Comparison Between Metal Injection Molding Process and Other Molding Processes

Comparison Between Metal Injection Molding Process and Other Molding Processes

MIM metal injection molding is suitable for stainless steel, iron-based alloys, magnetic materials, tungsten alloys, cemented carbides, fine ceramics and other series. The prepared parts are widely used in aerospace industry, military industry, medical treatment, machinery industry, daily necessities and other fields. Then the comparison of MIM metal injection molding and other molding process characteristics, which one has more advantages.

1. Comparison between MIM metal injection molding and traditional powder metallurgy process

As a near-net-shape technology for manufacturing high-quality precision parts, the metal injection molding china process has incomparable advantages over conventional powder metallurgy methods. MIM can manufacture many parts with complex shape features: such as various external grooves, external threads, tapered external surfaces, cross through holes, blind holes, recesses and key pins, stiffener plates, surface knurling, etc., with Parts with the above characteristics are not available by conventional powder metallurgy methods.

2. Comparison between MIM metal injection molding and precision casting

Precision casting For metals or alloys with relatively low melting points, precision casting can also form parts with three-dimensional complex shapes. However, it is powerless for refractory metals and alloys, cemented carbides, cermets, ceramics, etc., which is determined by the essence of precision casting; in addition, for small-sized, thin-walled, and large-volume parts, it is very difficult to use precision casting. or not feasible. The emergence of the metal injection molding mim process flow has solved the difficult problem of precision casting to a certain extent.

3. MIM metal injection molding and machining comparison

Traditional machining methods have recently improved their processing capabilities by automation, and have made great progress in efficiency and accuracy, but the basic procedures are still inseparable from step-by-step processing (turning, planing, milling, grinding, drilling, polishing, etc. ) to complete the shape of the part.

Finally, the machining accuracy of the machining method is much better than other machining methods, but because the effective utilization of materials is low, and the completion of its shape is limited by equipment and tools, some parts cannot be machined. In contrast, mim china metal injection molding allows efficient use of materials with unlimited freedom of shape.

For the manufacture of precision parts with small and difficult shapes, the metal injection molding process has a lower cost and higher efficiency than mechanical processing, and is highly competitive. MIM technology makes up for the technical deficiencies of traditional processing methods or the shortcomings of inability to make them, and does not compete with traditional processing methods. MIM metal injection molding technology can play its part in the field of parts that cannot be produced by traditional processing methods.
