So you've designed a product. You've gone through the RFQ process, sharing your CAD drawings with engineers who probably made even more tweaks. The part is going to be made of plastic using the injection molding process. But you've never made a plastic injected part before. There are a lot of new words and phrases being tossed around and you don't really know what they all mean.
Runner Sprue? Water Baffle? Ejector Pin?
Is a tool the same thing as a mold? Why is mold spelled two ways (mold vs. mould)?
And how does the whole thing actually work?
No one would blame you for looking for a glossary of terms right about now. Fear not. One of my colleagues put together a Slideshare that breaks down the components of an injection mold in simple, easy-to-understand language. It even includes labeled cutaway drawings. I promise, if you didn't understand how an injection mold worked before seeing this slideshow, you will afterward.
Take a look (you'll need to double click on those opposite facing arrows at the bottom right to enlarge the screen):
Pretty simple, right? If you're up for an even deeper dive in the world of plastic injection molding, check out this video from a previous blog post that complements the Slideshare. In it, one of our capable engineers explains the ins and outs of injection molding (Get it? Ins and outs?) The video is about 12 minutes long, and packed with great information.
