Metal injection molding is a near-net-shape manufacturing process that is suitable for producing small and complex three-dimensional structures, as well as products with special performance requirements. Metal injection molding is a new near-net-shape technology developed by introducing modern plastic injection molding technology into the field of powder metallurgy. Any metal or alloy that can be made into powder can be manufactured using this method, to obtain metal parts with complex shapes, uniform microstructures and high-performance, high-strength and high-precision properties. Let's explore the process and advantages of metal injection molding technology below.
Metal injection molding mixes various metal fine powders (generally less than 20um) with a predetermined binder in a certain ratio to form a material with rheological properties, which is injected into the mold cavity by an injection machine to form a part blank. After the part is separated from the binder, various metal parts can be obtained by high-temperature sintering.
Metal injection molding technology has advantages that cannot be compared with traditional powder metallurgy, machining and precision casting methods:
Unrestricted structure: Complex metal parts can be directly formed like plastic production.
Easy mass production: Suitable for large-volume continuous production, technical advantages will be highlighted for products with large-volume requirements.
Reliable physical properties: The product has a uniform structure, good density, and good surface finish.
Wide selection of materials: Stainless steel, soft magnetic alloys, iron-nickel materials, tungsten alloys, hard alloys, tool steels, etc.
Significant cost reduction: In the case of batch production of complex structural parts, costs can be greatly reduced.
Metal injection molding technology has unique advantages in producing large and complex parts. Designers should focus on designing complex 3D shaped parts to fully utilize metal powder injection molding technology, reduce production costs, and improve product performance.
Metal injection molding can produce metal parts of various complex shapes with consistent density and properties that are isotropic. Powder metallurgy provides considerable freedom in product design, and it can approach very high-precision parts, even if the relative density can reach 95% through solid-state sintering. Its performance can also rival forged materials, especially with good dynamic performance.
