Manufacturing thermal silicone rubber gaskets involves a series of process steps and material selection, the following is the general manufacturing process:

Material preparation: Select high-quality thermal conductive silicone rubber raw materials, usually silicone rubber with thermal conductive fillers, such as alumina, boron nitride or metal powder, to improve its thermal conductivity.

Mixing: The silicone rubber is mixed with the thermal conductive filler, which can be achieved by mechanical mixing or rubber extruder. The mixing process will ensure that the thermal conductive filler is evenly distributed in the rubber to ensure that the gasket has good thermal conductivity.

Calendering: The mixed silicone rubber block is processed into the required gasket thickness by calendering machinery or calendering process. A die can be used during the calender process to ensure that the shape and size of the gasket meet the requirements.

Cutting: According to the specific application requirements, the rolled silicone rubber sheet is cut into the required size and shape.

Hardening: Silicone rubber requires vulcanization or heat curing to increase its heat resistance and stability. This is usually done at high temperatures, and the time and temperature are adjusted according to the silicone rubber formulation and thickness.

Surface treatment: According to needs, the surface of the thermal conductive silicone rubber gasket can be treated, such as coating the thermal adhesive or adhesive, in order to better connect with other materials.

Inspection: Quality inspection of manufactured thermal silicone rubber gaskets to ensure that they meet specific performance requirements and dimensional accuracy.
