The traditional waterproof technology of 3C products is usually by means of gluing, ultrasonic welding, etc., in the groove/rib position of the plastic structural parts, setting the silicone waterproof ring or using the plastic and TPU two-color molding method to realize the waterproof function. However, since this method requires manual operation in the middle, the accuracy and stability of the assembly cannot be guaranteed, and the waterproof effect is poor.

At present, silicone is widely used in electronic products as a waterproof material. Let's take a look at the advantages of liquid silicone?

1) Performance advantage

  Liquid silica gel has good thermal stability, cold resistance, electrical insulation properties and no toxic substances when burned.

2) Process advantage

  The waterproof structure is simplified and the overall structure is more compact

3) The assembly accuracy and repeatability are improved, and the waterproof effect is improved

  Reduce the assembly process of the silicone ring and reduce the cost

  The waterproof silicone ring and the battery cover have high bonding strength and can be disassembled and assembled many times.
