How Our Phone Cases Are Made

A phone case is an absolute necessity in today's world. We take our phones with us everywhere we go which leaves them increasingly vulnerable to damage. This is where a protective phone case comes in to safeguard your device. While we all use cases, most of us don't know how they are made. Let's take a closer look at how our phone cases are made for a new insight.

Our polycarbonate cases are made using a special machine that is custom designed and called an injection mold. The machine is typically made with a mold based created from chromium steel bars which merge together into a block while applying pressure. A mold make is also used to shape the mold base into the desired size and shape. The mold will also have holes drilled into it for the addition of cooling fluids. This helps the case harden before being removed from the mold. From there, the polycarbonate is left to dry and then smoothed and polished.

TPU cases are made in a similar fashion to polycarbonate cases, but with a few differences. For starters, the machine is a compression mold machine. This process involves using pre-heated TPU material in an open, heated mold. The mold is then closed and pressure applied until the TPU takes the desired shape and size of the case. These cases typically take longer to make since it requires a lot of pressure for an extend span of time to ensure the product does not lose its shape. Once the TPU is shaped, the case is removed from the mold and trimmed of excess material.

What about dual layer cases with both TPU inserts and a polycarbonate shell? Most cases made in this design are two separate pieces which are made in their respective machines using the right mold to account for this fact. The pieces are made separately and then put together once completed before shipping. In the cases where the pieces are not separate, they are usually molded separately and then brought together for a final mold in a specialty machine for the task.
