How to ensure the stable quality of the self-adhesive car stickers during printing? Are there special quality inspection standards and processes?
1. Hardware equipment and technical guarantee
Advanced production equipment: The calender, silicon coating machine and PE coating machine introduced by HANKER not only greatly improve the production efficiency, but also lay a solid foundation for the quality control of raw materials. These equipment ensure the uniformity, flatness and surface finish of key raw materials such as PVC calendering film and release paper, providing source guarantee for the high-quality printing of self-adhesive vinyl car stickers.
High-precision printing technology: We use advanced digital printing and flexographic printing technology, combined with a high-precision color management system, which can accurately restore the colors and details in the design draft, ensuring the color consistency and image clarity of each batch of car stickers. By optimizing printing process parameters such as ink viscosity, printing pressure, drying temperature, etc., the stability of printing quality is further improved.
Environmentally friendly materials and processes: HANKER actively responds to national environmental protection policies, adopts environmentally friendly inks and glues, and advanced RTO (storage thermal oxidation) environmental protection equipment to achieve an exhaust gas treatment rate of up to 99.9%, which not only ensures the cleanliness of the production environment, but also ensures the environmental performance of self adhesive vinyl sheets, meeting the increasingly stringent international market access requirements.
2. Quality inspection standards and processes
Raw material inspection: All raw materials entering the production line, including PVC calendering film, release paper, ink, etc., must undergo strict factory inspection. Through physical property tests (such as tensile strength, tear strength), chemical property tests (such as weather resistance, chemical resistance) and environmental protection index tests, ensure that each batch of raw materials meets HANKER's high standards.
Process control: During the production process, we implement strict process quality control. Use online monitoring systems to monitor key parameters such as temperature, humidity, and pressure of the production line in real time to ensure the stable operation of printing, coating, and lamination processes. At the same time, regularly calibrate and maintain production equipment to reduce quality fluctuations caused by equipment failures.
Finished product inspection: Finished self-adhesive car stickers must undergo multiple inspection processes, including but not limited to appearance inspection (no bubbles, no scratches, uniform color), dimensional accuracy measurement, weather resistance test (simulated UV aging), wear resistance test, viscosity test, etc. Especially for products such as car stickers that have extremely high requirements for ductility, we will also conduct special tensile tests to ensure that they can maintain good fit and visual effects during application.
Customer feedback and continuous improvement: HANKER has established a complete customer feedback mechanism, regularly collects and analyzes customer feedback on the use of self-adhesive car stickers, and adjusts production processes and quality standards in a timely manner. In addition, we also actively participate in technical exchanges and cooperation within the industry, continuously introduce and digest internationally advanced quality management concepts and technologies, and promote the continuous improvement of product quality.
3. Technological innovation and product diversification
In order to meet the needs of different customers and market trends, HANKER continues to develop new products, such as car full-body stickers, bus body stickers, container surface vinyl, rough wall stickers, etc. Each product has undergone strict quality testing and optimization to ensure its best performance in specific application scenarios. Especially in the field of car film, we not only focus on aesthetics and personalized design, but also on the durability and safety of the product. By adopting special materials and technologies, the film can fit the curve of the car body tightly, effectively resist ultraviolet rays and rain erosion, while maintaining good air permeability and easy removal, truly realizing the perfect combination of beauty and practicality.
