Creating new potentials to bring TKV Mechanical to approach the industrial revolution 4.0


Over the past years, the mechanical units of the Vietnam Coal and Mineral Industries Group (TKV) have continuously promoted investment in equipment, technological innovation and production lines to increase mechanical engineering capabilities. create and localize products to meet coal production needs. However, the results are not as expected, while the potential of TKV Mechanical Engineering is still high. In order to fully exploit the existing advantages of a developing member, give TKV Mechanical a new potential, and approach the industrial revolution 4.0, it is necessary to clearly define the capacity and potential. capabilities and development opportunities of TKV Mechanical Engineering in the current context. Therefore, in order to become “Mechanical Engineering” and one of the main industries in the multi-industry business strategy, TKV Mechanical must have products bearing its own brand, must reach out to dominate the domestic market and creating a premise for export, strongly proliferating endogenous technology and increasing the ability to assimilate imported technology.

Opportunities and challenges from Industry 4.0

The 4th Science and Technology Revolution was formed based on combining digital with high technologies to create smart technologies such as 3D printing, robotics, artificial intelligence, and Internet of Things. objects (IoT). Future manufacturing will combine the fields of physics, digitalization and biology, network of virtual worlds (software, networks) and real world (machines and devices)… close together. The convergence of top-notch technologies allows optimal use of resources, saving labor, saving investment, saving time,… in the process of research – manufacturing technology and organization. production organization and is seen as an opportunity and a challenge for the economic sectors of developing countries. If grasped and oriented, it will be an opportunity to accelerate development speed; on the contrary, if not grasped, the risk of technical backwardness and economic backwardness will be present in the immediate future.

TKV Mechanical Engineering is a mechanical engineering industry serving the field of mining and processing of solid minerals with its own unique characteristics that are no exception to that rule, including challenges and opportunities for development.

The most basic challenge is that the current technological and technical background of TKV Mechanical is still quite outdated, the technology level is mainly still at the level of the 2nd Industrial Revolution with many difficulties and problems: (i) No core technology, no mastery of material technology; (ii) Processing is mainly in the form of single units and small-scale; (iii) Sector linkage, regional linkage is still limited; (iv) The scale and potential of enterprises are limited, lack of competitiveness in the region; (v) The competition is getting fiercer, not only in the industry, but also in the region and internationally.

Besides, Industry 4.0 also brings TKV Mechanical many opportunities. With the increasingly strong development of digital technology, communication, and specialized software, it will be both a promoter and a support for manufacturing enterprises to change production methods in the direction of increasing efficiency. , Cut the cost. The outstanding development of processing technology and the modernization of technological equipment will create good opportunities for TKV Mechanical to access modern science and technology, optimize the production process, and facilitate technological innovation. technology and have many opportunities to participate in regional and global supply chains. TKV mechanical engineering as well as other enterprises will benefit from the suppliers (technology, equipment, technical materials) of developed economies when competing with each other to increase quality, schedule and cost.

Step by step mastering design and technology

The Group’s mechanical engineering division currently has 12 units, including 11 mechanical manufacturing companies and 01 specialized research institute, the Institute of Energy and Mining Mechanics, with a total workforce of 3,150 people. The division’s revenue is about 5,000 billion VND per year.

Most of the Mechanical Manufacturing Plants of TKV were built from the 1960s to the 1970s with the help of the former Soviet Government. Most of the technological devices are old universal machining equipment with a low level of accuracy.

According to the previous development planning and orientation, TKV Mechanical is designed, invested in equipment and production processes mainly serving the repair of specialized equipment in open-pit mining and processing. coal transformation.

In the last 10 years, TKV has advocated accelerating the transformation from Repair Mechanics to Manufacturing Mechanics, step by step mastering design and technology to manufacture imported replacement parts and equipment. The production units of TKV Mechanical have invested and equipped with many modern and synchronous technological equipment in precision machining stages and are gradually automating the production stages.

(vii) Gradually manufacture and export spare parts and equipment used in mining and mineral transportation to the international market, typically: Wear-resistant parts of Combai machines; Ball bearings, battery shafts in large capacity transport equipment; Roller conveyors;…

In addition, many equipment that was previously imported from developed countries such as Poland, Russia, Japan and China has been partially localized by TKV Mechanical, manufacturing all kinds of spare parts. to be proactive in production and reduce equipment investment costs. Currently, TKV Mechanical is completing the product standard system, calculating the localization rate and gradually paying attention to the branding work to help the market have more information to identify the products. mechanical brand TKV.

Modern machinery is invested by Automobile Industry Joint Stock Company – Vinacomin, in order to meet the manufacturing and repair capacity.

Maintain production through the pandemic

2021 is the second year the economy is greatly affected by the Covid-19 pandemic, in which mechanical engineering is a manufacturing industry that has suffered double impacts from the decline in market demand due to reduced production in other economic sectors. exports, and at the same time suffers additional impacts because the supply of materials and spare parts, especially imported ones, tends to be scarce and unstable in price. With TKV Mechanical, the Covid pandemic has a double impact on production and business results. In which, the biggest impact is the supply of imported materials and spare parts, which is affected both in terms of progress and price stability. Besides, many economic sectors adjusted to reduce output, leading to a decrease in supply in the market, leading to high production costs.

The production and business results of TKV Mechanical in 2021, basically still ensure the growth in sales revenue targets, but the efficiency indicators are significantly reduced. Total revenue in 2021 of the whole Division (11 units) reached VND 5,441.73 billion / VND 4,038.26 billion of the plan (plan), reaching 134.8% of the year plan and equaling 122.9% of the revenue realized in 2020 The average salary of the whole Group is 9,635 thousand VND/person/month, reaching 112.8% of the plan and equaling 103.7% compared to 2020. The proportion of average income growth is much lower than the growth rate. The corresponding revenue correctly reflected the increased value of revenue due to the increased value of cost cost.

High and unstable raw material prices lead to increased financial costs, some small-scale units have a lot of influence on production capital. The costs incurred related to the cost of disease control, testing, production organization 3 on the spot, … affect the production and business efficiency of enterprises. Therefore, the profit before tax of the Mechanical sector in 2021 is estimated at 44,820 million VND, reaching 117% of the plan and equaling 103.2% compared to 2020.

Continue to build TKV Mechanical for Safe – Sustainable – Effective development

Aware of changes in the macro environment in the coming period when Vietnam promotes the process of industrialization and modernization and strengthens international integration, Vinacomin soon organized a study to re-evaluate the current situation of enterprises. , analyze strengths and weaknesses to find development opportunities in the next period, which is reflected in the TKV Mechanical Development Strategy for the period of 2021-2025, with a vision to 2035.
