DE1704594B2 - PROCESS FOR MANUFACTURING ONE-PIECE, HIGH STRENGTH COVERED WITH GLASS FIBER REINFORCED CAST RESIN, E.G. COMPONENTS, IN PARTICULAR CLOSED WINDOW AND DOOR FRAMES - Google Patents

Description

Synthetic resin-impregnated glass fiber product is covered by this measure according to the invention

and after inserting the core and the casting resin introduced into the lower part of the mold

Closing the mold the resin is cured. 60 evenly in the mold when the core is immersed

Such a manufacturing process has a number of interiors between the inner mold wall and the core of Disadvantages, because once that has to be done by hand, the outer wall is displaced and soaked upwards The lining of the inner walls of the mold very much surrounds the fiberglass jacket. Needed by this tedious, time consuming and therefore expensive. You only need a fraction of the filling time as you normally would Others run the risk of shifting the 65 lining during the manufacture of comparable molded bodies when inserting the core, so that one is required. It is practical when the Inconsistent thickness of the glass fiber synthetic resin layer, the closing process of the form and the impregnation sequence is what leads to uncontrollable strength self-de- velopment process being carried out, which is therefore due to
