Import rubber o-rings production factory is our common rubber products. It is widely used, the production process is relatively simple, and the materials used are many. Most of the damage to the O-ring does not come from design or pressure. If a good design only increases the pressure unilaterally, it will not cause damage to the O-ring. The fundamental reason is due to the working environment. Permanent deformation of O-rings under high temperature and high pressure and bites caused by being squeezed into the gap. So what are the reasons for the deformation of the Import rubber o-rings production factory?
1. Compression and stretch are essential factors
Due to the different formulations of the Import rubber o-rings production factory, the amount of compression and tension produced by different companies is also different. In the long-term compression state, the product will produce the imagination of compressive stress relaxation. This phenomenon will gradually expand with time. The longer the time is, the smaller the amount of compression and tension will be, resulting in insufficient elasticity and leakage. The direct change method is to increase the cross-sectional size of the product, but it will also lead to an increase in the structure of the product.

2. Temperature is a very important factor.
Temperature is very important for the relaxation of Import rubber o-rings production factory. No matter what kind of rubber material, its aging speed will be accelerated at high temperature. When the temperature in the environment is higher, the deformation of air compression will be greater. When the product is deformed by more than 40%, the o-ring will slowly lose its elasticity, causing leakage. When installing the Import rubber o-rings production factory there will be initial stress, which will gradually disappear due to the long-term relaxation of the sealing ring and the gradual decrease in temperature, and in some cases may be accelerated with the temperature. Even if the rubber material is low temperature resistant, it will not be greater than 25% of the stress generated at 20 degrees. Therefore, when setting the initial stress when installing the Import rubber o-rings production factory, it is necessary to fully consider the work. The temperature factor in the environment.
