At Daihen America Inc., we shape the future of manufacturing with secure, scalable, and sustainable solutions. Our U.S.-based team is large enough to handle complex automation projects while staying close enough to deliver practical, dependable results.

Our work ethic, practical knowledge, and commitment to doing the right things are evident in every project. We take pride in delivering high-performing robotic welding systems that reflect our standards for quality, reliability, and long-term value.

Our Values

A shared philosophy that guides how we build, partner, and support our customers.

Our foundation

In 1985, the parent company name was changed to DAIHEN Corporation, and at the same time, the company established the corporate philosophy of “reliability and creativity”. Recently, DAIHEN Corporation name changed to DAIHEN America Inc. and we still follow this philosophy.

Our core values remain the same, which is a commitment to high quality service and delivering dependable, well-engineered solutions that customers can trust over the long term.

Reliability

We design systems that perform consistently, withstand demanding production cycles, and support long-term uptime.

Creativity

We apply practical innovation to solve complex manufacturing challenges, improve workflows, and help customers achieve better outcomes.

Quality service

We back every system with responsive support, training, and service so customers can operate with confidence.

Why manufacturers rely on us

We unlock new possibilities for our people. Every system is built to deliver measurable outcomes: consistent quality and improved productivity levels.

Our foundation

We have more than 100 years of welding experience to support your product automation needs.

We combine simulation-led design, deep welding skills, custom automation, and final-mile delivery to help manufacturers move from concept to qualified production faster.

1. Simulation-led design

No wild guesses. Using the latest technology tools, we verify reach, access, cycle time, and digital part fit while building the product design. This is core to our methodology for superior product building and automation.

2. Deep welding skills

Our proficient team consists of process experts, highly certified weld engineers who understand materials, fixturing, and what actual production demands are.

3. Custom automation from scratch

We begin with ready-to-use engineered cells and components, followed by customizing each and every product detail. From important tooling to HMIs, to fit your parts, workflow, and team. All this fastens up product deployment while making sure system is ideal for your operation.

4. Final-mile delivery

We bring people, process, and technology together and stay engaged throughout the entire build journey until your automation system produces well-qualified parts—not just until the power stays on.
