Galaxy3DM uses a variety of methods to produce Silicone Mold and Molding parts. Our experienced engineers will select the best method for your project based on factors such as production volume, parts dimensions, budget, and other requirements.
Our extensive experience with LSR Molding enables us to produce innovative and cost effective parts for our OEM customers.
LSR molding differs slightly from thermoplastic injection molding due to its flexibility. Like a standard aluminum tool, an LSR molding tool is fabricated using CNC machining to create a high-temperature tool built to withstand the LSR molding process.
After milling, the tool is polished by hand to customer specifications, which allows six standard surface finish options.
From there, the finished tool is loaded into an advanced LSR-specific injection molding press that is precision geared for accurate control of shot size to produce the most consistent LSR parts. At Galaxy3DM, LSR parts are manually removed from the mold, as injector pins can impact part quality. LSR materials include standard silicones and specific grades to fit various part applications and industries like medical, automotive, and lighting. Since LSR is a thermosetting polymer, its molded state is permanent—once it is set, it can’t be melted again like a thermoplastic. When the run is complete, parts (or the initial sample run) are boxed and shipped shortly thereafter.

Typically, Protolabs can maintain a machining tolerance of +/- 0.003 in. (0.08mm) with a linear tolerance of +/- 0.01 in./in. (0.01mm/mm).
When selecting a material, consider the material properties, manufacturability characteristics, cosmetic appearance, and cost.
