Wire Selection

Currently, the wires used by this company include Japan's piano wires (German Angel piano wires), high-tension steel wires, stainless steel wires, phosphor bronze wires and general steel wires.

• Wires with diameters over 0.08mm is used for multi-layer processing and fabrication for making compressive springs, tension springs and torque springs.
• During the manufacturing process, all wires are strictly tested to ensure the product performance and specifications are met to maintain a high quality level. During the test, the advanced computer Spring Force Tester, Tension Tester, Torque Tester and projector are used to ensure the quality and the "zero-defect" requirement.
• The quality is further guaranteed under the support of fully-automated production, monitoring and simplified system.
• The wire selection concerns much with the spring force and service life:
• SWC Hard-drawn Carbon-base Steel Wire (80c) : Homogeneous and stable hardness of the wire is in presenting high-precision spring for the manufacturers.
• SWP Piano Wire : Homogeneous hardness of the wire in presenting stronger spring force and higher stability
• SUS Stainless Steel Wire : Nickel-plated surface treatment on top of which, further rustproof finishing can be performed as required.
• PBW Phosphor Bronze Wire : Bright surface finishing in presenting satisfactory wire guiding rate and elasticity.

Plate Selection

The plate selection concerns elasticity, strength and corrosion resistance. Listed below is a comparison of characteristics of several plate materials:

• SUS301
  SUS 301 has better strength and elasticity and the surface is also more rust-resistant.
  SUS 304 is applicable for the environment using stainless steel and heat-resistance steel.

• Copper
  • Bronze
    Exhibits higher strength, ductility, drawability and electroplating, which is suitable for drawn-fabricated products.
  • White Copper
    Exhibits better fatigue endurance and has more satisfactory corrosion resistance against sea water and is suitable for high-temperature environments.
  • Phosphor Bronze
    Exhibits satisfactory ductility, elasticity, fatigue endurance, corrosion resistance and wire guiding performance.
  • Beryllium-Copper
    Exhibits better ductility, elasticity, fatigue endurance, corrosion resistance and wire guiding performance.
  • Iron/Carbon Steel
    Iron, carbon steel and tooling carbon steel SK5, SK7 are easier for fabrication and are suitable for various types of punching parts.
  • Aluminum
    Being light in weight, aluminum is suitable for externally enclosed parts and drawn-forming items.
