東和電気 Product Lineup

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.

This product is a "vent filter (internal pressure release valve)" that features a silicone rubber with an insert-molded fluoropolymer membrane, covered with a protective resin plug. It maintains waterproofing from the outside while preserving air permeability inside a sealed container, and the airflow can be controlled according to requirements. Additionally, it has been certified by an external testing organization as a component that meets the waterproof protection grade (IP code) "IPX7." 【Features】 - Maintains waterproofing from the outside while preserving air permeability inside a sealed container - Airflow can be controlled according to requirements - Certified as a component that meets the waterproof protection grade (IP code) "IPX7" - Also possesses a venting function that can instantly release pressure - Maintains water resistance, air permeability, and dust resistance from the outside even after pressure release *For more details, please download the PDF or feel free to contact us.

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
