The article analyses the impact of origin certification on the export activity and competitiveness of Kazakhstani machine-building enterprises in the Pavlodar region. Based on an online survey of representatives from 16 enterprises, it was found that most of them recognise the strategic role of confirming the origin of machine parts and components. Certification is used to strengthen trust on the part of foreign partners, simplify customs procedures and expand participation in international tenders. At the same time, systemic problems have been identified that are related not only to administrative barriers, but also to the need to increase the transparency and traceability of engineering and technical products. It is noted that the origin of the materials used directly affects the quality and safety of the final machine-building structures, and traditional paper certificates are losing credibility in the global market. Based on the data obtained, measures have been proposed to modernise the mechanisms for certifying origin, which will reduce the administrative burden and turn this process into a tool for increasing the competitiveness of domestic manufacturers of machine-building products in foreign markets.

The article presents the results of a study on the digitalization processes in the field of transport services, focusing on the assessment of the digital maturity level of transport and logistics companies in Kazakhstan. A systematic literature review based on the Scopus, Web of Science, and Science Direct databases was conducted, which made it possible to identify the main research directions in the field of Logistics 4.0 and digital transformation. Based on empirical data collected through a survey, an analysis was carried out of the factors influencing the digitalization of transport companies, including enterprise size, availability of digital technologies, implementation barriers, educational programs, and employees’ digital competencies. Correlation analysis was applied to identify relationships between the indicators, which revealed both positive and negative dependencies of varying strength. The results showed that the level of digital maturity is formed as a result of the complex interaction of technological, organizational, and human factors rather than being directly dependent on the size of the company. Digital transformation in the transport and logistics industry is associated with an increase in the complexity of processes and requires the support of human resources. The scientific novelty of the study lies in identifying key correlations between digitalization barriers, staff competencies, and the degree of technology implementation, which enables the development of practical recommendations for advancing digital transformation in Kazakhstan’s transport and logistics sector.

The article presents the results of a comprehensive study of the acoustic and damping properties of the new alloyed steels XSM-1, XSM-2 and XSM-3, developed to reduce the sound emission levels of machine components operating under impact loads. The relevance of the study is determined by the high prevalence of industrial noise and its adverse effects on the auditory system and cardiovascular function. The experimental work included melting and heat treatment of the alloys, determining their mechanical characteristics, as well as measuring sound pressure levels in the octave frequency bands of 125–8000 Hz under impact excitation using steel balls of various diameters. It was established that the new steels demonstrate reduced sound emission levels compared to standard grades St.10, St.20 and St.45. In addition, a pronounced amplitude-dependent damping effect reaching 7–9 dB in certain frequency ranges was identified. The results confirm the potential application of XSM-1–XSM-3 steels in structures requiring enhanced sound insulation, stable vibration suppression and efficient dissipation of impact-generated energy. These materials can increase equipment durability, reduce acoustic load on personnel, and ensure more stable operating conditions in industrial systems, which is particularly important for modern high-complexity technological processes with stringent safety requirements.

The article examines the influence of key 3D printing parameters, such as layer height and filling density, on time and material costs in the manufacture of samples of complex geometry from polylactic acid (PLA) using Fused Deposition Modeling (FDM) technology. Objects of various shapes were studied, including a parallelepiped, a cylinder and a blade-shaped structure, printed with different layer heights (0.10, 0.15, 0.20 mm) and filling density (15%, 20%, 30%) with constant parameters of temperature, printing speed and nozzle diameter. During the experiments, such indicators as printing time, material consumption and volume of the printed product were measured, which allowed for a comprehensive assessment of the economic efficiency and quality of the printed samples. The results of the study show that increasing the height of the layer significantly reduces the printing time, and increasing the filling density increases material consumption, while improving the mechanical characteristics of printed products. The study offers recommendations for optimizing 3D printing parameters to achieve the best balance between performance, quality, cost-effectiveness and strength characteristics, which is especially important for the application of additive technologies in engineering and industrial fields.

This article discusses the results of determining the specific electrical resistance (SER) of charge materials consisting of highly dispersed silica and petroleum coke, as well as the pyrolysis product of rice husks for the synthesis of silicon carbide. The high proportion of the formation of highly dispersed silica in the production of high-silicon grades of ferroalloys and metallurgical silicon requires the development of new technologies for the further disposal of man-made dust waste containing from 86 to 95.8 % SiO2. A similar solution is required by the by-product of rice production – rice husk, which almost does not burn, does not rot and is mainly sent to the dump, polluting the environment. A promising solution to these problems is the production of silicon carbide using these materials. For this purpose, in this work, work has been carried out to determine their SER in the Tamman laboratory furnace on a special pilot plant in the temperature range of 20 – 1700 °C at a heating rate of 15 degrees/min The electrical resistance of charge materials at specified temperatures determines the possibilities of synthesis of silicon carbide.

The article analyzes the current state and trends in the development of automation of marshalling yards, including key technological and organizational aspects that affect their effectiveness. The main problems such as incompatibility of solutions, insufficient integration of information systems, wear and tear of equipment and lack of models for synchronization of processes are revealed. The evolution of approaches to the design of automated systems from centralized architectures to distributed and intelligent ones is considered, which contributes to adaptation to the complexity of technological processes and the increase in information volumes. The importance of intelligent technologies for improving control accuracy and optimizing resources is emphasized. These solutions (regulation of wagon speed and control of switches), despite their primitiveness, became the basis for further development of automation technologies. With the development of computer technology in the 1970-1980s, automated control systems (ACS) appeared, which provided centralized control of marshalling processes. During this period, the main emphasis was on the automation of individual functions, such as retarder control and wagon movement control. However, centralized systems had significant limitations associated with insufficient flexibility, low fault tolerance and limited ability to process large volumes of data.

This article presents the results of experimental studies to improve the technological process of manufacturing parts such as gears and gears using nitriding instead of HDPE quenching for highly loaded equipment components of the mining and metallurgical complex. In recent years, there has been a tendency in Kazakhstan to concentrate the repair, mechanical and machine-building capacities of controlled enterprises of large corporations (ERG Group, KazMinerals and others) into single companies that ensure the manufacture, maintenance and operation of equipment, maintenance and development of repair and auxiliary processes at all enterprises of corporations. One of the defining approaches in substantiating the optimal technological process for the production of machine-building parts is the criterion of the required quality of products, which in turn includes reliability and, as a result, increased maintenance downtime of technological equipment. The traditional technology of manufacturing gears does not always provide sufficient durability for parts operating under high loads and friction. Another important criterion that is mandatory for mining and metallurgical equipment parts is corrosion resistance, since drives often operate in aggressive environments due to the peculiarities of technology. The hypothesis of the study is the use of nitriding as the optimal type of hardening treatment, which provides the gears of mining equipment with not only the necessary level of strength and durability, but also corrosion resistance. The purpose of the study is to compare the technological process of manufacturing parts such as gears and gears using nitriding instead of surface quenching with high-frequency currents. A comparative analysis of the characteristics and operation of the Gear part obtained using nitriding has shown the advantages of the proposed manufacturing technology compared to HFC heat treatment.
