In 2013, the country’s largest bolt and nut production factory was established in Yazd with the name Sepand Pich Maftoli Industries in a land area of 85 thousand square meters.
The support of this opening was 30 years of continuous activity and gaining valuable experience in the screw and nut industry under the brand name Shireh Yazd (CHY), and in fact Sepand Peich Yazd (PSY) was established in line with the development plan of Shireh Yazd Company.
The purpose of this investment was to meet the needs of domestic industries, prevent mostly low-quality imports, and localize the technical knowledge of this industry. For this purpose, the country’s largest bolt and nut production factory was equipped with the most advanced and up-to-date machines and new technologies in this field.
Introduction of Sepand Pich Yazd company
In 1393, the country’s largest bolt and nut production factory was established in Yazd, Sepand Pich Wire Industries, on a land area of 85,000 square meters. The support of this opening was 30 years of continuous activity and gaining valuable experience in the screw and nut industry under the brand name Shireh Yazd (CHY), and in fact Sepand Peich Yazd (PSY) was established in line with the development plan of Shireh Yazd Company. The purpose of this investment was to meet the needs of domestic industries, prevent imports of mostly low quality, and localize the technical knowledge of this industry.
For this purpose, the country’s largest bolt and nut production factory was equipped with the most advanced and up-to-date machines and new technologies in this field. In the rest of the way, it was by relying on the knowledge of elite university youth and the skills of the country’s masters that this group was able to conquer the peaks of success and achieve the highest production tonnage and the highest variety of products in the country. One of the features of the large Sepand Pich factory in Yazd is the use of the most unique screw and nut production lines in the country.
In the Sepandpich factory, all the processes before screw production, i.e. wire preparation (phosphating, stretching and annealing) and all finishing operations after product production (thermal operations and coating work) are carried out sequentially and in an integrated manner. In this factory, the production of bolts and nuts in the form of cold forging (the process of pressing wire in a mold without the need to raise the temperature of the wire) has been chosen as the most suitable production method so that products with high precision and metallurgical quality reach the hands of consumers.
Sepand Pich Yazd services
With the support of 30 years of continuous activity in the bolt and nut industry of the country, we have gained a very valuable business regarding wire preparation processes. Considering the need of other industries for these services and due to the existence of required technical knowledge and sufficient experience in the organization, we decided to meet a significant part of the need of other industries by creating excess capacity of wire preparation. Despite the high technical complexity and the specialization of the preparation processes, Sepand Pich Yazd Company provides wire preparation services for all grades of wire such as steel, low carbon, medium and alloy and with various methods according to the needs and orders of the customer. to give
1. Pickling acid wash
In the process of acid washing, the oxides that are formed during the production of metal and rolling at high temperature, as well as fats, soot, rust and impurities that are created on the surface of metal are washed. and a completely clean surface is created for the next process, which is the phosphating process .
2. Phosphate Coating
In this process, the wire is immersed in a diluted solution of phosphoric acid and other compounds, the surface of the wire is chemically activated. After that, a strong and protective layer of insoluble phosphate crystals is created on the surface of the wire. The phosphate coating prevents direct contact of the wire with the tools in the drawing process and molds in the cold forging process and improves the wire's usability.
3. Drawing tension
In this process, the acid-washed or coated wire passes through the dies of the drawing machine mechanically and cold. This process is to size the wire to the required diameter for the cold forging stage. The stretching operation does not cause any change in the chemical elements of the wire.
The annealing process is a type of heat treatment that changes the mechanical properties of the wire. These changes cause the structure of the raw material of the wire to become a stable spherical work, and as a result, we will see a decrease in hardness, an increase in flexibility, and an increase in the workability of the wire. In fact, annealing heat treatment is the opposite of hard working heat treatment.
