Vacuum pump:

Function

• In the process of making rubber heads: During the rubber head making process, the vacuum pump can remove bubbles from the rubber head material. For example, when using materials such as silicone to make rubber heads, vacuuming can make the material denser, avoiding the uneven surface of the rubber head or holes caused by the presence of bubbles, thereby affecting the printing effect.

• In the process of adjusting ink: During the ink adjustment process, the vacuum pump can remove the air in the ink. Because bubbles in the ink can cause pinhole defects or incomplete patterns during printing, vacuuming can make the ink more uniform and delicate, which helps to improve the printing quality.

Principle

• The vacuum pump operates through a vacuum pump to reduce the air pressure in the container. When the air pressure in the container is lower than the external atmospheric pressure, the gas molecules in the rubber head material or ink escape from the material or ink under the action of the pressure difference and are extracted, thereby achieving the purpose of removing bubbles.

Selection points

• Vacuum degree: Generally, a high vacuum degree is required, usually below -0.09MPa, so that bubbles can be removed more effectively.

• Vacuum speed: Select according to the production scale. If the processing volume of the rubber head or ink is large, a vacuum pump with a fast vacuum speed should be selected to improve work efficiency.

• Vacuum chamber size: It should match the processing volume of the rubber head or ink to ensure that it can accommodate the material or ink to be processed.

Product Description

      In The process of making rubber pad, There full of air between silicon rubber mixxing liquid. In order to remove the air, use RM-20BV Vacuum machine to reach the result.
This process will increase the life of rubber pad.

Application︰

Viscous liquid vacuum treatment;
The batching process of printing plastic head vacuum processing.
