To know how big or how small your part can be with injection molding, we think it’s best to know how the actual process works first. Because, if the process doesn’t seem manageable for you and your company, then it might be best to follow a different route to produce plastic parts.

With injection molding, all you have to do is design the mold and let the rest play out. Keep in mind that even though injection molding is quite simple, the designing behind the mold is much more complex. Once you have the finalized look, all you need is a small tube for the “injection” to take place and the machinery will take it from there.

Inside the small tube is where the magic happens. You’ll streamline plastic beads through it, where they’ll get heated and fed into the mold. From there, the metal mold will keep the beads in place until it’s “molding” and cooled enough to be released. Once the desired temperature is reached, both sides of the mold will separate and the plastic part within will be ejected and ready for packaging/selling.

Before getting knee-deep in the injection molding game, you’ll want to know what kind of pros and cons come with the process. Will you have limitations? Will your company excel beyond belief in certain areas compared to that of other areas? You have to know before you potentially make a mistake that your company won’t be able to recover from.

In this article, we’re not going to talk about ALL of the advantages and disadvantages. Instead, we’re going to focus on how big or how small your injection mold has to be/can be. Let’s get into it.

As with any design process, injection molding has its weaknesses and limitations, no matter how versatile it can be. Some things to consider include:
