 The biggest benefit of metal injection molding (MIM) at ASH INDUSTRIES is arguably its ability to achieve complex geometries and intricate details at high volumes, offering several advantages over traditional metalworking methods:

  • Cost-effective for intricate parts: MIM excels at producing complex shapes that would be expensive or even impossible to create through machining or other traditional methods. 

  • High-precision and tight tolerances: MIM delivers exceptional detail and dimensional accuracy, rivaling traditionally machined components.

  • Mass production capabilities: Unlike some metalworking techniques limited to small batches, MIM allows for high-volume production of identical metal parts.

Exceptional MIM parts come from smarter thinking.

the three phases of metal injection molding and overmolding at ash industries

Metal Injection Molding (MIM) is a manufacturing process where metal powder is mixed with a binder to create a moldable material. This material is then injected into a mold under high pressure to form the desired shape. Once formed, the binder is removed through a debinding process, and the metal particles are sintered together to create a strong, near-net-shape metal part. MIM is a cost-effective way to produce complex metal parts in high volume.

NET SHAPE?

MIM (Metal Injection Molding) is a process specifically designed to achieve net shape for metal parts as opposed to casting a metal part and then achieving ideal shapes by secondary operations. This means the parts produced through MIM require minimal to no post-processing for their final form.

Here's a breakdown:
Net Shape vs. Near-Net Shape: Net shape refers to a perfect final form achieved directly from the manufacturing process, while near-net shape allows for minimal additional work.


MIM's Advantage: MIM offers a significant advantage over traditional metalworking methods like machining. Machining involves carving away excess material from a solid block, leading to significant waste and requiring precise calculations to achieve the desired shape. MIM, on the other hand, builds the part layer-by-layer using a mold, minimizing material waste and achieving intricate details close to the final form.


Slight Shrinkage: It's important to note that MIM parts do experience between 15% and 30% shrinkage during the sintering process, when the binding material is removed and the metal powder particles are fused together in a 98% dense, no porosity, homogenous component. The shrinkage in a MIM part is predictable according to the content of the original material and accounted for during the mold design stage to ensure the final parts meet the desired dimensions.

People also ask:

  • Metal injection molding (MIM) is a metalworking process in which finely-powdered metal is mixed with binder material to create a moldable "feedstock." This feedstock resembles plastic used in injection molding. The metal-infused feedstock is then injected under high pressure into a precisely designed mold cavity, similar to how plastic is shaped in injection molding. Once formed, the binder is removed through a debinding process, leaving behind a near-net-shape metal part. Finally, the part undergoes a high-temperature sintering process, transforming the metal powder into a solid and robust metal component.

  • The SUPERMOLD program utilizes specialized inserts to existing molds so we simply machine a small area to make your sample parts in that time frame. The lifetime tooling is then ready for full production runs very quickly.

  • MIM can produce small parts with complex features, whereas die casting is better suited to larger parts. MIM excels at intricate shapes due to its injection molding nature, while casting is better for simpler, larger parts. Additionally, MIM allows for wider material options, including ferrous metals, compared to casting's usual focus on non-ferrous metals.

  • CNC machining and injection molding metal (MIM) take opposite approaches. CNC carves away metal for precise, one-off parts, while MIM builds intricate shapes in high volumes using metal powder and a mold. Though both handle various metals, MIM often favors steel due to the sintering process

  • SUPERMOLDS have a lifetime warranty, but even normal injection molds are carefully maintained by ASH's in-house tool-making facility. Typical lastic injection molds last from hundreds of thousands to over a million cycles but here, a plastic injection mold lifespan is extended to the extreme thanks to our maintenance, structure, SPI classification and materials.

  • Generally, MIM tends to be more cost-effective than CNC Machining for large production volumes due to economies of scale and faster production rates. The initial high cost of mold creation in Metal Injection Molding is offset by the lower per-unit cost in high-volume production.

  • Piece-part price for injection molding is going to be significantly lower compared to 3D printing once you reach a high volume of parts. ASH actually brings that minimum down thanks to the SUPERMOLD PROGRAM where you can get less than 1000 parts for less than the cost of 3D printing.

  • The biggest differences are porosity, strength, cost and energy expenditure. The additional polymers and steps in the MIM process add to the expense of production, and it takes more energy to produce the pieces. Powder metallurgy is less expensive generally and takes less energy, but also produces parts that are not as strong.
