FRP pultrusion die is a mainstream product market. And most of all have glass glass steel sections pultrusion mold made of. FRP pultrusion die while carrying out the process of production, the factors affecting the pultrusion process are the following: (1) discharge yarn systems: the fiberglass roving or fabric pre-distribution systems. When the fiber-reinforced material transfer row yarn, flat yarn for discharge, generally using a rotary spindle, fiber from the bobbin outer leads, which prevents the reverse phenomenon. (2) resin impregnated: is arranged on a glass fiber mat uniformly impregnated neat and has formulated resin glue process. Resin impregnation is usually felt in the fiber and resin through the plastic tank fitted conducted, common trough dipping. Throughout the impregnation process must ensure that the fiber and felt very neatly arranged. (3) preforming: preforming device consists of a manifold, shunt bracket and guide bracket components. Good pre-impregnated fiber filled material through the pre-forming device, it operates in a continuous manner in order to ensure their relative positions; preformed by means of good fiber filled material impregnated gradual transition to approximate the shape of the profile, and squeeze out excess resin ; then into the mold, molding cure. Guide support generally in the mold inlet, preforming device and fiber-reinforced material contacts the smooth surface should be trimmed to prevent the fibers shaving. (4) molding and curing: profile already having been dipped in the approximate shape of a fiber reinforced material into the mold, the molding was cured in a mold. Temperature of the mold is designed according to the resin system, the main heat curve according to the material and the mold resin and friction properties. Usually the mold is divided into a preheating zone, a gel zone and curing zone two different heating zones to control the curing speed. Mold is a pultrusion process is the most critical part of the length of the typical mold of between 0.6 ~ 1.5m. (5) Traction Cutting: In fiberglass pultrusion die, the traction device may be a track-type tractor, it will pull out of the cured profiles from the mold. General should have more than 98kN of tension. Source: "FRP pultrusion die in pultrusion key factor", as detailed in www.jinglong2008.com/news/13.html [ZQ]
