Elevate Battery Development with NOGAMI

From prototyping coin cells and laminate cells for electrode charge/discharge tests
to preparing samples for SEM observation,
we address the challenges of battery development with our tools
that provide unparalleled processing quality.

REASONS

Why Battery Developers Worldwide Prefer NOGAMI

Unparalleled processing quality

Meeting the high-quality standards of battery development, we precision-process not only common positive and negative electrode materials but also challenging materials like silicon negatives.

High Usability

Our product design is driven by the on-site needs of battery development, such as the continuous processing of numerous samples for charge-discharge cycle testing, and/or operations within a glove box.

Durable and Long-lasting

Smooth sliding of the upper blade with no play, high rigidity that withstands long-term use.
High durability and a long lifespan, trusted by international users.

REVIEW

User Testimonials

Burr-Free and Long-Lasting Precision

The HANDHELD PUNCH from Nogamigiken produces no burrs and retains its sharpness,
which is a tremendous help in our research and development lab works.
We have about 20 of these punches in my department, and I recommend them to other researchers.

Superior Quality and Ease of Use in Glovebox Work

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, the work has to be done inside gloveboxes, and the light weight of the tool is extremely helpful.

An engineer

Automobile manufacturer

We recommend NOGAMI punchers for anyone who requires reliable and precise sample cutting

The cutting of samples is easy and precise (regular edges, identical surfaces, …). The risk of sample damage from being snagged is now more limited and the samples are more homogeneous.

Excellent Quality

Even with a very brittle solid electrolyte with a very small diameter of 0.5 mm and no binder, excellent quality without burrs or chips can be obtained.
Since high-quality samples can now be obtained stably, our experimental accuracy and throughput have been greatly improved.

Frequently asked questions

FAQ

Round handheld punches with the following sizes can be delivered immediately. Please contact us using the form below for stock status.

Φ1.00 to 26.00 mm in 1 mm increments, Φ11.28 mm
*Clearance 4μm, alloy tool steel, no blade coating

For example, if you specify a punching diameter other than the above, such as Φ9.5 mm, or if you order a square handheld punch, the product will be build to order and the delivery time will be 5 weeks or longer. Please contact us for details.

Yes, we can lend you a demo machine (Φ10.00 mm, clearance 4μm specification) free of charge so that you can check the usability and processing quality of the Handheld Punch.

We have a service in which you can send your materials to us and have us carry out test processing (for a fee).
Our laboratory engineer will punch out your materials and compile a report, and then we will return the punched products and material scraps to you.

Yes, all of our products are priced in JPY (Japanese Yen), but we will quote the payment amount in US dollars or euros at the exchange rate at the time we receive your quote request.

The warranty period for each product is one year from the date of delivery.

Yes, it is possible if it is related to secondary batteries or needs for advanced material development (such as ultra-precision sample preparation for cross-sectional observation).

Depending on your needs, we can also assign engineers to work with you on a problem-solving project. Please feel free to contact us.
