Manufacturing and Processing of Cast Iron
The manufacture of cast iron is a tightly controlled metallurgical process, not a simple melting-and-pouring operation. Its final performance depends on a sequence of linked steps in which chemical composition, melt cleanliness, inoculation or treatment, mold design, cooling rate, and post-processing all interact. Because cast iron is highly sensitive to carbon behavior and graphite...

Surface finishing for precision castings
Shot / bead / sand blasting — fast, uniform matte finish; removes shell wash, sand, scale; good pre-step for plating or painting. Use small glass beads for smoother results; coarse grit for scale removal. Vibratory / barrel (mass) finishing — excellent for burr removal and edge radiusing of many small parts; economical for batches; finish depends on media + cycle time....

What Is Cast Aluminum?
1. Basic definition Cast aluminum refers to aluminum (or aluminum-based alloys) that have been shaped by pouring molten metal into a mold where it solidifies into the desired geometry. Unlike wrought aluminum (rolled, forged, or extruded and then machined), cast aluminum is formed directly from the liquid state, which allows economical production of complex shapes, thin walls and...

EN-GJS-400-15 Ductile Iron
1. What is EN-GJS-400-15 Ductile Iron? EN-GJS-400-15 is a standardized grade of ductile (spheroidal graphite) cast iron under the European standard family (EN 1563 / EN symbolic system). The designation breaks down as: GJ(S) or GJS — G = iron (cast), J = spheroidal graphite (nodular/ductile) structure, S indicates spheroidal graphite (sometimes the S is omitted in shorthand...

What Is Permanent Mold Casting?
Permanent mold casting (also called gravity die casting when gravity fills the mold) is a family of processes in which a reusable, usually metallic mold (the “permanent” mold) is used to produce castings. Unlike expendable-mold methods (sand, investment, lost-foam), the mold remains intact and is reused for many cycles. Molten metal is poured or forced into the mold cavity,...

Application of 314 Stainless Steel
Austenitic 314 stainless steel (UNS S31400, EN 1.4841, X15CrNiSi25-21) is a chromium-nickel-silicon alloy engineered for continuous high-temperature service. Compared with 310/310S, 314 contains elevated silicon and robust Cr–Ni content that together improve oxidation and scaling resistance and give better creep strength at elevated temperatures — making 314 a go-to material for...

Surface Treatments & Non-Stick Systems of Cast Aluminum Cookware
Cast aluminum cookware is widely favored in household and commercial kitchens due to its excellent thermal conductivity (120–150 W/(m·K)), lightweight properties (density 2.7 g/cm³), and good formability for complex shapes. However, pure cast aluminum has inherent drawbacks: poor corrosion resistance (prone to oxidation and pitting in acidic/alkaline environments), low...
