We provide complex-shaped metal parts primarily made of difficult-to-machine stainless steel.

We will propose manufacturing methods that lead to greater cost reduction.

Among the methods of metal manufacturing, MIM (Metal Injection Molding), which belongs to powder metallurgy using powder as raw material, and powder metallurgy (press molding method) can be selected based on the desired shape. 【MIM (Metal Injection Molding)】 ■ For those considering forming complex three-dimensional shapes ■ For those looking for higher precision parts ■ For those who want to achieve integration *Other improvement proposals are also available. 【Powder Metallurgy】 ■ For those who want to mass-produce two-dimensional shapes ■ For those looking to reduce the weight of parts *We offer products made from stainless steel. We can propose both manufacturing methods, ensuring the best parts supply for our customers.

It is precisely because we use molds that we can easily create complex and unique shapes.

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.)

• Other molds

Due to mold forming, it is possible to create various complex shapes in one go! This reduces processing and leads to cost reduction.

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.

Leave metal powder injection molding to us.

Our company is engaged in a new form of metal parts manufacturing technology called "Metal Powder Injection Molding," which integrates metal powder metallurgy technology with plastic injection molding technology. By mixing metal powder with a binder (such as plastic resin), we perform injection molding within a mold, followed by a debinding process to remove the binder, and then high-temperature sintering to produce high-density metal products. *We have published a manufacturing method using illustrations on our website. We leverage the extensive knowledge of metal materials from the Mitsui Metals Group and combine it with plastic injection molding technology to provide high-quality, low-cost MIM products. **Features of MIM:** - Capable of producing complex three-dimensional shapes and suitable for mass production - Achieves higher dimensional accuracy - High density, high strength, high hardness, and high corrosion resistance - Compatible with various materials and difficult-to-machine materials - Proposes labor-saving in subsequent processes and cost reduction, etc. *For more details, please download the PDF or contact us.

Due to its high density, it improves strength and airtightness! Introducing the benefits of MIM technology that also leads to cost reduction.

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.*

Relative density is over 95%, making it high density! The construction method can be smoothly replaced.

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. (A list of main materials is available in the catalog.) 【Features】 ■ Three-dimensional complex shapes ■ High precision ■ High strength ■ Mass production ■ Difficult-to-machine materials *For more details, please refer to the PDF document or feel free to contact us.
