High-end Equipment / Shipbuilding / Energy Industry

Application Scenarios

• Core connecting components for high-end equipment such as industrial robots and CNC machine tools.
• Fixed fasteners for wind power and hydropower equipment (e.g., connecting bolts for wind turbine hubs and hydropower generator sets).
• Connecting parts for ship decks and engine rooms.

Core Production Characteristics

• Large-size & High-strength Production

   

  Mainly large-size fasteners from M8 to M36; some wind power bolts can exceed M50, with tensile strength ≥ 1000 MPa to withstand heavy loads of high-end equipment and alternating loads of energy equipment.

   

  Large-scale cold heading machines, forging presses, and optimized forging processes ensure uniform internal material structure. Heat treatment improves mechanical properties and avoids cracking or deformation in large-size products.
   
• Corrosion-resistant Materials & Optimized Processes

   

  To solve corrosion in marine (ships) and chemical (energy equipment) environments, corrosion-resistant materials such as duplex steel, Hastelloy, and titanium alloy are used to resist seawater, acid, and alkali media and extend service life.

   

  Surface treatments (anti-corrosion coating, anodic protection) and thread anti-corrosion treatment further enhance corrosion resistance and prevent loosening caused by thread corrosion.
   
• High Reliability & Long-life Design

   

  Anti-loosening and anti-falling structures (double nut locking, cotter pin fixing, thread sealant) ensure no loosening or disengagement under long-term high-frequency vibration and harsh environments.

   

  Fatigue tests, corrosion tests, and structural optimization reduce stress concentration, improve fatigue resistance, and meet long-term stable operation requirements of high-end and energy equipment.
   
• Mass Production Combined with Customization

   

  The industry requires both high-volume standard fasteners (e.g., ship deck bolts) and customized large-size / special-structure fasteners (e.g., wind turbine hub bolts).

   

  Flexible production lines balance automated mass production for standard parts and precision machining for customized parts. A strict quality inspection system ensures compliance with industry standards for every batch.
   

General Core Characteristics of CNC Machined Screws

• Ultra-high Precision:
   
  Standard tolerance ±0.01 mm, precision version up to ±0.001 mm, with precise, clearance-free thread fitting.
• High Consistency:
   
  Program-controlled, with high uniformity in dimensions, geometric form, and surface quality in mass production.
• Flexible Customization:
   
  No mold required; quick switching for non-standard pitches, special heads, multi-step shafts, and special groove types.
• Wide Material Compatibility:
   
  Capable of machining stainless steel, titanium alloy, aluminum alloy, copper alloy, high-temperature alloy, etc.
• Flexible Efficiency & Batch Size:
   
  Suitable for small-batch prototyping and medium-batch customization, with fast switching between single parts and multi-variety production.
