【August 2020 NETISV Rank Upgrade!】 Highly active within the factory! Long-lasting domestically produced recycled plastic sheets that can be used for various purposes, such as ground protection!

It is necessary to always maintain a situation where problems do not occur within the factory. Of course, safety measures are important, but we also need to work on preventing ground deterioration and protecting products from damage, as they will naturally degrade over time. In such cases, the "Ripi Board" is helpful. The "Ripi Board" is a recycled plastic mat certified by the Ministry of Land, Infrastructure, Transport and Tourism's NETIS, Eco Mark, and ARIC, and it offers many benefits. [Features] ○ "Durable": Resistant to oil, mud, and water, capable of supporting 20-ton trucks. ○ "Lightweight": Can be easily installed without heavy machinery. ○ "Long-lasting": Utilizes "waste wire insulation material" that is highly resistant to environmental factors. It is strong against direct sunlight and has a proven track record of 30 years of use. ○ "Eco-friendly": Can be collected and recycled when no longer needed. ○ "Easy to clean": Pattern design makes it easy to remove mud stains. Please touch and check it out first! ☆Currently, we are giving away cut samples (one-sided raised type)☆ If you would like one, please fill out the inquiry form below, clearly stating "Request for cut sample," and include the intended use you are considering.

Seminar Overview As the labor shortage in manufacturing sites becomes more severe, the labor costs and time losses associated with the "transportation" of products and components, as well as "cleaning" within factories, have become critical management issues that cannot be overlooked. In this webinar, we will introduce the latest use cases of "Autonomous Mobile Robots (AMR)" and "Commercial Cleaning Robots" that achieve productivity improvements in manufacturing environments. We will specifically address questions such as "How are other companies operating these technologies?" and "What kind of cost reduction effects can be expected after implementation?" by providing concrete explanations of actual before-and-after scenarios and operational flows. Factory managers and members of production technology and DX promotion departments who want to advance automation and efficiency on-site are encouraged to participate! Recommended for: - Those who are unsure about where to start with automation, labor reduction, and DX in their factories. - Those who want to alleviate labor shortages on-site and focus resources on core operations to improve productivity. - Those who want to stay updated on the latest trends in the use of transportation robots (AMR) and cleaning robots.
