Mim Metal Injection Molding Process

This frees designers from the traditional constraints associated with trying to shape stainless steel nickel iron copper titanium and other metals.

Mim metal injection molding process.

Metal injection molding mim merges two established technologies plastic injection molding and powdered metallurgy. The metal powder to binder ratio is approximately 60 40 by volume. 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. Metal injection molding processes include state of the art metal injection molding equipment and a full compliment of secondary operations.

2 shows the sequence of processing steps. After molding the part undergoes conditioning operations to remove the binder debinding and densify the powders. After molding the part undergoes conditioning operations to remove the binder and densify the powder. Fine metal powder less than 20µ particle size is blended with thermoplastic and wax binders in precise amounts.

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. This frees designers from the traditional constraints associated with trying to shape stainless steel nickel iron copper titanium and other metals. Finemim provides innovative technical solutions to reduce product cost improve product quality and improve process efficiency by using of ingenuity. The fine metal powders used combine with higher sintering temperatures to allow mim to achieve near full density in the final article.

Mim products are not limited in shape complexity due to the flexibility of the injection molding process. The flow diagram in fig. 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. The complex parts just need to be shaped in one step during the whole process.
