В статті розроблено математичну модель руху суміші полімерного матеріалу з армуючими частинками у процесі заповнення порожнини прес-форми, яка, на відміну від наявних, дозволяє спостерігати за формуванням структури полімерного виробу із включеннями, що дає можливість конструювати і проектувати оснастку для лиття під тиском виробів легкої промисловості з підвищеними експлуатаційними властивостями.
Ключові слова: полімерний матеріал, технологічний процес.

Today, recycled polymer waste can be used in most light industry processes, including injection molding, compression molding, extrusion and calendering. The most acceptable technological processes are those having a wide range of technological parameters, that is, those that do not require narrow specification. Therefore, it is desirable to use recycled polymeric material in the manufacture of new light industry products which are obtained by injection molding or extrusion. Other methods of forming polymeric products of light industry can be applied only in cases where the secondary polymer has properties close to the original. The most promising technology for producing polymer products using a significant proportion of recycled polymeric waste today is injection molding of polymer products with the introduction of secondary polymers as a binder. Understanding the processes that occur when forming the structure of a material with a filler, will allow you to design and design injection molding to obtain polymer products of light industry with high performance properties. In order to do this, the filling of the mold cavity with polymeric material with the inclusion of recycled waste particles should be modeled first. The article develops a mathematical model of the motion of a mixture of polymeric material with reinforcing particles in the process of filling the mold cavity, which, unlike the available ones, allows to observe the formation of the structure of the polymeric product with inclusions, which makes it possible to design and design injection molding for obtaining light industry products with high performance.
Keywords: polymer material, technological process.
