According to the different type molding, it can be handling 1~3 6 meter moldings four sides in 30 seconds one-time.it adopts international advanced matrix-pressure gas jet principle, to ensure the mechanical principle of the effect of sandblasting in technically. To overcome the metamorphism phenomenon after sandblasting machine process, the technical requirements for equipment higher than the thickness of 0.8 mm, after sandblasting processed, the profile is not deformed.
