[Proposal for Use] Proposal to a certain automobile parts manufacturer

[Proposal for Use] Proposal to a certain automobile parts manufacturer

Improving the yield of automotive parts by 50%! Introducing case studies for automotive manufacturers.

Namitai's parts and components are active in various fields, from global products to everyday items. The required shapes, strengths, and precisions vary greatly. Based on a unique design philosophy from irregular wire, we respond to diverse needs. For a certain automotive parts manufacturer, when producing parts from expensive materials, the challenge was that conventional punching from standard sheet materials resulted in about 80% material loss. [Customer's Challenges and Issues] ■ Improving yield of high-grade steel parts ■ Conventional methods → When producing parts like the one shown from expensive materials, conventional punching from standard sheet materials results in about 80% material loss... <Example case using high-grade steel> - Ring component: Thickness 3mm × Diameter 280mm - Sheet material: Thickness 3mm × 300mm × 300mm - Material mass: 1.2kg (specific gravity 7.9) - Material loss = 1.0kg *For more details, please refer to the PDF document or feel free to contact us.

Parts | How to make complex parts from irregular coils

Parts | How to make complex parts from irregular coils

We propose specifications according to the purpose and function! Introducing the benefits of irregular forging, such as omitting the press process and labor-saving.

"Shape forging" offers cost advantages by approximating the final shape of parts at the material stage, allowing for the omission and simplification of cutting and forging processes, as well as improving yield. Additionally, compared to other methods, it enhances strength by utilizing toughness and improves quality in terms of precision and surface characteristics. While there are constraints on the freedom of shape due to processing characteristics, we will propose specifications according to the application and function. [Advantages of Shape Forging] ■ Omission and labor-saving of the pressing process ■ Improved yield ■ Increased strength *For more details, please refer to the PDF materials or feel free to contact us.

Processing Technology | Unique Precision Cutting Technology

Processing Technology | Unique Precision Cutting Technology

Fine cut | A cutting method that minimizes burrs, allowing for process simplification and serving as an alternative to sintering and pressing.

Our unique shear technology allows for the continuous and high-precision cutting of irregular coils. The proprietary method "Fine Cut" offers excellent flatness of the cut surface, with minimal occurrence of burrs and deformation, enabling some cases to be used directly as components. 【Capabilities of Fine Cut】 ◆ Process Simplification Due to the excellent flatness of the cut surface, it is possible to omit or reduce subsequent processing (such as barreling and machining). ◆ Continuous Production High mass production capability is achieved by continuously cutting from coils. ◆ Dimensional Accuracy - Minimal deformation leads to high length accuracy. - High length accuracy ensures stable weight per piece. *Examples of use: Slag, weights, etc. ◆ Method Switching Enables the switching of sintered parts, pressed parts, and former parts to Fine Cut. *Sintered alternative parts, pressed alternative parts. ◆ Environmental Consideration By achieving simplification and labor-saving through process omission, continuous production, and method switching, we can engage in environmentally friendly manufacturing.

Cold Forging Technology

Cold Forging Technology

Proposal for cost reduction through cold forging [up to 50 percent]

In "Cold Forging Technology," wire is cut within the machine, and pressure is applied to the metal using molds, deforming it by drawing or expanding to automatically process it into the desired shape. Since there is no cutting process, there are no chips produced, and material loss is minimal. Because it is processed using molds, the machining accuracy is high, and there is little variation in quality. Cold forging combined with unique processing technology can accommodate complex shapes. We offer VA (Value Analysis) and VE (Value Engineering) proposals. 【Features】 ■ Consistent process management from design to manufacturing ■ Integrated processing possible with cold forging ■ Increased efficiency through process reduction ■ Shaping done solely through forging without cutting *For more details, please refer to the catalog. Feel free to contact us with any inquiries.

[Proposal Example] Cost Reduction through Cold Forging Method from Cutting Processing

[Proposal Example] Cost Reduction through Cold Forging Method from Cutting Processing

From cutting processing to cold forging method! A cost reduction of 15 yen per unit is possible.

Here is a case where we proposed cost reduction and increased strength when we received a customer's order. By changing the processing method, we achieved not only a significant cost reduction in manufacturing expenses but also advantages such as "stabilization of metal flow and increased strength through plastic molding" and "mitigation of rising material costs for stainless steel and brass." As a result of this proposal, we were able to reduce costs by 15 yen per unit. At our company, we listen to our customers' requests, consider various manufacturing methods, and propose products that satisfy our customers by solving their fastening problems. 【Comparison (Machining / Cold Forging)】 ■ Lot: 5,000 units / 10,000 units ■ Unit price: 40 yen / 20 yen ■ Mold cost: - / 50,000 yen ■ Material: C3604 / S2700W ■ When producing 10,000 units: 10,000×40=￥400,000- / 10,000×20+50,000=￥250,000- *For more details, please refer to the PDF document or feel free to contact us.

[Proposal Example] Reducing Manufacturing Costs by Combining Cold Forging and Press Processing

[Proposal Example] Reducing Manufacturing Costs by Combining Cold Forging and Press Processing

Stable quality! We propose methods to enhance precision while also reducing costs.

We will introduce a case where we reduced manufacturing costs by combining cold forging and press processing. Since we were only using press processing, there was a lot of variation, and we received inquiries from customers about how to produce products with stable precision at a lower cost. In response, we proposed a combination of cold forging and press processing. This not only achieves stable quality but also opens up possibilities for new processing methods. At our company, we listen to our customers' needs, consider various manufacturing methods, and propose products that satisfy them by solving their fastening-related challenges. **Advantages of Combining Processing Methods** - Stability in quality can be achieved by combining with cold forging. - The stabilization of quality may lead to the possibility of new processing methods. *For more details, please refer to the PDF document or feel free to contact us.*
