the heating temperature setting
date:2013/8/268
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.
