Melamine Two Step Impregnation Line

Melamine Two-Step Impregnation Line is used to produce melamine-impregnated decorative paper through a first impregnation stage and a second coating stage, with front and rear drying ovens for independent drying and pre-curing control.

This process allows precise adjustment of resin pickup and surface film formation, making it suitable for stable mass production of impregnated papers forMFC and Shuttering Plywood.

Customization

Line configuration, including oven zone number and unit requirements, can be recommended or customized based on base paper basis weight and dimensions, production capacity targets, and finished paper requirements.
