Casting is a specialized procedure for creating different metal parts in various shapes and sizes. The process of metal casting involves the use of metals like aluminum, iron, bronze, magnesium alloys etc to mold into specified shape, size, and thickness. This procedure involves pumping the molten fluid into the mold and allowing it to cool to get the shape of the mold. Some of the major elements of the casting process include patterns, molds, cores and parts.
The process of casting is mostly used for creating parts from metals like aluminum, steel, and copper. It offers one major advantage of quality in the finished products. Casting is one of the most widely used processes by all types of metal manufacturing industries to make quality products with good finishing. Many die casters in Mexico use two of the most popular casting methods, permanent mold casting and die-casting. Below are some of the differences between permanent mold casting and die-casting.
Permanent Mold Casting
The process of permanent die-casting involves use of two molds. These molds are joined together and the heated metal is molded when poured into the molds. Some of the metals used in permanent mold casting are aluminum, zinc, tin and lead. After the molten metal is cooled down, the parts of the mold are then separated to get the finished product. Either the products can be removed manually or using a flash grind, as the finished products might contain metal extrusions. The permanent mold casting process is mostly used to mold non-ferrous metals. Acetylene soot is coated to the steel cavities to extend the life of the tools.
Die-casting is the process employed for molding metals using high or low pressures. Previously, low-pressure methods were utilized for die-casting. However, Mexican die casters use high-pressure die casting for the creation of complex shapes and products. The high-pressure method ensures that the finished products have excellent precision while offering smoother finishing.
The process of die-casting may differ according to the desired results. For a single component, the casting requires only a single cavity. Multiple parts, on the other hand, require multiple cavities for the casting mold. The Die casting process ensures that the metals remain pore free and highly durable.
