Embodiment 1
[0087] refer to Figure 1-5 , a plastic shell structure, including a plastic shell 10, a PET composite decorative film 20 attached to the inner surface of the plastic shell 10, the side of the PET composite decorative film that is bonded to the plastic shell is a bonding surface , the side of the PET composite decorative film away from the plastic shell is a decorative surface; the decorative surface of the PET composite decorative film 20 is provided with an LDS antenna 30 . The area of the decorative surface of the PET composite decorative film 20 except the LDS antenna contact is also injection-molded with a plastic shell functional structure 40 for electronic products. A ring sealing structure 50 is also provided on the outer periphery of the plastic shell structure.
[0088] refer to Figure 6-13 , a method for preparing a plastic shell structure, comprising the following steps:
[0089] 1) Plastic shell preparation steps: provide a plastic shell;
Embodiment approach
[0090] In the step of preparing the plastic shell in this embodiment, as a preferred implementation, the manufacturing method of the plastic shell is as follows:
[0091] Injection molding steps: refer to Figure 6 , install the compression injection mold on the compression injection molding machine, and perform compression injection molding. When molding, the cavity corresponding to the product on the mold is closed to 1.3-1.6 times the volume of the plastic product, and the volume of the plastic product is injected at 1.05 times -1.2 times. The plastic material to the cavity, and then use the compression function of the compression injection molding machine to squeeze the cavity through the clamping pressure of the injection molding machine for secondary mold closing, completely close the cavity to 100%, and squeeze the plastic raw material to fill the entire mold. cavity and pressurize the excess plastic raw material to the overflow port of the mold to obtain a molded plast...
Embodiment 2
[0166] The characteristic of this embodiment is: in the preparation step of the plastic shell, the plastic material is a modified high-fluidity plastic material mixed with high-hardness PC or high-hardness PMMA+PC.
[0167] Others are the same as in Example 1.
