From design to manufacturing! A comprehensive solution for battery exterior components by Okita Manufacturing.

From design to manufacturing! A comprehensive solution for battery exterior components by Okita Manufacturing.

We provide one-stop solutions for concerns related to battery components, such as cases and lid assemblies! We will assist you from the design stage. Recommended for reducing initial costs as well.

At Daibei Manufacturing, we propose a comprehensive solution for battery exterior components, delivering welded structural battery cases and lid assemblies as a set. 【Product Features】 ■ Capable of handling prototypes and small-lot mass production! We do not use expensive stamping molds for the cases, which helps reduce initial costs, making it suitable for prototype to small-lot mass production (around a few thousand units per year). ■ Able to accommodate detailed requests! We provide a one-stop service from design to material procurement and manufacturing, allowing us to smoothly respond to small changes. ■ Good fit and airtightness The fit between the case and lid is carefully checked during production, ensuring no issues. Additionally, we conduct helium leak tests on all units of the case and lid assemblies to guarantee airtightness. If you have any concerns regarding battery components from the development to mass production of lithium-ion secondary batteries, please feel free to consult us. 【Manufacturing Achievements】 Cases (aluminum, stainless steel, titanium), sealing plates, current collectors, terminals, safety valve processing, rivet fastening 【Examples of Applications】 Prototyping to mass production of battery components for special applications such as aerospace Prototyping and development of battery cells for HV/EV applications.

【Proven for aerospace applications!】SUS and aluminum battery case

【Proven for aerospace applications!】SUS and aluminum battery case

Reliable and safe 'press-bent and welded battery cases' widely adopted in the aerospace and space industries! Additionally, we achieve low prices without the need for a die.

By using metal sheet press bending and welding instead of expensive die forming, we can accommodate both prototyping and mass production with short lead times. Despite being a welded structure, the fit with the lid is also good, and since we conduct helium leak tests on all units, the airtightness is guaranteed. We also manage special process certifications and traceability according to your requirements. The weldable plate thickness ranges from approximately 0.1 to 2.0 mm, with the most common being welded products in the range of 0.2 to 0.8 mm. Additionally, welding for safety valves is possible even below 0.1 mm. We also accept welding cases for lithium batteries and capacitors. 【Advantages of Welding and Bending Processing Without Using Dies】 ● Lower costs as expensive dies are not used ● Fast delivery from consultation to delivery since there is no die production ● High quality adopted in aerospace and defense industries * JIS Q 9100 certification obtained (Shimamoto Factory, manufacturing special battery parts for civil aircraft and space) * For more details, please contact us.

No need for a die! Airtight stainless steel case [Short delivery time & low cost]

No need for a die! Airtight stainless steel case [Short delivery time & low cost]

[Ideal for Prototyping] No need for drawing dies since it's made by bending and welding! Achieves short delivery times and low costs while ensuring airtightness! Flexible response to changes in dimensions and plate thickness!

Since we manufacture using metal sheet press bending and welding without using expensive molds, we can accommodate both prototyping and mass production with short lead times. Despite being a welded structure, the fit with the lid is also good, and we conduct helium leak tests on all units, ensuring airtightness. We also manage special process certification and traceability according to your requirements. The weldable plate thickness ranges from approximately 0.1 to 2.0 mm, but we primarily handle welded products in the range of 0.2 to 0.8 mm. Additionally, for welding safety valves, it is possible even with thicknesses below 0.1 mm.

Titanium welding battery case

Titanium welding battery case

Non-magnetic! Higher corrosion resistance and strength compared to aluminum! Can also be used for medical applications.

Titanium is recommended for customers considering "lightweight," "compact," and "strength improvement" of battery cases due to its properties. It also has minimal impact on the human body, making it ideal for medical applications. Since we manufacture using metal sheet press bending and welding without expensive die molds, we can accommodate both prototyping and mass production with short lead times. Despite being a welded structure, the fit with the lid is also excellent, and we conduct helium leak tests on all units, ensuring complete airtightness. We can also accommodate special process certification and traceability management according to your requirements. (The weldable plate thickness is approximately 0.1 to 2.0 mm.)

No die required: "Battery case production through welding and bending processing."

No die required: "Battery case production through welding and bending processing."

Responding to prototype and mass production needs with low cost and short delivery times. Fine dimension adjustments are also acceptable.

Our company manufactures aluminum and stainless steel battery cases using "welding and bending processing." Since no drawing dies are required, we can produce at a low cost, making it suitable for small-batch production of various types. We can meet a wide range of requirements such as dimensional accuracy, appearance, and airtightness, and we are also capable of welding thin metals of less than 0.1mm. 【Features】 ■ Bending thin plates using a press machine and welding with a laser welder, etc. ■ Eliminating the deep drawing process allows for production in a short period. ■ Capable of meeting various requirements such as dimensional accuracy and airtightness. *For more details, please refer to the materials. Feel free to contact us with any inquiries.

Proposal for a rectangular battery case that does not require a die-casting mold (Introduction of manufacturing examples)

Proposal for a rectangular battery case that does not require a die-casting mold (Introduction of manufacturing examples)

A must-see for those who find mold costs a bottleneck in battery case production! Flexible design shapes are possible with reliability equivalent to stamping processes. Numerous achievements in the aerospace industry.

At Daibei Manufacturing, we perform high-precision processing of stainless steel and aluminum cases through welding and bending operations. Thanks to our advanced welding technology, we can achieve reliability comparable to that of press processing. Since we do not use drawing molds, we reduce the costs and time required for production. We can accommodate both prototyping and mass production with short lead times. We have obtained the "JIS Q 9100 certification." We have numerous adoption records in high-quality demanding sectors such as civil aviation and special battery components for space applications. **Advantages of Welding & Bending Processing Without Using Drawing Molds:** - No molds required ⇒ Cost reduction, short lead times, and capability for small lot production such as prototyping - Easy dimension changes - High quality adopted in aerospace and defense industries *JIS Q 9100 certification obtained - We can also accommodate requests for the production of surrounding components and insulation electrocoating. *For an introduction to Daibei's technology and manufacturing examples that demonstrate the strength equivalent to press processing through bending and welding, please refer to the materials.
