Plastic molding methods are nothing new. In fact, as far back as 1872, a man named Hyatt registered a patent for a machine which injected molded plastic. Today, the industry has come a long way and thanks to modern technology, methods like in mold decoration are possible. Here is more about the process and some of the many benefits it has to offer.

How it Works

Suppose you want to manufacture cell phone covers or remote controls for electronic devices. You could injection mold the cases and covers and then apply adhesive stickers to them for the numbers, and function keys. However, these stickers may soon wear off, and then the items become difficult to use. Instead of stickers, you can use in mold decoration for a more permanent solution.

The basic principle plastic part decorating uses layers of dried paint and resin which transfer to the plastic part. After the mold closes, the machine injects the coloring onto the part. It does it in a specific pre-programmed manner. This takes sophisticated machinery for the job. It also takes special molds designed for the operation. After the decorating is complete, the labeled part gets cleaned, and the entire process is usually fully automated.


You can imprint high-quality clear graphics and images on your plastic parts. Intricate designs are easily accomplished, and this is visually impressive. You may print your design or graphics on many types of materials. For example, it works well for flat, curved, and multi-sided parts.


In mold decoration is a very efficient method. For example, you do not have to use consumable supplies like labels, ink, or adhesive. The entire process gets done in one step, so you have very fast production times. You enjoy a wide range of designs and colors and can easily customize your labeling.
