The main difference between the metal powder pressing and warm pressing technology and the traditional molding process is that the powder and the mold are heated to a certain temperature during the pressing process, and the temperature is usually set within the range of 130~150 °C. The density of iron-based powder metallurgy parts is increased by 0.15-0.4g/cm3, and the relative density of powder compacts can reach 98-99%.
In this process, in order to give full play to the isothermal pressing densification mechanism of particle rearrangement and plastic deformation during the pressing process, it is often necessary to optimize the design of the raw material powder (such as the selection of shape and particle size composition), and the metal powder compression molding process, through annealing or Diffusion annealing to improve powder plasticity, and high temperature lubricant (usually 0.6 wt%) is incorporated into the powder.
Powder press forming, also known as powder press forming, is used to press compacts of various oil-containing bearings, powder metallurgy anti-friction products, powder) Taijin mechanical structural parts, etc. through a four-axis hydraulic press. Pressing complex-shaped parts has a higher degree of mechanization and automation.
CIM ceramic injection molding is a near-net-size plastic molding method developed on the basis of polymer injection molding technology. The basic process of smart wearable ceramic injection molding mainly includes four stages: feed preparation, injection molding, degreasing and sintering.
Metal powder press forming, also known as powder press forming, is used to press compacts of various oil-impregnated bearings, powder metallurgy anti-friction products, powder) Taijin mechanical structural parts, etc. through a four-axis hydraulic press, and the design of presses and molds is continuously improved. It can suppress parts with complex shapes and has a higher degree of mechanization and automation.
