Due to the different shapes and many details of car steering wheels, car steering wheels are generally made with the help of die-casting molds. There are many classifications of die-casting machines, their working methods, and classification methods of die-casting machines. According to the scope of use, they are divided into general-purpose die-casting machines and special-purpose die-casting machines. Die-casting refers to a casting method in which liquid metal is filled into a mold cavity under high pressure and high speed conditions, and cooled and formed under high pressure to form the desired product.
