Lab Vacuum Sealing Machine For Preparing Pouch Cell 


It mainly used for the first vacuum sealing of punch/polymer battery (soft-pack)lithium cell after injected and final sealing.

1)It can suitable for different specifications of battery,easily to adjust,only do the speed regulation(or change)clamp and adjust(or change)the related sealing head ok.

 2)There are battery pressing platen within the upper cabinet,to press the battery tightly and make the welding effrect better.

3)The sealing-head is made of copper materials, heat transfer effect is good save power consumption,improve work efficiency.

 4)The head temperature can set through the thermostat panel button control, the current value of the temperature and the set point can be through its LCD screen display, intuitive and easy operation.

Working principle

This equipment is used the tilt(flip type)to form a closed cavity,then pump the air in the cavity to form -90KP of in a negative pressure state,so that make the air within batteries core excluded.

Platen of the upper chamber use the cylinder pressing materials,and then trough sealing head using the heat conduction effect acting on a lithium battery packaging material(aluminium-laminated film),and heated close to the molten state softened and fused together.
