When it comes to manufacturing JIS standard springs, material selection plays a crucial role in performance, cost, and service life. Two of the most common choices are 65Mn carbon spring steel and 50CrVA alloy spring steel. While both meet Japanese Industrial Standard (JIS) requirements, their properties differ significantly, making each suitable for different applications. In […]

Why Compression Springs Are the Unsung Heroes of Your Machines Compression springs don’t just sit pretty—they take the brunt when machines go to work. They absorb shocks, cushion motion, and keep things bouncing back in place. Without them, your car’s suspension would feel like a rollercoaster gone rogue, and your gadgets might give up at

If you’re working with molds, presses, or any high-precision mechanical assemblies, chances are you’ve come across US Die Springs. They’re the unsung heroes that keep industrial tools running smoothly, absorbing loads, and ensuring reliability. But beyond their sturdy appearance lies a colorful secret: a clever color coding system that reveals everything you need to know

Introduction to JIS Die Springs If you’ve worked with molds or mechanical devices, you’ve probably encountered a crucial but often overlooked part: the die spring. Specifically, JIS die springs—heavy-duty compression coil springs conforming to the Japanese Industrial Standards (JIS)—are fundamental in the precision tooling and manufacturing industries. But what exactly are JIS die springs, and
