Abstract

The invention relates to a device assembly and methods useful for producing molded silicone rubber products from liquid silicone rubber compositions ('LSR') via injection molding. The methods provide a flexible process to produce faster cured silicone rubber products from LSR and allow for use of low curing temperature in the molding cavities without drastically lowering cure speed of the LSR and the physical properties of the produced molded silicone rubber material, therefore allowing liquid silicone rubber overmolding on or over heat sensitive substrates. The device assembly of the invention allows a faster cycle and the use of precise dosing and mixing units thus creating a flexible process to produce cured silicone rubber products faster from liquid silicone rubber (LSR).
