CASTEM Company Overview

Castem Co., Ltd. will exhibit at the first domestic specialized exhibition for casting-related products and services, "Foundry Tech + Expo 2026," which will be held at Tokyo Big Sight from September 9 (Wednesday) to September 11 (Friday), 2026. We will provide proposals tailored to our customers' challenges from the perspective of "method conversion through three casting methods," addressing familiar issues in manufacturing such as reviewing component costs, improving design flexibility, and accommodating small lot procurement. At our booth, we will conduct casting demonstrations that have received positive feedback each time, as well as display works that have won the grand prize at international casting contests. You will be able to see the potential of casting technology through actual items. We hope to present content that will be of interest to a wide range of departments, including design, development, procurement, and production technology. If you have any concerns regarding components, please consult the "Component Inquiry" at the Castem booth.
