PEEK Plastic Machining: Why Entrust to the Experts

PEEK plastic machining
PEEK is one of the best high-performance plastics on the market, with a unique combination of outstanding properties that make it incredibly strong and dimensionally stable both under load and in the harshest environments. It is also one of the most expensive polymers available. At a cost of $4,500 per pound, PEEK is 5 to 8 times more expensive than other high-end polymers. So when it comes to PEEK plastic machining, it is important to choose an experienced company who can avoid waste and meet your specifications.


Although PEEK is expensive, material cost is only one factor to consider when manufacturing a part. PEEK offers long-term savings due to its durability, strength, and high temperature resistance, outperforming and outlasting other polymers. PEEK’s superior properties include:

Other benefits of PEEK include:

PEEK is also available in a variety of grades that offer enhanced benefits.

PEEK Plastic Machining vs. Molding

When it comes to manufacturing parts from PEEK plastic, machining is a better method than injection molding. Because of PEEK’s high temperature resistance and high tensile strength, it machines more like a metal than a polymer. This makes injection molding a difficult and costly process. Injection molding tools are expensive and time consuming to make, and they can only produce a few hundred PEEK parts before having to be replaced. Additionally, if PEEK is not annealed properly, different areas of the material will react differently to the stress being placed by the tool. This causes cracks to develop and the dimensional stability of a batch of components can vary significantly.

In its solid state, however, PEEK is readily machinable by CNC milling machines. PEEK plastic machining is the preferred option in most high precision applications, especially when the components need to deliver excellent mechanical and wear properties.
