Који су фактори који утичу на перформансе заптивања производа од силиконске гуме?
Silicone rubber materials are widely used in the field of waterproof sealing because of their good resilience performance. However, in the product development stage, we have often encountered many companies encountering problems that the sealing performance of silicone rubber products is not good or does not meet the design requirements. , causing them a lot of trouble, so they came to us. Combined with our 25 years of experience in the silicone rubber industry, today I will share with you the specific factors that affect product sealing!
Производи од силиконске гуме
First of all, the sealing of the product is not a problem of a single product, but is composed of multiple parts. All parts that are in direct contact with the sealing surface of the product may cause seal failure no matter which product has a problem. To take a simple example, most seals The parts are composed of the upper shell and the lower shell plus a silicone rubber sealing ring/gasket in the middle. If the surface of the upper shell or the lower shell carrier is uneven, or the gap is too large, and the pressure variable is unreasonable, it may cause problems. occur. The deeper reason is the design problem, including product design, mold design, material design and so on.
Excluding these external reasons, let's talk about the reasons for the silicone rubber product sealing ring itself, the first material itself, according to the specific use environment of the product, such as the use temperature of the product, what substances are in contact with the product, etc. Choose the right material. The second is whether the appearance and size of the product manufacturing process meet the design requirements, burr control, dimensional tolerance, etc.
