Process 3: Generally, according to the production requirements of the product, it is divided into several processes such as stamping, hydraulic processing, die-casting, and corrosion treatment. ( Stamping: Install the heat-treated molds onto the press table, and transfer the patterns onto different materials such as copper or iron sheets. Using the pre-made cutting molds, use the stamping machine to press the products down according to their shapes.) ; (Hydraulic: Using the pre-made die molds, the product is shaped according to its design and then punched off using a press. Next, the punched product is placed on the press machine to imprint the pattern.) ; (Die Casting: Die casting is a casting method in which molten alloy liquid is poured into a die cavity, and is rapidly filled by a steel mold to cause the alloy liquid to solidify under pressure and form a casting. The main characteristic that distinguishes die casting from other casting methods is high pressure and high speed: The process involves first creating a photoresist film, then printing the patterns on the film onto different materials such as copper or iron, and finally placing the film in a solution of the appropriate acid for the pattern to be corroded.)
