Plastic bottom cover is design to stick with silicone sealing ring by 3M tape at the 1st version, after the metal insert screw installing, the sealing is easily fall off, the sealing effect is not well. The latest design is changing to PC cover over molding with LSR sealing ring, reduce the production cost and improve the sealing function a lot!
PC&LSR over molding water toothpick tube design is iterated from glue sticking. In the old design, PC hard plastic part and LSR geometry are produced individually, two geometries are sticked with glue, which is easily fall off. The bonding is highly improved by over molding, so is the production efficiency.
Traditional processing to produce Type C Port is dispensing, sealing ring is made by heat compressing silicone rubber. The new processing nowadays is liquid silicone rubber over molding with anodizing metal insert, which improves the sealing function.
Fox Mold produce various kinds of smart phone liquid silicone rubber waterproof stopper, plug, jack and lid.
And smart phone liquid silicone rubber waterproof USB charging jack sealing.
And smart phone liquid silicone rubber waterproof USB charging jack sealing.

Over-molding sensor is also widely used in consumer electrics. The special feature of this kind of connector is that it usually contained hard plastic, soft plastic and pins, in this case the hard plastic is SPS-GF30, soft plastic is liquid silicone rubber.
Our customers are often faced with a challenge: how to over molding liquid silicone rubber parts with hard plastic with glass fiber, but ensuring the bonding is good, will not separate with heat or other extremely condition.

The Injection Molding Process Follows
Injection molding is a flexible, consistent and cost-effective manufacturing process that can quickly produce parts in a variety of materials. Once the process is set up and tested, the machine can produce thousands of injection molds items per hour.
Firstly, polymer pellets are dried and placed in a hopper, then mixed with coloring pigments or other reinforcing additives.
The pellets are fed into the barrel, where they are simultaneously heated, mixed, and moved toward the mold by a variable pitch screw. The screw and barrel geometry are optimized to help build pressure to the correct level and melt the material.
The piston moves forward and the molten plastic is injected into the mold through a runner system which filling the entire cavity. As the material cools down, it re-solidifies and takes the shape of the mold.
Finally, the mold opens and the now solid injection mold parts is pushed out by ejector pins. The mold then closes and the process repeats.
