Tower-type joint, stainless steel M5 adjusting screws, precision arc rings, custom-made by CNC processing

1. Aerospace (The Most Demanding Scenarios)

• Core Applications:
   
  Aircraft wing / fuselage structural connections, engine component fixation, satellite / rocket cabin assembly, and airborne equipment fastening.
• Scenario Characteristics:
  • Extreme working conditions: Withstand temperature differences from -55℃ to 300℃, high-frequency vibration, strong impact, and alternating loads.
  • Lightweight priority: Extensive use of titanium alloys and high-temperature alloys to reduce weight while ensuring strength.
  • Ultimate precision: Thread tolerance ±0.005 mm, strict geometric tolerances, in compliance with AS9100 aerospace quality standards.
  • Zero-failure requirement: A single screw failure may cause a major accident, requiring 100% full inspection and full-process traceability.
   

2. Automotive Manufacturing (Equal Emphasis on Scale & Precision)

• Core Applications:
   
  Engine block / crankshaft fastening, transmission components, NEV battery packs / motor housings, and chassis suspension systems.
• Scenario Characteristics:
  • High strength + high temperature resistance: Engine screws must withstand temperatures above 300℃ and severe vibration; commonly made of 42CrMo and alloy steel with heat treatment.
  • High volume + consistency: Mass production at the million level, dimensional consistency ±0.01 mm, ensuring assembly interchangeability.
  • New energy trend: Battery pack screws require insulation, lightweight, and corrosion resistance; the proportion of aluminum alloy / stainless steel materials is increasing.
   

3. Consumer Electronics & Semiconductor (Ultimate Miniaturization & Precision)

• Core Applications:
   
  Internal structures of smartphones / laptops, micro-fastening for smart watches / earphones, and fixation for semiconductor equipment chambers / wafer carriers.
• Scenario Characteristics:
  • Ultra-miniaturization: Minimum M0.8~M1.6 micro screws, thread precision ±0.001 mm, head size only 0.5~1.5 mm.
  • Ultra-thin wall & complex head types: Adapt to compact spaces; common designs include Torx, hex socket, and non-standard special-shaped heads.
  • High surface requirements: Ra ≤ 0.8 μm, burr-free; commonly treated with anodizing, nickel plating, etc., for appearance and rust prevention.
   

4. Medical Devices (Biological Safety & High Precision)

• Core Applications:
   
  Orthopedic implant screws (spine / joints), surgical instrument fastening, and internal component fixation for medical equipment (CT / MRI).
• Scenario Characteristics:
  • Biocompatibility: Made of Ti-6Al-4V ELI, 316LVM medical stainless steel, non-toxic and non-allergenic, in compliance with ISO 13485.
  • Ultra-high cleanliness: Surface Ra ≤ 0.4 μm, produced in cleanrooms, free of oil and particle contamination.
  • Customized adaptation: Threads and head types customized according to human bone structure for accurate implantation and fixation.
   

5. Industrial Automation & Precision Instruments (Stability & Versatility)

• Core Applications:
   
  Fastening for robot joints, servo motors, optical instruments, sensors, and high-end machine tool components.
• Scenario Characteristics:
  • High rigidity + low loosening: Ensure long-term operational accuracy; commonly use lock threads and locking washers.
  • Multi-variety, small-batch: Rapid model change, adapting to flexible production requirements of automated production lines.
