JIS stands for Japanese Industrial Standards and is a widely recognised standard, heavily used in the automotive and industrial sectors. JIS B 5012 die springs provide consistent quality and performance for moulding and industrial applications.

Our JIS die spring range contains over 1,200 sizes, covering applications from high-deflection very light to super load requirements. The springs feature a rectangular wire cross-section and a high-performance E-COAT cataphoretic coating for excellent corrosion resistance and a durable, thin paint layer.

The load rating is associated with the colour of the spring, as follows:

• High Deflection Very Light: Ivory
• Extra Light: Yellow
• Light Load: Blue
• Medium Load: Red
• Strong Load: Green
• Super Load: Brown

Please note that different ranges may have variations in load rating and colour arrangements. If you need assistance selecting the correct load for your application, our team can provide guidance to ensure optimal performance.

Custom JIS Die Springs

If the standard range does not meet your specific requirements, JIS die springs can be manufactured to your exact specifications, including custom dimensions, load ratings, and finishes.
