At the heart of our manufacturing operations is a powerful fleet of over 60 advanced production machines. We operate a diverse lineup of both high-end imported and domestic CNC spring forming machines, giving us the versatility to manufacture an incredible wire diameter range—from ultra-fine 0.02mm micro-springs for electronics to heavy-duty 16mm springs. Beyond spring forming, our facility is equipped with high-precision CNC lathes and mill-turn composite lathes to handle complex hardware components. To provide a complete, end-to-end manufacturing solution, we house a full suite of post-processing equipment under one roof, including: Heat Treatment Furnaces: For optimal material strength and durability. Shot Blasting Machines: To relieve surface stress and improve fatigue life. Wire Cutting & Spring Grinding Machines: For precise finishing and flat ends. With this extensive manufacturing setup, we are fully equipped to meet the vast majority of custom spring and hardware production needs, efficiently scaling from rapid prototyping to high-volume mass production.
Precision manufacturing requires uncompromising quality assurance. Our dedicated inspection laboratory is outfitted with industry-leading testing equipment to guarantee that every batch performs exactly as engineered. Our in-house testing capabilities include:
Tensile & Compression Testing Machines: To accurately verify load capacities, spring rates, and mechanical performance.
Hardness Testing Instruments: To ensure materials meet strict structural and strength requirements.
Flatness Testing Instruments: To guarantee perfect dimensional accuracy and alignment.
Surface Treatment Adhesion Testers: To verify that coatings and finishes are durable and long-lasting.
From the first coil to the final inspection, our advanced equipment and rigorous testing protocols ensure that your custom components are built to perform flawlessly.
