One of the main advantages of using injection-molded components is versatility in the plastics available for specific, often complex, applications.
Addressing plastics needs early in the design process is ideal, as is partnering with an experienced custom injection molder with plastics-specific expertise. Working together ensures the plastics have the characteristics needed for the job, and that materials-based complications will not arise during design and molding.
When choosing plastics you have to give equal weight to product end use, moldability, and performance throughout the injection molding process. Your injection molding partner's expertise in plastics and Design for Manufacturability (DfM) analysis is imperative in guiding you through key considerations, such as:
For instance, if your plastic component will be continuously exposed to the extreme heat of a tooling or cutting operation, you might choose polyether ether ketone (PEEK).
In working with expert custom injection molding engineers to identify the complexities of the project design, tooling, and molding, you may discover design changes are needed so PEEK performs to project expectations. Since PEEK is not as fluid as other plastics, its behavior during the injection molding process needs to be taken into account in the component design.
This illustration demonstrates how plastics selection impacts all aspects of an industrial project, and how quickly a seemingly good solution could add unanticipated expense, bias outcome, or completely derail a project.
Understandably, cost is a factor in plastics selection. However, making it the sole focus could be detrimental to part functionality and longevity — which could lead to time-consuming injection molding process rework, warranty claims, litigation, and irreparable harm to your brand and reputation.
Finding the appropriate plastics at the appropriate price point — without jeopardizing part performance — is best accomplished with the help of an experienced custom injection molder. Their plastics expertise lends itself to understanding general cost ranges and the plastics that fall into each category, such as these examples:
