All-Stainless Steel Wet Liquid Sandblasting Machine (Handheld/Automatic Series)

This stainless steel wet sandblasting machine is a surface treatment system that uses a water-abrasive slurry as the blasting medium. The core working principle involves a slurry pump that delivers the uniformly mixed abrasive-water slurry to the blast gun, while compressed air serves as the accelerating power, entering the gun through an air hose to accelerate the slurry before it is ejected through the nozzle at high velocity onto the workpiece surface. Unlike traditional dry blasting, wet blasting places the abrasive in water and uses a slurry pump together with compressed air as the power source to propel the slurry through the blast gun at high speed, achieving surface cleaning and finishing. The entire machine body is manufactured from 304 stainless steel, making it robust, durable, and completely corrosion-resistant. This series covers both cabinet-type handheld models and automatic conveyor-type models—handheld units are ideal for single-piece small-batch precision processing, while automatic units are suited for continuous high-volume production—offering solutions for customers with different capacity and process requirements.

In terms of manufacturing quality and structural integrity, the main cabinet of this stainless steel wet sandblasting machine is welded from 2.0~5.0mm thick 304 stainless steel plates. The inner walls of the work chamber are lined with wear-resistant rubber sheets to effectively protect the cabinet from abrasive impact. The professionally manufactured slurry pump, blast gun, and worktable are all lined with wear-resistant polyurethane material, and the blast gun nozzles are made of high-grade boron carbide for extended service life and reliable performance. The slurry pump is a high-efficiency polyurethane pump with strong abrasion resistance and durability, continuously agitating during operation to ensure thorough mixing of abrasive and water without clumping, sedimentation, or blockage. The entire machine features a compact design with simple operation, controlled by a foot pedal for safe and reliable use. The compact models can be customised into various automatic or manual sandblasting systems according to customer workpiece requirements.

The performance advantages and application value of this stainless steel wet sandblasting equipment are substantial. First, dust-free and environmentally friendly – operation produces no floating dust, completely eliminating the environmental pollution and health hazards associated with dry blasting. Second, no temperature rise or discolouration – the cooling effect of water during wet blasting prevents workpiece surface temperature rise and discolouration, making it particularly suitable for temperature-sensitive materials such as stainless steel, aluminium alloys, and titanium alloys. Third, superior processing quality – the blasting effect is finer and more aesthetically pleasing than dry blasting, producing matte or diffuse reflective surfaces that enhance product quality. Wet blasting offers high efficiency with low abrasive consumption, improving surface smoothness and strength. Fourth, wide abrasive compatibility – suitable for various abrasive types and particle sizes, including micro-abrasives for precision workpiece surface treatment. Fifth, flexible rust prevention – rust inhibitors can be added to the blasting liquid to effectively prevent rusting of ferrous workpieces.

In terms of application scope, this stainless steel wet sandblasting machine is widely used for: surface finishing of precision moulds, electronic components, medical devices, cutting tools and gauges, piston rings, aerospace parts, aluminium alloys, titanium alloys, and stainless steel workpieces. Specific applications include: cleaning of oxide scale, residual salt, moulding sand, oil contamination, rust, carbon deposits, mould release agents, welding slag, paint films, and coatings from heat-treated parts, welded components, castings, and forgings—achieving cleaning quality up to Sa3 grade; removing微小 burrs and surface residues from machined parts; surface finishing of stainless steel parts to achieve matte or diffuse reflective surfaces; finishing of complex-shaped, high-precision, low-roughness parts; and refurbishment of old parts and mould cleaning without damaging mould surfaces or compromising precision. With its comprehensive advantages of dust-free operation, non-damaging processing, and fine finishing quality, this all-stainless steel wet liquid sandblasting machine has become the preferred choice for surface treatment of stainless steel, aluminium alloy, and other precision workpieces.
