How to aviod the Crack of rubber products?

The rubber cracking is one of the common quality problems of rubber products. The analysis of failure causes involves multiple factors, including environmental conditions, mechanical stress, processing technology, etc. For example, the internal pressure expansion and contraction experienced by rubber pipes during operation can accelerate the occurrence of cracking. The following are analyses and…

O-Ring Groove Design Principles

Though small in size, the O-ring plays a crucial role in ensuring the performance and reliability of a product. The O-ring groove design is key to ensuring a proper seal. A reasonable groove dimension allows the O-ring to be compressed sufficiently, achieving an effective and reliable sealing. In many cases, standard O-rings can be used, and the recommended groove dimensions can be found in…

Customized Bonding Rubber To Plastic Overmolding Solutions

Plastic and rubber bonding parts can combine the sealing properties of rubber and the rigidity of plastic. This rubber to plastic bonding design can achieve advantages such as good performance and lightweight. The rubber bonding(overmolding) process forms a strong bond between the rubber and plastic through the vulcanization process. However, due to the significant differences in the physical…

Conductive Rubber Application For Electromagnetic Shielding

Conductive rubber is a high-performance material that combines conductive properties with sealing functions. It achieves electromagnetic shielding and conductivity by uniformly dispersing conductive particles (such as nickel-plated silver, aluminum-plated silver, graphite-plated nickel, etc.) within different rubber material. Performance and Features Conductivity and Electromagnetic…

What factors are related to the coefficient of friction of rubber surface?

The coefficient of friction on rubber surface is influenced by the following key factors: 1.Material hardness: Generally speaking, surfaces with high hardness will have a lower coefficient of friction in comparison. 2.Surface Roughness: Higher roughness increases mechanical interlocking, leading to higher friction. However, moderate roughness can sometimes help reduce sliding…
