Product Description
Rapid Prototype Extension Spring Service for Low-Volume, Multi-Specification Validation & Dynamic Performance Testing
1.Tension Spring Quick Detail
Tingfeng Hardware is your professional engineering partner for tension springs. We specialize in transforming your tension requirements into mass-producible precision components, handling wire diameters ranging from Φ0.1-12mm. Leveraging 15 years of technical expertise, advanced European-style spring machines, and CNC forming equipment, we provide a one-stop service covering design review, prototyping, performance verification, and mass production. With ISO/IATF dual certification and an agile mold system, we promise rapid sample delivery (48 hours) and ensure stable and efficient mass production (500,000 pieces/day capacity), helping you meet market challenges.
2.Tension Spring Product Description
A superior tension spring's value lies in its performance stability and reliability throughout its entire service life. We are committed to this, achieving our goals through a systematic approach. First, we perform precise calculations based on your application load and space constraints to determine the optimal spring index and number of coils. Second, we rigorously select wires to ensure consistency in their chemical composition and mechanical properties. During manufacturing, we control the tightness of the winding to set a precise initial tension and perform post-forming treatments on the loops to eliminate microcracks. Finally, targeted heat treatments (such as low-temperature tempering) stabilize the internal structure, minimizing tension decay over long-term use. What we deliver is a thoughtfully designed and precision-machined force control element
3.Tension Spring Product Features & Advantage
|
Feature |
Advantage to You |
|
Systematic Design Methodology |
Adopts a logic of designing backwards from the application, ensuring spring parameters perfectly match your system, avoiding the dilemma of “works but not optimized”. |
|
Root-Cause Material Control |
Establishes cooperation with知名 steel mills, conducting spot checks on key material batches, eliminating product performance inconsistency due to material variation at the source. |
|
Process-Oriented Manufacturing Philosophy |
Believes that “quality is built in, not inspected in”, ensuring the inherent quality of the final product by optimizing each process step. |
|
Full-Lifecycle Data Support |
It can establish quality archives for key projects, recording data from materials to finished products, providing a basis for your product traceability and continuous improvement. |
