A&B Die Casting is a global industry leader in precision aluminum and zinc die castings. We got our start in 1945 by Ben Danthe and today we continue to be a family owned company located in Hercules, California. We focus on producing low to medium volumes of high quality products at competitive prices. Our employees have a flexible, can-do attitude and take on challenging jobs that other die companies turn away. As an ISO 9001:2008 certified company, we focus on providing high quality products and innovative solutions for all of our customer’s needs.
Sand has many uses. I know it’s used as a material in sand castles and CPU chips, but I never would have guessed it’s used for certain types of metal casting. Actually, sand casting is the most common type of casting done today. According to a survey in 2003, seventy percent of metal castings are done by sand casting. Products made this way include metal tools, car parts and plumbing equipment. Sand is used because it can apparently withstand very high temperatures because it’s a refractory material.
In a 1988 paper released by NASA and the Georgia Institute of Technology, Soil Transport Implement, researchers presented an outline for the design of a component that would protect a vehicle that was being designed for moon expeditions. At that point in NASA’s history, the moon landing was becoming a comparatively distant memory. The Challenger disaster was only half a decade in the past, and the Rogers Commission had determined that NASA’s institutional culture was lacking and may have been responsible for the faults that contributed to the disaster.
The North American Die Casting Association says on its website that it considers metal casting to be “America’s most fundamental industry.” It’s not surprising that a metal casting trade association would describe die casting services as fundamentally important, and it’s likely that other trade associations for other sectors of industry would dispute the NADCA’s claim. But there’s no denying that casting is an essential element in our industrial infrastructure.
Zinc is considered to be one of the most easily die cast metals. It is highly ductile, has high impact strength and minimizes die wear. For these and other reasons, zinc is a very popular die casting material. Understanding zinc’s popularity as a die casting material first requires an understanding of the die casting process. Let’s review that process quickly. Die casting is the process by which molten metals are forced into a die in order to give them shapes. Dies are specially-designed cavities that are designed to create specific metal products. The process begins when a metal is heated until it becomes molten. Then, depending on the die casting method, the molten material is either directly drawn into the casting mechanism or is transported into it by other equipment. After that point, the molten metal is forced into the die cavity by a piston. It becomes pressurized within the cavity, which causes it to closely form around the contours of the die, causing it to take the shape of the die. At the end of the process, the metal is allowed to cool and harden, after which point it is ejected from the die and sent for additional processing if necessary.
