This time, we will focus on stamping processes and explain a simple method for selecting materials suitable for stamping for designers.

Rational material selection enables the design of products that are easy to manufacture, leading to reduced costs due to fewer processes, improved productivity during mass production, and enhanced reliability and durability of the products. Designs with high forming difficulty will increase material and processing costs. Indicators of material properties for evaluating materials suitable for stamping include tensile strength, yield strength, elongation, hardness, Erichsen value, limiting drawing ratio, and conical cup value. However, two specific characteristic values that can directly evaluate formability are as follows: 1. The n-value representing work hardening characteristics 2. The r-value (Rankford value) representing anisotropy The n-value and r-value are characteristic values that directly relate to the quality of actual stamping processes, and this evaluation allows for the selection of appropriate materials. *For more details, please download the PDF or contact us.*

This document explains the key points of material selection.

In the process of spring design, once the stress level of the required material is determined, it is necessary to select a material that possesses those characteristics, and an understanding of the properties of the material is crucial.

This is a collection of examples of drawing processes manufactured with progressive drawing dies using automatic press processing! Shall we solve your problems with drawing processes together?

A drawing die refers to a type of mold used in a processing method that creates various shapes of bottomed containers, such as cylinders, rectangular tubes, and cones, from a single thin sheet of metal. A characteristic feature of the formed products is that they have no seams. It is said to be the highest level of press processing. We would like to introduce a case study using our progressive die that has actually solved customer problems! Our products are primarily made using automatic press processing, ensuring stable quality, cost performance, and short delivery times, allowing us to meet customer demands. Please feel free to download it.

<Title> Development of Gene Expression Control Technology through RNA Hacking In the latest presentation paper, we have utilized Abby. Associate Professor Yosuke Katsuta from Kumamoto University Graduate School of Advanced Science and Technology, Analytical Chemistry Laboratory (also co-founder of StapleBio), will be giving a presentation in an online seminar. He is working on the development of RNA hacking technology aimed at controlling gene expression by utilizing short nucleic acids named Staple to change the higher-order structure of target mRNA. He will present the latest data focusing on the results of cell experiments and animal experiments in the development of this technology.
