We would like to introduce examples where benefits arise from Metal Injection Molding (MIM). MIM, which shapes complex geometries using molds similar to plastic injection molding, can produce parts that are closer to the final shape. By reducing the number of machining areas and minimizing them, it can lead to cost reductions. Additionally, by combining parts and transforming them into complex shapes through MIM, it is possible to create shapes that leverage the cost-saving advantages of the MIM process, while also eliminating processes such as welding and assembly. 【Examples of Benefits】 ■ Horizontal hole shapes and undercut shapes - Shaping complex geometries using molds like plastic injection molding - Can be produced in shapes close to the final form (near-net shape) - Reducing machining areas allows for cost reductions ■ Integration of parts - Combining parts to transform them into complex shapes for MIM - Can create shapes that lead to cost reductions utilizing the MIM process - Eliminating processes such as welding and assembly can also contribute to cost reduction *For more details, please refer to the PDF document or feel free to contact us.

MIM, which is manufactured by pouring raw materials into a mold all at once, allows for shapes that are close to the final form during the molding stage, providing cost advantages. Shapes that previously required multiple processing steps can now be delivered with high precision in a single molding using MIM. Our company has the strength of being able to respond quickly because we manufacture our molds in-house. (We have published examples of shapes in the downloadable materials.)

MIM is a type of powder metallurgy method that uses metal powder as raw material, and it is a technology that enables the manufacturing of complex-shaped metal parts through injection molding. Since it uses molds for shaping, it is suitable for mass production. Additionally, it can handle difficult-to-machine materials such as stainless steel, leading to cost reductions due to reduced machining. 【Features】 ■ Complex three-dimensional shapes Using the same molding method as plastic injection molding, it can create complex shapes, allowing for near-net-shape forms that are close to the final product in a single molding process, which contributes to cost reduction. ■ High precision and high strength Dimensional accuracy can be achieved within ±0.5%, and surface roughness can be below Ra3.2, ensuring high precision. A relative density of over 95% provides strength comparable to that of soluble materials. ■ Mass production Due to the use of molds in the manufacturing process, it is suitable for mass production, capable of handling hundreds of thousands of units per month.

"Powder metallurgy" is a method of manufacturing parts using metal powder as raw material, specifically referring to the pressing and molding process in a narrow sense. Flowable metal powder is poured into a mold, and a shaped body is produced through pressing. Since the forming time is very short, only a few seconds per piece, it allows for mass production. Additionally, powder metallurgy generally has a relative density of 70-90%, which means it contains pores internally. By controlling the sintering density, it is possible to create lightweight components. 【Features】 ■ Very short forming time of only a few seconds per piece ■ Capable of mass production ■ Provides high-quality stainless steel powder metallurgy parts ■ Capable of creating lightweight components by controlling sintering density *For more details, please refer to the PDF materials or feel free to contact us.

Here are the benefits of MIM (Metal Injection Molding). In "die casting," there are challenges such as insufficient strength and low heat resistance. By adopting MIM and changing the material to iron or SUS, both strength and heat resistance are improved. Additionally, in "lost wax," cost reduction is possible by omitting post-processing due to improved dimensional accuracy, while in "press processing," cost reduction is achieved through the reduction of integrated molding processes. **Benefits of MIM:** - **Die Casting** - Strength and heat resistance are improved by changing the material to iron or SUS. - Similar mold structures can be used, allowing for replacement even in complex-shaped parts. - **Machining** - Near-net shape reduces the number of processing areas, enabling cost reduction. - Capable of mass production, which may also lead to cost reduction. *For more details, please refer to the PDF document or feel free to contact us.*

MIM (Metal Injection Molding) is a type of powder metallurgy method that uses metal powder as raw material, allowing for the mass production of parts with complex three-dimensional shapes with high precision and strength. It is a composite technology of "plastic injection molding technology" and "powder metallurgy technology," making it possible to manufacture complex shapes that can be molded with plastic using metal. With a single molding process, a shape close to the final product (near-net shape) can be obtained, aiming for a reduction in machining. Additionally, through the application of insert technology, it can accommodate hollow and undercut shapes. Primarily using stainless steel, which is considered a difficult-to-machine material, we also handle materials such as superalloys.
