Workflow
Production
Material Types
Izkon offers a wide range of materials in the production of fastening elements. The main materials used in production include alloy steel, carbon steel, and stainless steel. Additionally, our products are manufactured in quality classes 4.6, 8.8, 10.9, 12.9, and 14.9. Each quality class is selected based on specific requirements for high durability, corrosion resistance, and mechanical properties.Surface Protection Types
Various surface protection processes are applied to ensure the long lifespan of the products. These processes include electrolytic coating, hot-dip galvanizing, geomet coating, and phosphate coating. This makes bolts and other fastening elements more durable against harsh environmental conditions.Steel Selection and Sizing:
The steels used in bolt manufacturing are generally carbon steel or alloy steel. The ideal material for bolt production is selected as a type of steel that is high-strength, low-cost, and easy to process. It is then sent to the saw according to the required dimensions for the order.
The materials coming from the saw are,
Heating Method: “Induction heating systems are used. Induction heating provides faster and more controlled heating,” making the material ready for the forging process
Forging Process:
– Pre-Forming: The heated steel is placed into forging machines (hydraulic presses, friction press, eccentric press) to take its initial shape. In this process, a portion of the metal is forced into forging molds to shape the part as desired. This stage is generally used for shaping the bolt head.– Finishing: After the bolt head is shaped, the remaining part of the metal is passed through another mold to take a thinner and longer shape. This step prepares the body and thread portions of the bolt .
Bolt Head Shaping:
The head of the bolt is another critical part shaped during the forging process. This head is usually round, hexagonal, or square. The shaping process often involves forging, and commonly used head shapes include hexagonal and cap-style expanding designs. The head is typically formed with the aid of a mold.
Machining:
– The machining phase of bolt production involves the final processing steps. This stage is especially critical for precisely forming the bolt’s thread structure.
Thread Rolling: The threads of the bolt are typically formed through a process called “thread rolling.” In this process, no material is cut; instead, the shape of the metal is altered, resulting in threads that are stronger and more durable.

Surface Treatment Coating:
To enhance the durability of bolts, surface coating processes such as galvanizing, nitriding, chrome plating, zinc plating, or Geomet coating can be applied. These treatments make the bolts more resistant.
Sizing, Testing, and Packaging:
The final stage of bolt production is quality control testing. This step includes tests to verify the bolt’s durability, dimensions, and overall functionality. The completed bolts are packaged and prepared for distribution, ensuring delivery within the specified time frame.
