In general, in the method for processing the base 6 of the present invention, two molds are used to complete the processing, one of the molds may have a lower processing accuracy, and the other mold may have a higher processing accuracy. The base 6 of the utility model is completed as a whole by two steps:

step one, the processed metal sheet 8 is placed in a first base mold, and a first material is injected into the first base mold to form a first semi-finished product.

Wherein the first base mold may be a less precise mold and the first semi-finished product may comprise only the bottom plate 61 portion of the base 6. At this time, the first portion of the embedded metal sheet 8 is embedded and fixed into the chassis 6.

And step two, moving the first semi-finished product into a second base mold, and performing injection molding on the first material or the second material into the second base mold to form a base 6.

The utility model also relates to a second embodiment of a method for machining the base 6, comprising the following steps:

step one is the same as the first embodiment, and is not described again.

Step two, different from the first embodiment, the step two welds the electronic component 7 to the second portion 82 of the semi-finished product of the step one, and then injects the first material or the second material into the second base mold to form the base 6.

It is understood that in the second embodiment, since the electronic component 7 is already fixedly connected to the component connection terminal 8211, no through hole is required for the second injection molding.

In summary, the utility model aims at the defects of the prior art, the second part 82 embedded with the metal sheet 8 is used for replacing the FPC board, and the base 6 is generated by two times of injection molding, because the materials and the molds used by the two times of injection molding are different, the second set of mold has high precision, the overall shapes of the first part 81 and the second part 82 are not changed after the injection molding, the position deviation caused by potential energy generated by the material of the FPC board is avoided, the product precision and quality can be greatly improved, and the utility model has wide application prospect and extremely high commercial utilization value.
