1. Hydraulic seals should have identification marks.
Usually, letters and numbers are used to mark the non working surface of the seal, but it must not affect the use of the seal. The logo should be eye-catching, clear, and of appropriate size. When it is not suitable to make a logo on hydraulic seals, detailed markings should be made on the packaging box (box). The content of the logo includes: product name, specification model, production inspection batch number, trademark, etc;
2. In principle, hydraulic seal products of the same batch and specification should be packed in one package.
Qualified products should be clean, free of dirt, dust, oil, etc. When packing, it is necessary to inspect the product quality at any time, verify the model and specifications, and prevent incorrect packaging or mixing of unqualified products. When packaging, it is important to protect the sealing lip and avoid tying or tying any part of the seal to prevent sharp objects from damaging the seal and packaging. Commonly used packaging can be made of hard and thick cardboard boxes, cardboard boxes, paper bags, woven bags, plastic bags, etc. The packaging should be strong, sturdy, lightweight, and easy to move or store. The packaging box should be accompanied by a product qualification certificate and packing list for sealing components. After packing, the specifications and quantity should be checked and confirmed to be correct before packaging. When sealing, it is not advisable to apply too much force or loosen the packaging to prevent deformation and loose packaging. The outer surface of the packaging box should be prominently marked with the name, quantity, and specifications of the contents. If it belongs to the goods to be shipped, the shipping box should indicate the origin and destination stations of the goods to be shipped;
3. During the transportation of hydraulic seals, they should be handled with care to avoid compression, throwing, and impact. During transportation, they should be protected from sunlight and rain. During storage and transportation, if stacking is necessary, it should not be too much, too heavy, or too high to prevent damage to the lower packaging and items inside. During the entire process of storage, packaging, and transportation, polyurethane seals should always be careful to avoid high temperature and humidity, and should not be squeezed to prevent deformation of the seals;
4. Before putting hydraulic seals into use, they should also be rechecked, especially for the working face, to ensure quality. If the temperature of the storage room used for temporary short-term storage is not at room temperature, the batch of seals should also be fully stored in a room temperature space, so that their temperature is close to room temperature before use, otherwise it will affect performance.
