How to measure the length of etch area of etcher

To calculate the suitable etching area, master the etching machine is divided into many parts: an etching machine is divided into four parts: concentrate feed part → etching area → cleaning → charging and discharging area. The feeding part of etching machine, cleaning area and boiling water cross section are fixed, and the price is determined by the length of etching. The length of etched area is determined by etching time, etching output and workpiece specification..

The length of etched area is calculated as follows:

Etching area = 1 + {total output value × (plate length + plate spacing 50 mm)} {machine width × (plate width + plate spacing 50 mm)}} construction time ÷ 60 × etching time} 0.8. Note: this formula is used to calculate the total width of the feeding material × the total width of the workpiece. Only the integer is used to calculate the total width of the workpiece, and the decimal number is removed. In order to get a closer result to the specific production and manufacturing, it is necessary to divide the result into 0.8 according to this formula. It is considered that the weekly capital transfer is time-consuming during the specific production and manufacturing.

According to the above formula, you can give an example to illustrate the test, For example, an etching factory wants to find an etching machine manufacturer to purchase a suitable etching machine for itself, but it is not clear how much the price of the etching machine is. It only knows that there are 200 * 300 mm stainless steel plates every day that must be etched and hollowed out. The production capacity is 8 hours, and 500 pieces must be produced. The thickness of stainless steel plate is 0.3 mm. It wants to buy an etching machine that can reduce the cost.

The specification of stainless steel plate is 200 * 300 mm, so it is more suitable for you to choose an etching machine with basic 700mm feed width. According to our factory's grasp, when stainless steel plate is manufactured, the corrosion depth is 0.3mm, and the etching time of hollowed out engraving is 15 minutes, and the medicine water is fast.
