Metal powder injection molding

Metal powder injection molding: the future of precision manufacturing

In manufacturing, metal powder injection molding technology is changing the way we think about the production process. This technology can not only produce high-quality parts with complex shapes and fine features, but also mass production, reducing production costs. This paper will introduce the principle, advantages, application and future development trend of metal powder injection molding technology in detail.

1.The principle of metal powder injection molding

Metal powder injection molding is an advanced manufacturing technique that allows designers and engineers to fabricate complex metal parts in a very flexible manner. The basic process consists of four steps:

Powder preparation: Metal powder is mixed with adhesive to form a slurry that can be injected into shape.

Injection molding: The slurry is injected into the mold through a syringe and then cured at a certain temperature and pressure.

Demoulding: Removing the cured part from the mold.

Post-treatment: By heating and degreasing treatment, residues in the parts, such as adhesives, are removed to improve strength.

2. The advantages of metal powder injection molding

High flexibility: Metal powder injection molding can produce parts with complex shapes, which gives designers the freedom to use their imagination to design more efficient parts.

High precision: Metal powder injection molding technology can achieve high precision manufacturing, and the error range can be controlled within a few microns.

Mass production: Metal powder injection molding technology is highly automated and can be continuously mass produced, greatly reducing production costs.

High material utilization: Compared with traditional cutting processing, metal powder injection molding technology can reduce material waste and improve material utilization.
