In mechanical design and manufacturing, the edge treatment of components directly impacts their performance, service life, and appearance. Although both fillets and chamfers are common edge finishing methods, they differ in stress distribution, assembly convenience, safety, aesthetics, and machining cost. Choosing appropriately between fillets and […]

The fundamental difference between alloy steel and stainless steel lies in their core purpose. Stainless steel contains at least 10.5% chromium to form a self-healing passive oxide layer. This prioritizes long-term corrosion resistance and cleanliness; its essence is “stainlessness,” even at the cost of some

Lost foam casting is a precision casting process that utilizes expandable polystyrene (EPS) foam to create the pattern, which is then embedded in binder-free dry sand. During pouring, the heat from the molten metal causes the foam pattern to vaporize instantly, allowing the molten metal to fill

Plaster mold casting is a precision metal forming process that utilizes disposable gypsum molds to manufacture complex, high-tolerance non-ferrous metal components (such as aluminum, copper, and zinc alloys). Leveraging the exceptionally fine particle size of the plaster slurry, this process perfectly replicates intricate details and achieves

Shell Mold Casting (also known as the “Croning Process”) produces high-precision metal parts by creating a thin-walled (9-20mm), rigid “shell” mold through the combination of resin-coated sand and a heated metal pattern. This process can achieve casting dimensional tolerances within ±0.25mm and surface roughness as

Investment Casting (also known as lost-wax casting) is a precision forming process used to produce near-net-shape, highly complex metal parts. This process uses a sacrificial wax model to create a ceramic shell, achieving casting tolerances of ±0.1 mm and a surface finish of 1.6-3.2 micrometers.

Sand casting is a manufacturing process where molten metal is poured into a disposable mold made of sand. The core steps include: pattern making, mold making, mold assembly, pouring, cooling and shakeout, cleaning, and fine processing. This process is suitable for all metal alloys and

Aluminum is a cornerstone of modern manufacturing, essential for components made through casting, extrusion, rolling, and other processes. When sourcing for your project, the fundamental question is: how much is aluminum per pound? As of the end of October 2025, the answer is multifaceted. The

Casting is a fundamental manufacturing process where molten metal is poured into a pre-formed mold cavity. After cooling and solidification, it forms a final product known as a “casting.” Currently, the most common casting methods include: sand casting (most versatile), investment casting (highest precision), die
