MIM(metal injection molding) is a mixed manufacturing technology that combines plastic injection molding and metallurgy flexibility of metal powder. It is mainly used in the volume production of custom, small, complex metal parts. MIM is an innovative technology that is applied in markets of medical, aerospace, electronics, automotive, etc. 2fprototypes is experienced in molding and maintain a good relationship with our suppliers. Welcome to contact us if you are looking for metal&plastic injection molding solution.

Why Need Metal Injection Molding?

 

High density and strength

Metal parts from MIM keep dense material from 96% to 98%, which ensures durability and strength. The density is strong enough for secondary processing of electroplating, heat treating, machining, etc.
 

Volume-consistency

Machining is highly cost-effective in low-volume production. Mold has obvious advantage in mass production. MIM produces mass metal parts in one mold to ensure repeatability and consistency. Parts by MIM little tolerance.
 

Complex product design

MIM is suitable for metal parts with complex shapes without additional processing and assembly. Metal powder material can consist and bond by injection molding. MIM is easier to achieve thin wall and produce durable parts.
 



 

How does Metal Injection Molding work?

 

Prepare the feedstock

The feedstock for MIM is powder mixes of metal powder and organic binder. The metal powder to organic binder ratio is about 60%:40%. Metal powder and binder are placed into the device for mixing. The organic binder melt and coats on the metal powder uniformly while heating in the device. The materials are cooled and then granulated into mixing pellets.
 

Injection molding

The process of metal injection molding in the injection molding machine is identical with plastic injection molding. The pellets heat and be injected into the mold. The finished parts are ejected after cooling.
 

Debinding

The binder can result in the size of intended finished parts. This step will remove the first stage binder. Depending on the type of binder, the removal can be catalytic, aqueous, or solvent-based. The removal can not destroy the shape of the finished parts.
 

Sintering

In the last step of sintering, the remaining binder is removed completely. The binder is evaporated under the heating temperature while the particles fuse better. The void space between the particles is eliminated to the intended size.
