The world's mobile phone waterproof war, what kind of waves will be caused by liquid silicone?
First, the global "waterproof war" of mobile phones started
In the increasingly fierce market competition, mobile phone manufacturing companies have set their sights on waterproof mobile phones. The speed of enterprises' deployment of waterproof mobile phones is accelerating, and the "waterproof war" has begun in the world.

According to reports, in 2015, the waterproof function will become a standard configuration for Sony's mid-range mobile phones, and Sony's partners have developed waterproof models according to Sony's requirements.
Shipment of waterproof smartphones will increase by 20-30% in the next two years. Waterproof mobile phones will begin to spread and become one of the basic functions of mobile phones.
Second, the advantages of liquid silica gel and production process introduction
Liquid silicone rubber, abbreviated as LSR, is a thermosetting material with good fluidity. Currently widely used in consumer electronics, health products, automobiles, waterproof supplies, kitchen appliances and seals.

1Advantage
The traditional 3C product waterproof technology usually uses glue bonding, ultrasonic welding and other methods to set a silicone waterproof ring or use plastic and TPU two-color molding to achieve the waterproof function at the groove / rib position of the plastic structural part. However, this method requires manual operation in the middle, its assembly accuracy and stability cannot be guaranteed, and the waterproof effect is poor.

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

1) Performance advantage

   Liquid silica gel with its good thermal stability, cold resistance, electrical insulation properties and no toxic substances during combustion.

2) Process advantages

   Simplified waterproof structure, more compact overall structure

 Improved assembly accuracy and repeatability, and improved waterproof effect

   Reduced silicone ring assembly process, reducing costs

   Waterproof silicone ring and battery cover have high bonding strength, which can be disassembled multiple times

2.Production Process
The application of liquid silicone on the precision structural parts of mobile phones is a process that has emerged in recent years. The choice of the process can be achieved by using self-adhesive silicone or ordinary silicone + primer coating according to the product structure. Improve the yield rate in production.

Forming equipment

There are two types of liquid silicone injection molding equipment: vertical and horizontal. The machine's parameter configuration is adjusted according to different product structures and functional requirements, so there will be differences in mold structure, capacity and production cost.
