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 following issues need to be paid attention to when making molds. 1. Don't just focus on product design and ignore mold manufacturing. When some users develop products or trial production of new products, they often only focus on product research and development at the initial stage, neglecting the communication with the mold making unit. After the product design plan is initially determined, there are three benefits to contact with the mold manufacturer in advance.

The field of CNC machining has passed a long-term development trend, and at this stage already has a complete set of specifications, whether it is machine tool spindle, CNC blade socket or operating system software. In contrast, the 3D printing industry lacks such norms at this stage, and the creation of standards is usually not achieved in a short period of time.

Powder metallurgy processing is the production of various metal powders as raw materials, and then through a series of pressing, injection, sintering, post-processing and other processes to make the final desired product parts processing technology, powder metallurgy can process complex products in large quantities , At present, it has replaced the traditional forming processing method in various fields, and the new generation of near-net forming technology makes powder metallurgy processing more popular.

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.
