New Products of Weifang Donghang Precision Machinery Co., Ltd.

Located in Weifang Hi-tech Industrial Development Zone, Weifang Donghang Precision Machinery Co., Ltd. is a high-tech enterprise integrating research and development, production, sales and after-sales service of printing and postpress equipment. It is adhering to the business philosophy of “customer first, improvement and innovation”. , was the National Printing Machinery Quality Supervision and Inspection Center as one of the ten outstanding small offset printing companies recommended by the country. In order to welcome the All In Print Exhibition in June this year, China Eastern launched the following products:

DH452 six-color four-color/DH252 six-color two-color business printing machine
The two presses feature a double-diameter impression cylinder structure that is more suitable for printing thick paper. On this basis, the DH452 has also increased the paper flattening mechanism at the delivery section to further level up the printing paper. The overall thickening of the cast iron base and the 35mm thick cast iron wall plate provide a reliable basis for the high-speed and high-efficiency operation of the complete machine.

DH452 and DH252 have many advantages: For example, the roller side pull gauge on both sides can be precisely adjusted during the printing process; the centering and hem type transfer mechanism ensures the smooth transfer and transfer of paper at high speed; automatic pneumatic clutch pressure control The pressure-increasing action is rapid and smooth; the continuous water-alcohol dampening mechanism with a bridge roller makes the ink and ink balance faster and the dots more clearly.

DH66 Senior Open Heavy Commercial Printing Machine
DH66 senior open offset press is the ideal model for business packaging printing. The whole machine adopts high-strength cast iron wall plate and high-precision helical gear drive, which is firm and durable, and the performance is stable. The high-speed paper feeding separation head increases the reliability of paper feeding; the high-precision side and front gauge adjustment can realize the printing position adjustment without stopping the machine. Reasonable ink roller arrangement ensures true color reproduction; automatic multi-point recirculation oil system ensures long-term use of the machine.

In addition, high-strength cast iron is used for the cylinders, wall plates, and bases of this type of commercial printing press, while Federer's continuous paper feeding, compact gas distribution mechanism, and forced air switching timing are reflected in high-speed paper feeding. Its great power. At the same time, its integrated adjustable front gauge can also be adjusted during mechanical operation. The eccentric tilting type feeding mechanism and the fully closed embossing paper catching cam make the picking more reliable and the overprinting more accurate.

DH series flexo printing machine
The DH series flexographic printing machine with modular design can be freely selected and freely combined according to user needs. The electronic correcting system, unwinding brake system, still image detection system and post-correction system of the DH series flexographic printing press adopt the original configuration imported from the United States, which can fully meet the needs of customers for printing high-quality prints.

The performance advantages of DH series flexo presses are as follows:

1. The main motor adopts imported inverter stepless speed regulation; automatically records the length of printing, the number of printed sheets, and the set length automatically stops and alarms.

2. Paper feeding and paper collection are controlled by magnetic powder brake and clutch; ceramic mesh ink roller is used, which is wear-resistant, corrosion-resistant and has long service life.

3. The printing unit adopts 360-degree circumferential adjustment. Each printing unit can be entered into or out of print independently; the color-coded photoelectric sensor technology is used to automatically match the colors of the standard, the overlay accuracy is high, and the pre-press preparation time is short.

4. Optimize the ink roller configuration according to the modern printing process, effectively preventing the occurrence of ink bars and ghosts, and greatly improving the printing quality. The amount of ink supplied is automatically adjusted according to the printing speed. The ink roller is automatically disengaged and rotated at a low speed during parking to prevent the ink from drying.

5. Printing pressure stabilization device can be used for high-speed printing. After replacing the printing plate cylinder, there is no need to re-adjust the printing pressure; each printing unit is equipped with a set of infrared drying device; the paper-lifting and paper collection adopts gas-lifting mandrel clamping Device.

6. The paper roll feeding, printing, coating oil, round press die cutting, discharging and rewinding are completed at one time; the machine failure is automatically displayed on the computer screen, which is suitable for printing multiple varieties of different batches of notes, labels, etc.

With the launch of this new series of products, Weifang Eastern Airlines, with its goal of creating a brand and achieving customer satisfaction, will surely shine!
