Vacuum Roll to Roll double-sided Resistance heating Evaporation system)(Capable of double-sided aluminum plating)

Working principle of evaporation coating machine

An evaporation coating machine is a commonly used surface treatment equipment, which forms a thin film by evaporating the material and depositing it on the substrate. This thin film can change the properties of the substrate, such as increasing hardness, improving wear resistance, and improving optical transparency. The principle of the evaporation coating machine is based on the evaporation process and the condensation of materials.
The evaporation coating machine is mainly composed of an evaporation source, substrate rack, vacuum chamber, and control system. The evaporation source is the source of the evaporated material, which usually uses an electron beam or electrical damping heating to heat the material to reach the evaporation temperature. The substrate to be processed is placed on the substrate rack, usually a flat material. The vacuum chamber is a space that keeps the evaporation process in a vacuum environment, and a high vacuum state is formed by extracting the indoor air. The control system is responsible for controlling the parameters and conditions of the entire evaporation process.
The working process of the evaporation coating machine is as follows: First, the substrate to be processed is placed on the substrate rack and placed in the vacuum chamber. Subsequently, the vacuum system is started to gradually extract the gas in the vacuum chamber to reach a high vacuum state. After reaching the required vacuum degree, the evaporation source is turned on and the evaporation material is heated. Under the action of heating, the evaporation material is gradually converted into steam and diffused in the vacuum environment. The vapor is deposited on the substrate along the direction of the vacuum chamber. When the desired film thickness is reached, the evaporation source is turned off and the evaporation process is stopped. Finally, the substrate holder is taken out of the vacuum chamber to complete the entire coating process.
The principle of the evaporation coating machine is based on the evaporation and condensation process of the substance. When the material is heated to a certain temperature, its surface molecules will obtain enough energy to overcome the surface tension and thus be converted into vapor. The vapor diffuses in a high vacuum environment and is eventually deposited on the substrate. During the deposition process, the vapor molecules interact with the atoms or molecules on the surface of the substrate to form a uniform film. The vacuum environment of the evaporation coating machine is conducive to reducing the collision of gas molecules so that the evaporated material can be deposited on the substrate in a relatively high-purity form, thereby obtaining a better coating quality.
The principle of the evaporation coating machine has the following characteristics:
1. High vacuum environment: The high vacuum state in the vacuum chamber is conducive to reducing the collision of molecular gases and reducing the pollution of impurities, thereby improving the coating quality;
2. Uniform deposition: The vapor of the evaporation material diffuses in the vacuum environment, making the film deposited on the substrate uniform and dense;
3. Simple operation: The operation of the evaporation coating machine is relatively simple. You only need to set the temperature, vacuum degree, and other parameters, and control the switch of the evaporation source;
4. Wide application field: Evaporation coating technology can be applied to a variety of materials and substrates, suitable for optics, electronics, materials, and other fields.
An evaporation coating machine is a surface treatment equipment based on the principle of evaporation and condensation. It heats the evaporation material in a vacuum environment, converts it into vapor, and deposits it on the substrate to form a thin film. The evaporation coating machine has the characteristics of a high vacuum environment, uniform deposition, simple operation, and wide application. Through this thin film deposition technology, the performance of the substrate can be improved to meet the needs of thin film materials in different fields.

1. What is the Vacuum Roll to Roll Double-Sided Resistance Heating Evaporation System?

The Vacuum Roll to Roll Double-Sided Resistance Heating Evaporation System provided by Hongtian Technology Co., Ltd. is a surface treatment equipment based on vacuum evaporation technology. It forms a uniform film by evaporating the substance and depositing it on the substrate, and is widely used in optics, electronics, materials and other fields. This system adopts the resistance heating evaporation method to heat the evaporated material in a high vacuum environment, convert it into vapor and deposit it evenly on the surface of the substrate, changing the properties of the substrate, such as improving hardness, wear resistance and optical transparency.As an industry-leading high-end customized equipment provider, Hongtian Technology Co., Ltd. has been committed to intelligent manufacturing and process assurance to ensure that each device can meet customers' high requirements for quality and precision. Our Vacuum Roll to Roll Double-Sided Resistance Heating Evaporation System has an advanced technology platform and customized design capabilities, and can provide the best solutions according to the different needs of customers.The core components of the system include evaporation source, substrate holder, vacuum chamber and control system. The evaporation source heats the evaporation material to the evaporation temperature through resistance heating, and the vapor diffuses and deposits on the surface of the substrate in a vacuum environment. The substrate holder is used to support the substrate to be coated, while the vacuum chamber ensures that the entire process is carried out in a low-pressure environment to avoid interference from gas molecules and ensure uniformity and high quality of the coating.

2. How to ensure high quality and uniformity of the coating?
Hongtian Technology Co., Ltd. knows that the core advantage of the equipment is its ability to provide high-quality and uniform coatings. The coating quality and uniformity of our Vacuum Roll to Roll double-sided resistance heating evaporation system mainly come from two aspects: one is the high vacuum environment, and the other is the uniform deposition of the evaporated material.
A high vacuum environment is critical to the evaporation process. Under normal air pressure, the vapor of the evaporated material will collide with molecules in the air, resulting in poor deposition quality and many impurities. By reducing the air pressure to 0.005~0.01Pa in the vacuum chamber, we can reduce the collision of gas molecules and enable the vapor to be deposited purely on the substrate surface. This not only effectively avoids contamination, but also ensures high purity and higher film quality of the coating.
The uniform deposition of the evaporated material is the key to ensuring uniformity and consistency of the coating. The evaporation source uses 32 boat-shaped resistance heating devices to heat the evaporation material through a precise temperature control system. The heated vapor diffuses in a vacuum environment and is evenly deposited on the substrate, ensuring the consistency and uniformity of the coating thickness. This uniform coating not only improves the optical properties of the material, but also improves its wear resistance and corrosion resistance, making it more in line with high-end application requirements.
As a company committed to technological innovation, Hongtian Technology Co., Ltd. continuously optimizes the design and manufacturing process of equipment to ensure that each device can provide stable and reliable performance in complex production processes. Our Vacuum Roll to Roll double-sided resistance heating evaporation system is based on this high attention to technical details and can provide customers with excellent coating quality.
