A model is proposed describing the orientational effects on crystallization of a polymer in the conditions of its flow along the shape-forming surface. The influence of the technological regimes and the conditions of the process on the parameters of orientation crystallization has been studied experimentally and theoretically. The extremal nature of the dependence of the degree of orientation on the distance to the centre of the channel during flow of the melt through the shaping cavity has been established. The dimensional effects of the mechanical properties of the cast materials are presented and explained with reference to the result obtained.

An analytic expression is obtained for the specific heat of the vacuum metallization process. Optimal values of the evaporation temperature are determined for a number of metals and maximal deposition rates are estimated at which thermal rupture of the polymer materials does not occur.

The variation in density of active centers is described by a diffusion equation of hyperbolic type, which is solved by numerical methods. The results of the calculation are compared with known experimental data.
