How does UV marking machine achieve white marking on plastic

UV marking machine is a high-precision, high-efficiency marking equipment, which is widely used in marking the surface of plastic, glass, metal and other materials. White marking on plastic is a common application for UV marking machines. Below, we will introduce in detail the process and method of UV marking machine on plastic from the following aspects.

1. Material selection

First of all, it is necessary to choose a plastic material suitable for the UV marking machine. Generally speaking, UV marking machine is suitable for most plastic materials, such as polyethylene, polypropylene, polyvinyl chloride, etc. When choosing a material, its transparency, hardness, thickness and other factors should be considered to ensure the marking effect.

2. Equipment adjustment

Before whitening, the UV marking machine needs to be adjusted accordingly. mainly include:

1. Light source adjustment: UV marking machine adopts ultraviolet light source, and the light source intensity and irradiation time need to be adjusted according to the material thickness and marking effect.

2. Marking head adjustment: Adjust the position and pressure of the marking head according to the marking area and depth requirements.

3. Parameter setting: set the marking speed, power, repetition frequency and other parameters to ensure the marking effect.

3. Marking process

After adjusting the equipment, the marking operation can be carried out. Generally speaking, UV marking machine can achieve white marking, mainly due to its special white ink. During the marking process, the ink is irradiated with ultraviolet light, which cures quickly and forms a white mark on the plastic surface. The specific operation steps are as follows:

1. Place the plastic material on the marking table, making sure it is positioned correctly.

2. Select white ink and pour the ink into the marking head.

3. Start the device and start marking.

4. After marking, use a cleaner to remove residual ink.

4. Matters needing attention

When operating the UV marking machine, you need to pay attention to the following points:

1. Safety protection: Ultraviolet rays are harmful to the human body. It should be ensured that the eyes and skin are not directly exposed to the light source during operation.

2. Equipment maintenance: Regularly check the light source, marking head and other components of the UV marking machine to ensure the normal operation of the equipment.

3. Ink storage: White ink should be stored in a cool, dry place away from direct sunlight.

4. Plastic treatment: Before marking, the plastic surface should be cleaned to ensure that the surface is free of impurities, oil stains and other factors that affect the marking effect.

Through the above introduction, we can see that the realization of white marking on plastic by UV marking machine needs to go through multiple links such as material selection, equipment adjustment, and marking process. In actual operation, corresponding adjustments and processing should be made according to specific conditions. At the same time, pay attention to safety protection and equipment maintenance to ensure the marking effect and equipment life.
