What is Plastic Injection Molding?

In short, plastic injection mold design is a process that creates molds for a variety of different products. Each mold starts as a design created by a computer. The design is then converted into a series of instructions that the machinery can follow. The machinery melts the plastic, injects it into a mold, and then cools the plastic down to set it in place. The resulting molded pieces are then cleaned, inspected, and assembled into finished products. The entire process takes place inside a large machine known as an injection molding machine. Each part of the process is critical. If the design isn’t correct, then the mold or finished product could be flawed.

Why Use Plastic Injection Molding to Make Custom Chocolate Molds?

Plastic injection molding is one of the most efficient ways to create molds for a variety of products. The process is highly customizable and can be used to create molds of almost any shape or size. In fact, almost any product you can think of has likely been made using injection molding. Plastic molds have been used to create everything from automobiles to microwaves.  You might think that creating your own custom chocolate molds from scratch would be an expensive and time-consuming process. But in reality, a custom injection mould manufacturer allows you to manufacture your own custom molds at a fraction of the cost.

Which type of plastic is best for making molds?

Plastic is plastic, right? Well, it turns out there are different types of plastic that are better suited to making molds than others. In general, you will want to select a plastic that’s sturdy but not brittle. If your mold is too brittle, then it will break when you try to remove the chocolate. Molded chocolate can be a bit messy, so you’ll want to select a plastic that’s easy to clean. You’ll also want to make sure that the plastic won’t break down in the chocolate or in the environment it will be sitting in. For these reasons, high-density polyethylene (HDPE) is often the plastic of choice for creating molds for chocolate. It’s sturdy but flexible, cleans up easily, and it won’t degrade over time like some other plastics might.

How much does it cost to make custom molds with plastic injection molding?

The cost of creating cheap plastic injection mold will vary from company to company, so it’s difficult to say exactly how much it will cost you to make your own molds. However, you can get a general idea of how much it costs by comparing it to other ways of creating custom molds. Let’s say that you have a small business that makes chocolate bars and you’ve decided that you want to make your own molds rather than purchasing pre-made molds. The first option is to have a custom mold created by a mold shop. These shops will use a variety of different methods, such as CNC milling and injection molding, to create your mold. Generally speaking, you can expect to pay anywhere from $4,000 to $20,000 for a custom mold. If you want to use injection molding to create your molds, you can expect to pay roughly $5,000 per mold. You’ll also need to factor in the cost of raw materials.


Plastic injection molding is a great way to create your own custom chocolate molds. It’s efficient, customizable, and can make molds of any shape or size. It can also be very cost-effective when compared to other methods of creating molds. You’ll just need to make sure that your design is correct and can be applied to all sides of the mold. In the end, though, the benefits of using injection molding to create your own custom chocolate molds far outweigh the downsides.
