Gravity die casting is a metal casting method in which the molten metal is directed to fill a reusable metal mold, using the force of gravity alone and no external pressure. The process yields powerful, precise and finely finished metal components and this is the reason why automotive, aerospace, and machinery industries are using it […]
Heat treatment of steel is one of the most important decisions behind the final performance of a part. It affects hardness, strength, toughness, wear resistance, dimensional stability, machinability, and fatigue behavior. For a buyer, that means the steel grade alone is never the full story. Two parts made from the same steel can perform very
Heat treatment of aluminum is often treated as a material note on the drawing, but for buyers it is really a performance decision. It affects strength, hardness, ductility, dimensional stability, corrosion behavior, and machinability. Two parts made from the same aluminum alloy can behave very differently if one is delivered in an annealed or as-fabricated
Porosity is one of the most common reasons a casting that looks acceptable at first becomes expensive later. It may show up as a cosmetic defect, but more often it becomes a machining problem, a leak problem, a fatigue problem, or a quality-acceptance problem. That is why buyers should not treat casting porosity as a foundry-only
Un cierre frío es uno de esos defectos de fundición que pueden parecer menores en la superficie y aun así convertirse en un grave problema comercial más adelante. A menudo aparece como una línea similar a una costura, una marca redondeada similar a una grieta o una interfaz débil donde dos frentes de metal se encontraron pero no se fusionaron completamente. En servicio, esa línea puede comportarse
En el mundo de la fabricación de alta precisión, desde componentes complejos de UAV hasta intrincados implantes médicos, el éxito comienza mucho antes de que se vierta la primera gota de metal fundido. Comienza con la cera. En el proceso de fundición a la cera perdida (o de inversión), el modelo de cera sirve como el "alma" de la pieza metálica final. Cada detalle, textura y dimensión de la pieza
