What is Metal Injection Molding?
Metal Injection Molding (MIM) is a highly specialised process that combines the technologies of plastic injection molding and powder metallurgy to produce many of the intricately-shaped, highly accurate orthodontic parts made by MO
The MIM process consists of mixing fine metal powders with thermoplastic binders to form a feedstock which is injection molded. After this, thermoplastic "binders" are chemically or thermally extracted from the part so that the part can be sintered to high density. During the sintering process, the individual particles metallurgically bond together as material diffusion occurs to remove most of the porosity left by the removal of the binder. The sintering process shrinks the part, providing a net shape that can be used as-is or further worked to add additional features or improve tolerances. The result is a near full density, high strength metal component.
Benefits of the Metal Injection Molding Process:
MIM offers mechanical properties that exceed those available with plastic injection molded or die cast materials. Metal Injection Molding also provides a cost-effective, automated alternative to the labor-intensive investment casting process. With the ability to produce highly complex geometries, MIM is an effective alternative to complex machined components or intricate assemblies.
Metal Injection Molding is especially effective at producing small, complex components that require thin, uniform cross sections (up to .250 inch). Thicker sections are typically limited factors that include the high cost of the raw material, the difficulties involved in molding defect-free thick sections, and the ability to remove the binders effectively from the molded parts.
The economics of the MIM process favors higher annual part volumes, making it the perfect choice for orthodontic manufacturing. Although MIM can be a cost-effective solution for small, complex parts at lower volumes, the cost of molding tools discourages lower volume applications.
To ensure that the full benefits of the Metal Injection Molding process are best realized, MO considers the MIM manufacturing process during the initial design stage of the product.
The primary benefits of the MIM manufacturing process include:

Nickel Titanium Wire Drawing
We are one of the few orthodontic manufacturers who have an in-house wire drawing facility. Our modern wire drawing shop can draw all Nitinol and Stainless-steel wires in-house. Modern Orthodontics Nickel Titanium wire is the result of years of research and advancement in several key areas of the material science over the period of years.
Nickel Titanium is an alloy which is complex to process and form. Very slight variations in a multitude of factors during manufacturing can alter the clinical performance of NiTi wires. MO has worked hard to achieve consistent force, elasticity and memory of each wire. The manufacturing processes some invented, some developed and others refined by MO to make NiTi distinct from all other NiTi archwires used in orthodontics. Only the scientific testing of a NiTi wire can determine its actual working characteristics. Modern Orthodontics NiTi archwires undergo intense scientific testing during the manufacturing process. Every wire undergoes a 100% final inspection before packaging.
NiTi wire provide lower initial load forces and increased residual forces as full shape recovery progresses. Lower Loading Forces of Engagement result in easier wire deflection and delivery to bracket, less stress on bonds and increased patient comfort. Higher Residual Forces of Recovery gives full shape recovery, complete unraveling and archform development by staying active to the end.
