TMT successfully relies on SIGMASOFT® Virtual Molding Vulcanization is the most important step in the manufacturing and processing of rubber products. Vulcanization time directly affects the performance of the final product. Compared with a conventional simulation, SIGMASOFT® Virtual Molding can better predict the vulcanization time of rubber and reduce the number of production trials and the cost …
In the very early stage of part development, when not much more than the part properties are known, SIGMASOFT® Virtual Molding can help to optimize the gating systems and the runner balancing. Where should gates be placed? How many cavities is optimum for a mold? What about the runner balancing? How robust is the runner balancing …
In order to improve the mechanical properties (especially the stiffness) of a part, glass fibers are often added to thermoplastic polymers. However, the thermo- mechanical material properties of the created compound are anisotropic (direction dependent). Due to the shear flow during injection, the local alignment of the fibers corresponds to a three dimensional flow situation, …
It is extremely common in the injection molding industry to use a cost calculation based on experience, relying on outdated excel tables and rough estimations. Many RFQs are not awarded due to miscalculations and poor predictions on overall costs. Customers are not always looking for low cost and quick turn around, but quality and delivery …

The selection of the ejection system is typically an intuitive process while designing an injection mold. Usually, the designer determines the best location for the ejection pins based on previous experiences. However, sometimes the performance of the ejection system deviates from the designer’s expectation. In the worst case, the contraction of the part towards the …
