【Product Specifications】
Product Name: Leaf Spring for Socket Contact
Material: C5210R-H (Phosphor Bronze)
Thickness: t0.1
Total Length: 4
Inner Diameter:
Both Outer Sides: φ1.3mm
Center Section: φ0.8mm
Slit Dimensions: Width 0.3 × 6 slots
Roundness Accuracy: Within 0.05
Processing Method: Progressive Curling Processing
Key Explanation
Curling processing refers to the technique of rolling a flat sheet into a cylindrical shape.
The product shown in the image is a tsuzumi (drum) shape, where the center diameter in the length direction is larger than the diameters at both ends. Additionally, it is also possible to process a tawara (barrel) shape, which has a similar structure.
We can handle various spring materials, including phosphor bronze, beryllium copper, and stainless steel (SUS).
We have also successfully developed even smaller-sized components.

The photo shows the hardening station of a reduction gear hold flange
induction hardening and reheating machine, seen from above.
The outer circumference of the disc-shaped workpiece in the center
is heated by the ring coil.
The workpiece is loaded/unloaded from under the coil.
After the workpiece is set, the jig raises the workpiece into the coil,
where it is heated at a very close distance.
After heating, the jig carries the workpiece down to the quenching position.
Quenching water is sprayed from the surrounding jackets
for quick and even quenching.
This machine is designed to achieve high hardening quality
by optimizing heating time, power, quenching time, and water flow.
The photo shows a reduction gear hold flange induction hardening
and reheating machine.
With one converter supplying power to three hardening machines,
this system is able to harden and reheat flanges of different specifications
in parallel.
※At Fuji Denshi, we refer to tempering as reheating to differentiate
from furnace methods.
A robot loads the workpiece from the front port.
Each machine is operated under separate settings to achieve
high productivity and quality.
The photo shows a precision micro-hole press component manufactured for the automated equipment industry.
Using progressive press processing, we punch φ0.05 micro-holes at a position 0.10 mm from the edge of laminated film material with a thickness of 0.03 mm, demonstrating high-precision edge processing capability.
Material: Laminated film

The photo shows a resin-made hexagonal screw component.
Designed for weight reduction, this part is molded from CFRTP as a metal replacement solution. In addition to external threads, internal threads are also formed by molding using a core mechanism, enabling complex thread geometries in a single process.
At Shinshu Yoshino Electric, we have developed a proprietary composite molding technology known as the Direct Fiber Feeding Injection Molding Method. By modifying the injection molding machine, continuous fibers are fed directly into the process, enabling the production of high-performance CFRTP components.
