Problems solved by technology
In the traditional technology, after injection molding of the USB connection hole, it is easy to form overflowing glue and burrs on the bottom plane of the hole. Due to process problems, the margin left at the rounded corner will be larger than that of the straight edge. Ordinary cutting schemes will leave burrs on the bottom edge of the hole. Difficult to remove burrs, dry ice or manual removal will increase production costs

Abstract
The invention relates to a processing method for an electronic product shell. The processing method comprises the following steps: providing an injection-molded metal plastic part and a fixing jig, one end part of the metal plastic part is provided with a connecting hole, and the connecting hole has a linear side and an arc side; the metal plastic part is fixed on the fixing jig; the connecting hole in the metal plastic part is roughed, and one end, close to the internal of the metal plastic part, of the connecting hole is provided with an annular boss to obtain a semi-finished shell; and theconnecting hole of the semi-finished shell is finished, and the annular boss on the connecting hole is milled off from the linear side of the connecting hole to obtain the finished shell. The processing method for the electronic product shell has the advantages of simple processing steps, realization of uniform surrounding chipping allowance of the connecting hole through the finishing, realization of uniform force bearing in a cutter, uniform material falling and effective removal of burrs at the edges of the connecting hole through milling off the annular boss from the linear side, production cost saving and improvement of the production benefit.
Description
technical field [0001] The invention relates to the technical field of material processing, in particular to a processing method for an electronic product housing. Background technique [0002] With the development of the economy, more and more electronic product casings are made of metal, such as mobile phones, tablet computers, etc. The casings made of metal materials have exquisite appearance, good wear resistance, and are not easy to scratch and fade. By the majority of consumers love. [0003] During the processing, various connection holes, such as USB connection holes, etc. are often required to be processed on the metal shell. Since electronic products such as mobile terminals have built-in signal lines, the signal lines in the all-metal shell will be affected by the shielding of the metal shell, so it needs to be injected on the USB connection hole to reduce the impact of external factors on signal transmission. In the traditional technology, after injection moldi...
