Batch coding machine
 |
Batch printing machines, marking machines, date printing machines are used in the following applications:
- Pharmaceutical & other packaging industries to print Batch No.., Mfg. Date., Exp. Date., Retail Price etc.. on their plain or laminated & varnished Labels/Cartons, Polypack Bags, Pouches, tin Bottoms, Cotton Bags,bottles, jars or any solid surfaces etc...
- adding special information at the time of actual packing.
- adding price change or special offer on existing labels/cartons.
Types of machine
Batch coding machines are mainly categorized in following two categories -
- contact coding type
- Non contact coding type
They are further sub categorized into following types depending upon the type of their working.
- Automatic
Once set, works automatically with the operator only having to look after its working and settings. Feeding, printing, collecting operation are done automatically, however these features vary in different makes of machines.
Automatic machine working is shown in this video.

- semi automatic
The machine works on its own but the feeding and collecting has to be done by hand.
A Semi automatic machine is seen working in this video.

- hand operated or manual
Feeding as well as the machine are operated manually. They are suitable for small production and can be portable.

- Online
These machine works automatically inline with other machines or they can be of continuous type with feeding by other machine, by hand or other feeding mechanism, but are integrated or attached in line with other online machines.

Contact coding type
These machines prints/mark on products by contacting the product surface. They mostly use some letters made up of metal or rubber and ink media like liquid ink or a ribbon or solid ink etc to make an impression. The letters are made offset, so while printing they give mirror image and straight print is obtained.

Non contact coding type
These machine do not comes in contact in any way while printing or marking on products. Normally these machine uses beams/spray for marking. These beams may be of laser, or the spray of ink, the most important factor is that theproduct or machine should be moving at constant speed.
The moving product are sensed by a sensor & give a signal to the machine which responds immediately with the printing. These machine also work as online machines. A few machines in this category are Inkjet printer, Laser printer, industrial Inkjet coding machine, laser marking systems.
