It can reliably protect sensitive circuits and components for a long time within a wide range of temperature and humidity changes. It has excellent electrical insulation properties, can withstand environmental pollution, and avoid damage to products caused by environmental factors such as stress, vibration, and humidity. The main ingredients are generally silicone resin, polyurethane resin, epoxy resin, etc., which have excellent thermal conductivity and bonding properties.

[0003] When processing thermal conductive potting glue, the raw materials need to be mixed after proportioning. During the mixing, there will be agglomerated particles in the raw materials. When the raw materials are mixed in a sol-like proportion, the stirring roller may not be able to break up the internal agglomerates, resulting in particles in the mixed glue and incomplete mixing.

[0010] Furthermore, the top surfaces of the bottom plates under the mixing sub-barrel and the mixing barrel are both fixed with servo cylinders, and auxiliary push plates are both fixed to the output ends of the servo cylinders, and the top edges of the two auxiliary push plates are both set to be arc-shaped.

[0011] Furthermore, the diameter of the mixing sub-barrel is the same as the diameter of the mixing barrel, and the opposite ends of the mixing barrel and the mixing sub-barrel are both configured as cones with opposite tips.
