Rubber seal extrusion mould design considerations

Mould design commonly used design software AutoCAD, Pro / E, UG, CATIA SolidWorks, etc., as the sealing strip extrusion products are not subject to length limitations; and the type of sealing strip does not only contain a single rubber sealing strip (pure rubber type sealing strips), but also contains a composite rubber sealing strips (composite sealing strips with metal support skeleton); In addition, sealing strips in the installation and use of process, will show very complex mechanical properties, such as material properties, geometric nonlinearities, boundary condition nonlinearities, etc., so sealing strip In addition, the sealing strip in the process of installation and use, will show very complex mechanical properties, such as material properties, geometric nonlinearity, boundary conditions nonlinear, etc., so the sealing strip molding process is very precise and complex, so in the design of the mould should pay attention to the shrinkage rate of the rubber of different materials, as well as the layout and internal structure of the product.
