Rubber processing — molding and extrusion — needs precise temperature control to manage cure times and maintain material consistency across production runs.
In rubber, mold temperature is directly tied to cure time and quality. Uneven temperature means uneven curing, and therefore deviations in dimensions and mechanical properties. Tool-Temp units are explicitly rated for rubber industry applications and hold a constant temperature across a full run. The choice between water and oil units depends on the target temperature — covered in the guide How to choose a temperature control unit. If mold temperature drifts despite a correct unit, causes and fixes are covered in Unstable mold temperature.
To remove process heat on longer runs, industrial chillers keep the cooling circuit stable and prevent temperature rise during operation.

Cure time depends directly on mold temperature. If temperature drifts, curing is uneven, causing deviations in dimensions and mechanical properties. A precise temperature control unit holds a constant temperature and part-to-part consistency.
It depends on the process. Water covers lower temperatures (up to about 90°C, pressurized up to 160°C), while oil units cover high-temperature processes up to 360°C. The right choice depends on the material and target mold temperature.
