Production process flow of thermal conductive silicone

Thermal conductive materials are a new type of industrial material. These materials have been designed in recent years to meet the thermal conductivity requirements of equipment, with excellent performance and reliability. They are suitable for various environments and requirements, have appropriate countermeasures for possible thermal conductivity problems, provide strong assistance for highly integrated equipment, and are ultra small and ultra-thin. Thermal conductivity products have been increasingly applied to many products, improving product reliability.

Thermal conductive silicone has high thermal conductivity, good processability, and good mechanical properties, and is widely used in fields such as electronics, communication, aviation, and automobiles. Thermal conductive silicone products are mainly used for heat dissipation and conduction in circuit boards, high-end LED lighting fixtures, power supplies and other equipment. Meanwhile, thermal conductive silicone can also be made into various shapes of thermal conductive products, with a wide range of applications.

The preparation process of thermal conductive silicone includes steps such as raw material preparation, mixing, defoaming, filling, and curing.

1. Raw material preparation

According to actual needs, weigh and prepare various raw materials into containers using an electronic scale according to the proportion of raw materials in the formula.

2. Mixing

Put the prepared raw materials into a planetary centrifugal mixer for rapid mixing to ensure full mixing of various raw materials.

3. Defoaming

Put the mixed raw materials into the defoaming machine for vacuum defoaming to remove the bubbles generated during the mixing process, in order to improve the reliability of the thermal conductive adhesive.

4. Filling

Pour the mixed and defoaming thermal silicone into a suitable mold and cut according to the desired shape.

5. Curing

Place the filled mold in an appropriate environment for curing treatment, so that the thermal conductive silicone gel has good mechanical and thermal conductivity properties.

The Smida planetary centrifugal mixer synchronously removes bubbles during the stirring process.

The above 5 steps are the conventional steps for thermal conductive silicone, and Smida's planetary centrifugal mixer is mainly used in the second and third steps. Mixing and vacuuming are carried out simultaneously, forming in one step, and the thermal conductive silicone can be mixed evenly in seconds to minutes.

Compared to traditional mixing methods, planetary centrifugal mixers can save a lot of time and synchronously remove bubbles during mixing, without the need for further operation. This can also save a lot of time. Overall, using planetary centrifugal mixers to mix heat transfer plate materials can save a lot of time and is very convenient to operate.
