井上鉄工所 Product Lineup

At the "Saitama Business Arena 2025" exhibition, we showcased and presented original incense holders created in collaboration with various partner manufacturers, receiving much support and warm words from many attendees. We would like to reintroduce the YouTube video summarizing the production process of the incense holders that we presented at the exhibition. Our company is committed to responding flexibly to customer requests, even for projects that are challenging to handle solely with our own facilities. We collaborate with both industry peers and companies from different sectors to ensure a comprehensive one-stop system that covers everything from material procurement to processing, assembly, and delivery. In recent years, there has been a decline in companies capable of working with cast materials, leading to an increase in inquiries from customers seeking new partners or suppliers. As part of our overflow measures, if you have any challenges, please feel free to consult with us. *You can view the YouTube video via the related link or by scrolling down to the bottom of this page. *For more details, please download the PDF materials or feel free to contact us.
