Notice of Exhibition Participation for the Virtual Industry Exchange Exhibition 2020

Kyowa Hearts works with various types of metals. Some metals can easily rust depending on how they are handled.

It is not uncommon for mild, stain-like substances that are difficult to classify as rust to occur. To prevent these defects from arising in our products, we proceed with our work while keeping in mind the characteristics that lead to rust. This document introduces the conditions and environments under which various metals rust. We have succinctly summarized the conditions and environments that induce rust in various metal materials. Through the accumulation of knowledge and experience, we are well-versed not only in press processing technology but also in metal materials. Our team consists of professionals in metal processing. Would you like to solve your metal processing concerns together with us? Please feel free to contact us! *For more details, please download the PDF or contact us.*

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.

I have compiled a collection of examples of leaf spring manufacturing from Kyowa Hearts as a reference!

"I was wondering where to order leaf springs." If that's the case, leave it to Kyowa Hearts! "But the materials from Kyowa Hearts are hard to read because they are filled with wall text!" Yes, I apologize for that. That's why we've added skilled editors to include a table of contents and summarize the text, making it incredibly easy to read. This time, since it's a collection of leaf spring examples, there are actually more photos than text, so you can read it quickly! Please leave your leaf springs to Kyowa Hearts! *For more details, please download the PDF or contact us.

[Speaker] Miho Ko Shimada, Partner Attorney, Mori Hamada & Matsumoto Law Firm, Foreign Law Joint Enterprise [Key Lecture Content] The movement towards the implementation of CCS, which is positioned as an essential technology for decarbonizing hard-to-abate industries, is gaining momentum in Japan. Among the "advanced CCS projects" selected for business commencement in the early 2030s, some pipeline projects have progressed to the exploratory drilling stage. For shipping transport projects, discussions are underway to create mechanisms for clustering CO2 sources and improving shipping transport efficiency. In this seminar, following the full enforcement of the CCS Business Act on May 22, we will organize the current state of the business environment related to CCS and examine the latest discussions at the Agency for Natural Resources and Energy and the Ministry of the Environment (based on information available at the time of the event) from a legal perspective as we consider the shape of CCS projects leading to Final Investment Decision (FID). [Lecture Items] 1. Current state of the business environment related to CCS 2. Overview of the CCS Business Act 3. Overview of the cost difference support system for CCS projects (pipelines) 4. Structural considerations through the CCS value chain 5. Q&A / Business card exchange
