1. The heat transfer power of glass is low, the insulation of the surface of the work-piece is done well, and the service life of the mold is guaranteed.

2. The smooth performance is three times higher than graphite, the production rate and width increase accordingly, and then the scale of the products produced by the coiling machine can be expanded.

3. The glass smoothing agent is chemically stable and will not cause shortcomings in the arrangement.

4. The concentration of the glass can be adjusted freely to obtain different physical functions to meet the needs of products that roll different materials.

5. Clean and environmentally friendly, with little side effects on the environment.
