Production Technology and Development and Application of Fiberglass Tube

The production process of glass fiber tube

There are three main types of glass fiber tube production processes: reciprocating filament winding process, continuous filament winding process and centrifugal casting process.

Reciprocating filament winding process (belonging to the fixed-length method): In this process, the dipping tank reciprocates with the rotating mandrel, and the long fiber glass filaments are placed at a certain oblique angle relative to the mandrel axis, and the auxiliary angle (ie. The winding angle) is controlled by the ratio of the moving speed of the dipping tank to the rotational speed of the mandrel, and the translational movement of the dipping tank is controlled by computerized electromechanical control. The number of winding layers is gradually increased until the designed wall thickness is reached. After the winding is completed, the resin in the article is substantially cured. After curing, the mandrel is removed from the fiberglass pipe.
