When cutting plastic processing, a spike or flake of material, called a “burr,” is left behind. Usually, the drawings are almost always “burr-free” or describe a post-process called chamfering, which removes burrs as a post-process to prevent harm to the workers who use the part. This deburring process can cause a lot of time to be spent on the deburring process, even though the machining process does not take much time. It would be better if burrs could be removed by machining, but in many cases this is a manual process, so it is also a good idea to design parts where burrs do not affect the product so much when it is used to shorten the delivery time.
The final process involves applying double-sided tape to the plastic, and there are two ways to do this: one is to apply the tape in one piece and the other is to apply it partially. In the one-piece process, a die is made to apply the tape, while the partial method of applying the double-sided tape leads to a shorter delivery time.
