Polyetheretherketone PEEK Part

When it comes to making polyetheretherketone PEEK part, we usually rely on three methods: machining, injection molding, and compression molding. Each one has its own setup and requirements.

Machining: This is where we take PEEK stock and cut or polish it on standard or CNC machines to get the parts we need. The key here is to pick the right cutting settings, use the right tools and coolant, keep the temperature in check, and clear away chips as we go. If we get those details right, we avoid issues like burnt surfaces, wrong sizes, or cracking—so the final polyetheretherketone PEEK product comes out consistent and reliable.

Injection Molding: Here, we melt the PEEK and inject it under high pressure into a mold using an injection molding machine. After it cools, the part is basically done. This method is great for large batches—even complex or high-precision pipes come out with accurate dimensions and a nice finish.

Compression Molding: With this one, we put PEEK powder or pellets into a mold, then apply heat and pressure to melt and shape it. It works well for small runs of complex parts, and the surface finish is usually pretty good. The downside is it can’t handle undercuts, the cycle time is longer, and the consistency isn’t quite as stable as injection molding.

Which method we choose really depends on what the customer wants the final product to look like. After all these years, we’ve gotten the hang of every process—so the PEEK polyetheretherketone parts we deliver always meets our customers’ expectations.

Product properties：

1.Good strength retention at high temperatures:

This stuff (PEEK) keeps its strength even when things get hot. Regular PEEK holds on to more than 70% of its strength at room temperature, even after being stuck at 150°C long-term. Need to go hotter? The version with 30% carbon fiber mixed in still puts up a fight, keeping a bending strength around 80MPa at a scorching 180°C.

It's also a champ at taking hits and repeated use. Pure PEEK can handle an impact resistance up to 10 kJ/m². There's an even tougher version that pushes past 15 kJ/m², leaving brittle engineering plastics in the dust. It's incredibly durable—even after being stressed 10 million times, it barely shows any wear and tear, losing less than 5% of its performance.

2.Takes the Heat Without Breaking a Sweat

Thanks to its super stable makeup, polyetheretherketone PEEK part doesn't mind the heat. It keeps its structure and strength at high temperatures. It's not just heat-resistant; it's also great against oxidation, so it won't swell or crack, even after long stretches in hot, oxygen-rich environments.

3.Puts Itself Out

PEEK is naturally flame-resistant. In thicknesses between 0.8 and 1.6 mm, it meets the top UL94 V-0 rating, meaning it can stop burning on its own without added chemicals. If you somehow force it to burn, it produces very little smoke and no nasty toxic fumes.

4.Stays in Shape

Polyetheretherketone PEEK product is strong and tough, so it's really resistant to "creep"—that slow bending or deforming that can happen under constant stress. When dealing with moving or dynamic loads, it's even better because it absorbs energy, which slows down any deformation.

5.Easy to Work With

You can make PEEK into all kinds of shapes. Need complex parts in large quantities? Injection molding works fast and efficiently. Or, if you need precise custom parts, you can just use standard workshop tools like lathes, milling machines, and drills. This flexibility makes it a great fit for all sorts of industries and products.

6.A Great Insulator

At room temperature, PEEK polyetheretherketone parts is a fantastic insulator with a volume resistivity as high as 10¹⁶ Ω·cm. This insulation property barely changes, even at 200°C or in high-frequency setups. That makes it perfect for insulation parts in electronics that get hot, like chip holders and connectors.
