The process for making moleded rubber parts

  The three main rubber molded parts manufacturing processes are compression molding, transfer molding, and injection molding Compression molding is the oldest and least expensive method. With compression molding, a rubber compound is formed into a blank. The blank then gets placed into a mold cavity to be shaped. The heating time is slow, which results in a long curing time; the heating can vary from three minutes for thin walls to 1 hour for thick walls. Some advantages of this method include being suitable for rubber compounds with large surface areas, and the ability to be used for rubber compounds with high viscosity and poor flow properties. On the down side, the process is time consuming with a low production rate. Some of the common products made with the compression molding process include rubber seals , o-rings, electrical insulators, and rubber pads. Transfer molding is a natural progression in development to limit the disadvantages of compression molding

What are the particle size measurement methods of ultrafine nano powder

  Ultrafine nano powder is an important product of the development of modern science and technology, which is widely used in such fields as electronic products, biomedicine and so on. The particle size of ultra-fine nano powder has an important impact on its performance, so the development of particle size detection technology of ultra-fine nano powder has also become a hot topic. As a company specializing in the research and production of ultra-fine nano powder, Saite also has rich experience and technical accumulation in particle size detection of ultra-fine nano powder. 1、 Common detection methods: The common detection methods for the particle size of ultra-fine nano powder are dynamic light scattering (DLS) and laser diffraction particle size analysis (LPS). Among them, the principle of DLS detection is to use the change in scattered light intensity to reflect the particle size of the sample, with a detection range of 1nm to 1 μ m. Suitable for detecting colloidal
