At Jaycon Systems, we love working on hands-on projects, from hardware prototyping and CNC machining to 3D printing and resin casting. These technologies and techniques allow us to quickly prototype so we can identify any design flaws before moving on to a more expensive method of prototyping. The beauty of techniques like resin casting is that we are able to duplicate prototypes quickly and inexpensively. All we need is some patience throughout the process. In this tutorial, we will teach you how to duplicate a plastic part; whatever your reasons are to duplicate it, we hope you find this useful!

Do you ever need spare plastic parts, or need to replace a broken or worn part, such as a plastic cap or a door bell switch? Do you ever want to make multiples of a favorite model, like model car parts, or change something from a foam/clay design to a plastic component? These can all be done by resin casting, which is to make a mold of the desired item and then pour plastic resin into that mold.

While it’s easier to write about, it’s actually a little more time-consuming in real life and there are many steps to the process. The desired item must be prepared for the mold, the mold and the resin for the part must be poured, and the final part must be cleaned for best results.

The following are the items that are needed to produce a plastic piece:
