? Powder forming press is a kind of precision machinery used in powder metallurgy. Through the forming space of the upper die and the lower die, the alloy powder in the die is pressed by high pressure to obtain the required parts. It is a new application of science and technology, and it can get precision parts with as little mechanical processing as possible. In order to make the precision press work safely and efficiently, the servo controller is used to control the action of the forming press. In the servo controller, there is a programmable controller PLC to realize servo control, and the precise control of the press can complete the actions of opening and closing the die, aligning the die, automatically feeding, shearing the flash and automatically pushing the material according to the set working steps. Powder servo molding machine is an indispensable molding machine in modern industry.
