Towa Group products

These are products from the Towa Group handled by Towa Electric.

Deep drawing process and corner drawing process

We will achieve difficult shapes for processing and drilling holes on the sides in sequential sending press!

At Towa Electric Co., Ltd., we handle "deep drawing processing and corner drawing processing." By applying pressure from a specific direction to the material, we can produce seamless metal products such as cylinders, square tubes, and conical shapes without welding or cutting. Additionally, leveraging the features of transfer presses, we can also perform punching and bending on the sides within the mold. 【Features】 ■ Capable of forming the desired shape with fewer processes ■ High productivity, suitable for mass production ■ Long mold lifespan, keeping costs low ■ Containers can be made from a single sheet of thin metal, resulting in no seams, preventing leaks of liquids or gases, while also enhancing aesthetics and strength *For more details, please refer to the related links or feel free to contact us.

Vent filter (internal pressure relief valve) for battery manufacturing

Safely discharge gas from inside the battery and shut out external influences!

In the battery manufacturing industry, safety and durability are the top priorities. In particular, properly venting gases generated inside the battery and preventing the intrusion of moisture and foreign substances from the outside are essential for maintaining product performance and ensuring safety. If gases are not properly vented, it can lead to battery swelling or explosion. Our vent filter (internal pressure release valve) instantly releases pressure inside the battery and blocks external influences, addressing these challenges. 【Application Scenarios】 - Lithium-ion batteries - Lead-acid batteries - Nickel-hydride batteries 【Benefits of Implementation】 - Extended battery life - Improved safety - Enhanced product reliability
