This high-pressure manual sandblasting machine is a cabinet-type surface treatment system that operates on the pressure-fed (pressurized) blasting principle. Its core component is a sealed pressure vessel that can withstand high internal pressure. Compressed air builds up working pressure inside the tank, forcing the abrasive media through the abrasive valve into the blast hose, and then through the nozzle at high velocity onto the workpiece surface. The impact and cutting action of the abrasive remove rust, scale, burrs, coatings, and create the desired surface profile. The machine features single-station manual operation, with the operator controlling blasting start/stop via a foot pedal or manual pneumatic valve. The blast gun is either hand-held or mounted on a bracket for directed blasting. This series can be configured in either suction-type (standard pressure) or pressure-fed (high-pressure) mode. Suction mode is suitable for routine surface cleaning and finishing, while high-pressure mode delivers stronger impact force and higher cleaning efficiency—one machine meeting diverse process requirements.
In terms of manufacturing quality and structural integrity, the main cabinet of this manual sandblasting machine is fabricated from high-quality cold-rolled steel plates of no less than 2.0~3.0mm thickness, with interior and exterior surfaces finished by electrostatic powder coating for excellent corrosion resistance and impact protection. The front of the work chamber features a large explosion-proof tempered glass observation window, allowing the operator to monitor the entire blasting process in real time. The door can be configured as front-opening or side-opening based on customer requirements. The machine is equipped with an independent dust collection system, available in baghouse or cartridge filter type, achieving over 98% dust collection efficiency to effectively control dust pollution. A cyclone separator is also incorporated to precisely separate reusable abrasive from fine dust, maximising abrasive conservation. The blast gun features a high-quality aluminium alloy body with a high-wear boron carbide or tungsten carbide nozzle, with inner diameters ranging from φ6 to φ12mm as required. The control system is simple and reliable, using a foot pedal or manual pneumatic valve to start and stop blasting. The entire machine features a novel design, easy operation, and low energy consumption.
The performance advantages and application value of this high-pressure manual sandblasting machine are substantial. First, high cleaning efficiency and strong impact force – the pressurized high-pressure manual sandblasting machine delivers stronger cleaning capability compared to suction-type models, with working pressures up to 0.8MPa, ideal for removing stubborn scale and heavy rust layers. Second, automatic abrasive recycling – blasted abrasive is automatically recovered via the cyclone separator and returned to the storage hopper for reuse, significantly reducing abrasive consumption costs. Third, flexible and convenient operation – manual control allows operators to adjust gun angle and distance at any time according to workpiece shape and blasting requirements, making it ideal for small-batch, multi-variety production scenarios. Fourth, environmentally friendly dust control – the high-efficiency dust collection system concentrates dust after filtration, with emissions meeting environmental standards. Fifth, wide application range – this machine can clean rough surfaces, remove scale, residual salt, and burrs from forgings, castings, welded parts, heat-treated parts, stampings, and machined components. It is suitable for pre-treatment before painting and electroplating, as well as for glass bead peening for surface strengthening and decorative finishing.
In terms of application scope, this manual sandblasting machine is widely used in: mould manufacturing (cleaning and matte finishing of shoe moulds, rubber moulds, glass moulds, electroplating moulds, etc.); metalworking (scale removal and weld slag cleaning from castings, forgings, welded parts, and heat-treated components); pre-treatment before surface finishing (surface cleaning and activation before electroplating, painting, and oxidation to improve coating adhesion); electronics (deflashing of electronic parts and magnetic cores); hardware products (rust removal, degreasing, and refurbishment of old parts); non-metallic materials (surface engraving, frosting, and perforation of glass, stone, ceramics, and acrylic); plastic products (deflashing and surface texturing). With its simple structure, easy operation, high efficiency, and low cost, this cabinet-type pressurized high-pressure manual sandblasting machine has become an indispensable surface treatment solution for small-to-medium workpiece single-piece and small-batch production, as well as maintenance and repair applications.
