Quality appraisal of printing equipment

For the entire printing industry, the composition of printing machinery is relatively complex, but it itself plays an important impact on the printing industry. In order to better ensure the quality of printing machinery and avoid corresponding quality problems, research on the quality of printing machinery is gradually increasing. It is very important to detect and identify the quality of printing machinery.

In the process of production, enterprises also need to pay more attention to the repair and maintenance of printing machinery, which will play a certain role in promoting the production of printing machinery and the development of the printing industry. Zhongke Testing provides printing equipment quality appraisal services.

printing equipment quality appraisal can be analyzed from the following aspects:
machine performance: evaluate the speed, accuracy, stability and other performance indicators of the equipment to check whether it can meet the requirements of different printing tasks.
printing effect: Observe the printing quality of the printing equipment, including image clarity, color accuracy, ink uniformity, etc.
Durability: Check the structure and durability of components of the equipment, including service life, replacement and maintenance costs of wearing parts, etc.
Reliability: Evaluate the failure rate and reliability of the equipment, including the convenience of fault diagnosis and repair, to ensure long-term stable operation of the equipment. The quality appraisal of
printing equipment can be evaluated from aspects such as machine performance, printing effect, durability and reliability. Therefore, all factors need to be fully considered, and in practical applications, customized analysis needs to be conducted based on specific circumstances.

In order to expand production, a printing factory purchased two new printing machines, thinking it was just in time to receive a batch of new contract orders. However, during the process of being put into use, one of the printing machines suffered from printing ink blur, which affected the quality of the finished product. The printing factory and the equipment factory put forward their opinions, and the other party agreed to send special personnel to maintain it. Not only that, but before it arrived, another printing press exploded, causing serious injuries to an operator. Subsequently, the public security agency intervened and entrusted an appraisal agency to appraise the quality of the printing press. The
expert team arrived at the site for investigation. When entering the workshop where the printing press was located, experts suggested that the environment in the workshop was too humid, which would affect the work of the printing press. Immediately, the team inspected and studied the printing machine, and finally concluded that there was no problem with the quality of the printing machine itself, and all indicators were in compliance with national standards. So back to the environmental issue. After verifying the design, when the printing press is working, if the surrounding environment is too humid, the moisture will be directly decomposed into oxygen and hydrogen, resulting in a decrease in the insulation capacity of the contact head. This has also been confirmed through testing. What is more serious is that due to poor contact, severe arcing occurs, resulting in explosion.
The poor printing quality of another printing press is also causally related to this reason.
To sum up, the workshop where the printing press is located is temporarily freed for use, and the environment is too humid, which affects the work of the printing press and even causes it to explode.
