 Aluminum Casting Industry Report shows that the global aluminum casting market is expanding at a compound annual growth rate of over 5%, with lightweighting of automobiles and upgrades to high-end equipment being the core drivers. Mechanical Worm Housing Gravity Casting Aluminum Parts addresses this market pain point and has achieved large-scale application in multiple sectors.

In port logistics equipment, a reducer using this aluminum housing to drive an 800-meter belt conveyor reduces system starting current by 21%, saving up to 42,000 kWh annually. In new energy vehicle drivetrains, its lightweight design reduces vehicle energy consumption by 8%-10%, meeting automakers' demand for increased range. "In the third quarter of this year alone, our orders for this type of product increased by 72% year-on-year, primarily from new energy vehicle and smart equipment companies," said a sales manager at a foundry.

Industry Trend: Intelligent Upgrades Drive Quality Breakthroughs

Currently, mechanical worm housing gravity casting aluminum parts are upgrading towards intelligent production. Some leading companies have implemented finite element analysis (FEA) to optimize the layout of housing ribs, reducing wall thickness by 12% while maintaining rigidity, further reducing weight and increasing efficiency. Furthermore, by incorporating technologies such as robotic casting and online X-ray inspection, they have maintained a stable product qualification rate above 99.2%.

Industry experts point out that with the advancement of the "Made in China 2025" strategy, the aluminum casting industry is transitioning from traditional manufacturing to intelligent manufacturing. Mechanical worm housing gravity casting aluminum parts, as a typical example, is a leading example, and its technological upgrade path will provide a reference for the entire industry. In the future, with the integration of new alloy material research and development with 3D printing prototyping technology, this type of product is expected to achieve breakthroughs in high-end fields such as aerospace.
