"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
Solution 3: Quick handling of various materials and plate thickness
[Plate thickness] 0.001 to 0.64 mm [Processing materials] Phosphor bronze (C5191, C5210, C5210HP), Beryllium copper (C1720HMB), Titanium copper (C1990, C1990HP), Colson copper (C7025, NKC286, NKC286S, NKC388, etc.), Brass (C2680), Germal silver, Stainless steel (SUS304, SUS430), etc.
