Extrusion Line
Production Process
Our extrusion lines are equipped with the most advanced technology to produce high-quality profiles. In addition to standard profiles, we produce general-purpose and special-purpose profiles used in various industries, including automotive, advertising, furniture, heating, cooling, transportation, and construction.
What is Extrusion?
Extrusion is the process of shaping materials with a defined cross-section and a small cross-section-to-length ratio (i.e., length much greater than width) into profiles. This process involves forcing the raw material through a die under a force, resulting in the profile. Extrusion is also a section reduction process, where the cross-section of an aluminum billet is converted into the cross-section of an aluminum profile.
Process Efficiency and Mold Selection
During the production process, the degree of difficulty is determined by how closely the cross-section of the billet used matches the profile to be produced. Therefore, the correct design of profile molds and the selection of the appropriate extrusion press are crucial. The production of thin and small profiles requires smaller billets and a press with adequate force, while the production of large profiles requires larger molds, billets, and presses.
Extrusion Process and Heat Treatment
During the extrusion process, billets are heated to 420-470 degrees Celsius, while the mold temperature is raised to 450 degrees Celsius. Profiles emerging from the press reach temperatures exceeding 500 degrees Celsius. The profile is cooled, stretched, and cut to the desired length. Artificial aging is performed to ensure the profiles maintain their desired mechanical properties.
Dimensional Tolerances and Standards
Profile dimensional tolerances are determined by various national and international standards. Production outside these standards is subject to agreement between the customer and the manufacturer. However, it should be noted that producing profiles with tighter tolerances than the standards will also result in higher costs.
Our extrusion lines are meticulously inspected at every stage to ensure high-quality production. This ensures we deliver the best possible product to our customers.
