How Recycled Plastic Coasters Are Made

With Christmas around the corner, our list of coaster sets to make skyrockets, so we thought we'd show you exactly how we do it.

We get the mould preheating in the oven to warm it up. This is especially important in cold weather, as the plastic won't flow properly and might result in failed injections. With the mould heating, we can load the plastic into the barrel. This mould needs 130g of plastic flakes. All our plastic comes from donations and collections from our local area, mostly from schools, businesses and beach cleans.

7 minutes later and we can get the mould out of the oven (with gloves of course) and clamp it into the machine. Pulling the wheel forces the ram down and pushes the plastic into the mould. Once both cavities are full, we can immediately unbolt the mould and take the coasters out. They typically only need a little bit of trimming before they're ready to be stamped with the plastic type. These were HDPE ♻️2.

This is actually our second coaster mould. Our first was a lot simpler, but we wanted to add some custom engraving, small feet on the bottom and give them a nicer finish, which is why we shelled out for this new mould.

If you want to grab a set for yourself, or as a gift for someone, you can get them on our website where we have them available in 9 awesome colours: https://www.brothersmake.com/shop/p/c...
