The tilting drum shot blasting machine is perfect for surface treatment of small and medium-sized castings and forgings. It is mainly engineered to clean thin-walled, tiny and irregular workpieces with minimal collision damage, and can also carry out surface strengthening for standard parts. It is a general-purpose machine widely applied in foundry, forging and hardware processing industries. Its specific applications fall into four major categories, covering the full workflow from pre-treatment to finishing:
- Surface Cleaning of CastingsFor small and medium-sized cast iron, cast steel and aluminum alloy castings, this machine removes surface molding sand, core sand, sprue and riser residues, clears casting mill scale and bonded sand. It improves the surface finish of castings and provides fundamental pre-treatment for subsequent painting and machining processes. Suitable for bolts, nuts, small valve bodies, pump housings and other cast components.
- Removal of Forging ScaleIt processes small and medium-sized carbon steel and alloy steel forgings, efficiently stripping high-temperature forging scale, flash and surface burrs generated during hot forging. This prevents mill scale from impairing the dimensional accuracy of subsequent heat treatment and delivers smoother surface texture for forgings. Ideal for small shafts, gear blanks, forged joints and other forged parts.
- Special Processing for Thin-Walled or Irregular Small PartsIt solves jamming and collision defects that often occur with traditional shot blasting equipment (track-type, horizontal drum machines) when processing thin small workpieces. Suitable for spring steel sheets, thin stamped parts and precision miniature irregular components. It completes surface cleaning without scratching or damaging workpieces, preserving their dimensional and structural integrity.
- Surface Strengthening & Stress ReliefControlled abrasive blasting strengthens the surface of fatigue-prone small and medium workpieces, boosting their fatigue resistance and corrosion resistance. Meanwhile, it eliminates localized stress concentrations formed during casting or forging. Recommended for small mechanical parts and standard hardware components with high durability requirements.
