Automotive, high-speed rail, aerospace, wind power, foundry & heavy industry
Industry Applications
04 · Multi-industry application expansion
One technology platform, five industries
The same disciplines of cleanliness, roughness and residual stress — tuned to each production reality.
01 · Automotive
Precision strengthening for automotive
Gear & transmission shot peening. High-velocity shot implants a residual compressive stress layer on gear teeth, significantly improving bending and contact fatigue strength, anti-scuffing capability and transmission service life.
Hot-formed A/B pillar blasting. For ultra-high-strength steel A-pillars, B-pillars and impact beams: removes oxide scale, creates optimal roughness for coating adhesion and improves crash-structure impact resistance.
Crankshaft & connecting rod strengthening. Controlled compressive stress suppresses micro-wear and fatigue crack propagation, meeting extreme-duty reliability and durability specifications of modern engines.
Gear shot peening · Surface refinement — residual compressive stress, fatigue life and safety structures.
02 · High-speed rail & railway equipment
Rail equipment, renewed and protected
Railway freight renovation. Bogies, couplers and brake discs develop rust and oxide layers after extended service; dedicated shot blasting removes contaminants, re-establishes a dense protective layer, enhances paint adhesion and extends maintenance intervals.
High-speed train body precision cleaning. For EMU carbodies and aluminum alloy structures, controlled blasting achieves uniform Sa 2.5 cleanliness with precise roughness, providing the ideal primer substrate for long-term corrosion protection across climate zones.
From freight fleet renovation to EMU carbody finishing — controlled blasting that performs across climate zones and decades of service. High-speed rail · Freight car · Safety.
03 · Aerospace
Aerospace structural components
Landing gear & wing skin peening. For aviation-grade aluminum alloys and high-strength alloy steels, precision shot peening of landing gear gear-ring outer circles and wing skin panels implants controlled compressive stress and improves surface integrity.
Aero-engine blade peening. Precision shot peening of aero-engine blade components introduces compressive residual stress, enhancing fatigue performance of parts that operate under extreme cyclic loading.
Aerospace-grade reliability. Controlled shot stream parameters meet exacting aerospace requirements for fatigue fracture resistance and stress corrosion cracking resistance in flight-critical structures.
Aero-engine components · Precision peening — aerospace grade, fatigue resistance, stress corrosion.
04 · Wind power & power equipment
Large-scale anti-corrosion for energy structures
Wind turbine towers. Continuous pass-through lines remove hot-rolled mill scale and welding spatter from wind tower sections, achieving Sa 2.5 cleanliness with a 30–75 μm anchor profile — the precise substrate epoxy primer adhesion requires.
Transformer & transmission structures. Transformer oil tanks and high-voltage transmission towers receive the same rigorous large-scale pretreatment, ensuring a clean, uniform surface across critical power steel structures.
30-year infrastructure protection. The Sa 2.5 clean surface foundation helps guarantee corrosion protection life of more than 30 years for critical power infrastructure. Wind power · Large-scale anti-corrosion.
05 · Foundry & heavy industry
Foundry & general heavy industry
From small automotive castings to multi-ton steel castings and petrochemical pipe sections — automated cleaning that preserves dimensional tolerances.
Foundry cleaning. Hook-type, crawler-type and overhead conveyor machines handle everything from small automotive castings to multi-ton steel castings — removing oxide scale, flash, burrs and core sand in one automated cycle.
Tolerance-safe surface control. Surface roughness controlled to GB/T 13307-2012 standards, providing the mechanical key for painting and powder coating while preserving dimensional tolerances.
General heavy industry. Continuous pass-through and overhead conveyor lines serve engineering machinery structures, petrochemical pipe sections and shipping containers with efficient automated cleaning. Custom blast arrangements ensure uniform Sa 2.5 coverage on complex geometries, meeting heavy-load surface quality and anti-corrosion requirements for high-strength steel.
