Printing industry application case
At present, due to the increasing complexity of the printing process, the ever-increasing cost of printing materials, the reduction of the generation of waste products, and the improvement of quality control capabilities have become an important issue for printing companies. However, most printing companies use manual detection methods, which have many disadvantages such as slow detection speed, low detection accuracy, and inconsistent detection standards.
The company's independent research and development of color printing quality inspection system not only overcomes the shortcomings of the manual detection methods, but also has its own advantages: such as product quality standardization, detection speed, high detection accuracy, and has been successfully applied to the detection of cigarette packets, drug packages , Cosmetics packaging, various labels and other product testing, can successfully detect defects such as uneven position, knife wire, text leakage, overprint deviation, color, die-cut position, pull, ink, bronzing and other defects. In order to meet the different needs of customers, we have developed a series of inspection machine products, including Xiao Zhang Inspection Machine (DH-JP420 series), Large Inspection Machine (DH-JP1020 series), and Rewind Inspection Machine (DH- FJ series, printing quality online inspection system (DH-ZX series) and print quality inspection equipment (DH-CJ1020 series) provide a solid technical guarantee for the printing industry users to increase production efficiency and ensure product quality.

Stator Core welding is a important process for stator core assembly. We are able to use TIG, MIG, LASER weld to meet different requirement for customers. The stator core is an important part of the stator and the main component of the magnetic circuit of the motor. Different sizes of stator cores have different technological processes and application fields. For example, small-sized stator cores are usually assembled by interlocking, and the outer diameter is usually less than 200mm. Large-sized stators are assembled in different ways depending on the motor design, such as Stator core By Cleating and staor core by welding.
