PROTOTYPING, SMALL BATCH, AND LOW-VOLUME PRODUCTION
Liquid silicon rubber (LSR) moulding is the preferred manufacturing method for creating millions of different rubber parts, gaskets, valves, and much more. Silicone rubber has many manufacturing advantages. Parts made using silicone have excellent resistance to the effects of temperature, electricity, and chemicals making them appropriate across a span of industries. Silicone resists corrosion, temperature fluctuation, and electrical current placing the potential uses for LSR into the millions!
PRODUCING SILICONE CASTS
THE LIQUID SILICONE MOULDING (LSR) PROCESS
For small-batch and low-volume manufacturing of silicone casts, liquid silicone moulding is the fast and reliable manufacturing process. Thousands of identical moulds can be reproduced quickly using a single design and only one mould for expedited delivery of your silicone rubber parts. LSR is available in a wide variety of colours, has reduced weight compared to metallic parts, and is extremely resilient.
Every part – no matter the materials used – begins with a design. If you have a CAD file you can upload directly to our office but if not, feel free to ask our designers for help. Silicone reacts differently than other manufacturing materials; ensure your specs are accurate before producing thousands of units.
Like plastic injection moulding, GS Proto moulds are produced in our own factory, saving time and money. First a master model is produced via CNC or 3D printing. Then a silicone mold is created from the master model, which can then be used to quickly produce up to 50 duplicates of the master in a variety of materials.
SILICONE PART CASTING
Mould are injected with silicone the same way plastic injection injects polymers but with a key difference: unlike plastic injection molding where materials are heated and injected, LSR is chilled and injected into a heated mold, then cured. Cured silicone parts will not melt or warp when subjected to heat.
