The surface treatment process of Scissors lift table and industrial goods lift-shot blasting.

Shot blasting is the name of a mechanical surface treatment process. Similar processes include sandblasting. Shot blasting is a cold treatment process, divided into shot blasting cleaning and shot blasting strengthening. Shot blasting, as the name implies, is to remove surface oxide scale and other impurities to improve appearance quality. Common mechanical equipment using channel steel or C-shaped steel (such as Industrial freight elevator, Electric stacker lifter, Electric lift table, Electric scissor lifts) need shot blasting. Shot blasting is the use of high-speed moving projectiles (60-110m/s) to continuously impact the surface of the strengthened workpiece, forcing the target surface and surface layer (0.10-0.85mm) to undergo the following changes during cyclic deformation: 1. Microscopy The organization structure is modified; 2. The non-uniform plastic deformation of the outer surface layer introduces residual compressive stress, and the inner surface layer generates residual tensile stress; 3. The outer surface roughness changes (Ra Rz). After the surface shot blasting of hydraulic lift table and hydraulic goods lift: it can improve the fatigue fracture resistance of materials/parts, prevent fatigue failure, plastic deformation and brittle fracture, and improve fatigue life.
