Step into the production workshop of Kunshan Yingliyue Electronics, and you’ll witness a remarkable scene: inside a high-vacuum chamber, an invisible “magic” is quietly unfolding. Ordinary metal, plastic, or ceramic components, through a series of physical transformations, “grow” a uniform, dense, a
We provide professional one-stop surface treatment services including PVD vacuum coating, sandblasting, precision polishing, and laser engraving. We focus on metal and plastic parts such as aluminum alloy, stainless steel, and engineering plastics, widely used in 3C electronics, automotive inter
Core Answer: Clarifies that PVD coating can simultaneously meet environmental compliance and performance standards. Environmental Advantages: Briefly describe the core environmental characteristics of the PVD process. Performance: Summarize the key performance standards required for mobile phone components. Customer Assurance: Supplementary certification and service support.
PVD (Physical Vapor Deposition) and CVD (Chemical Vapor Deposition) are two major thin-film coating technologies. PVD vaporizes materials through physical means (e.g., heating or sputtering), resulting in strong adhesion but slower deposition rates. CVD forms coatings via chemical reactions, off
As a new polishing process, plasma polishing is a trend in stainless steel polishing. If we can make good use of plasma polishing will save us a lot of time and costs.

To further improve the stability and consistency of coating, PVD coating and metal surface treatment processes, Kunshan Yingliyue Electronic Co., Ltd. continues to benchmark its internal process management against AIAG CQI special process requirements. By focusing on Customer Specific Requirements (CSR), process audits, on-site control, pyrometry management, spray booth environment, pretreatment cleaning and curing control, the company is continuously strengthening its quality management capabilities and providing customers with more stable, reliable and consistent surface treatment solutions.
The AIAG CQI series is widely recognized in the automotive and high-end manufacturing supply chain as an important methodology for special process management. Among them, CQI-12 Coating System Assessment (CSA) focuses on coating, pretreatment, curing, equipment calibration, job audits and process error prevention. It emphasizes defect prevention, process stability, continuous improvement and the reduction of quality risks throughout the supply chain. For coating and surface treatment companies, CQI-12 is not merely a checklist, but a systematic management approach covering quality planning, shop-floor execution, process parameters, personnel competence, equipment control and product verification.
In daily production management, Kunshan Yingliyue Electronic Co., Ltd. remains customer-oriented and integrates CSR requirements into its internal quality management system. The company continues to improve fundamental quality documents and management tools, including APQP, PFMEA, control plans, work instructions, inspection standards, process records and traceability management. By identifying, monitoring and verifying key process parameters, the company further strengthens closed-loop quality control from incoming materials, pretreatment, cleaning, coating/PVD, curing and inspection to final delivery.
In the pretreatment and cleaning stages, the company focuses on key control points such as degreasing, rinsing, RO water rinsing and drying. Parameters including time, temperature, concentration, liquid level, pressure, conductivity, water quality and drying conditions are carefully managed to reduce risks related to surface residue, insufficient cleaning, incomplete drying, adhesion defects, appearance issues and corrosion resistance performance.
In the coating and surface treatment stages, the company continues to enhance spray booth environment control and equipment condition management. Key factors such as temperature, humidity, air velocity/airflow, pressure differential, cleanliness, atomizing pressure, coating flow rate, spraying program, loading method and product appearance consistency are strictly controlled to ensure that color, film thickness, appearance, adhesion and durability meet customer requirements.
In pyrometry and curing management, the company attaches importance to the control of thermocouples, temperature control equipment, ovens/furnaces temperature uniformity and temperature records. Equipment calibration, inspection and verification activities are continuously standardized to ensure that the curing process remains under control and to reduce coating performance variation caused by temperature deviation.
Quality is not created by final inspection alone; it must be designed, prevented and controlled throughout every process step. Kunshan Yingliyue Electronic Co., Ltd. will continue to use CQI-based special process management as an important guideline to strengthen personnel competence, equipment capability, process capability and on-site execution, promoting its quality system from result-based inspection to process-based prevention.
Looking ahead, the company will continue to uphold the quality philosophy of stable quality, continuous improvement, customer orientation and controlled processes. With stricter process management, stronger quality traceability and higher delivery standards, Kunshan Yingliyue Electronic Co., Ltd. is committed to providing professional, efficient and reliable surface treatment services for customers in 3C electronics, smart wearable devices, automotive components, high-end hardware and other precision manufacturing fields.
