Problems in PEEK injection molding
Thread Content
I’d like to ask the experts: What causes PEEK injection-molded products to become brittle?
Please describe in detail: what grade of PEEK is used for injection molding? Injection molding temperature, pressure, and your product structure? Should recycled material be used? Additionally, the injection-molded PEEK products are brittle. What’s the reason for this? Was this discovered during experiments or upon injection molding? After describing the details clearly, we can proceed with the analysis.
Is the temperature too high, causing decomposition?
Also, is recycled material being used?
When you say “brittle”, do you mean it’s more brittle compared to existing standard parts? The mechanical properties of PEEK products are determined by the crystallization process at the molecular level. The phenomenon you described is rather vague; thus, it’s impossible to determine the cause of the problem
