CA2 High-speed PVDC coating machine

In the production process of CA2 High-speed PVDC coating machine, how to control the thickness and speed of PVDC coating to meet the quality requirements of different products?

​
In the field of packaging material manufacturing, PVDC has become an important material for packaging food, medicine, daily chemicals and other products due to its excellent barrier properties. As the key equipment for uniformly coating PVDC on the substrate, the CA2 High-speed PVDC coating machine has a direct impact on the quality and performance of the product by its precise control of coating thickness and speed.
From the perspective of coating thickness control, the core of the CA2 high-speed PVDC coating machine lies in its precise coating head design and intelligent metering system. The key component of the coating head, the coating roller, is made of special materials and is processed with high precision by advanced equipment such as the Japanese MAZAK-600 horizontal machining center and the Taiwan YAWEI 3016 high-precision machining center introduced by Huitong Packaging Machinery. The surface flatness reaches extremely high standards, laying the foundation for uniform PVDC coating. The built-in high-precision metering system, developed based on the company's strong R&D capabilities, can accurately adjust the supply of PVDC according to the coating thickness requirements of different products. Taking food packaging as an example, for some products that require thin coatings to reduce costs and meet basic barrier properties, the metering system will automatically reduce the PVDC output, and cooperate with the precise gap setting between the coating roller and the substrate to achieve uniform coating of thin coatings; while for pharmaceutical packaging, due to strict requirements on barrier properties, thicker coatings are required, and the metering system increases the PVDC supply to ensure that the coating thickness meets high standards. ​
In terms of coating speed control, the CA2 high-speed PVDC coater is equipped with an intelligent transmission and control system. Its transmission system uses high-precision servo motors and high-quality transmission components. The manufacturing of these key components benefits from the company's strict quality control system. Each process is strictly inspected and the final product is tested according to international standards. The servo motor can provide stable and efficient power output, and cooperate with the precise transmission structure to achieve high-speed and stable operation of the equipment. The advanced sensors and control systems equipped with the equipment are like the "nerve center" of the equipment, monitoring the coating speed in real time. When producing different types of products with differentiated requirements for coating speed, the operator only needs to enter the corresponding parameters in the control system, and the control system will respond quickly and accurately control the coating speed by adjusting the servo motor speed. For example, when mass-producing ordinary food packaging materials, the equipment can quickly increase the speed, greatly improving production efficiency while ensuring coating quality; while producing electronic component packaging materials with extremely high coating accuracy requirements, the speed can be reduced to ensure uniform and flawless coating. ​
In order to meet the diverse quality requirements of different products, the CA2 high-speed PVDC coater has a high degree of flexibility and adaptability. The company adheres to the mission of innovation and facing the world, and continuously optimizes and upgrades the equipment so that its control system can realize the free combination and fine adjustment of multiple parameters. Whether it is pet food packaging with specific requirements for coating thickness and speed, or clothing packaging that focuses on the combination of appearance and performance, the equipment can meet the needs by adjusting parameters. For example, pet food packaging may need to increase the coating speed to adapt to large-scale production while ensuring a certain coating thickness to maintain good barrier properties; while clothing packaging may pay more attention to the uniformity and aesthetics of the coating, the equipment can appropriately reduce the speed to ensure that PVDC is fully and evenly coated. ​
The CA2 high-speed PVDC coater also has a complete monitoring and feedback mechanism. Various sensors distributed on the equipment can monitor key parameters such as thickness, speed, temperature, and pressure during the coating process in real time. Once a parameter abnormality occurs, the sensor will immediately feedback the signal to the control system, and the control system will automatically adjust it according to the preset program. If a coating thickness deviation is detected, the system will promptly adjust the PVDC supply of the metering system and the pressure of the coating roller; if speed fluctuations are found, the servo motor speed will be quickly adjusted to ensure the stability of the coating quality. This intelligent monitoring and feedback mechanism not only reduces manual intervention, but also greatly reduces quality problems caused by human factors, and improves the automation level of the production process. ​
With its excellent performance in controlling coating thickness and speed, as well as overall high performance and reliability, the CA2 high-speed PVDC coater has won wide recognition in the market. The equipment produced by Jiangyin Huitong Packaging Machinery Co., Ltd. is exported to many countries including Canada, Australia, South Korea, Russia, Thailand, Vietnam, etc. The export volume accounts for a high proportion of the total output, and has established a good reputation in both domestic and foreign markets.
