If you’re designing plastic assemblies that need to be taken apart and reassembled, you already understand that standard plastic threads simply won’t cut it. But understanding why threaded inserts are not just beneficial, but actually critical requires looking at the fundamental material science challenges that plastics present for threaded connections.
Threaded Inserts
How Do Load Paths Affect the Performance of Threaded Inserts in Plastics?
When plastics engineers think about threaded inserts, the focus often goes straight to the insert itself, looking at attributes such as knurl pattern, installation method and material selection. But here’s what gets overlooked: the insert is only as good as the load path supporting it. A perfectly specified insert installed
How Does Thermal Cycling Affect Threaded Inserts in Automotive Plastics?
If you’re a plastics engineer working on automotive applications, thermal cycling is undoubtedly a four-letter word in your world. After all, it’s one of the most punishing environments your components will face. In addition, it places stress1 on not only your plastic and composite parts, but also places strain on
How Do Inserts Perform in Carbon Fiber Composites?
Carbon fiber reinforced polymers (CFRP) have transformed aerospace, automotive, and high-performance applications by delivering exceptional strength-to-weight ratios and fatigue resistance. But how do you create reliable threaded connections in a material that’s fundamentally different from the metals we’ve been fastening for over a century? Threaded inserts. However, their performance in
What Are the Key Differences Between Brass, Steel, and Plastic Threaded Inserts, and When Should You Use Each Material?
When purchasing threaded inserts for plastic assemblies, the material choice directly impacts performance, cost, and reliability. While we’ve litigated this topic before, we keep seeing additional interest in our data, we thought we might provide something a little easier to digest about threaded inserts. Brass absolutely dominates the market. We’re
Choosing the Correct Fastener for Composite Materials and Plastics
How to Select Fasteners that Match the Properties of Composites and Plastics Arguably, nothing has revolutionized technological advancement and product design in key industries over the last 75 years like plastics and composites. Advancements in plastic and composite assemblies have driven advancements in key arenas such as aerospace, automotive, medical,
Choosing the Best Threaded Insert Material: Brass, Steel, or Aluminum?
Threaded inserts are essential in any industry where strong connections are needed, enhancing durability, design flexibility, and load-bearing capacity. Now, the need for the threaded insert is unquestioned. The hard part is deciding the material for the insert. Why? It’s because there are pros and cons for every common threaded
How do threaded inserts help automakers meet CAFE standards?
How custom components can help enhance durability in automotive assemblies while helping achieve bigger goals like emission standards for automakers In 2024, the CAFE standards for passenger cars stand at 54.5 MPG and are set to increase at 2% year over year for model year 2027 through 2031. Those kinds
Why Are Threaded Inserts Essential in Household Appliances?
See how the use of exotic materials, plastics and high-stress parts made threaded inserts a vital partner in the Appliance Industry As we move further into the 2020s, every household appliance seems to get more and more complicated. However, one thing remains the same: the need for seemingly simple,
Why Steel Inserts or Aluminum Inserts might be a good alternative to Brass
Here at CFI, we’ve been working with components of all kinds for over three decades, including threaded inserts. Typically, inserts are made from brass, due to the material’s versatility thanks to its position in the material science Goldilocks zone of relative strength, cost, corrosion resistance, machinability, thermal conductivity, and lack
