Comparison between CIJ jet printer and DOD printer application of printing technology nowadays, the application of marking technology is gradually going deep into every corner, especially in industry. The application scope is becoming wider and wider, and the complexity of application is greatly increased, making marking an indispensable part of the production of (2) friction, peak value and load industries. The production of plastic extruded materials such as plastic pipe, profile, aluminum (steel) plastic composite pipe is no exception. The main reasons for plastic extrusion material manufacturers to mark their products are as follows:

1) it is conducive to product identification. By marking special marks, brand names and trademark patterns on the products, the products can stand out in the competition and improve the brand awareness

2) the need for product tracking records. The batch number, shift or production date of the product are directly printed on the product, so that each product has good traceability, which greatly facilitates the quality management of the enterprise and the regional management of the product

3) prevent counterfeiting. Manufacturers can often prevent and suppress counterfeiting through product identification. The application of new technologies enables those legitimate manufacturers to always be ahead of counterfeiters

4) increase the added value of the product. Marking the trademark or the name of the manufacturer on the plastic pipe means a commitment. Consumers usually think that it is the product of an enterprise with relatively perfect quality tracking and responsible for product quality

selection of inkjet printer

according to the difference of the working principle of inkjet printer, the inkjet printer can be divided into the following two categories:

1) continue ink jet printer (CIJ type for short)

its working principle: the ink is continuously ejected from a single nozzle through pressure. After crystal oscillation, more attention should be paid to the fracture to form ink spots; After charging and high-voltage deflection, the ink dots are scanned into words on the surface of moving objects

2) drop on demand inkjet printer (DOD for short)

its working principle: the nozzle is composed of multiple high-precision valves. When spraying words, the valve corresponding to the font opens and closes quickly. The ink is sprayed out by internal constant pressure, forming characters or graphics on the moving surface

performance comparison of two principle inkjet printers:

item CIJ inkjet printer DOD inkjet printer character height 0.06mm-15mm 2.5mm-64mm inkjet printing rate inkjet printing 5*5 dot matrix is very fast, and the speed becomes slow when inkjet printing Chinese, graphics and 16 dot matrix characters. The printing speed is not affected by the font lattice, and the fastest speed with a computer can reach 120m/min. When the ink concentration machine is running, the ink is recycled, and the ink concentration is unstable. When the machine is running, the ink is not recycled, and the ink concentration is consistent. Diluent needs to be added to the operation cost, and the diluent volatilizes continuously, resulting in waste. There is no need to add diluent, and the operation cost is lower than that of CIJ. The ink supply system ink recovery system is easy to suck dust and moisture into the machine, affecting the normal operation of the machine. The ink does not need to be recycled, and the ink supply system is well sealed to avoid ink pollution. The failure rate ink dots need to be precisely controlled by crystal oscillation, charging, high-voltage deflection, etc., with high failure rate. The ink is directly ejected, with its own pressure pump, less precision parts and low failure rate. The operation control system is complex and requires precise adjustment of parameters to ensure normal operation. The control system is simple and reliable, easy to operate and easy to maintain. Environmental impact during ink circulation, a large number of organic solvents volatilize and smell bad, polluting the environment. The ink does not need to be recycled, has no pungent smell, and has little impact on the environment. The air source is supplied by the external air source. It has high requirements for pressure and cleanliness. The quality of the air source directly affects the service life of the machine. Equipped with low-pressure air supply system, the air supply pressure is stable and the quality is clean to ensure the normal operation of the machine. Sealed gear pump inkjet printer requires ventilation and heat dissipation when the motor is running at high speed. Dust and moisture are easy to enter the machine due to unsealed. There are no high-power devices in the machine, so there is no need for heat dissipation during operation. The equipment system is well sealed and is not affected by the working environment. Maintenance: the gear pump is easy to wear and cannot be repaired, so it can only be replaced. If the maintenance is standard, once the original height is changed. There are no wearing parts in the machine, and the maintenance cost is greatly reduced compared with the CIJ inkjet printer. (end)
