Real applications from different industries
Incomplete cast cleaning led to severe tool wear during machining. Product pass rate was only 82%, with high customer complaint rate.
Recommended switching to S1.0 high-hardness steel shot (HRC 45-50), replacing worn impeller wheel and blades, and adjusting blasting time to 8 minutes.
Product pass rate increased to 96%, tool life extended by 40%, customer complaints dropped 75%.
Severe rust on large steel structures. Manual rust removal was too slow to meet deadlines, and quality didn't meet coating standards.
Recommended G1.2 steel grit with pass-through shot blaster, achieving Sa2.5 cleanliness and Rz 60-80μm roughness, fully meeting epoxy zinc-rich primer requirements.
Rust removal efficiency increased 5x, coating adhesion reached grade-A standard, project delivered on time with client approval.
Critical parts like gear springs failed fatigue life standards, frequent fractures in road tests led to batch recalls with significant losses.
Used S0.5 steel shot for surface strengthening, controlling coverage above 95%, arc height 0.35-0.45mmA, forming uniform compressive stress layer.
Part fatigue life increased 3x, zero fractures in road tests, reducing annual recall losses by approximately 2 million RMB.
High shot blaster failure rate, frequent unplanned downtime, fragmented spare parts sourcing with long lead times disrupting production schedules.
Established regular maintenance plan, bulk procurement of common spare parts (blades, impeller wheels, control cages, liners), and provided equipment inspection service.
Equipment failure rate dropped 60%, spare parts lead time reduced to 7 days, annual maintenance costs reduced 30%.
