コアボックスジャパン Product Lineup

An optimal environment for pursuing answers: Point 1: A working space with a dew point temperature below -60℃ DP can be consistently achieved. Point 2: The use of an operating port with a throttling mechanism ensures both sealing performance and operability. Point 3: Our unique structure minimizes turbulence in the circulating air within the chamber. Point 4: The chamber section can be customized based on usage conditions.

Core Box Japan is a company that designs, manufactures, and sells secondary battery prototype equipment such as coaters and roll presses, as well as various industrial machinery and a range of electrical, electronic, information, and software products. Our "Roll Press" can accommodate everything from small test (lab) machines to large production machines. The roll width can be manufactured from a minimum of 150 mm, and the pressing force can exceed a maximum of 100 tons. We design to incorporate as many of our customers' unique systems as possible. 【Features】 ■ Pressing method: Pneumatic, hydraulic ■ Roll width: From 200 mm ■ Options: Roll heating system, unwinding and rewinding system, deviation correction device ■ Maximum pressing force can be manufactured up to 300 tons *For more details, please refer to the PDF materials or feel free to contact us.

The "Heat Sealer" from Core Box Japan is an air cylinder type heat sealer that can also be used for sealing the electrode tab section. The product is designed as a tabletop model. The sealing temperature can be used up to 200°C. We also offer optional dedicated stands and casters with adjusters. 【Features】 ■ Air cylinder type *For more details, please refer to the PDF document or feel free to contact us.*

Ideal for punching high-performance films, electrodes for secondary batteries, resins, sponges, gaskets, and more. Sales of Thomson blades only are also possible. The tabletop type does not require a specific installation location. Thanks to the use of inexpensive Thomson blades, size and shape are flexible. Utility is solely air (compressed air). Operated by an air-operated two-hand push switch. Surrounded by a resin cover with a standard air-operated door switch. 【Features】 ■ Capable of punching various shapes. ■ Minimizes blade chipping. *For more details, please refer to the PDF document or feel free to contact us.

Our "Precision Resistance Spot Welder" is an ideal product for welding the bottoms of cans for secondary batteries, relay contacts, and the lead wires for switch lamps/capacitors. We offer a variety of welding heads and electrode materials, including "transistor-type welding power supplies" and "DC inverter-type welding power supplies." Additionally, we accept sample testing. Please feel free to contact us. 【Features】 ■ A variety of electrode materials available ■ Sample testing available *For more details, please refer to the PDF document or feel free to contact us.

【Arbitrary Setting of Oscillation Start Trigger】 The oscillation trigger varies depending on the press type. Please select the press type according to your application. The press can also be prepared by the customer. (Sale of oscillator and horn section only is possible) 【After-Oscillation Function Equipped】 After-oscillation to detach the workpiece from the tool horn can be set for an arbitrary duration. 【Frequency Search Function】 You can find the optimal frequency for the tool horn and ambient temperature with a one-touch operation, avoiding tracking errors at the start of use. 【Diverse Lineup】 We offer oscillators ranging from 350W output types to a maximum of 3000W types. 【Support for Pre-Joint Testing】 We conduct pre-joint testing when considering a purchase. *For more details, please refer to the PDF materials or feel free to contact us.
