The Top Impact-Resistant Thermoplastics for Injection Molding

A large parasol in a park made of an impact-resistant thermoplastic called polycarbonate.

Many plastic parts – such as construction materials, outdoor equipment, and prosthetics – must withstand high, repetitious impact and bear significant loads of force. Not using a material that has proven toughness can run the risk of your part breaking, resulting in severe or sometimes life-threatening consequences. Choosing an impact-resistant polymer means finding the right balance between toughness and pliability. We’re here to help you by highlighting the top-impact resistant thermoplastic for injection molding.

The Benefits of Engineering-Grade Resins in Plastic Injection Molding

A gloved hand holding a screw driver next to plastic electrical housing make with engineering-grade resins.

Mainstream polymers are versatile enough to perform a large number of applications. Still, sometimes custom or specially built molded parts – such as for medical and public safety industries – have requirements that some commodity plastics just can’t meet. If a part needs to stand up to harsh conditions such as chemicals and fire, often engineering-grade plastics are the most viable solution. To understand how the application of these special plastics can minimize failure risk and achieve unique specifications, let’s review engineering-grade resins in plastic injection molding.

We’ve come a long way since the Model T, transitioning away from heavy metal beams and brackets to lightweight yet durable plastics. Today, plastic parts support a wide variety of car functions, from the pedal and seat components to the powertrain and fuel system. There are several benefits to using plastics in car manufacturing, and skilled injection molders are well-versed in matching the right polymers to a car part’s performance needs. To discover just how useful this material can be, let’s review the benefits of plastic parts in the automotive industry.

There are a lot of things that go into making plastic parts. But the single biggest choice that will affect multiple categories of strength, price, flexibility, production speed, and even mold design during the project is the kind of plastic resin you pick for your production. It’s also a decision that needs to be made by the client, not the mold or part designer. All we can do is suggest plastics based on your needs. Today we’re here to provide you with some background on the four most popular thermoplastics and why they are so often used.
