Mim Metal Injection Molding Process

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 metal injection molding process.

After molding the part undergoes conditioning operations to remove the binder and densify the powder. 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. The fine metal powders used combine with higher sintering temperatures to allow mim to achieve near full density in the final article. The complex parts just need to be shaped in one step during the whole process.

The flow diagram in fig. 2 shows the sequence of processing steps. Metal injection molding mim merges two established technologies plastic injection molding and powdered metallurgy. 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.

Mim products are not limited in shape complexity due to the flexibility of the injection molding process. 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. The metal powder to binder ratio is approximately 60 40 by volume. After molding the part undergoes conditioning operations to remove the binder debinding and densify the powders.

The metal injection molding mim process starts with the compounding or feedstock preparation process. Finemim provides innovative technical solutions to reduce product cost improve product quality and improve process efficiency by using of ingenuity. This frees designers from the traditional constraints associated with trying to shape stainless steel nickel iron copper titanium and other metals. Metal injection molding processes include state of the art metal injection molding equipment and a full compliment of secondary operations.
