Technology introduction Surface treatment (barrel polishing, heat treatment, chemical polishing, acid cleaning)
Barrel polishing, heat treatment, chemical polishing, acid cleaning
After press processing, the products undergo a combination of processes such as barrel polishing, heat treatment, chemical polishing, and acid cleaning.
This makes it possible to adjust hardness, improve appearance quality, and ensure cleanliness.
By selecting the optimum processing conditions according to the material properties and usage environment, we are able to provide highly reliable parts that meet the required specifications.
Barrel Polishing
- Message
- ・The product and abrasive stones (media) are placed in a barrel-shaped tank and rotated. - Polishes the surface by relative friction.
- the purpose
- Deburring, smooth finishing, descaling, R finishing, gloss finishing, surface hardening, etc.
Heat treatment
- Message
- - Hardening or softening of the metal structure can be achieved by adjusting the processing temperature and cooling method. ・We have continuous and batch type equipment.
- the purpose
- Remove residual stress after press working.
chemical polishing
- Message
- - The product is immersed in chemicals and the metal surface is chemically polished. - Removes minute irregularities and burrs uniformly without cutting.
- the purpose
- -Improved surface roughness and gloss. ・Products with complex shapes can also be processed.
Acid cleaning (passivation treatment)
- Message
- It is possible to consistently perform acid cleaning and passivation treatment of products.
- the purpose
- Effectively removes scale and impurities from the metal surface and forms a chemically stable oxide film.
