Handheld + automatic dual-purpose sandblasting machine is a multi-functional surface treatment equipment that takes into account mass production and special-shaped repair. One machine switches two operation modes, easily adapts to the sandblasting processing needs of large and small workpieces of different specifications, and provides flexible and efficient sandblasting solutions for metal processing, mold manufacturing, auto parts, hardware die casting, and steel structure supporting enterprises. As the source factory of sandblasting and blasting equipment, we rely on years of experience in equipment research and development and process landing to create this highly adaptable dual-purpose sandblasting machine, which solves the problem of sandblasting in many factories with large quantities of small parts and large special-shaped parts at the same time. There is no need to purchase multiple equipment separately, reducing equipment investment and workshop floor space costs.
The equipment has built-in multiple groups of programmable automatic sandblasting gun groups, with independent handheld sandblasting guns, mode switching is simple and convenient. In automatic mode, the spray gun can operate stably according to the preset stroke, sandblasting pressure, and processing time. It is suitable for rust removal, deburring, oxide layer removal, and coarsening before spraying of standard small pieces, batch hardware, die castings, and fasteners. Sandblasting parameters can be adjusted individually on the PLC control panel. The sand flow rate, injection angle, and processing time are controllable. The batch workpiece sandblasting texture is uniform, and the roughness consistency is strong. It stably guarantees the adhesion of subsequent painting, electroplating, and coating, and reduces the rate of defective products.
After switching to the handheld sandblasting mode, the operator can flexibly control the sandblasting gun to deal with areas that are difficult to be covered by the automatic spray gun such as large components, special-shaped molds, weld positions, and dead corners of the inner cavity. For large-scale sandblasting scenarios such as steel structural parts, large boxes, heavy-duty molds, and rack repair, the handheld gun can be fixed-point sand replenishment, local rust removal and renovation, and deal with various irregular surfaces, grooves, and gaps to solve the pain points that are difficult to clean up dead corners of traditional automatic sandblasting machines. The two modes are independently controlled by gas paths, which do not interfere with each other, and the production scheduling is more flexible. Small batch proofing, single-piece repair, and large-scale production can all be completed on the same equipment.
The whole machine adopts a closed cabin structure, and is equipped with a pulse dust removal and automatic abrasive recovery screening system. The operation dust is effectively collected to meet environmental protection production standards. The abrasive is recycled and consumables are reduced. The cabin body is lined with wear-resistant rubber protection to reduce the wear of high-speed abrasives on the fuselage and prolong the service life of the whole machine; the nozzle is made of wear-resistant boron carbide material, which is durable. It is suitable for a variety of abrasives such as white corundum, emery, glass beads, etc., and supports various sandblasting process requirements such as matte, bright, and rough rust removal. The fuselage structure is strong, the maintenance point layout is clear, and the daily filter element cleaning, seal replacement, and gas path maintenance are simple, which reduces the equipment shutdown maintenance time.
We support non-standard customization services. We can adjust the cabin specifications, number of spray guns, table load and transmission scheme according to the maximum size of the customer's workpiece, single batch production capacity, and material characteristics. At the same time, we provide free samples and process debugging guidance. We provide one-stop service from program communication, equipment production, on-site installation and debugging to later parts supply and fault technical support. This handheld automatic dual-purpose sandblasting machine takes into account automated production capacity and manual flexible processing. It is suitable for diversified sandblasting production needs. It is a cost-effective sandblasting equipment choice for small and medium-sized processing plants and large manufacturing workshops.
