Surface Pretreatment

Application objects: Large structural parts such as body frames, jibs, buckets, and pins of excavators, loaders, bulldozers, etc.

Rust and scale removal: Eliminate oxide layers, rust, and residual impurities on the surface after welding, forging, or heat treatment.

Roughness optimization: Form uniform roughness through steel shot impact to enhance the adhesion of subsequent coating (such as painting, plastic spraying) and extend the anti-corrosion cycle.

Stress elimination: Alleviate residual stress generated during welding or processing, reducing the risk of deformation.

Surface Strengthening

Application objects: Precision transmission components such as gearbox gears, drive shafts, and bearings. Functions:

Surface strengthening: Shot blasting creates compressive stress on the surface layer, improving fatigue strength and wear resistance, and extending the service life of components.

Deburring and finishing: Remove burrs and micro-defects after processing, improve surface finish, and reduce frictional loss.

Improving Surface Roughness

Application objects: Core engine components such as crankshafts, connecting rods, and cylinder blocks. Functions:

Strengthening and cleaning: Shot blasting can refine grains, enhance material strength, and remove residual sand and oil stains from casting or processing.

Eliminating stress concentration: Reduce the risk of fatigue cracks, especially suitable for high-speed rotating components.

Remanufacturing and Maintenance

Application scenarios: Renovation of old equipment, repair of key components (such as pins, gears). Functions:

Old coating stripping: Quickly remove aged paint or plating for easy repainting.

Damage detection: After shot blasting, surface cracks, wear and other defects can be visually inspected.
