How should we debur aluminium strips?

The most tricky problem in aluminium tape production proves to be deburring. Here we introduce three methods for deburring of the aluminium flat strip.

1. Deburring by hot explosion

This method is also called thermal deburring or explosion deburring of thin aluminium strips. By introducing some volatile gases into an equipment furnace in some media and conditions, the gas explodes instantaneously, and the burrs are removed by dissolving the energy generated by the explosion. Disadvantages of this method include high cost of equipment (millions of prices), high technical requirements, low efficiency and side effects (rust, deformation of the deburred aluminium tape).


2. Chemical deburring

Chemical deburring of the aluminium flat strip is based on the principle of electrochemical reaction, the deburring process is automatically and selectively completed. This method is suitable for internal burrs which are difficult to remove, and for small burrs of pump body, valve body and other products (thickness less than 7 wires).

3. Electrolytic deburring

An electrochemical machining method for removing burrs in aluminium flat strip by electrolysis is presented. Electrolytic deburring is suitable for removing burrs in concealed parts of  aluminium strips, such as cross holes or parts with complex shapes. It has high production efficiency. The deburring time usually takes only a few seconds to tens of seconds.
