Mim Metal Injection Molding Process

Fine metal powder less than 20µ particle size is blended with thermoplastic and wax binders in precise amounts.

Mim metal injection molding process. The flow diagram in fig. This frees designers from the traditional constraints associated with trying to shape stainless steel nickel iron copper titanium and other metals. Metal injection molding mim is a metalworking process in which finely powdered metal is mixed with binder material to create a feedstock that is then shaped and solidified using injection molding the molding process allows high volume complex parts to be shaped in a single step. After molding the part undergoes conditioning operations to remove the binder debinding and densify the powders.

Metal injection molding is a metalworking process in which finely powdered metal is mixed with binder material to produce a feedstock which is then shaped by injection molding. After molding the part undergoes conditioning operations to remove the binder and densify the powder. Metal injection molding processes include state of the art metal injection molding equipment and a full compliment of secondary operations. These facilities together with the capbilities of the mim process enables jiangsu tech to manufacture highly detailed parts to close tolerances without significant machining near net shape.

Metal injection molding mim process is ideally suited to the type of product which demands complex light thin and small scale designs to be produced in large quantities to net shape. 2 shows the sequence of processing steps. The metal injection molding mim process starts with the compounding or feedstock preparation process. The metal injection moulding mim process mim merges two established technologies plastic injection moulding and powdered metallurgy.

The metal powder to binder ratio is approximately 60 40 by volume. The fine metal powders used combine with higher sintering temperatures to allow mim to achieve near full density in the final article. Metal injection molding mim merges two established technologies plastic injection molding and powdered metallurgy. In the 1970s this process was developed to allow the processing of metal powders by raymond wiech in the us widely considered the inventor of the metal injection molding process.

Mim products are not limited in shape complexity due to the flexibility of the injection molding process.
