A review with 3 refs. Thermal and flow-induced stress, d. variations, creep, and moisture absorption affect the dimensional precision of injection-molded products, but these phenomena are hard to understand. No abs. statements can be made with regard to the dimensional precision of injection-molded products at given material properties and process conditions. But the effect of process conditions and material properties can be estd. and, what's even better, understood with simulations, as discussed in this article on
