Industries We Serve
JIALUN Springs provides custom springs, wire forms, and precision hardware components for smart electronics, luggage hardware, mobility products, robotics, and drone applications. We support rapid sampling, small-batch customization, surface finishing, and stable mass production.
Why Choose JIALUN for Custom Springs and Hardware Components?
With 27 years of manufacturing experience, a 7,000㎡ production facility, and experienced technicians, JIALUN supports custom spring, wire form, and precision hardware projects from sample development to stable mass production.
Small-Batch Customization
We support low-volume custom projects, sample trials, and early-stage product development, helping customers test structures and adjust designs before mass production.
Fatigue Life & Durability
We pay close attention to repeated-use performance, spring force stability, and long-term durability, especially for parts used in motion, return, locking, and support mechanisms.
Surface Finishing & Environmental Adaptability
We provide surface finishing options such as zinc plating, nickel plating, electrophoresis, powder coating, and passivation to improve corrosion resistance, appearance, and environmental suitability.
Dedicated Project Support
Each project is supported by dedicated sales, technical, production, and quality-control coordination. We help customers confirm drawings, samples, materials, tolerances, and production requirements more efficiently.
Fast Sampling & Design Revisions
For standard custom spring projects, samples can usually be prepared within 3–5 working days after drawing confirmation, with international express delivery arranged as needed. Multiple adjustment rounds are supported before mass production.
Stable Mass Production
From experienced machine setup to in-process inspection, we focus on dimensional consistency, stable performance, and reliable batch-to-batch quality.
