Achieve lower costs than cutting processes! The production of three-dimensional products using PEEK (polyether ether ketone) is realized with a 3D printer!

In the production of three-dimensional products using PEEK (polyether ether ketone), injection molding is mainstream for large lots, while machining is the norm for small lots. For three-dimensional products made of PEEK, we have started contract processing using FDM (Fused Deposition Modeling) 3D printers with PEEK filaments produced by our company. This significantly reduces waste and allows for cost reduction. Additionally, with 3D printing, it is possible to create hollow or honeycomb structures internally, enabling material cost reduction and weight savings compared to machining, which can only produce solid forms. 【Features】 ■ Weight reduction: It is possible to achieve weight savings by creating hollow or honeycomb structures! ■ Cost-effectiveness: There is no material waste from machining, making it economically advantageous! ■ Precision: Production is possible at the intermediate level of JISB0405! (Consultation required) ■ Advancement: Due to the FDM method, it is possible to create shapes that cannot be accommodated by machining! *Please inquire as there may be limitations based on the shape. *If we are unable to produce after receiving an order, we will not charge for the costs incurred.

When conducting structural analysis of organic compounds, IR, NMR, and MS can be considered the three sacred treasures. If the analysis is performed correctly, it is possible to elucidate the structure of even quite complex compounds. However, actual spectra are often not of a single compound, as seen in textbooks, which can lead to significant challenges in interpreting results for beginners in analysis. Additionally, while database searches are a useful tool in structural analysis, the ability to read spectra is necessary to select the correct structure from among the candidates, not just pattern matching. In this course, we will lecture on the basic ways to interpret IR, NMR, and MS spectra, including simple explanations of principles, points to be aware of during analysis, and how to proceed with actual analysis, incorporating some exercises as well.

[Speaker] Yuri Ishii, Deputy Director, Environmental Economics Division, Minister's Secretariat, Ministry of the Environment [Key Lecture Content] This guide has been created with the intention of assisting companies in responding to the increasing demands for disclosure in various environmental fields, such as climate change and natural capital, and was published in June of the 7th year of Reiwa. The "integrated approach" introduced in this guide suggests that companies should not respond individually to the disclosure requirements in each environmental field, but rather engage with an awareness of their interconnections. Through this initiative, we aim to improve business processes under management involvement, effectively and efficiently address various environmental issues, and facilitate disclosure. The key points of the guide will be explained. [Lecture Items] 1. Expansion of environmental issues to be addressed 2. Significance of integrated initiatives and disclosure 3. Trends in sustainability-related information disclosure 4. Methods and benefits of integrated initiatives and disclosure; case studies of companies 5. Utilization of environmental due diligence for information disclosure 6. Q&A / Business card exchange
