PULTRUSION PROCESS GLASS PLATE

PULTRUSION PROCESS GLASS PLATE

The pultrusion process is a continuous production method of composite material profiles. It is to impregnate the non-twisted glass fiber roving and other continuous reinforcement materials on the creel with resin, and then form by maintaining a certain cross-sectional shape. Mold, and make it solidify in the mold and continuously exit the mold under the pulling force of traction machinery, thus forming an automatic production process of pultrusion products.
