    LSR OVER-MOLDING

    TYPE-C CHARGING PORT

    On October 4, 2022, local time, the European Parliament passed a bill with an overwhelming majority. The bill stipulates that from the end of 2024, all new portable smart devices must use the USB Type-C charging port; from 2026, USB Type-C will also become the standard port for laptop chargers. On October 25, 2022, Apple confirmed that it would comply with EU requirements and all smartphones would use the USB-C charging port from 2024. 

    From 2024, USB-C will become the universal standard for electronic devices in the EU. USB-C will serve as a universal port in the EU, allowing consumers to use any USB-C charger to charge any brand of device.

    PRODUCT PROCESSING

    Treatment before over molding 

    The treatment process before silicone encapsulation of metal parts is a rigorous and meticulous process, which is directly related to the quality, durability and service life of the final product. In order to ensure that the silicone can be firmly and evenly attached to the surface of the metal parts, we need to perform a series of treatments on the metal parts before encapsulation.

    Surface cleaning of metal parts
    First of all, surface cleaning of metal parts is a crucial step. Degreasers, ultrasonic cleaning or steam cleaning can be used. During the cleaning process, it is necessary to ensure that the cleaning agent does not react chemically with the metal parts to avoid damage to the metal parts.

    Roughen metal parts surface
    Secondly, it is also necessary to properly roughen the surface of the metal parts. If the surface smoothness of the metal parts is too high, it will make it difficult for silicone to adhere. This not only improves the adhesion between silicone and metal parts, but also makes the encapsulated products more beautiful.

    Chemical treatment
    Next, it is the chemical treatment stage. For some aluminum alloy materials, we may need to perform anodizing treatment to increase the thickness of the oxide film on its surface, thereby improving the adhesion of silicone.

    Select a suitable adhesive
    After completing the above surface treatment, we also need to select a suitable adhesive. The choice of adhesive directly affects the bonding strength between silicone and metal parts.
