However, charger have more smaller size, the heat dissipation problem when charging the mobile phone is new challenges for various manufacturers.
There are charger products safety standards for safety reasons. An important indicator specifically implemented in the charger cases is the fire rating.
The general safety standard is UL94-VX currently. The plastic material around the sock pin must meet the UL94-V0 fire rating in the US and Europe. The plastic materials that meet this fire rating is high cost, in order to reduce production costs, factory use the tone molding process currently to produce the mobile phone charger.
According to the three-plate mold design, Switek use a five-axis servo robot in this solution, the main arm completes the embedding of semi-finished products and the removal of the case of the finished mobile phone charger, and the auxiliary arm completes the removal of the runner.
In order to maintain the appearance of the stock pin no scratches, we do not use the vibration plate discharge system commonly used in in-mold insertion, but people place it carefully to minimize damage.
