Experimental development of FRP pultrusion moulds

The paper work describes the pultrusion process and also selection of die raw material which is suitable for the production of constant cross-section composites of any desired length. It is a manufacturing process for producing various cross-section products in a mass production. As the product quality is purely depending upon the mold, such as the parameters of mold design, material of construction, mold length, hold down hole size & location, heat zones. And the process parameters like heating rate, pulling speed and the curing kinetics of resin system influent the mold quality. Die length, width & thickness of design will be standardized, based on the design die fabrication is done with the help of the Computer Numerical Control (CNC) machine, by using this P20 & EN8 dies, production was taken out and done experimental test on end product, based on the experimental & numerical test results and also finishing & quality. Comparing the two end product based on the result and quality of product taken from the P20 & EN8 dies, by the end of this composites production which was taken from the P20 die have best results, finishing & quality compare to EN8.
