Injection molding is a complex process with a number of “moving parts” — both figuratively and literally — that should be monitored during production. The process is versatile enough to be the manufacturing method of choice for a broad range of products, but unfortunately, it is rarely as simple as just building a mold and running it through an injection molding machine. Several factors inherent to the process can affect the quality of your end product, and should be monitored and measured as closely as possible in order to maintain the safety and integrity of your parts.
Failure of your injection molding part can prove to be one of the most costly production issues that you can encounter. Not only must you absorb the cost of rejected pieces, it’s likely that you’ll also need to adjust the design of your product to be more conducive to the plastic injection molding process. Aside from this additional R&D time and expenditure, this means new tooling costs as well. As the direct costs add up, your time to market is also drawn out longer and longer, creating a double-whammy to your bottom line.
We’ve talked before about how certain additives can be mixed with plastics to change their color and appearance. But plastic additives can also play a much broader role in every part of the plastic manufacturing and use cycle, modifying the creation, processing, form and function of plastics — going far beyond simply changing the color.
