The 3 Common Mistakes in Designing Products for Injection Molding

White plastic spur gears interconnected in black, plastic housing designed through plastic injection molding.

Injection molding is the most common manufacturing process, and businesses are eager to start projects using affordable and durable polymers. However, due to the intricacies involved in plastic injection molding, engineers need to carefully consider how they design their parts to ensure maximum part performance and reduced tooling costs. When a business’s engineers take it upon themselves to make an injection mold without the consultation of injection molding specialists, errors are sure to arise. Let’s review three of the common mistakes in designing products for injection molding.

How Prototype Tooling in Injection Molding Accelerates Production

Two bottle-shaped plastic injection molds laying side by side meant to demonstrate prototype tooling in injection molding.

Many believe prototyping is just an extra, unnecessary step in the injection molding process, which is a misconception that can result in severe production line disruptions and forfeiture of time and money. In fact, some believe it increases costs and inhibits development and production times, but in reality, it does the opposite. Proceeding with a custom injection molding without prototyping often results in a series of tool adjustments that can become both time-consuming and expensive. Let’s review precisely how prototype tooling in injection molding accelerates production and saves you time and money.

Rapid Part Prototyping: Why to Include Manufacturers During Design

The act of prototyping is typically performed to test various part designs to create the best product, and sometimes it’s required to show multiple design elements to prospective investors. Regardless, prototype development is integral to the plastic injection molding process, as the final product should mirror the designer’s image. However, there are often time constraints on part manufacturing, so individually prototyping different molds can be wasteful. That’s where rapid part prototyping comes in to play.
