ContactFrom design to assembly and inspection — delivered through a fully integrated production system.
From design and material procurement to molding and printing—and from assembly to quality assurance and environmental testing—our one-stop system enables rapid optimization of your QCDS (Quality, Cost, Delivery, and Service).
Business Overview BUSINESS
Printing x molding x assembly.
A One-Stop Manufacturing Solution
TDI’s integrated production system combines advanced screen printing design technology with circuit pattern printing, resin molding, and assembly.
From design to assembly and inspection, we deliver a seamless, end-to-end solution through our in-house capabilities and collaborative network. We flexibly support not only unit-level production but also individual components and prototype development.
This integrated approach ensures high functionality and consistent product quality.We are committed to solving critical challenges in high-reliability applications—supporting everything from high-mix, low-volume production to long-term stable supply.

REASON Why we’re chosen
Over 70 Years of Expertise Built Through Continuous Challenges
Our strength lies in our ability to provide one-stop support from design to assembly and inspection, leveraging “live data” accumulated through decades of experience.
Since our founding in 1956, we have built extensive on-site expertise across a wide range of industries requiring high reliability, including railways, construction machinery, automotive, medical devices, low-voltage systems, and aerospace.
Unit Delivery that Solves Labor Shortages and Reduces Man-Hours and Costs
Traditionally, customers procured individual components and carried out assembly and inspection on-site. By entrusting TDI with a comprehensive solution—from design to assembly and inspection—everything can be completed through a single supplier under one part number.
This approach streamlines logistics and reduces on-site assembly time, helping to address labor shortages while optimizing overall costs.
A Fast and Flexible Support System through Domestic and Global Collaboration
With sales offices in Tokyo, Osaka, Nagoya, Shizuoka, Hamamatsu, and Fukuoka, we provide prompt, face-to-face support during the development phase. In mass production, our wholly owned subsidiaries in Sagamihara and Vietnam operate with standardized equipment and processes, enabling mutual backup. This establishes a robust BCP system that ensures uninterrupted supply even in the event of disasters or equipment issues. By combining close communication in Japan with strategically located overseas production, we help our customers achieve shorter lead times while maintaining strong cost competitiveness.
PRODUCTS
A Wide Range of Products and Flexible Responsiveness
We offer a comprehensive range of products, from design sheets to fully assembled units, including membrane switches, touch sensors, pressure-sensitive sensors, resin housings, metal nameplates, and weather-resistant labels for outdoor use.
