Surface Treatment
Diverse Surface Treatment Techniques
for a Polished Finish
At MITSUWA, we utilize acids, alkaline solvents, and ultrasonic cleaning to perform surface cleaning and contaminant removal.
We also offer chemical dissolution of core wires and barrel processing for deburring and surface polishing.
Cleaning and Dissolution
Filaments and electrodes require surfaces free from contaminants. To remove dirt accumulated during processing, we use ultrasonic cleaning and various chemicals, such as acid and alkaline solvents. Additionally, core wires made from molybdenum and iron used in filament production are dissolved and removed through chemical treatment.
- Ultrasonic Cleaning
- Nitric acid and sulfuric acid to dissolve core wires.
Other Examples
We offer chemical surface treatments like internal structure transformation through heat treatment and various mechanical processes such as edge rounding and mirror finishing. We can also coat metal surfaces with different materials upon request.
