Li Cell Aluminum Shell

As the protective shell of the power battery, the power battery shell is also the key factor to determine the quality of the power battery. The aluminum shell material of the power battery has the advantages of low density, soft material, easy to stretch the whole battery shell and so on, and has been used by many enterprises for power battery packaging.  Aluminum alloy is much less dense than traditional stainless steel packaging materials.  In order to increase the range, new energy electric cars need a lot of lithium battery combination module, each module is made up by a number of battery box, in this way, the quality of each battery box size had a great influence on the quality of the whole battery module, in order to reduce battery quality, adopt aluminum alloy material to make the power battery shell is the inevitable choice.  

1,Among nonmetallic materials, aluminum has excellent aging resistance. The anti-aging performance test shows that the maximum aging thickness of the surface is less than 50μm for 20 years in different places and different climatic zones. The minimum thickness of most boxes is 5mm, less than 1% of the box thickness, so there is no significant impact on the mechanical properties of the box.

2,The shell of lithium battery is made of high-quality aluminum, which is extruded and formed with explosion-proof, high temperature resistance, corrosion resistance and other characteristics. The surface treatment performance is good, the chemical performance is stable, the non-magnetic, and it can be recycled.

Mold advantages:  

Manipulator adopts German Siemens system.  

Single row feeding, using positive pulling mechanism, including tensile convex and concave die and attached fixing device, guiding device, material jacking device, in addition, each station can be installed separately edge holder device, convenient to change the product model.  

Each station separately adjust unloading, most parts are applicable to the same type and model.  

Mold stand each station can independently fine-tune the mold height of each process, debugging mold is very convenient.  

Each station of the mold has a circulation system, a water circulation channel inside the mold and related accessories.
