When it comes to injection molding, a common request we receive is advice on the right plastics to use in their projects. While we can only provide suggestions, one common point of confusion for our clients is the difference between thermoplastic and thermoset resins. As part of the injection process, both plastics are subjected to heat during the process, and it is in this difference (which you may have guessed to the thermo prefix) that truly separates these two types of plastics and give them their unique qualities.

The great thing about working with plastics is there are many to choose from for their different characteristics, abilities, composition, durability, price-points, and more. These can range from plastics that is as hard as metal to plastics that are designed to flex when molded properly as a living hinge. From this wide array of plastics, let’s look at one of the most common types of plastic used: ABS plastic, and why you can find it in everything from drainage pipes to LEGO bricks.

Over the past century, the plastics industry has saturated our world and drastically changed the way we live. Today there are high-strength polymers that can meet and even exceed metals in terms of strength and flexibility. This has had a transformative effect on parts manufacturing, allowing metal parts to be swapped out for plastic parts that provide the same structure, but with reduced weight, more design flexibility, more efficiency, and less cost. If you want to take advantage of these changes with an existing part, it’s time to look at a metal-to-plastic conversion for the component.

The injection molding process is the most commonly used manufacturing process for the fabrication of plastic parts in the world. It is so popular because of its ability to create a wide variety of items of differing sizes, shapes, and complexities. Most injection molding machines use the same process – thermoplastic conversion – to turn the plastic stock into the final molded parts, using these five basic steps: [Read more…] about Five Steps of the Thermoplastic Conversion Process
Thermoplastic injection molding is the most common way to manufacture parts. Thermoplastics are polymers that can be repeatedly molten or softened by heating and solidified by cooling—as a physical change rather than a chemical change that takes place during the creation of thermoset materials. It is important to distinguish what type of thermoplastic should be used for the type of product you want us to help you create. Below are the most common thermoplastics used in injection molding.
