How to choose a suitable screen printing machine

Fully automatic screen printing machine technology is now becoming more and more mature, and more and more products are available for purchase in the market. Nowadays, the fully automatic screen printing machines on the market can be mainly divided into two types: sheet automatic screen printing machines and roll automatic screen printing machines. Some users also choose semi-automatic screen printing machines and hand printing stations. This time I will tell you about roll-to-roll screen printing. The inside story of the three major industries of the machine.

1. The structure is unreasonable. The distinctive feature of the roll-to-roll fully automatic screen printing machine is roll-to-roll printing. Regardless of the applicability, it is not based on actual industry applications. 例えば, the front-end feeding system and induction box are a very simple structure. Some manufacturers have been using it for several years. None of them have been updated. The structure of the machine’s beam, guide column and two columns is easily loose, causing inaccurate color registration. It has been consistent for more than ten years and I don’t know how to update it.

2. The oven temperature is uneven. Roll-to-roll fully automatic screen printing machines generally use return-type ovens due to their small floor space. They are heated on one side. The design of one-side heating can cause problems with different temperatures on the left and right sides of the material, especially when the temperature is too high. , the temperature difference is even greater. At 180 度, the temperature difference between the left and right sides of the material can reach about 40 度, which can easily cause uneven shrinkage and lead to material deformation and inaccurate color registration. 一般的に, if the material deforms during proofing, it will cause If the color registration is inaccurate, the customer will be advised to change the material for testing.

3. Color registration accuracy. There are several aspects to control the color registration accuracy of a roll-to-roll automatic screen printing machine. One is the balance adjustment of the puller roller and the stability of the puller servo and reducer. The other is the compactness of the structure when installing the mesh arm, and the compactness of the machine head when installing it. Compactness, thirdly, the balance of the vacuum platform, the coordination of the beam and guide pillars, 等. These are the keys to the accuracy of color registration.

4. Energy saving of the machine. The energy saving aspect of the roll-to-roll fully automatic screen printing machine mainly lies in the design of the oven. For ovens with the same power, temperature loss and uniformity or heating method control are all issues that the machine manufacturer must consider.
