For the storage of inspection fixtures, they should be stored in zones according to their precision level. High-precision inspection fixtures, for example, need to be stored in a constant temperature and humidity environment, with the temperature controlled at 20 ± 2℃ and the humidity maintained between 40% and 60%, to avoid dimensional deformation caused by temperature and humidity fluctuations.
Regular rust prevention treatment of inspection fixtures is crucial. Rust-preventive oil can be applied, generally conforming to GB/T4879 standards, and reapplied every three months to prevent rust and corrosion on the metal surface. When inspection fixtures are received into the warehouse, detailed registration should be carried out, recording information such as model, specifications, production batch, and number of uses, establishing a complete file management system for easy subsequent retrieval and traceability. Shelves for storing fixture molds should be customized according to their shape and size. For large molds, heavy-duty shelves with strong load-bearing capacity should be used, with each layer capable of bearing no less than 2 tons to ensure safe and stable storage. Critical components of inspection fixtures, such as cores and cavities, should be individually protected and packaged. Use cushioning materials such as pearl cotton and bubble wrap to prevent collision damage during handling and storage.
During storage, perform regular functional checks on the inspection fixtures. According to relevant industry standards, such as the JB/T8071 standard for the machinery industry, conduct a comprehensive functional test every six months to promptly identify and repair potential problems. The storage environment for the inspection fixtures must be kept clean. Professional cleaning equipment should be provided, and cleaning should be carried out at least once a week to prevent dust and debris from entering the inspection fixtures and affecting their performance. For inspection fixtures that are not used for a long time, they should be sealed. Apply a sealant evenly to the surface of the fixture, then seal it with plastic film to reduce contact with air and extend its service life. Establish a strict inbound and outbound management system. Strict inspection and registration should be carried out when fixtures and molds enter and leave the warehouse to ensure accurate quantity and good condition, and to avoid mis-shipment or omissions.
