Our company manufactures and supplies components from aluminum alloys for enterprises in the electric power industry, petrochemical industry, mechanical engineering and other industries.
We use chill mold/PGS casting technologies.
The advantages of our production are:
- Compliance with the requirements for gas density of the casting.
- Casting tightness.
- Pre-eutectic structure of the casting material.
Products
We produce a wide range of products obtained by various casting methods. Today, our products are components for low- and high-voltage power lines, high-voltage switches and disconnectors (VGBE-35, VGT-110, VEB-110, RPD-110, RPD-220), flanges for feedthrough and support polymer insulators (IOSPK, OPN, etc.), products for general mechanical engineering, machine parts, etc.
We produce castings for all industries from the following alloys:
AK5 - AK5M2 - AK7 - AK7Ts9 - AK8M - AK9 - AK12 - AK12M2 according to GOST-1583-93
LC40 according to GOST-17711-93
Products can be shipped as cast blanks or as finished parts with mechanical processing.
The weight of one casting is from 200 g to 60 kg.
It is possible to manufacture castings and parts with special technical requirements for chemical composition, tightness, hardness, porosity, etc. We also select analogues of foreign alloys according to GOST.
We develop and manufacture technological equipment (including according to customer drawings):
- Model equipment
- Metal molds (chill mold)
- Production stages
| 1️⃣ Development of a casting drawing with the assignment of technological allowances and allowances. | 2️⃣ Determination of the method for obtaining a cast blank. (PGS/chill mold) | 3️⃣Issuance of a set of documentation for the production of technological equipment (set of MSO or chill mold) |
| 4️⃣Manufacturing of technological equipment | 5️⃣Production of a pilot batch in order to establish the conformity of the casting with the requirements of the drawing documentation. | 6️⃣Mechanical processing of castings (if necessary) |
Aluminum casting for the power industry
Today, in the power industry, the term "polymer insulators" is widespread, understandable and familiar.
The main design elements of any polymer insulator are usually the same:
- a fiberglass rod (pipe) that bears the mechanical load;
- metal flanges or end caps, with the help of which the insulator is attached to current-carrying parts and grounded structures;
- a polymer shell, which serves to protect the supporting fiberglass from atmospheric influences and forms the required length of the current leakage path.

We have carried out work on selecting a flange material with an expansion coefficient corresponding to the expansion coefficient of the insulator rod material at both negative and positive temperatures.
The material was selected from a range of aluminum alloys according to GOST 1583-93 with zinc, which meets all technical requirements and has high corrosion resistance and low specific gravity.
Since different manufacturers fasten flanges to the insulator using different methods (pressure fit, "hot fit", fastening with pins, etc.), by prior agreement with the customer, we can manufacture flanges of any shape, with any tolerance on the mounting hole and various connection dimensions.
Advantages of using aluminum flanges
 |
 |
 |
| Absence of welds in the cast flange, which are defect concentrators
|
The high strength of aluminum alloys significantly reduces weight compared to steel/cast iron flanges
|
No need for anti-corrosion galvanic coating followed by polyester powder coating |
Aluminum casting
is a process for producing aluminum products that involves pouring molten metal into a pre-prepared mold. This method is used to create a wide range of castings, from simple parts to complex structures. Aluminum, due to its lightness, strength and resistance to corrosion, is widely used in various industries, such as the automotive, aircraft, shipbuilding and household appliances industries.
Aluminum castings
have high mechanical properties and can be manufactured with high precision and detail. The aluminum casting process includes several stages: mold preparation, aluminum melting, pouring into the mold and subsequent processing of castings. Some methods, such as die casting, allow for ideal surface smoothness and minimal dimensional deviations, which makes products of higher quality and more durable.
In recent years, there has been an increase in demand for aluminum castings, which is associated with the trend towards lightweight structures and sustainable technologies. Innovative casting methods and modern alloys open up new opportunities for creating efficient and modern products in a wide variety of areas.
