Extrusions
Rubber & Silicone Extrusion process
SJG produce bespoke extrusions to specific customer requirements
Manufacturing Process
- Compound – Arrives formulated to customers’ requirements in strip form and ready to be feed into and extruder.
- Extruder – Has a heated screw that both masticates and heats the compound up under pressure in the chamber before being formed by the die.
- Die – The die is made to customers’ requirements, it will shape the compound to the desired profile before vulcanization.
- Vulcanization – The profile is cured via a salt bath where the temperature is between 170 – 260 oC, ready for end of line requirements.
- End of line – The profile will either be cut or coiled to customer requirements, additional it could require additional processes via our in house conversion processes.
- Conversion – The profile could be moulded, cut, drilled, taped or lubricated to any requirements specified.
