DankoVAC evaporation vacuum plating machine: How to accurately control the metal texture and glossiness of car logos?

1. Process principle and core technology
The process principle of DankoVAC evaporation vacuum plating machine is based on physical vapor deposition (PVD) technology, which is a process of heating solid metal source materials to an evaporation state in a vacuum environment, and then depositing the evaporated metal atoms or molecules on the surface of the substrate by physical means (such as electric field acceleration). Its core technology lies in creating and maintaining a highly pure vacuum environment, and precisely controlling the temperature and evaporation rate of the evaporation source. This technology not only ensures the purity and uniformity of the coating, but also forms a strong bond between the coating and the substrate, thus giving the car logo a lasting and charming metallic texture and gloss.

2. Key factors for precise control
Vacuum control:
Precise control of vacuum is the basis for DankoVAC evaporation vacuum plating machine to achieve high-quality coating. The high vacuum environment reduces the interference of gas molecules on the evaporated metal atoms, ensuring the purity and smoothness of the coating. DankoVAC uses advanced vacuum pump systems and sealing technology to achieve and maintain the required vacuum in a very short time, providing stable environmental conditions for subsequent evaporation and deposition processes.
Evaporation source temperature and rate control:
The temperature and evaporation rate of the evaporation source are key factors in determining the thickness and quality of the coating. The DankoVAC evaporation vacuum plating machine is equipped with a high-precision temperature control system and an evaporation rate adjustment mechanism, which can accurately set and maintain the temperature of the evaporation source according to specific process requirements, thereby ensuring that the metal wire is uniformly melted and evaporated at a stable evaporation rate. This precise control not only ensures the uniformity of the coating, but also allows the thickness of the coating to be adjusted over a wide range to meet the personalized needs of different car logos for metal texture and gloss.
Deposition process optimization:
The optimization of the deposition process is an important part of achieving high-quality coatings. The DankoVAC evaporation vacuum plating machine uses the electric or magnetic field effect to guide the evaporated metal atoms or molecules to the surface of the substrate, and achieves uniform deposition and densification of the coating by adjusting deposition parameters (such as electric field strength, deposition time, substrate temperature, etc.). The equipment also uses advanced deposition chamber design and airflow control technology to effectively reduce defects and impurities in the coating, further improving the quality and appearance of the coating. By continuously optimizing the deposition process, DankoVAC can ensure that the car logo presents a delicate, bright and lasting metal texture and gloss.

3. Quality inspection and feedback mechanism
In order to ensure that the metal texture and gloss of the car logo meet the design requirements, the DankoVAC evaporation vacuum plating machine is equipped with a complete quality inspection and feedback mechanism. This mechanism covers all aspects from raw material inspection to finished product inspection, including coating thickness, hardness, corrosion resistance, adhesion and appearance quality. By adopting advanced testing equipment and means (such as scanning electron microscope, X-ray diffractometer, etc.), DankoVAC can accurately measure the performance indicators of the coating and compare them with the preset quality standards. Once a deviation or non-conformity is found, the system will immediately issue an alarm and feedback to the production control center so that adjustment measures can be taken in time. This rapid response and continuous improvement of the quality inspection and feedback mechanism ensures that the DankoVAC evaporation vacuum plating machine can continuously and stably produce high-quality car logo coating products.
