Metal Injection Molding vs. CNC Machining
Metal Injection Molding Services
- Uses custom mold (requires additional lead time and cost)
- Expensive to redesign (requires the creation of new mold)
- Fastest part production
- Cheaper cost per part with high quantity runs
- Ideal for producing parts made from softer plastics
- Rubber and flexible materials can use this method
CNC Machining Services
- Uses CAD file for production
- Allows for cheaper design iteration
- Rapid part production (not as fast as injection molding)
- Cheaper for smaller quantity runs
- Best for harder plastics
- Larger variety of materials available
- Allows for tighter tolerance and surface finishing
Metal Injection Molding Services in US
Redstone Manufacturing provides advanced metal injection molding services for companies requiring high-volume production of small, complex, and high-strength metal components. Our engineering teams and ISO-certified MIM facilities deliver parts with exceptional detail, tight tolerances, and consistent repeatability. Designed for industries where precision and durability are essential, our metal injection molding MIM services support both prototype development and full-scale production.
The Metal Injection Molding Process
Metal injection molding combines the flexibility of plastic injection molding with the performance of metal materials. The MIM process begins with fine metal powders blended with a binder to create a feedstock. This feedstock is injected into a mold cavity to form the “green” part. After molding, the binder is removed through chemical or thermal debinding, and the component undergoes sintering, where it densifies to near-solid metal.
The result is a fully dense metal component with complex geometries that would be impossible or extremely costly to achieve through traditional machining or casting methods. Our metal injection molding services ensure consistent quality across high-volume production while maintaining precision and structural integrity.

FAQ's ABOUT OUR
METAL INJECTION MOLDING SERVICES
Yes. This process often creates intricate parts with high strength and wear resistance and has gained popularity over the past twenty years. Industries that now use metal injection molding (MIM) include electronics, consumer products, aerospace, firearms, and medical.
Metal injection molding offers manufacturers a variety of material options. It’s a cost-effective way to produce a high-volume of complex parts; it’s faster than investment casting, net-shape parts are created with minimal waste, and the process can yield parts with complex features. Parts manufactured are usually smaller; as parts get larger they also get more expensive to produce, and high material cost are all disadvantages of metal injection molding.
Both MIM and die casting involve injecting metal into a die, but this is where the similarities end. Die casting typically uses aluminum or zinc alloy while MIM uses steel alloys. MIM is more time-intensive and involves mixing metallic powder with a thermoplastic binder, which is added to a die and then undergoes various heat treatments to achieve the final product. With die casting, molten metal is pushed into metal dies, allowed to cool; then, the final part is removed.
First, finely powdered is mixed with a thermoplastic binder that is injected into a die. Once that material sets, it goes through a number of healing processes to remove the binder and further harden the part.
