There are several production processes of fiberglass in accordance with the properties of the fiberglass material. Today we’d like to introduce some commonly used production processes for you. The main production processes, that are commonly used, are winding molding, pultrusion, compression molding and manual molding.

The process of winding molding is carried out under the cooperation of the rotating mandrel, the supporting roller and the steel strip, and the actual production of the pipe is set according to the diameter of the pipe. First, a layer of tape is wound on the rotating mandrel, and then adding glass fiber filament, resin, and outer winding yarn, and distribute it evenly on the rotating mandrel. In the process, scrape off the excess resin, then wrap a layer of polyester surface felt, and then wrap the mold from the mold. The product is removed and finally cured at a certain temperature.

The pultrusion process is designed to install a fiberglass filament onto a cream, and the fiberglass filament is pulled out by a guide roller and enters the resin container, so that each fiberglass filament is impregnated with resin.

The fiber impregnated with resin passes through the preforming mold, which is a guiding device arranged in accordance with the cross-sectional shape required for the product, releases excess resin and bubbles into the preforming mold, and then enters the mold and the glass fiber is at high temperature. Fiberglass and resin hardened and cast. Then it is pulled by the traction device and cut to the required length by the cutting device.

The molding process is to mix a certain amount of fiberglass fabric with resin, pour it into a metal matrix, apply great force using a hydraulic press, gradually harden under pressure and temperature and remove the product from the matrix.

The process of manual molding consists of applying a mixture of a resin containing a hardener on the form, and then applying a layer of fibrous fabric, cut into sections, and evenly distributing the fiber on the form with a brush, and repeatedly putting the fiber into the fabric until it is needed. The thickness is then heated and hardened under pressure.
