LISTEN brand sheet metal equipment plays a pivotal role in modern shipbuilding, delivering precision, durability, and efficiency for the fabrication of massive marine structures. These technologies address the industry's demands for high-strength components, corrosion resistance, and compliance with stringent maritime standards.
1. Hull and Structural Component Fabrication
Hydraulic Shearing Machines: Heavy-duty shears pre-cut thick steel plates (up to 30mm) for hull sections, bulkheads, and keel components. LISTEN’s machines ensure clean edges with ±0.5mm tolerance, minimizing welding preparation time for shipyard assembly.
Laser Cutting Machines: High-power fiber lasers cut complex curves in high-tensile steel (AH36/DH36) for bow thruster housings and propeller blade templates, achieving ±0.2mm precision to optimize hydrodynamic performance.
2. Deck and Superstructure Manufacturing
Hydraulic Press Brakes: CNC-controlled press brakes form large aluminum-magnesium alloy sheets into lightweight deck panels and radar mast supports. Adaptive tooling handles variable radii for curved staircases and hatch coamings, maintaining ±1° angular accuracy.
Punch Presses: Servo-driven punch presses mass-produce standardized brackets, ventilation grilles, and cable tray components from galvanized steel, ensuring corrosion resistance for offshore environments.
