Since its founding in 2017, AJS has continuously invested in advanced manufacturing systems to build a fully integrated production platform dedicated to Paint Protection Film (PPF) and Window Film.
In 2020, we established our own full-industry-chain production base and introduced advanced Davis casting lines and high-precision coating lines from the United States. This marked a critical step toward achieving independent core material production and complete vertical integration.
By 2021, AJS officially commenced large-scale production, becoming a true full-industry-chain PPF manufacturer — from TPU casting and coating to finished product converting and packaging.
In 2025, our expansion project was officially launched and completed with the construction of a 60,000㎡ intelligent manufacturing facility.
The new factory features:
Over 10 advanced automated production lines
International-standard precision casting systems
High-accuracy multi-layer coating technology
Intelligent process control systems
Strict environmental control and clean workshop operations
With a daily production capacity of up to 10,000 rolls, AJS ensures stable supply, consistent quality, and fast delivery for global markets.
Our production lines are engineered to guarantee:
Uniform film thickness and optical clarity
Stable adhesive performance
Superior stretchability and flexibility
Consistent self-healing and scratch resistance properties
Long-term weather and UV resistance
Every production stage is monitored under strict quality management systems to ensure that each roll meets international certification standards, including CE, RoHS, REACH, and ASTM.
