Die forging is a method of forming on a forging die developed on the basis of free forging and die forging in order to solve the problems of low productivity and poor precision of free forging, and to achieve the needs of large-scale and specialized production of forgings. Die forging is the abbreviation of model forging. The forging die (forging die) is generally composed of an upper die and a lower die. The upper and lower dies of the forging die are respectively fixed on the hammer head and the die pad. or die groove), the shape and size of the cavity of the groove is the same as the shape and size of the forging. During die forging, the blank is placed on the lower die, and the upper die moves down with the hammer (or slider) to close the die (one or more times) to hit the blank. Under the action, plastic deformation is generated and the groove is filled, and finally a forging with the same shape as the groove is obtained.

The materials for making stamping dies include steel, hard alloy, steel-bonded hard alloy, zinc-based alloy, low melting point alloy, aluminum bronze, polymer material and so on. Most of the materials for manufacturing stamping dies are mainly steel.

The raw metal or plastic material used for the part is as important as how the part is machined; choosing the wrong one can unnecessarily increase the cost of the part. For example, titanium, the darling of superalloys and aerospace, is difficult to machine, and parts made from it are almost certainly more expensive than parts made from aluminum or stainless steel. What's the point? If it's not really needed, choose a cheaper metal.

Unsafe factors in machining process. In the process of machining magnesium alloys, the chips and fine powders produced have the risk of burning or exploding.

From the 1950s to the present, injection molding has dominated consumer product manufacturing, giving us everything from action figures to denture containers. Despite its incredible versatility, injection molding does have some design limitations.

Generally, injection molded products are formed and processed through corresponding molds. After an injection molded product is formed and solidified, it is taken out from the mold cavity or core, commonly known as demoulding. Due to molding shrinkage and other reasons, plastic parts are often wrapped tightly around the core or trapped in the mold cavity.
