Laser Hardening Applications by Industry
productcate-1536-864
01.

Automotive Industry

Core automotive components like engine crankshafts, transmission gears, and brake discs endure severe wear under high-speed, heavy-load conditions. Laser hardening technology targets these pain points: it restores dimensional accuracy to worn gear tooth surfaces and brake disc friction surfaces while boosting surface hardness and wear resistance via precise phase transformation. This cuts equipment downtime by over 30% and extends the service life of key components, ensuring stable operation of automotive production lines and reducing maintenance costs.

02.

Construction Machinery Industry

Parts in construction machinery (excavator bucket teeth, loader shovel edges, hydraulic cylinder rods) suffer intense abrasion during earthwork and material handling. Laser hardening addresses this by repairing worn areas (e.g., uneven bucket tooth edges) and rapidly increasing surface hardness to HRC 58–62. This reduces component replacement frequency by over 50%, shortens equipment downtime, and achieves “cost reduction + efficiency improvement” for construction machinery operations.

productcate-2730-1535
productcate-2730-1535
03.

Mold Industry

Molds (stamping, injection, die-casting molds) are critical for manufacturing, with precision and durability directly impacting product quality. Laser hardening focuses on mold weak points: it repairs micro-defects on mold cavities and cutting edges while enhancing surface wear/corrosion resistance via martensitic transformation. This extends mold service life by 2–3 times, reduces replacement/maintenance frequency, and ensures consistency of molded products.

04.

Rail Transit

Rail transit equipment (train wheels, axles, track switches) endures continuous friction and impact during operation. Laser hardening tackles this by restoring geometric accuracy to worn wheel treads and axle surfaces, while forming a dense, wear-resistant layer. This reduces equipment maintenance frequency by over 40%, extends component service life, and ensures safety/stability of train operations.

productcate-2730-1535
productcate-2730-1535
05.

Oil & Gas Industry

Oil/gas components (drill pipe joints, wellhead valves, pump rotors) face harsh corrosion, sand erosion, and high-pressure environments, leading to sealing failure and reduced efficiency. Laser hardening enables “micro-level repair + performance enhancement”: it restores geometric precision to corroded/worn parts and forms corrosion-resistant, wear-resistant coatings on surfaces, returning equipment performance to near-new condition. This curbs downtime losses from component failure and guarantees continuity of oil/gas production.

 
Material System for Laser Hardening

In laser hardening processes, the choice of base material directly affects the hardening effect (e.g., hardness improvement, distortion control) and service performance of workpieces. Below is a summary of key characteristics for commonly used materials in laser hardening, including hardness range after treatment, applicable temperature scenarios, and core advantages, to provide reference for material selection in different application scenarios.

Export Packing & Logistics

product-1132-636

Non-Wooden Template Material & Structural Requirements

The export packaging of laser cladding equipment strictly complies with international quarantine and transportation standards. It fully adopts non-wooden packaging templates (preferring materials that meet the ISPM 15 International Phytosanitary Standards for Wood Packaging Materials, such as high-density plywood and composite fiberboard) to eliminate the cross-border quarantine risks that may be caused by solid wood materials. The selection of templates must meet the equipment's load-bearing requirements (each template has a static load strength of no less than 1500N/m²), and the joints are reinforced with galvanized steel straps to prevent structural loosening during transportation.

Packing Cushioning, Protection & Labeling Requirements

During packing, an EPE foam cushioning layer (with a thickness of no less than 50mm) is laid between the equipment and the template. Key components (such as the laser head and control cabinet) are additionally covered with waterproof PE bags. The outer wall of the box is clearly affixed with labels in accordance with export requirements (including equipment model, gross weight, center of gravity, and warning signs such as "Handle with Care" and "Keep Dry"), ensuring full compliance with the destination country's import packaging inspection standards.

product-1440-810
product-1706-959

In-plant Packing Process

The entire packing process of the equipment is carried out in a closed indoor workshop to avoid the impact of rain, snow, and dust during open-air operations. Closed trucks equipped with hydraulic lifting platforms are selected to ensure smooth loading and unloading of the equipment. If non-enclosed truck bodies (such as stake trucks) must be used due to transportation radius constraints, the equipment must be covered with a double-layer rainproof tarpaulin (the outer layer is PVC-coated rainproof cloth, and the inner layer is breathable moisture-proof film) after being loaded onto the truck. The edges of the tarpaulin are tightly fixed with nylon ropes, and the four corners hang down to the bottom of the truck body to prevent rainwater penetration.

Container Fixation Process

After the equipment is loaded into the container, the "three-point fixation" plan is implemented immediately—fixing the template to the container floor via expansion bolts at the bottom; using galvanized steel wires (with a diameter of no less than 8mm) to diagonally pull and fix to the hooks on the side walls of the container at the two sides; and using adjustable pressure rods to prop against the top plate of the container at the top (the contact end of the pressure rod with the equipment is wrapped with a rubber pad to avoid scratching the equipment surface). After fixation, a sway test is required (applying horizontal thrust manually, with the equipment displacement not exceeding 5mm) to ensure no displacement risk during bumpy sea or land transportation.

product-1773-997
product-1100-618

Full-Process Tracking and Control

Special personnel are assigned to follow up on the logistics process. From the factory shipment, port customs declaration, sea transportation to the destination country's customs clearance, the transportation status (including temperature, humidity, and location information) is recorded at each link. On-site photos are taken and retained at key nodes (such as container loading onto the ship and unloading at the port) to ensure full traceability and minimize the risk of transportation damage
