Roll forming machines are machines that require high precision that produce various profiles from flat metal sheets. The fact that the profiles produced fully comply with the design specifications and are of high quality is of great importance for the end-use performance of the product. Therefore, it is essential to apply strict quality control in the roll form production process.
The Importance of Quality Control
Customer Satisfaction: Quality products increase customer satisfaction and lead to repeat business.
Brand Image: Product quality directly affects the brand image of the company.
Cost Reduction: Quality control prevents the production of defective products, thus reducing rework or waste costs.
Quality Control Methods Used in Roll Forming Machines
Process Control:
Roll Settings: Correct positioning and clamping of the rolls directly affects the size and shape of the profile.
Feeding Speed: Feeding the metal sheet at a constant speed ensures the smoothness of the profile.
Lubrication: Lubrication of the rolls reduces friction and improves the profile surface quality.
Online Measurement:
Laser Measurement Systems: The dimensions of the produced profile are continuously measured with laser technology.
Image Processing Systems: Defects on the surface of the profile are detected by image processing systems.
Sampling and Laboratory Tests:
Dimension Control: Samples are taken from the produced profiles at regular intervals and their dimensions are checked with precision measuring instruments.
Material Analysis: The chemical composition and mechanical properties of the profile are tested in the laboratory environment.
Surface Quality: Scratches, rust and other defects on the surface of the profile are examined under a microscope.
Statistical Process Control (SPC):
Data Analysis: All data in the production process are collected and analyzed by statistical methods.
Trend Analysis: Trend analyzes are carried out for early detection of deviations that may occur in production.
Control Standards: Control Standards are used to control the stability of the production process.
Visual Inspection:
Human Eye: The profiles produced are visually checked by experienced personnel.
Automated Image Processing Systems: In larger volume production, visual inspection is performed using automated image processing systems.
Quality Control Systems
ISO 9001: The quality management systems standard is widely used in roll form production processes.
TS EN ISO 10357: It is the tolerances standard for steel cold sections.
Key Benefits of Quality Control
Increasing Product Quality: Thanks to quality control, high-quality products are produced that meet customer expectations.
Reduction of Waste: By preventing the production of defective products, raw materials and energy are saved.
Increasing Customer Satisfaction: Quality products increase customer satisfaction and contribute to the company's growth of market share.
Increased Competitiveness: Companies that produce high-quality products have a more advantageous position in competition.
In conclusion, quality control in roll forming machines is an important activity that must be implemented at every stage of the production process. Thanks to quality control, customer satisfaction is increased, brand image is strengthened and production costs are reduced.
