Raw materials and feeding
Metal powder should be fine, spherical, and of high purity, with a low oxygen content.
The powder loading capacity should be controlled at 55% to 65%. If it is too high, it is prone to material shortage, and if it is too low, it is prone to deformation.

Key precautions and detailed instructions for metal injection molding
Material selection and feeding quality control: The particle size (usually 1-20 μ m fine powder), morphology, and purity of metal powder directly affect the sintering density and feeding flowability; The formula of the adhesive (thermoplastic resin, wax, etc.) needs to match the powder characteristics to ensure the bonding and molding effect. The mixing process requires temperature and speed control to ensure uniform feeding composition and stable rheological properties. At the same time, indicators such as feeding uniformity and viscosity need to be tested.
