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.

Amines are compounds that are difficult to handle in GC analysis because they tend to adsorb or decompose on injection liners and columns. On the other hand, nitrosamines, ethanolamines, methylamines, and aromatic amines are utilized in a wide range of fields such as pharmaceuticals, pesticides, resins, and CO₂ absorbents, leading to an increasing demand for analysis in many laboratories. In this webinar, we will explain GC columns suitable for the analysis of amines. Compounds that traditionally required derivatization or special techniques can sometimes be analyzed directly using dedicated amine columns. We will provide thorough insights into the know-how needed to elevate your use of amine columns to the level of "selecting, using, and mastering." <Recommended for the following individuals> Beginners: Clear explanations of the basics of amine columns and selection points. Intermediate to advanced users: In-depth exploration of optimization approaches for target analysis and injection liner selection. Would you like to explore the world of GC analysis that goes one step further? We will deliver "truly useful knowledge" and "techniques you can try immediately" condensed for practical use in the field. https://register.gotowebinar.com/register/907431794825894999
