3 Tips for Overcoming the Limitations of Plastic Injection Molding

Every modern manufacturing method has its strengths and its weaknesses. 3D printing may be fast and relatively cheap, making it great for prototyping, but it cannot be scaled up for mass production. CNC milling can produce complex parts out of very hard materials but at a high cost. There are limitations of plastic injection molding as well, but there are also ways to offset many of these weaknesses with a little foresight, especially when working with the right vendor early in the process. Learn our top three tips for getting your parts made with injection molding the right way.

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.

Injection molding is the preferred method for producing high-quality plastic parts, but it’s a complex operation that requires extensive knowledge of the process and machinery. That’s why it’s important to consider various aspects of a part’s designs, as everything from the vendor’s qualifications and equipment and to the part’s angles and edges can influence the quality of the final product. The subsequent guidelines to follow when designing injection molding parts require more upfront work but will pay dividends in both mold design and part production.

Every business needs to prototype and test their products before they go to market, but this is especially true for startup companies building their flagship products. Your first products can make or break your company and having prototypes, and injection molding for startups gives you the flexability to start early with short-runs and prototyping. Regardless of your revenue source, from venture capital to crowdsourcing, the sooner you can make physical copies of your product, the better.

Design for Manufacturing: Working Early with Vendors

Computer with CAD graphic design on it.

For many businesses, looking for a parts manufacturing vendor happens late into the design process, often after you’re deep into the design phase. This has its advantages, as the scope of the product has already been figured out and having a CAD or physical prototype allows for quicker mold design. However, it’s not usually the right decision when it comes to the end product. Work with your vendor early in the design process, even before prototype development, can result in a product that’s easier and less costly to manufacture, with fewer mold design and injection molding production problems.
