Abstract
. The article examines the influence of eight variable factors (input parameters, such as the percentage of resin - Pr,
humidity - H, molding temperature – Tm and the regional value of the type-size - R, holding time τhold of details in the form under
pressure) on the absolute calculated shrinkage of the outer (D) and inner diameters (d) of the bushings. It has been established that by
controlling the operating parameters (Р,Т,τ), it is possible to achieve the required accuracy and quality of details made of thermoactive
materials. It was determined that the shrinkage of the studied materials predetermines their quality indicators (accuracy, strength,
hardness, etc.). It has been experimentally established that from the operating parameters, the pressing pressure and holding in the press
form strongly affect the quality of details made of thermoactive materials.
