MD Metalline is amongst the best companies that offer high precision Net Shape Metal Injection Molded Components to Original Equipment Manufacturers (OEMs) and other industries that need complex components, with consistent dimensions and manufacturing quality. Our Metal Injection Molding (MIM) process allows the production of complicated parts with precise tolerance and good repeatability with minimal machining and wastage of materials.
We manufacture our customized net shape MIM components based on customer drawings, CAD drawings, samples, and application needs. The manufacturing process involved precision tooling, feedstock manufacturing, injection molding, debinding, and sintering with control.
Net shape metal injection molding is suitable for the manufacturing of complicated parts having thin walls, intricate features, small holes, undercuts, and intricate profiles.
MD Metalline is an organization that strives at offering consistency and application specific MIM parts. This is done through effective manufacturing processes and quality control measures. We cooperate with our OEM customers throughout the whole process of designing, tooling and mass production of MIM parts.
Precision Net Shape Metal Injection Molding
Net shape metal injection molding is an approach that aims to manufacture parts as close as possible to their eventual desired shape.
In this technique, fine metal particles are combined with a binding system to produce a material that can be injection molded. This material is then injection molded in a carefully designed mold, debound, and finally sintered. At this stage, the metal part produced may need minimal or even no further processing depending on specifications.
Suitability for use of this net shape method is dependent on part geometry, material, tolerances needed, production quantity, among other factors.
What Are Net Shape Metal Injection Molded Components?
Net shape metal injection molded components are metal parts that have been formed through the MIM process with the aim of producing the desired geometry through molding and then sintering.
Whereas material removal processes involve working on a large metal piece to get the desired geometry of the part, MIM forms the fundamental geometry of the component by molding.
This is especially advantageous where:
- Complex three-dimensional geometries
- Small and intricate features
- Thin sections
- Internal features
- Repeated production requirements
- Multiple integrated design features
Net shape manufacturing can help simplify component production when the geometry is suitable for the MIM process.
Net Shape MIM Manufacturing Process
Metal Powder and Binder Preparation
Suitable metal powders are combined with a binder system to create a feedstock with the required molding characteristics.
Material selection depends on the component’s mechanical requirements, operating environment, geometry, and application.
Precision Tooling
A precision mold is designed according to the required component geometry. Tooling design takes into consideration feedstock flow, component geometry, ejection, shrinkage, and sintering behavior.
Injection Molding
The prepared feedstock is injected into the mold cavity under controlled conditions. This produces a molded component that reproduces the geometry of the tool.
Debinding
The binder is removed from the molded component using a controlled debinding process.
At this stage, the component must be handled carefully before sintering because it has not yet developed its final mechanical strength.
Sintering
The debound component is heated under controlled conditions. During sintering, the metal particles bond together and the component develops its final structure and properties.
Final Inspection
Finished components can be inspected for dimensional accuracy, material characteristics, surface condition, and other customer-specific requirements.
Advantages of Net Shape Metal Injection Molding
There are many potential manufacturing benefits of net shape MIM for components with suitable design.
Complex Part Geometry
Metal Injection Molding is capable of forming complex 3D parts, which could require more than one operation during their machining using traditional processes.
Lower Level of Secondary Machining
As a part is formed closer to its final geometry, the level of machining that will be necessary after MIM is going to be lower.
Repeatable Manufacturing
In case of adequate production volumes, MIM is capable of providing repeatable manufacturing of complex parts using controlled tools and process parameters.
Effective Material Use
Being formed closer to final geometry, MIM is capable of eliminating additional material removal when comparing it to subtractive manufacturing.
Integrated Features
Many features of the design can potentially be included in one molded part, thus eliminating the necessity of manufacturing and assembling several parts.
Scalable Manufacturing
If appropriate tooling is developed, injection molding can allow for repeatable production of large amounts of suitable parts.
Applications of Net Shape MIM Components
Net shape metal injection molded components can be used across a wide range of industrial applications.
Potential application areas include:
- Automotive components
- Medical and healthcare equipment
- Electronics
- Telecommunications
- Industrial machinery
- Precision mechanical assemblies
- Consumer products
- Power transmission equipment
- Hardware and mechanical systems
- Miniature precision components
The suitability of MIM depends on the component geometry, material, production quantity, tolerances, and functional requirements.
