Contract manufacturer of parts for electron microscopes and vacuum equipment
Since our establishment in 1967, Daiwa has operated as a contract manufacturer supplying parts for precision equipment such as electron microscopes, semiconductor inspection equipment, mass spectrometers, and vacuum film deposition equipment.
We handle the machining of many core parts that affect equipment performance.
The role of these parts is to ensure that equipment is able to deliver its full performance after devices have been installed.
That is why we strive to manufacture parts taking how well they perform into consideration.

Introduction to our technology
Micro electrical discharge machining (micro-EDM)
Ultra-fine hole machining is normally difficult, but with our in-house ultra-fine discharge electrodes, it is now possible to perform hole machining w...
Utilizing special deburring technology, we are able to perform mirror surface finishing up to the inner surface of fine holes.
Utilizing special cleaning technology, we are able to remove nano-level contaminants.
We perform osmium deposition by plasma-enhanced chemical vapor deposition (PECVD) to form stable conductive thin film.
Electron source, X-ray source filament machining
We manufacture parts by leveraging technologies such as the winding of ultra-fine wire coils, tungsten probe polishing, precision assembly by spot wel...
Surface Treatment, Heat Treatment
We respond to customer requests for plating, heat treatment, and film formation after part machining.
We provide support for all kinds of precision inspection such as optical microscopy, measurement microscopy, and electron microscopy.
