Plastic Injection Molding Material Selection: How To Pick The Best For Your Medical Device Production
Plastic injection molding is a very cost-effective method for mass production of parts – but even the best designs sometimes have shortcomings that result in quality defects. It is important to be familiar with these defects in order to identify and trouble-shoot them, as well as avoid them by developing a competent design! Below are the top 5 most common quality defects in injection molding and how each can be resolved. Additionally, for more information on these and other types of cosmetic defects see the glossary that was compiled by The Society of Plastics Industry.
OEMs have a significant challenge to manage: achieving production volumes while maintaining high levels of quality and minimizing cost. From an injection molding perspective, mold design and equipment selection play a big role in determining whether these goals are achieved. One key equipment decision for OEMs is their mold cavitation strategy as it directly impacts cost, quality, lead times, and speed of production.
If you’re designing a plastic part, there are a lot of considerations to think about from a manufacturability standpoint. Having Mold Flow simulation software watching your back ensures your original design has the best practices in mind. From simple flow simulations to complex quality predicting, warp analysis, fill analysis, weld lines, pressure, temperature and gate location, utilizing some type of mold flow simulation will save you a lot of time in your product development process.
When developing a medical injection molding process with repeatability as the cornerstone, does it really matter how you get there? Every medical injection molding supplier has their own internal validation process, but when you pull back the curtain and dig into the details as to how it was developed there might be some issues that arise.

There are endless reasons as to why an OEM will choose to change their medial injection molding supplier or think to change. The main 6 categories that we often see as the culprit are:
