In-Depth Review TG4G Review ·2026-06-26 · For reference only

Basic Site Positioning

This is the official website of Matsumoto Seimitsu Co., Ltd., a precision manufacturing enterprise based in Nagano Prefecture, Japan. Its core businesses include wind tunnel test model manufacturing, precision electrical discharge machining, and the processing of supporting jigs, tools and industrial components for the aerospace sector. It is a professional processing enterprise with nearly 60 years of industry history.

Core Business & Features

The company's core advantage lies in high-precision processing: it specializes in wire-cut electrical discharge machining and sinker electrical discharge machining. It can process high-hardness materials and complex structural components that cannot be handled by ordinary cutting processing. This type of processing is usually the final step in product manufacturing, which carries high risk, but the company has accumulated extensive experience in the field. At the same time, it has deep roots in the aerospace industry for decades, and can complete the full process of aerospace test model manufacturing from design and assembly to manual adjustment. It also supports combined processing integrated with 3D printing. Its core clients include top industry players such as Mitsubishi Heavy Industries and the Japan Aerospace Exploration Agency (JAXA), and it enjoys extremely high recognition in the industry.

Pros, Cons & Applicable Scenarios

Pros: Solid technical accumulation, rich experience in high-difficulty processing, strict precision and quality control.
Cons: The official website only serves as a corporate display platform, with no online interaction channels, no public pricing or service details, and no Chinese language support, which is unfriendly to non-Japanese clients.
This website is only suitable for corporate clients with demand for aerospace precision processing and high-end electrical discharge machining who are looking to connect with Japanese processing manufacturers.

Accessibility from China

The website can be accessed directly from China's internet, no proxy is required.
