Quality Assurance

At Fuji Denshi, we provide quality assurance through extensive measurement, data collection, and analysis based on our experience in prototype development, in-house hardening, and machine manufacturing.

Data Analysis

data Our data report includes hardness distribution, heat and temperature distribution, and structure photograph together with our analysis based on structural composition and heating simulation.

Measurement Devices

State-of-the-art devices inspected regularly to assure precision.

Metal Analyzer

Used especially for carbon content measurement and confirmation of hardening quality for each material.

Digital Microscope

Full-focus resolution produces clear structure photographs in a short time and allows measurement of graphite spheroidized ratio and grain size.

Residual Stress X-Ray Meter

Measures residual stress at areas such as crankshaft fillets and gear bottoms. Using the smallest and lightest model in the world, we can analyze large works of inner diameter up to 170mm.
