Mold for molding and processing a mobile device casing and applying molding processing to manufacture a mobile device casing Method

A mold for molding a mobile device casing and a method for forming a mobile device casing, in particular, a mold for molding a mobile device casing and a method for manufacturing a mobile device casing through the mold.

The current mobile devices such as handheld mobile phones and tablet PCs provide faster and faster computing power, and the relative heat generated by the internal devices of the mobile device is also higher, whether through the uniform temperature plate. Or the heat transfer potential of the heat pipe or the graphite sheet must guide the heat to the outside of the device for heat release. Some mobile device manufacturers use plastic or other non-metal materials to manufacture the casing of the handheld device for the appearance of the texture or the appearance of the mobile device.

It has been confirmed by experiments that the anti-heating of the handheld device still has a better heat dissipation effect for the metal casing, and the casing of the hand-held device for manufacturing the metal material mainly performs the cutting processing of the metal block through the CNC processing tool, thereby obtaining a thin metal. The outer casing, and the cutting or shuffling processing through the CNC processing machine, as the name implies, is to remove the unnecessary parts of the material by the material removal method, thereby obtaining the desired product, and it takes a considerable time to perform the cutting and material removal processing. , in turn, the increase in the cost of working hours, and the selection of the cutting tool and the loss of the tool during the cutting is also the processing cost A considerable amount of problems.

Furthermore, the purchase of CNC processing equipment is the most important cost in production, because multi-axis CNC machining tools are much more expensive than other CNC machining tools, and the operator must write the machining program and the knowledge of operating CNC machining tools. Therefore, the training operator is also another personnel cost to be considered. The multi-axis CNC machining tool is quite sophisticated and complicated, and the maintenance cost is also high.

In addition, CNC machining tools must use a large amount of scraping agent to cool down during the cutting process, and some of the scraping agents can not be recycled and recycled, which will cause pollution to the environment.

Therefore, how to improve the process and thus save manufacturing costs is the goal of the person to be improved.

There are also attempts by the manufacturer to manufacture a hand-held device casing by a stamping process, but the inability to extract and return material for a relatively complicated structure such as a structural design having rounded corners or curved surfaces cannot be overcome.

At this stage, the plastic casing is still manufactured by injection molding, or the metal casing is processed by CNC processing equipment as the mainstream of the process. However, if a metal casing having both texture and better heat dissipation performance is desired, how to improve the process can greatly reduce the manufacturing cost. The primary focus of the people who want to improve.
