molding pvc

Moldie molds PVC which is one of the cool things that it does. You may be thinking, what the hell is PVC and why do we mold it? PVC is a type of very cool and versatile plastic, making it possible for us to create all sorts of stuff — pipes, toys and even shoes. They are simply transforming long fibers and mounding it as PVC plastic to make other products that are ready to use. So it’s a super important process because a lot of things we depend on are PVC!

So we used following process to mold PVC. We start with tiny bits known as PVC pellets and heat them until they become liquid. The melting step is critical because it changes the solid pellets into a heavy, gooey liquid. After the PVC is completely melted, we pour the hot, melted PVC into a mold — a special tool that can be used to mold the melted PVC into a specific shape. So imagine the mold as a cupcake tin helping create the cupcake in the shape you want! Once we have poured the melted PVC into the mold, we need to allow it to cool. When it cools, it hardens to our desired shape. And finally when it is fully cool and solidified, we can open the mold and extract the new object we have made.

The PVC Molding Journey

Working with PVC has a little bit of a learning curve. The first step is to design and create the mold. This process can take a few weeks, as we want to ensure that it is made perfectly, so that the right shape is created. It has to be perfect, the design! Once the mold is ready, we put it in some heat, add PVC pellets to the mold and vacuum seal. This pouring phase lasts several hours, as we need to be careful not to rush it. After that, we let the PVC cool and harden, again verifying this every couple hours. What’s it like waiting for your cookies to bake? Once all that has cooled down, we unlock the mold and extract the new object. Wow! That’s a lot of work, but so exciting to watch the end product come together!
