PEEK injection molding can use conventional thermoplastic manufacturing equipment to process PEEK. Unfilled and filled grades are usually supplied in pellets, powders, or ultrafine powders. Pellets are usually recommended for manufacturing methods such as injection molding, extrusion, monofilament and wire wrapping. Powders are suitable for compression molding, while ultrafine powders are commonly used in coatings, composite prepregs, and compression molding.The general process of PEEK injection molding is as follows:
- Drying: Granular polymers generally absorb 0.5%w/w atmospheric moisture and for best results should be dried until the moisture is less than 0.02%w/w. The material can be dried in a circulating air oven for at least 3 hours at 150°C, or 2 hours at 160°C. If it is dried in a drying box, the thickness of the raw material in the tray should not exceed 25mm. and prevent contamination.
- Recycling: Leftovers can be recycled and injected into virgin materials. It is recommended that recycled materials without fillers should not exceed 30% of the total weight, and recycled mixtures containing fillers should not exceed 10% of the total weight.
- Thermal stability: If the equipment is shut down during the melting process and the polymer residence time does not exceed 1 hour, there is no obvious degradation of the material at a temperature of 360 °C. However, if the shutdown time exceeds 1 hour, the temperature of the barrel should be lowered to 340°C. At this temperature, the material can remain stable for several hours. The temperature of the barrel must be increased when manufacturing continues. If the shutdown time exceeds 3 hours, The barrel should be cleaned. You can use some materials that can maintain performance at 380 °C, such as polyethersulfone or polyetherimide, or low MFI polyethylene for cleaning.
- Injection machine: The melting point of the polymer is 343°C, which is suitable for traditional machines that can maintain the melt temperature at 360-400°C.
- Barrel capacity: Due to the high speed manufacturing temperature of PEEK polymers, the residence time of the material must be as short as possible. The ideal barrel capacity is 2-5 times the total shot weight.
- Nozzle and locking system: The melting point of the polymer is very high, if the temperature drops below 343°C, the melt will solidify quickly. Therefore, it is necessary to install a large enough heater at the nozzle to prevent the “injection cold material” from cooling down.

While we provide these highly skilled people with the best equipment and technology available, our experience has taught us the value of something more important. Information. We check all of the possible issues before the project is started. like what is the surface requirement? Any potential sink marks issue? Any visible part line or gate mark allowed or not? Etc, and list all of these possible issues and make a report to our customer with suggestions, we call this is DFM (design for manufacturability) report. This will save lots of time and prevent lots of potential issues, this is the most important point to ensure that we finally will get the best quality mold and part.
If you currently supplier did not make this report to you, please do ask them to make fully DFM report before starting to make the moulds, because the quality of the injection mould will directly cause the quality of injection moulded parts
