PARAMETER CONTROL IN THE PROCESS OF MANUFACTURING PRODUCTS USING MIM TECHNOLOGY

Background. The article is devoted to methods of controlling the technological process of manufacturing products using MIM technology (Metal Injection Molding), which is a promising direction for achieving technological sovereignty and modernization of production. The aim of the work is to improve the quality parameters of products manufactured using MIM technology by analyzing the key stages of the MIM process and monitoring the technological modes that cause defects in products at each stage. Materials and methods. The study used metal powders (stainless steel, titanium, copper, etc.), binding components (wax/polymer and polymer/polymer), as well as modern methods of analysis: electron microscopy, laser diffraction, gas pycnometry, radiographic control, capillary and moment rheometry. The stages of production are analyzed from the point of view of quality management: preparation of granulate, injection molding, removal of binder (thermal, solution, catalytic methods) and sintering. Results. It was found that the quality of the granulate and the uniformity of the distribution of components critically affect the absence of defects in sintered products. The optimal parameters of casting (temperature, pressure, injection rate) and sintering (temperature profiles, furnace atmosphere) are determined. It is shown that modern control methods (for example, mass spectrometry, laser scanning) can minimize defects and improve the mechanical properties of products. Conclusions. The use of integrated control at all stages of MIM technology ensures high product quality, reduced defects, and compliance with requirements for critical applications (aerospace, medicine). Special attention is paid to the need for standardization of processes and the use of automated monitoring systems to improve production efficiency.
