Chemical etching machine for glass products

To achieve mass production of slimming LCD glass substrates, there are 2 representative methods: “mechanical grinding” and “chemical etching”.

 

In recent days, chemical etching has been the mainly adopted method for its superiority in processing each glass substrate with a short takt time.

 

Among several different methods to perform chemical etching, in order to handle those LCD glass substrates growing larger in size, NSC Engineering chooses to design & fabricate single substrate chemical etching machines on which the glass substrates are conveyed in a horizontal lying position.

Features of ultra-thin glass slimming machine “NX”

Features of ultra-thin glass slimming machine NX

The machine “NX” carries forward the glass substrates which are laid flat on the conveyor and at the same time sprays etchant (strong acid) onto these glass substrates. In this way, workpieces can be conveyed and slimmed simultaneously.

 

Total thickness of 0.05 mm or less can be realized after finishing the process.

 
Uses

Mobile devices which demand thinner and lighter glass substrates.

Example

1. Smart phone
2. PC
3. Cover glass, etc.

The main point in fabricating an etching machine

For etching machines in general, given that strong acid is used as etchant, in most cases the machines should be made of plastic resin which is chemical resistant.

 

Resins can be processed by any equipment with high accuracy, however, resin welding techniques, which greatly affect the perfection of an etching machine, are not easy to be acquired.
