Advanced metal processing technology that creates the future.
A press die is a machine that is equipped with a die made for a press machine (a machine that moves up and down). Material is placed between the two halves of the die, and by operating the press machine to press from above and below, the product is created. Among press dies, there are different manufacturing methods for what are called single-stroke dies and progressive dies.
It is a specialized group based on a cooperative system!
When creating molds, which are essential for plastic molding, it is necessary to exercise the utmost care and foresight before production.

Design and manufacturing are possible with a minimum clearance of 0.003mm! Processing of new materials such as thin foil and high-strength fibers is also possible.
A consultation was received from an automotive parts manufacturer, stating that they were unable to punch out fiber materials with molds from other companies, resulting in poor productivity, and they wanted to process with our molds. In response, we proposed a minimal clearance of 0.003mm and improvements in mold structure and part accuracy. As a result, we were able to punch out the Vectran fiber material (t=0.05mm) due to the difference in clearance. 【Case Summary】 ■ Customer Industry: Automotive Parts Manufacturer ■ Consultation Content: Unable to punch out fiber materials with molds from other companies ■ Proposed Solution: Minimal clearance of 0.003mm ■ Technology Used: Improvements in mold structure and part accuracy *For more details, please refer to the PDF document or feel free to contact us.

Guaranteed with submicron order shape measurement! We will provide quality assurance in line with the improvement of precision processing technology.
We would like to introduce a case where a manufacturer of automotive parts solved their challenges by introducing a new machining center and wire electrical discharge machine. The manufacturer was struggling with the inability to produce high-precision products despite creating punches and dies through three-dimensional processing to accommodate the miniaturization and complex shapes of products. They faced issues not only with defects but also with the inability of conventional measuring instruments to adequately measure shapes, making it impossible to guarantee precision. To address this, they ensured shape measurement using a laser microscope, which could measure shapes that conventional contact-type tracers could not. 【Overview】 ■ Customer's Industry: Automotive parts manufacturing ■ Processing Technology: Parts processing with a precision of ±2μm using a new machining center and wire electrical discharge machine ■ Quality Assurance: Implementation of three-dimensional measuring instruments (from Mitutoyo, OGP, TESA) and a laser microscope (from KEYENCE) to guarantee shape measurement in the sub-micron order. *For more details, please refer to the PDF document or feel free to contact us.
In the mold shop column, we will be sharing various information about molds from time to time! (We also publish the mold shop column on our Instagram.)
In the previous column, we introduced that there are mainly three types of press molds, focusing on the single-stroke mold. In this column, we will introduce the progressive mold! A progressive mold refers to a type that incorporates multiple processing methods, such as punching, bending, and drawing, into a single mold. This processing method sends the material to the next stage with each press, shaping the product. The material used is typically in a rolled form (coil material) and is automatically fed to the next stage. The advantages include improved production efficiency and stable quality due to automation, as well as the ability to perform more complex processing compared to single-stroke molds since multiple processes can be incorporated. On the other hand, the disadvantages include the complexity of the mold design and manufacturing compared to single-stroke molds, which makes the production cost of the mold relatively high. Additionally, there is a possibility of a "boat bottom phenomenon," where a shift occurs at the tip of the product. (We plan to cover the "boat bottom phenomenon" and "shift" in a future column!) Products suitable for progressive molds are those that require mass production or complex processing. In the next column, we will explain the "transfer mold"!
In the mold shop column, we will continuously share various topics about molds! (We also publish the mold shop column on our company Instagram.)
In this column, I will introduce the "boat bottom phenomenon"! When you want to punch out terminal shapes like those in the icon diagram, processing them at every pitch, as shown in Figure A, results in a reduced area for holding during the punching process. This can lead to situations where the punch comes down with such force that the stripper plate cannot hold the product securely, causing it to tilt over. This is known as the boat bottom phenomenon. The tilted product resembles a boat bottom, hence the name. To avoid this, changes in layout are necessary. For example, one solution could be to use multiple pitch feeding as shown in Figure B. In the case of multiple pitch feeding, a single group is punched out in one go (all punches come down simultaneously), leaving no room for the product to tip over, thus preventing such issues. However, on the other hand, this will narrow the spacing between the dies, which raises concerns about die strength. It is essential to determine specifications based on strength calculations.
I have summarized the basic content regarding the impact of clearance discrepancies due to board thickness differences and the reduction of running costs achieved through uniform clearance.
Clearance (CL) refers to the gap between the punch and die of a mold. CL is set at 4-7% of the material thickness. The range of 4-7% is determined by the thickness of the material. In the PDF document, we introduce: - Examples of clearance settings by material thickness: t=0.1mm / t=0.05mm / t=2.0mm - The impact of uneven clearance based on material thickness - The benefits of achieving uniform clearance Table of contents: - What is clearance? - How to set clearance - Examples of clearance by material thickness - Benefits of achieving uniform clearance
【Kyushu Mechanical Components Technology Exhibition Participation】What causes burrs to occur? We will also introduce measures against burrs!
Burrs that inevitably occur when using press molds. Is there a way to reduce burrs? Why do burrs occur in the first place...? Many people may have such questions about whether it is possible to create molds that produce no burrs at all. If burrs can be minimized, there are many benefits, such as reducing the time for burr removal and ensuring product accuracy. In this document, we will explain in detail why burrs occur in press molds and what measures can be taken to minimize them. Nagumo Manufacturing will be exhibiting at the Kyushu Machine Element Technology Exhibition in Fukuoka, which will be held from November 29 (Wednesday). We look forward to your visit. *For details about the exhibition, please refer to the basic information!
