Factory Inspection Procedures For Fasteners
Product quality is the enterprise’s lifeline, directly affecting its survival and development. Even if the product design is reasonable and the equipment is advanced, unqualified products still exist. Therefore, the quality inspection of products is very important. As one of the parts widely used in production, fasteners are used in high-performance products in high-tech fields such as aviation and aerospace and many areas of life. Due to the complex conditions of use, fasteners are affected by many factors.
As a professional fastener manufacturer, we are happy to introduce the fastener factory inspection procedure to you.
The surface inspection of fasteners is divided into two situations: first, the inspection before the plating of fasteners, including the inspection of the size, tolerance, etc., to ensure compliance with national standards or customer requirements; The second is the inspection after the plating of fasteners, mainly to check whether the color and surface of the coating are good.
- Check whether the color and material of the fasteners meet the requirements.
- The surface of fasteners should not be burr, deformation, damage, poor processing and other abnormal phenomena.
- The surface coating of fasteners should be uniform, and abnormal phenomena such as oxidation, rust, poor coating and paint shedding should not occur.
- Check whether there are other fasteners mixed, inconsistent length, missing accessories and other abnormal phenomena.
Performance tests for fasteners include tensile force, torsion, hardness, penetration, and corrosion resistance. The corrosion resistance test can be performed by smoke test: the fasteners are placed in the smoke box for 24 hours, then removed for cleaning and drying, and the rust phenomenon is observed within 24 hours.
