a, so stay in the barrel and screw the screw rotation chilled molten plastic in order to facilitate and provide molten plastic to obtain the necessary part of the heat;
b, set the temperature lower than the melt 5 \ '10 ℃ ​​(provided in part by the friction heat);
c, the adjustment of the nozzle temperature can also be used to control salivation, condensed material (plug Tsui), pull wire and other issues;
d, crystalline plastics are generally temperature control:

Note: a, do not add more to the non-glass fiber reinforced plastic.

b, the barrel melt temperature is usually higher than the tube outside the control of the temperature.
