Q Q1. True or False Questions (put “T” or “F” below for each questions, each 10 pts) 1.Unlike thermoplastics, reactive materials undergo simultaneous forming and polymerization during the molding process. 2.The typically low viscosity of the reactive materials permits large and complex parts to be molded with relatively higher pressure and clamp tonnage than thermoplastics molding. 3.For reactive molding, the reason that the part temperature in the cavity often exceeds the mold temperature is the chemical reaction (or crosslinking) is exothermic. 4.___ Structural foam molding produces parts consisting of solid external skin surfaces surrounding an inner cellular (or foam) core. 5.___ For thin wall injection molding, the thicknesses are less than 2 mm. 6.Due to the high velocity and shear rate in thin-wall molding, orientation occurs more readily than conventional molding.
