Plastic injection molding offers nearly unparalleled versatility and quality in manufacturing. The ubiquitous nature of the process means that it’s rarely a challenge to find an injection molding manufacturing partner, whether for tooling or for the process itself — another quality that makes injection molding a popular choice for products (though finding the right manufacturing partner is a different story). The cost of a plastic injection mold can, however, often stop entrepreneurs and engineers in their tracks as they experience a bit of “sticker shock,” especially if they’re unfamiliar with the process
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.
Material selection plays a huge role in injection molding for your product invention or prototype, affecting nearly every aspect of your part. Review the common materials used for injection molding.
