The main consideration of the Carbon fiber reinforced PEEK material molding
PEEK is a kind of special polymer materials, has excellent physical and chemical properties, and is a class of semi-crystalline material. Carbon fiber reinforced PEEK is the most common modified material, what consideration should be taken in the molding?
1. Molding machine
It is recommended to use injection molding machine with closed-loop control function.
2. Screw type
The material of the screw should be withstood 400 degrees Celsius, because the heating temperature of carbon fiber reinforced PEEK is nearly degrees Celsius, and it is necessary to use a low compression ratio screw without a stopper.
3. Material drying
Drying equipment should reach a drying temperature of 120 degrees, and the drying temperature can maintain a drying time of about 6 hours.
4. Operation
The PEEK molding process should be controlled by screw speed and position, which ensures injection rate and filling time, Injection time, pressure and temperature control are the three key parameters to monitor.
5. Clean
After the injection molding is complete, the screw can be cleaned using plastic material with thermal properties exceeding 370 degrees. PEEK should not be left in the molding machine.
Due to the excellent performance, PEEK is increasingly used in high-tech fields, which also requires suppliers to pay attention to the processing to ensure the project proceeds stably
