What is Metal Injection Molding

Metal injection molding is a new type of powder metallurgy near-net forming technology that has been extended from the plastic injection molding industry.
In order to improve its performance, metal or ceramic powder can be added to the plastic to obtain products with high strength and good wear resistance. In recent years, this idea has evolved to maximize the content of solid particles and to completely remove the binder during the subsequent sintering process and densify the forming blank. This new powder metallurgy forming method is called metal injection molding.

First, the metal powder and the binder are selected according to the MIM requirements, and then the powder and the binder are mixed into a uniform feed at a certain temperature by a suitable method. After granulation, the molded product is subjected to degreasing After sintering the densification into the final product.
MIM products due to the complex shape, sintering shrinkage, most of the sintering is still completed after the sintering treatment, including shaping, heat treatment (carburizing, nitriding, carbon nitriding, etc.), surface treatment (grinding, Chemical plating, shot peening, etc.).

What 3D Printing Powder is Used for

Using 3D printing techniques, it is possible to create view molds in hours or days because of the rapid prototyping characteristics of 3D printing, car manufacturers can apply to the development of automotive shape plans.
Compared to the traditional handmade sludge mold, 3D printing can more accurately convert the 3D plan into something, and the time is shorter, improve the level of production efficiency of the car plan.

At present, many manufacturers have been in the planning aspects of the beginning of the application of 3D printing skills, such as BMW, running the middle of the plan. Car manufacturers can use 3D printing techniques to automate small batches of custom components and production, and are able to create and create complex shapes such as inorganic form factor, hollow and negative tension.
3D printing can quickly make the appearance of complex parts, when the test results, change the 3D file from the new print can be tested again.
