[0002] Fiberglass composites are made from glass fiber and a highly heat-resistant composite material. They contain no harmful asbestos. They offer superior mechanical and dielectric properties, excellent heat and moisture resistance, and excellent processability. When used as a soft-cover base, they can be covered with fabric or leather for decorative purposes, creating beautiful wall and ceiling surfaces. They offer sound absorption, insulation, heat insulation, environmental friendliness, and flame retardancy.

[0003] When glass fiber composite material support plates are used, a forming machine is required for extrusion molding to bond the glass fiber base layer with the outer soft package material.

However, since it is difficult to adjust the pressure when extruding glass fiber composite plates of different thicknesses, it is difficult to expel bubbles during the extrusion molding of glass fiber composite plates of different thicknesses due to pressure, thereby reducing the density of the glass fiber composite plates.

[0004] Based on this, a glass fiber composite material forming machine is designed, which can specifically adjust the pressure and preheat the glass fiber composite board before extrusion to increase the density of the glass fiber composite board. Utility Model Content
