Pultrusion line equipment and manufacturing processes

Downstream along the production line, the rovings and mats are dispensed from a set of spools, stacked on metal racks or creels (Fig. 9.3(a)). The 

3 Different stages of the pultrusion process (a) creel and mat racks for fibre handling (b) orifice plate (c) open bath (courtesy of ALTO) (d) preforming guides (e) cutting system (courtesy of Strongwell). 

Reinforcing mats can be spliced by inserting the tapered end of a new roll on the split tail of the old one and sewing. 

The fibre reinforcement architecture (position and alignment) of apultmded part is defined by a guiding system that consists of contact points (ceramic guidance eyes ) and orifice plates that are usually made of polished or chromed steel or high-quality polyethylene in order not to damage the fibre reinforcement. 

Some pultrusion lines include dust extraction systems for reasons of both environment and tidiness take-off systems that are used to handle and store the produced parts and/or tuimel heaters used for post-die curing operations that improve the physical and mechanical properties of pultruded parts.
