What is mirror blast polishing?
Mirror spray polishing requires the use of a mirror sandblasting machine. The principle is to directly spray special elastic abrasives with extremely small particles onto the workpiece surface for sliding grinding, thereby realizing polishing, deburring, chamfering, removal of oxide layers and removal of marks equal to the entire goal. This process can bring excellent mirror effect to complex exterior surfaces and reduce roughness by 1-2 levels. Used for tool passivation, punch polishing, precision medical device polishing, coating impression polishing, engraving mold polishing and other fields.
Case: Polishing of medical molds
[Matériel médical Seiko]Mirror jet polishing: the secret to a leap in quality for medical molds
In medical mold manufacturing, the application of mirror spray polishing has the following important purposes:
1. Improve surface quality
Mirror polishing can significantly improve the surface finish of the mold and reduce micro-protrusions, scratches and burrs, which is especially important for the manufacturing of precision medical devices, because surface defects can affect the operation and biocompatibility of the product.
2. Improve wear and corrosion resistance
The polished surface of the mold is harder and smoother, which helps to improve the wear and corrosion resistance of the mold, thereby extending the life of the mold.
3. Improve product appearance
Polishing not only improves the surface quality of the mold, but also makes the final product have a better appearance, such as higher gloss and smoothness, which is very important for market competitiveness and consumer acceptance.
4. Promote unmolding
The polished mold surface can reduce friction during the production process, facilitating demoulding and improving production efficiency.
5. Meet strict medical standards
The medical industry has extremely high requirements for product safety and performance, and mirror polishing helps ensure that medical molds and resulting medical devices meet these strict standards.
