How It’s Made: The Ins and Outs of Injection Molding [VIDEO]

A while back, we started a blog and video series all about the imprint process. These “How It’s Done” videos showed just how logos and business names got put onto the products we love. We featured several imprint methods and showed how hats got embroidered, how leather luggage is debossed, how stress balls get pad printed, and just about every other way a logo joins with its promotional product soulmate.

After we helped all of our readers become experts on just how logos applied to their favorite promo products, we started thinking, “Wait, how did these water bottles get here to begin with? Where do pill cases begin before we ever get around to putting logos on them?”

As it turns out, our customizable line of promotional products are built and assembled like any good product (and not, sadly, grown in an orchard of ready-to-imprint goodies). The process is called injection molding, and it involves heat, tubes, machines, and the dedicated operators who make sure it all goes smoothly.

Ready to watch it happen right before your eyes? Without further ado, here’s the story of how a plastic promotional product is born!


Ah, the magic of plastics! Who knew that each reusable water bottle (and all its plastic friends) was once nothing more than a collection of small plastic beads. Apply heat (and just a touch of technology), and voilà! A fully grown promotional product, ready to get imprinted and move out into the great, wide world. They grow up so fast.

If you’re ready to see more action-packed videos, like how promotional products get imprinted with your snazzy logo, you can catch it all here on our blog. You can also check out our YouTube channel, which is committed to bringing you steady stream of hilarious videos and promotional product magic.

    I mean… how awesome are our videos! They make me feel more knowledgeable and I crack up every time! Our Media Team is hilarious!
    On another note: How cool is that! I never had any idea of what it takes to make a plastic water bottle… Now I do! Seems like a straight forward process but I’m sure it is a ton of more work than how easy it looks in the video! Those are some high tech pieces of machinery! Just thinking of all the little plastic Items we have on our website blows my mind that all of them are created using this same process! Pretty cool! All that hard work to imprint your logo on a cool Premium! It makes me appreciate all the hard work people put into these Items. It is really amazing to see the process each Item goes through to get created and get in your hands for a minimal amount of money! Great video guys as always! Keep up the great work! Go Team QLP!

    Wow, how cool is that! The media team outdid themselves yet again. There is so much more to promotional products than an imprint. It all starts with a quality item being shaped and produced to order. It is insane to think about all the work that goes into producing the item itself before it is even ready to be imprinted with all the logos that awesome come through. I had no idea that water bottles started out so small and were actually formed to order! The machinery that is used to produce just one item is unbelievable! I guess I always thought that factories just had stock in an item and printed directly on them. Now that I do understand the process of producing a single item and the handwork that goes into, it does make me appreciate my end of the promotional product industry! The people that do make these items to order deserve some major props! Thanks again team for the awesome video! Super informative and definitely an eye opener to how many of our items are produced!

    There are several processes of moulding plastic to transform it into useable shapes; each method has its own benefits and requires specific expertise and skill to execute. But i believe the injection moulding process is one of the most widely used
