Casting play an essential process in most of our items at home. Whether they are appliances, decorations, furniture and fixtures or even just collectible items, casting metal has become a widely popular manufacturing process. However, production companies cannot just cast a product because these processes take time and a lot of money to pull off. In fact, casting processes are usually major productions as the costs can be uneconomically friendly without batch processing. The good thing about casting is that there are various ways to cast metal and each of these modes have their own benefits.
Sand casting, the mechanism used to produce equipment with bronze, iron, aluminum and brass, is done by spilling molten metal into casts which are made of sand. The sand is a major factor in retaining the shape and also provides manufacturers a way to produce large casts without having to incur high costs. The biggest advantage of this method is that unlike other casting processes, it incurs relatively lower costs to pull off. This technique doesn’t require many skills from the workers, either, making it a good opportunity to provide employment easily and in cheaper rates.
Die casting, on the other hand, is a process wherein the molten metal is forced into steel molds under high pressure. The molds or dies, are designed to create various shapes and is likely to be more accurate than other methods. The parts produced in a die casting process are redefined once the process is over. The parts are sharpened, smoothed or reshaped to form specific parts. While this is the best method in casting metal, this is also the most expensive, depending on the metal to be used. Even so, die cast products are widely used everywhere – coins, faucets, connectors, automobile parts and even toys. This process allows a production of complex shapes and has a higher possibility of being strong and more durable.
Investment casting, formed from lost-wax casting or one of the oldest metal casting processes. Products formed by this method have great surface quality and are accurately dimensional. This method is usually used to form surgical equipments, geometrics with complex figures and important metals. For work with essential details and are generally small, the investment casting process is highly recommended. However, nowadays, investment casting is also used to produce aircraft door frames and other more complicated items that cannot be done with die casting. Investment casting costs higher per metal but has cheaper equipment costs.
