Sandblasting and Microblasting Machines

Treat all your parts to the highest industrial quality

What exactly are we talking about?

Robot de sablage

Sandblasting and microblasting are industrial surface treatment techniques that involve projecting an abrasive at high speed using compressed air through a nozzle. This technology is used for deburring, achieving surface roughness, or for aesthetic finishes such as matting, satin finishing, or cleaning.

These operations are performed without altering the dimensional integrity of your parts and can be done either fully or selectively. Common abrasives used depending on the process include glass beads, zirconia, corundum, plastic beads, and bronze powder.

Sandblasting and Microblasting Technologies

Depending on the surface condition or the desired aesthetic finish, various types of sandblasting or microblasting technologies can be implemented.

VACUUM BLASTING​

Vacuum Blasting (also known as Venturi sandblasting) uses an abrasive introduced into an accelerated projection system with compressed air. 

The media can easily be recirculated with the removal of dust and fine particles. The use of tungsten carbide nozzles with diameters of 4, 6, or 8 mm allows for processing large areas at pressures ranging from 1 to 5 bars.

PRESSURE BLASTING

Pressure Blasting uses a media pressurization tank. This abrasive tank is mounted on an electro-vibrator system. 

The vibration intensity is adjustable to dose the ideal abrasive flow to the nozzle, with ratios ranging from 1 to 10. The use of tungsten carbide nozzles ranging from 1.2 to 1.8 mm allows for various combinations to blast smaller parts. The machines also feature separate vibration and pressure settings (1 to 6 bars), as well as the ability to protect certain areas of the parts.

In the medical industry, microblasting or micro-sandblasting is used to achieve a surface roughness that enhances the osteointegration of implants.

Sandblasting is also used for aesthetic purposes in the watchmaking industry, with a satin or matte finish on cases, backs, and bezels (glass beads) or on bridges and plates (bronze powder).

It is also used in deburring parts made of PEEK, plastic (connectors), or in satin finishing mechanical parts.

For post-processing of parts from additive manufacturing methods such as metal powder bed fusion, DLP, or FDM, sandblasting/grit blasting is often used to remove powder, smooth the surface, and achieve functional surface roughness.

FAQ

Sandblasting cycle times can vary from 15 seconds to several minutes, depending on the size of the part and the desired result.
For example: 1 million dental implants, 200,000 hip stems, or 20,000 3D-printed titanium plates.
Our cells are designed to operate for at least 12 hours.

Commonly used media in our cells include: zirconia, glass beads, corundum, bronze powder, plastic beads, and biphasic HA.

Changing the media is straightforward with a blowgun and vacuum and takes about 5 to 10 minutes.

The sealing system between the robot and the cabinet minimizes dust accumulation. A daily blowgun and vacuum cleaning are sufficient to maintain a clean cell.

Wear parts include sandblasting guns and nozzles, hoses, sealing bellows, and parts in contact with the sand (touches, gloves, suction tips). The lifespan depends on the media, pressure, and materials used. Every effort is made to minimize spare parts volume.
