"Manufacturing high-precision leaf springs by pressing and trial parts quickly to support development"

Do you have problems like this?
*The spring characteristics of trial precision leaf springs manufactured by pressing do not satisfy expected values.
 ⇒ To avoid the alteration of material elasticity by annealing at blank fusing by wire processing or micro laser processing
*Trial parts manufactured by a processing method different from mass-production parts are used for certification and evaluation.
 ⇒It is necessary to verify the etched cross sections (fine and corroded) of trial products with processed cross sections of mass-production parts.

Our company continues to provide product development customers who have such requests quickly with trial precision parts of pressed cross sections manufactured by a general-purpose punch pressing method.

Solutions to issues about precision prototype parts
Solution 1: General-purpose punch press (MERC)
Particularly when developing a product using precision leaf springs, it is necessary to perform an elasticity test of parts processed in a similar manner to mass production rather than prototyping.
A general-purpose punching mold or in-house single mold is NC-controlled for blanking with a difference not larger than ±0.01 mm. This has enabled speedy prototyping.
Solution 2: Supporting up to high-precision bending
Our company has been responding to needs for minimum-size bending by utilizing the single-action bending die design technology. We have become familiar with the characteristics of each spring material. As such, we can now design and create single-action dies at quick turnaround and set optimum conditions for mold tuning and part machining to provide traced trial products.
* Micro power supply terminal: C1720-H  t=0.12 Required accuracy: 0.003
