Castings


Most of the items at home are made from the casting industry. Kitchen items, bedroom objects, dining room appliances and other tools and gadgets are made out of castings. The casting process isn’t as easy as buying the product – in fact the whole process of manufacturing a product made out of the casting method is very complicated. Castings play important roles in our daily lives so despite the complicated process, there are many manufacturers that strive to create castings and process the casting mechanism.

There are many different types of casting processes and each of these processes belong to one of two groups – the cold forming process and the hot forming process. The hot forming process includes casting methods like extrusion, forging, centrifugal casting, investment casting, full mold casting, permanent and gravity die casting, sand casting, plaster mold casting and shell mold casting. The kind of casting used will depend on the products to be casted.

On the other hand, cold forming process includes casting methods like squeeze casting, pressure die casting, burnishing, cold forging, coining, impact extrusion, peening, thread rolling and sizing. In the cold casting process, urethane resin is mixed with metal powder and pouring the mixed product into mold for a cast that will appear like sold metal. Metal powders can be bronze, brass, nickel, silver, aluminum and copper – each of which will be used for different purposes.

Each casting process differs by the equipment used, amount of metals needed throughout the process, the minimum amount of finished products and the supposed finished product. Before the castings are processed, there are many things to consider like the finance and budget of the manufacturing company, the skills of the employees, the price of the total amount needed for the metals to be used, what kind of metal is best for the finished product, what suppliers to use for the metals and which manufacturer to trust with the process itself.

The metals to be used will also be chosen based on their qualities such as its price, its durability, stability, shape, weight, tolerance, thickness and texture. There are also some manufacturers that will select metals based on special quality requirements like magnetism, stress distribution and corrosive elements. Other factors that will be playing important roles in manufacturing casted products are the adequacy of the protection and packaging of the finished product, shipping constraints, and regulations in the final product, protective coatings and the required shelf life for the castings.
