Liquid Silicone Rubber
Liquid silicone rubber moulding is a thermoset process that mixes a two-component compound together, which is then heat cured in the mould with a platinum catalyst to produce a final LSR part.
We offer a number of secondary moulds and tooling services to support your project.
How It Works
Due to the flexible nature of LSR, parts are manually removed from the mould, and thus, ejector pins are not built into the mould design. Like a standard aluminium tool, an LSR moulding tool is fabricated using CNC machining to create a high-temperature tool built to withstand the LSR moulding process. After milling, the tool is polished by hand to customer specifications, which allows six standard surface finish options.
The finished tool is loaded into an advanced LSR-specific injection moulding press that is precision geared for accurate control of shot size to produce the most consistent LSR parts.
Since LSR is a thermosetting polymer, its moulded 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.
