Electric Driven Two Component AB Epoxy PU Silicone Dispensing Equipment
Two component AB Epoxy PU Silicones Gluing Machine
1)Machine details:
2)AB potting machine is composed of Five Systems:
- Automatic material-feeding system
- High precision pump metering system
- Dynamic/Static mixing system
- Three-axis motion system
- Programming control system.
AB-component materials flows into the pump through the feeding system (AB tanks) separately by the self-suction force of the metering pump.
3)Features&Functions:
Strong versatility / Multiple configuration / High production capacity / High precision
- Auto feeding : take use of vacuum pressure to feed materials into A&B tank separately.
- Tank Stirring : A and B tank configure with stirring motors and blades to prevent material sediment in the tank bottom .
- Heating : Tank , pipe , pumps are optional with heaters to assure the whole system can be heating from room temperature to 90°C adjustable.
- Vacuum : A &B tank vacuum for degas the bubble inside material .
- Dynamic mixing : Configuring dynamic motor and mixer to mix A and B fluids evenly.
4)Advantages:
1,Accurated metering and even mixing helps to avoid the waste of material.
2,Dispensing volume and positioning keep machine work consistent and fast.
3,Good universality
4,Easy to program and operate.
5,Tally function, non-standard mode, primer mode, level alert, filter mode, liquid display device, preventing back-flow device and other functional device.

6)Electronic Appliances
7)Suitable Material
Two component potting materials , 2-part compound materials, AB part compound materials , 2K silicones ,2K epoxies resin, Bi-component PU, Ployerster, Polyurethane, UV materials and so on .
8)Machine description and working principle
Compound materials A & B are kept in two tanks separately. There are two sets of metering pumps inside the machine for metering A and B resin by setting ratio, draining out material individually from tank A & B. Liquid A & B mix with each other in the mixer pipe and dispensed out according to the programmable data.
Guangzhou Daheng Automation Equipment CO., Ltd is specialized in the R&D and sale of glue metering, mixing and dispensing machinery.
We believe in "the creation improves future". Core technology is the only true creation. The e core of all the liquid controlling device is its metering and mixing system. Daheng, always taking its continuous efforts in the new technology, new products and new working process, created its unique tech "double- cylinder pump", which is a liquid control system of high precision, changeable, continuous and long span time, and can be applied with glues of different viscosity. The core technology makes us the first pioneer in the gluing machine industry which passed CE certificate, SGS. We have over 20 patents, many original products and many "first" in the industry.
Including the standard machines we already have, we also accept customized services. We,headed in Guangzhou, and branched in Zhongshan, Shenzhen, Shanghai, and exported into Russia, Turkey, Netherland, Singapore, Indonesia and so on.
We provide the on-going train-up for customers, 24 hours x 7 days service, and keep ourselves being improved on and on.
The current and great development of Daheng depends on your support and trust. We will keep ourselves making long effort in the industry and products. We will keep improved in the cylinder pump and precision valve, and keep the leading among our competitors.
Common troubles and solutions
The most common trouble of glue dispenser is the valve . We list the effective solutions as follow:- 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 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 .
