2) Let adhesives come to room temperature before using;
3) Preheat(115℃,5 to 10 minutes) adhesives with aluminum foil label on it
or preheat it in the oven(with package, 100℃)
4) Please remove jam at the top and bottom after preheating;
5) Please clean all the components with IPA, and make sure the surface is dry and clean;
Dispensing
1)Control the temperature between 115~130 ℃ and air pressure under 6 Bar;
2)Please use the stainless steel needle as far as possible; 19~23# needle are recommended;
3)Please squeeze small amount of adhesive before installing needles.
4)Please make sure the length of needle which will be exposed on the heater is no more than 3mm.
If adhesives could not be squeezed in the condition of normal temperature between 115~130 ℃ and air pressure(under 6 Bar), please check accordingly:
1)Plastic needle nozzle melts because of high temperature;
2)Adhesives in needle nozzle cured;
3)There is colloidal particles in adhesives;
Assemblage
Please assemble components within 1 min after dispensing.
