Are you having problems like the following? Click here to inquire

  • Material cannot be cleanly punched.
  • Currently unable to perform precision punching in trial and small lot production.
  • Currently unable to perform punching more easily and conveniently.

The“HANDHELD PUNCH for visual punching”from Nogamigiken Co., Ltd. will solve these problems!

For example... Punching work for lithium ion battery electrodes

Case1

Lithium ion battery research
— Punching coin battery electrode sheets —

Problem
Punches are used when prototyping coin-type lithium ion batteries, but there are problems during punching such as peeling of the electrode material (active material), appearance of burrs on the substrate, and inability to punch with satisfactory quality.
When using an ordinary punch...Burrs and peeling! With our HANDHELD PUNCH…No burrs or peeling!
Solution
The HANDHELD PUNCH cleanly punches thin foil materials, so punching can be done without any burrs or peeling of the electrode sheet on which the electrode material has been coated.

Case2

Measurement of amount of electrode material applied
to electrode sheet

Problem
When sampling for measurement amount of material applied to electrode sheet, part of the sheet is cut off by cutter and punched. Isn’t there a way to do punching work more efficiently?
Punching after cutting out with a cutter It is time-consuming... With our HANDHELD PUNCH… There is no need for cutting out with a cutter!Work can be done easily and trouble-free!Weight error of punching samples is less than 0.001g!Enables accurate measurement of amount of active material applied!
Solution
No need for cutting work, and punching can be done directly from the coating line!
Measurement of the applied amount of material can be done precisely and quickly.

Ultra-precise! Features of the Nogamigiken HANDHELD PUNCH

Outstanding sharpness

With outstanding sharpness achieved through ultra-precise finishing, the HANDHELD PUNCH enables clean punching without burrs or deformation. No minute fragments or other debris are produced, so there is no contamination (admixture of foreign matter).
This improves quality of the final product, increases testing precision and work efficiency, and reduces material loss.

Punching sizes can be ordered in 0.01mm units.
Please consult with us regarding odd shapes.

For the standard round and rectangular shaped products, size can be designated in 0.01mm units.
We can also handle other shapes. Please send us documentation indicating the desired shape.

Lightweight and compact for improved work efficiency!

The compact design is easy to handle, even in small or delicate hands.
(Weight of the tool body is approximately 200g and up.) Light weight is achieved through a design placing top priority on ease-of-work. The HANDHELD PUNCH is also ideal for doing punching work inside a glovebox.

The ultra-precise grinding and precision assembly technologies of Nogamigiken support the HANDHELD PUNCH

What makes the sharpness of the HANDHELD PUNCH possible is the ultra-precise grinding and precision assembly technologies which have been the core technologies of Nogamigiken since our founding. In particular, the HANDHELD PUNCH exploits ultra-precise grinding enabling parallel and orthogonal precision of 5/10,000mm and the know-how in precision blade fabrication we have cultivated in the more than 40 years since our founding. In this way, it enables punching—while minimizing burrs and deformation—of the previously difficult to punch materials such as thin foil materials, electrode sheets (cathode, anode, aluminum foil, copper foil), and separators.

Voices of our customers

  • “Every year, batteries are improving in functionality and performance, and quality issues such as burrs have become a major problem for electrode materials. However, the HANDHELD PUNCH from Nogamigiken produces no burrs and retains its sharpness, and that has been a tremendous help in our research and development labs. We have about 20 of these punches in my department, and I recommend them to other researchers.”Production technology engineer, battery manufacturer
  • “Quality in terms of burrs and peeling is far superior to products made by other companies, and punching can be done with the same quality no matter who does the work. At our company, we do work inside gloveboxes, and the light weight of the tool is extremely helpful.”

    Engineer, automobile manufacturer
  • “The HANDHELD PUNCH from Nogamigiken has the same quality as a die, but is extremely inexpensive compared to a die, and that’s a great help. Thomson dies can be made inexpensively, but they can’t attain the quality of the HANDHELD PUNCH. These tools are inexpensive but high quality, so we have many of them with various shapes.”
