Description
Bailiang Zhuang heads a 2026 study using ultrasound to improve frozen sand molds for cleaner metal casting. Frozen molds avoid polluting resin binders, but uneven moisture during mixing leaves weak wet and dry patches.
An ultrasound-assisted mixing platform spread water evenly through tiny liquid bridges between chromite sand grains. Ice then grew fine and even, weaving a linked sand-ice web that resisted frost swelling and cracks. Pulling and crushing strengths of the frozen forms rose markedly. The method could speed adoption of digital frozen sand casting in aerospace and machine building while cutting pollution.
