Technological Innovation
The development and innovation of rubber technology have been the soul of our company. Starting from solid cushion printing blankets, the company successfully developed air cushion printing blankets, evolving from initial chemical foaming techniques to advanced microsphere foaming technology. These advancements solidified Baochun’s position as a domestic pioneer in printing blanket development. In its second decade after establishment, UV printing grew rapidly due to its fast drying speed and environmental benefits. Our company swiftly responded by developing UV printing blankets, filling the gap in domestically produced UV-specific products. Now entering its third decade, Baochun are facing an evolving printing industrial challenge marked by overcapacity across supply chains and heightened quality demands. As always, we will commit to technological innovation to meet today’s industry upgrades.
Main Equipment

High-precision grinding equipment ensures flatness and accuracy of the rubber blanket surface.

Drum Vulcanizer
Advanced vulcanization equipment ensures rubber blanket elasticity and durability

Calender
Precision coating equipment for uniform coating thickness control
Key Manufacturing Processes
Rubber Mixing
Premium Imported Rubber
Microsphere foaming
We employ latest microsphere foaming technology to create superior air cushion layers in every printing blanket. This ensures exceptional elasticity and precise dot reproduction capability for consistent print quality.
Fine grinding
As the final yet pivotal stage, precision grinding guarantees flawless ink transfer. Equipped with Swiss-engineered high-precision grinders and three decades of proprietary grinding expertise, we deliver blankets with super ink transfer performance.
Vulcanization Technology
Vulcanization is a critical step in blanket manufacturing. Using our flat-belt drum vulcanization system, we achieve precise curing under optimized temperature and pressure, ensuring dimensional stability and long-term durability.
Calendering Technology
In the production of rubber blankets, we use calendering technology. Our process requires no toluene, delivering both superior quality and environmental benefits.
