Products Description

Ceramic Injection Molding (CIM) is a near-net-shape manufacturing process that combines the efficiency and flexibility of plastic injection molding with the excellent properties of ceramic materials. This technology involves mixing fine ceramic powder with an organic binder to prepare a feedstock with good fluidity. This mixture is then heated to a plasticized state and injected into a mold cavity. After cooling and solidifying into a green body, the part undergoes debinding and sintering processes to obtain high-precision, high-performance ceramic components with complex structures.
