Hsinchu, Taiwan — January 5, 2024 — In a recent feature published by Rubber World Magazine, Moldex3D, a leader in simulation technology, showcased its groundbreaking study on advancing liquid silicone rubber (LSR) molding processes. Authored by Harshal Bhogesra & April Brown from Moldex3D Northern America, along with Robert Jovingo and Kevin Barbee from Shin Etsu Silicones of America, the article highlights the critical role of Moldex3D simulations in preemptively addressing challenges during the product development phase.

The effective development of components is increasingly reliant on simulations, offering substantial savings by reducing the need for iterative loops in the prototype phase. Moldex3D collaborated with Shin Etsu Silicones of America and partner M.R. Mold & Engineering to lead efforts in understanding and resolving molding issues. The study utilized an optical LSR grade provided by Shin-Etsu, focusing on tooling, filling, and curing defects.

The showcase mold, featuring four strategically positioned cavities, was designed to highlight common molding challenges such as air traps, jetting, imbalances, short shots, flashes, voids, and uneven curing. Through a series of simulations, the team addressed issues like air entrapment, jetting, and imbalanced filling caused by the influence of gravity. This study demonstrates how Moldex3D simulations can provide preemptive solutions to these challenges, ultimately enhancing the efficiency of the LSR molding process.
