Quality Control Stages
- Metal Quality Control
At this stage, defectoscopy and ultrasonic testing are conducted to detect hidden defects in raw materials, along with a chemical composition analysis of the metal. This guarantees that the steel meets the necessary characteristics and maintains high quality.
- Dimensional and Geometrical Control
Every stage of production, from material preparation to the finished product, includes multi-level control of dimensions and geometric parameters. Special attention is given to precise measurements, tolerances, and deviations from set parameters, allowing for the timely detection and elimination of potential defects. This approach ensures not only compliance with technical requirements and standards but also stability in quality, which is a key factor in the reliability and durability of the product.
- Mechanical Properties Control
Hardness Testing (Brinell and Rockwell Methods)
To determine hardness, we use the Brinell and Rockwell methods, which assess the material’s ability to withstand mechanical stress. Conducting such tests is a crucial quality control step, ensuring that products meet the required standards even under challenging operating conditions.
- Tensile Testing
Each batch of products undergoes tensile testing to determine its strength limit. This test confirms that the product can withstand significant loads without losing its mechanical properties.
- Impact Toughness Testing
A key indicator of fasteners’ reliability is their ability to withstand sudden impacts or dynamic loads. Impact toughness testing ensures that the product remains dependable even under unexpected external influences.
- Torque Coefficient Determination
This test evaluates how the product behaves during installation, which is crucial for ensuring proper mounting and long-term performance.
