Polypropylene is one of the most common plastics used worldwide. In fact, it’s second only to polyethylene in volume. Despite being such a commonly used material, however, it’s still important for engineers and entrepreneurs alike to understand polypropylene plastic: its properties, its uses and even a bit of its history. In addition to being broadly found in full-production manufacturing, polypropylene is well suited for prototyping. Understanding more about the material will help you learn why.
The injection molding process is one that, although the baseline concept is simple, involves a number of intricate facets and moving parts (both literally and figuratively). The number of settings, calibrations, sub-processes, and choices that can be made or changed — even minimally — can have major effects on the finished product. Those effects include its quality, appearance and the time it takes to make it — among many others. What’s more, each of those aspects plays a part in another major component of a product — its cost and, by extension, its bottom line.
Material selection is a key factor for many aspects of your injection molded part or product. It affects some or all of the following, in most cases: the physical properties of the product, its look, its operation, its interaction with other materials and components, and its durability. On top of all that, material selection can play a big role in your material and production costs, and their subsequent effects on your bottom line. Taking all of those factors into consideration, it’s clear that choosing a material for your injection molded product should not be taken lightly.
