3. Applications
Ceramic beads blasting media B80 can be used for watch cases and belt sandblasting.
The case of the watch divided by material, mainly including zinc alloy case, copper case, steel case and titanium case.
Ceramic beads is widely used in the sandblasting of watch cases and straps due to its smooth spherical appearance, good elasticity, high toughness and non-breakability. It can obtain a smooth and non-reflective satin texture, which greatly improves the texture of the product. .
The watch case in the above picture is finished with ceramic beads blasting media.
The sandblasted steel case and the sandblasted steel dial have the earthy minerality of the concrete exterior wall.
The one-piece stainless steel strap is also sandblasted, and the texture of the watch is born out of cement and minerals.
4. Applicable Equipment
Automatic sandblasting machineThe case crown can be sandblasted with an automatic sandblasting machine, using ceramic beads B80 as the sandblasting media, and using a multi-aperture swing nozzle to sandblast the case from all angles, so as to achieve no dead angle coverage.
Note: When the crown is sandblasted, the design of the fixture must meet the requirements. It is necessary to ensure that the product will not be blown off during sandblasting, and the root of the crown cannot be sandblasted, because the crown involves waterproof performance!
