There are three main types of GFRP grille production process: reciprocating fiber winding process, continuous fiber winding process and centrifugal casting process. Reciprocating filament winding process (n) : in this process, the leaching glue tank with rotating mandrel for reciprocating motion, the long fiber glass with a certain Angle relative to the mandrel axial auxiliary, auxiliary Angle (that is, the winding Angle) baptism glue tank movement speed and the ratio of the core mold speed control, soak glue tank translational motion by computerized machine electric control. The number of winding layers increases gradually until the wall thickness of the design is achieved. After winding, the resin in the products basically solidified. After curing, the core die is removed from the glass steel tube.
Continuous filament winding process (belonging to the continuous process) : the process is made of the pipe in motion through a feed station which supplies the resin pre-impregnated roving, short-cut fiberglass fiber and resin sand mixture, and the pipe is made in the continuous advance of the core mold.
Centrifugal pouring process (n) : in this process, using glass fiber reinforced materials and sand, feeding on the bearing steel in the mould, injection plus unsaturated resin catalyst in die end, make its dipping reinforced material, under the effect of centrifugal force, the resin exchange fiber and filler in the air, so as to create a nonporous compact composite material, the effect of tube wall due to centrifugal force to form a smooth, bright and clean surface layer of rich resin, steel tubes under high temperature curing. The pipe made in this way is also called glass reinforced plastic sand pipe.
At present, there are more reciprocating fiber winding pipe manufacturers in the world than the other two production processes, one of the reasons is that the glass steel pipe produced by reciprocating fiber winding process has a wider application and better applicability.
