井上鉄工所 List of Products and Services

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.
