Precision tension spring — key benefits and features Reliable, defect finish: Outer rod is smooth and round with no sand holes or black spots, ensuring consistent fit and clean appearance in assemblies. Stable, even force: Uniform pitch and tight, accurately formed coils deliver even stress distribution and predictable rebound performance, reducing vibration and minimizing part wear. Durable stretchability: Made from quality raw materials with plasticity and good fatigue strength; resists deformation under repeated loading for long service life. Consistent texture and detail: Clear, uniform surface texture and precise manufacturing minimize variation between parts and simplify installation and inspection. Broad applicability: Designed to perform across multiple fields where consistent tension and durable spring action are required. How this solves common problems Prevents premature failure: Even stress distribution and good fatigue strength reduce breakage and extend maintenance intervals. Improves assembly quality: Smooth, defect exterior eliminates interference and cosmetic issues that can cause fit problems or part rejection. Delivers predictable performance: Tight, uniform coils provide repeatable rebound and load characteristics, aiding product reliability and system tuning. Typical applications Industrial machinery and automation: Reliable tension control and long fatigue life for conveyors, actuators, and mechanisms. Automotive and transport components: Consistent rebound and durable stretchability for small linkage, latches, and springs. Consumer and commercial equipment: Precise, defect springs for appliances, tools, and hardware where appearance and performance matter.
