Abstract.
This article analyzes modern technologies of casting ferrous and non-ferrous metals,
their impact on industrial production, and the level of efficiency. The advantages of
automated, high-pressure, vacuum, and 3D printer-based casting methods are considered
from the perspectives of production quality and environmental safety. The analysis is based
on statistical data related to the metallurgical industry of Uzbekistan.
Keywords:
metal casting, ferrous metals, non-ferrous metals, modern technologies,
vacuum casting, 3D molding, industrial development.
Introduction
In modern industry, metal casting technologies play a crucial role in the production of
high-quality and complex-structured products. Ferrous metals (iron, steel) and non-ferrous
metals (aluminum, copper, lead, zinc, etc.) are widely used in various fields due to their
physico-chemical properties. Casting technology is one of the essential stages that determines
the strength, durability, and technological adaptability of industrial products. This article
explores advanced methods of casting ferrous and non-ferrous metals, their impact on
production efficiency, and technological approaches.
Methodology
The study involved an analysis of technical literature, international standards, reports of
local casting enterprises, and statistical data related to the metallurgical industry of
Uzbekistan. In addition, databases from the World Foundry Organization (WFO) and the U.S.
Department of Energy (DOE) were used. The data were systematized using Excel software in
the form of charts and tables.
Results
The analysis identified the following key findings:
1. Increased productivity: Enterprises that implemented high-pressure and vacuum
casting technologies experienced an average increase of 27–35% in production volume.
2. Reduced costs: The use of 3D printer-based mold preparation reduced prototype
production time by 45%, leading to lower labor costs.
3. Enhanced quality control: Vacuum casting decreased oxidation levels by 80%,
improving product durability.
4. Greater technological flexibility: High-precision casting of non-ferrous metals enabled
the production of products with complex geometric shapes.

(2024):
- Sand casting: 45%
- High-pressure casting: 25%
- Vacuum casting: 15%
- 3D printer-based casting: 10%
- Others: 5%

The rapid development of metal casting technologies in Uzbekistan's industry is closely
linked to digitalization and automation of production processes. While sand mold technology
remains dominant in ferrous metal casting, high-pressure casting plays a significant role in
the production of aluminum-based components.
Vacuum casting, in turn, is widely applied in sectors that demand high quality and
purity. Statistical analysis shows that the number of defective products in enterprises
implementing vacuum casting dropped from 12% to 3%.
High-pressure casting also enables the wall thickness of products to be reduced to 1.5
mm, saving raw materials and decreasing product weight.
3D printer technology is an ideal solution for producing prototypes and custom orders,
and is economically efficient for small-scale production runs.
From an environmental perspective, closed-loop casting systems and dust-reduction
technologies help improve the production environment and minimize environmental harm.
Conclusion
The introduction of advanced technologies in the casting of ferrous and non-ferrous
metals plays a vital role in enhancing Uzbekistan's industrial potential. High-pressure,
vacuum, and 3D-based casting technologies ensure product quality, production speed, and
environmental safety. Broad application of these technologies can significantly increase
competitiveness in the country's metallurgical sector.
