When evaluating options, the cost is always a critical factor.
4.1 Material Cost
Generally, POM is more cost-effective than PEEK. The price of raw PEEK material is significantly higher due to its processing complexity and the advanced properties it offers.
4.2 Processing Cost
Processing costs vary widely between the two. While POM is easier and quicker to process, leading to reduced machine time, PEEK requires specialized machinery and tooling to mitigate its hard nature.
4.3 Life-Cycle Cost
Although PEEK is initially more expensive, its durability and longevity may result in lower life-cycle costs, especially in applications where material replacement is frequent.
Choosing between POM and PEEK ultimately hinges on the specific requirements of your project. Here are some guiding questions that can lead to better decision-making:
