DISA has custom-designed and delivered a high-performance mesh belt shot blasting machine for Xinan Technology, specifically engineered to address the surface treatment challenges of precision aluminum and ferrous alloy castings, including flat, thin-walled, and fragile components. Operating in a continuous straight-through mode, the system integrates automatic loading, unloading, and discharge conveyors, all orchestrated by an advanced PLC with part memory functionality to ensure a seamless and orderly production flow.
The core of the system is a robust metal mesh belt crafted from high-strength, wear-resistant manganese steel. This design ensures that workpieces remain isolated during transit through the blast chamber, effectively preventing collision damage or deformation of delicate parts. High-efficiency blast turbines are strategically positioned both above and below the conveyor, delivering synchronous, all-around coverage that completes deburring, cleaning, descaling, deflashing, and etching in a single pass, thereby significantly enhancing manufacturing consistency and throughput.
The machine features a comprehensive abrasive recovery and purification loop: spent media is collected at the base, conveyed via screw conveyor and elevator to a top-mounted air-wash separator, where clean abrasive is recycled to the storage hopper while dust and contaminants are diverted to a separate silo for disposal. Constructed with replaceable high-wear liners in critical zones, the unit comes pre-wired with centralized dust extraction ports, with an optional integrated dry cartridge dust collector available. This turnkey solution enables seamless integration into Xinan Technology’s automated production line, eliminating intermediate storage, minimizing logistics distances, and reducing both manual intervention and operating costs to achieve high-quality, cost-effective continuous manufacturing.
