Everything You Should Know About Injection Molding

Metal injection molding is a manufacturing process that uses metal powders and Ceramic Powder Injection Molding to produce components. The process starts by heating polymer to a liquid state and adding metal powder. Later the mixture is then injected into a Mould Steel Material and it needs to be cooled and solidified – followed by debinding and sintering.

What Are the Benefits of Metal Injection Molding?

MIM has grown significantly since its inception in the late 1970s. Injection molding is widely used in various industries from medical device manufacturing to aerospace and automotive. Well, the process is particularly well-suited for producing small, intricate parts with tight tolerances – it components that requires high degree of strength and durability. 

The Benefits of Using Injection Moldings Are: 

• This process can produce parts with complex geometric and tight tolerance

• Efficient and cost-effective 

• This process helps to eliminate the need for secondary machine operations.

• MIM is capable of producing parts with high complexity and also capable of producing wide range of material properties.

Kurling, Calligraphy, Angular holes, Internal & External threads can be achieved in MIM tool itself.

What Are the Different Types of Materials Used in MIM Process? 

The metal used in Metal Injection Molding depends on the application and desired properties of the part. Typically, the common metals used in MIM include low-carbon steel, titanium, stainless steel, and nickel-based alloys.

Every metal have unique properties making it suitable for different applications. Stainless steel is the most common metal used in Metal Injection Molding. It is a low-cost material – that is easy to work and offers good strength and wears resistance.

Cobalt-chrome is highly wear resistant material – it is typically used in medical implants and other medical devices. Titanium is lightweight and corrosion resistant metal often used in aerospace components.

Wrapping Up 

To start with MIM Metal Injection Molding project, you should first identify the requirement of the material. Then you should start create a detailed design of the part, that includes all necessary features like ribs and undercuts. Once the design is completed you should choose the right material from injection molding shoulder.
