Glue potting machine what we call A&B glue potting machine , double liquid potting machine or two-component glue potting machine . It is a fully automatic liquid controlling machine which can be sealed,fixed products with waterproof by dispensing , coating ,potting glue to the surface or internal of products . We normally use two-component glue . Glue potting machine can be worked on irregular graphics including dot , line ,arc , circle and so on . It is mainly use for adhesive , filling, coating and sealing .
Glue potting machine always use two-component liquid what we call AB glue . Glue A is main glue and glue B is curing liquid . Of course it is same with one-component . The most widely used glue in the market are epoxy, polyurethane, silicon and other glue with ratio on 1：1、2：1、5：1、4：3、10：1 .
1.Put A&B glue into A&B tanks , Tank A and B are with the function to assure glue in good condition .
2.It is use two metering pumps to precise gluing and make sure glue A&B dispense the corresponding weight evenly .
3. Mixing glue A&B evenly through mixed device and automatically positioning by editing the glue trajectory through corresponding mechanical hand.
4. It is setting the corresponding quantitative glue and program to realize automatically positioning to satisfy the glue process .

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 .
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 .
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 .
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 .
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 acetone . Make sure air dry and add filter between plant air pressure and valve .
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 .
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 or teflon needles
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 .
