after the prototype model is processed by the machine, some surface treatment processes need to be done, which can make the effect of the prototype surface more beautiful, let's introduce the sandblasting process to you. After sandblasting, the surface will have a layer of sand and granular effect, increasing the sensitivity, making the prototype sample look high-end atmosphere.

The sandblasting process uses compressed air as the driving force to form a high-speed injection to shoot the spray to the surface of the workpiece that needs to be treated, the surface changes. Due to the impact of abrasive on the surface of the workpiece and the cutting effect, the surface of the workpiece gets a certain cleanliness and different roughness, and the mechanical properties of the surface of the workpiece are improved.

spray: copper ore, quartz sand, Diamond sand, iron sand, sea sand, etc. The spray used for sand blasting in the prototype model is quartz sand.

sandblasting treatment can be arbitrarily selected between different roughness, and other processes cannot achieve this. Manual polishing can make the wool surface but the speed is too slow. If the chemical solvent is cleaned, the surface is too smooth to facilitate the coating bonding.
