MOULD FOR PRIMARY SHAPING IN PLASTIC DEFORMATION OF PARTS FROM MATERIALS YIELDING TO THERMAL EFFECTS Russian patent published in 2012 - IPC B29C33/02 

FIELD: process engineering.

SUBSTANCE: invention relates to metallurgy. Proposed mould has fibrous composite structure and electric resistive heater. Note here that carbon fibers or carbon filaments are introduced in mould plastic matrix, in zone of shaping surface. Note here that said fibers or filaments in plastic matrix define mould mechanical properties, primarily, durability, rigidity and/or thermal expansion. Said electric resistive heater is connected so that its separate sections make electrical parallel connections. Note also that system forming said heater represents biaxial or multiaxial tissues or packages from carbon fibers or carbon filaments.

EFFECT: higher reliability and efficiency.
