PA46 Processing Temperature as High as 290-330°C
Problem Phenomenon
The processing temperature of PA46 is as high as 290-330°C, and the barrel and screw heat resistance of conventional '2079851475616104452 machines is insufficient
Cause Analysis
The melting point of PA46 is 295°C, and the processing temperature needs to be 290-330°C, while the upper limit of conventional '2079851475616104452 machines is about 300°C
The heating band power of the barrel is insufficient to reach 330°C
The precision of the thermocouple and temperature control system is insufficient
The heat resistance of the screw and barrel materials is not enough
The nozzle and mold runner require special heat-resistant design
Solution
Use a high-temperature special '2079851475616104452 machine with a barrel that can reach 350°C
Replace with high-power heating bands
Use a high-precision temperature control system
Select high-temperature-resistant screw and barrel materials
Use heat-resistant steel for the nozzle and runner
Key Takeaway
PA46 requires ultra-high temperature special equipment
