Epoxy Adhesive Dispensing Systems 2 component ab dispensing filling machine 

Features and Benefits:
1, A system of metering, mixing and potting.
2, Accurate metering and even mixing helps to avoid possible waste of glue.
3, Shot size and positioning keep consistent, fast.
4, Good universality makes PGB-700DR suitable for applications of LED, electric and others glue potting needed.
5, Easy to program and operate.
6, Tally function, non-standard mode, primer mode, level alert, filter mode, liquid display device, preventing backflow device and other functional device.

Application:
Industry: Capacitor, power supply, transformer, ignition coil, reverse sensor, circuit board, electronic ballast, other electronic products,weighh sensor and LED products where glue potting demanded.



Glue:
Epoxy, silica gel, AB glue, PU and other glue which need matching

Common troubles and solutions

• 1.Glue dispenser always drops

  Drops always happened when valve closed . The reason may be low concentration of glue , big air-pressure or large diameter of needles.

  Narrow needles will effect the flow of the liquid and cause back pressure . It will lead to dropping when the valve closed . Too narrow needles will effect the drainage of air when valve start to work, but it can be solved if change suitable needles .

  Conical needles with less back pressure and liquid flow smoothly .

  It is better to drainage of the air advance or use no-foam glue or deaeration to avoid the air cause dropping after valve closed .

• 2.Glue dispensing not evenly

  The problem cause mainly because of the storage flow pressure tank or air pressure is not stable.

  Inlet pressure regulating table should be set lower 10-15psi than factory minimum pressure . The pressure in pressure tank should be set upper than the middle pressure of regulating table . It should be avoided to use the pressure lower than the middle pressure of regulating table .

  Control pressure of rubber valve at least higher than 60psi to assured glue evenly .

  We should check the glue output speed at last . The glue is uneven if the time less than 15/1000s , the output speed more longer , the glue dispensing will be more stable .

• 3.Slow flow velocity

  It should be changed the pipe from 1/4 to 3/8 if the flow velocity too slowly .

  The pipe is the shorter the better if no requirement .

• 4.Air in the fluid

  Excessive fluid pressure and short valve opening time may lead to the air infiltration liquid . We can use the conical needles and reduce fluid pressure .

• 5. Instant glue (quick adhesive) blocking in valve connector and pipes.

  This problem is caused by heavy moisture and recycle instant glue . We should make sure to use new instant glue and wash the pipes with dry . Make sure air dry and add filter between plant air pressure and valve .

• 6.UV glue (UV curing glue )

  Make sure to use black pipeline.

  Don't add new UV glue to old UV glue in pressure tank , we should drain off the old UV glue before pouring new UV glue into pressure tank because the UV glue will produce bubble after a period of time and lead to glue dispensing unevenly .

• 7.Needles

  Normally , it may cause air problem if the needle less than NO.20 . It is better to use large steel needles or conical needles to avoid to use winding needles 

• 8. Epoxy cleaning

  It is better to use storage pressure cylinder of methybenzene toluene to self-cleaning one time for each shift . The more frequently cleaning the better .
