For many years, the folks at Sigma Engineering GmbH (Aachen, Germany) have marveled at the ingenuity of customers using its SigmaSoft Virtual Molding system to trim costs and optimize standard operating procedures. This year, for the first time, Sigma has decided to publicly acknowledge those customers that have taken full advantage of the molding simulation technology to achieve design and production efficiencies. The inagural 2017 SigmaSoft award went to hot-runner company Günther Heisskanaltechnik GmbH (Frankenberg, Germany) and moldmaker Speedturtle (Batalha, Portugal). The awards were presented to the companies during SigmaSoft’s International User Meeting last month.

Günther Heisskanaltechnik uses SigmaSoft simulation technology to optimize the design of its hot-runner systems. The hot runners can be mounted on the mold immediately at customer sites, allowing continuous processing of the polymer because of uniform temperature distribution from the connection nozzle over the manifold and hot runner nozzle to the cavity, explained Marco Kwiatkowski, Head of Production and Development, Thick Film, at Günther. “Because of the thermal evaluation of our manifold systems, we can eliminate unbalanced filling of cavities due to hot spots or cold areas,” said Kwiatkowski.
Portuguese moldmaker Speedturtle only started working with SigmaSoft in mid 2016. Since then, General Manager Marco Ruivo and his team have already optimized a number of molds through the use of simulation technology. “Using SigmaSoft, we take more time during the first steps in designing a new mold, but, in the end, we can deliver to our customers much faster, as we have fewer iterations for each mold,” said Ruivo.
“Our customers use simulation on a very high level,” added Thomas Klein, General Manager at Sigma. “With the Sigma Award, we want to acknowledge how they solve complex and challenging questions with the help of our software.”
Sigma is a sister company of Magma, which develops casting process simulation systems. SigmaSoft virtual molding technology optimizes the manufacturing process for injection molded plastic components. It combines the 3D geometry of the parts and runners with the complete mold assembly and temperature control system and incorporates the actual production process to develop a turnkey injection mold with an optimized process.
