First, a liquid silicone rubber molding tool is created using CNC machining. This tool must be a high-temperature tool in order to withstand the LSR injection molding process. The tool may then be polished to allow for different finish options.
Next, the finished tool is loaded into an LSR-specific injection molding press that is precision geared for accurate control of shot size to produce the most consistent LSR parts. Materials used include standard silicones and specific grades to fit different part applications. Because LSR is a thermosetting polymer, its molded state is permanent. Unlike thermoplastics, they can’t be melted again. Once the LSR injection mold parts are ready, they are removed from the mold and then put to use as prototypes or production parts.
Our basic guidelines for silicone rubber molding include important design considerations to help improve part moldability, enhance cosmetic appearance, and reduce overall production time.

SPI surface finishes:We offer any type of SPI surface finish, such as A-1, D-2 or D-3.
VDI surface finishes:VDI 3400 Surface Finish (commonly known as VDI surface finish) refers to the mold texture standard set by Verein Deutscher Ingenieure (VDI), the Society of German Engineers. This is mainly processed by EDM machining, producing fine to coarse matte finishes.
