   Why Choose Us

High Accuracy Polyurethane Glue Dispenser Automatic Metering, Mixing, Potting Machine for LED Lighting and PCBA
We specialize in different types of potting and dispensing system. No matter what your resin application requirements look like:
we can do most of them in our fully equipped lab. We can handle 1- and 2-component polyurethanes, epoxies, acrylics, silicones,temperature, humidity and UV curing materials. They can be from low- to high-viscosity, filled or unfilled and even high abrasive for thermal conductivity.

Potting and encapsulation is the process of embedding products & assemblies in a liquid resin (potting compounds) to protect them against rough environment conditions. Potting can be performed in atmosphere pressure or even under vacuum, if high voltage insulation and high temperature differences are needed. Encapsulation of parts will stop corrosion of metals and reduce damage caused by vibration and mechanical stress.

Product Description

Description of the machine

PGB-700 ab dosing dispensing machine precisely metering, mixing and dispensing two-component medium to low-viscosity materials for potting, dispensing ,sealing, casting ,encapsulation and filling.
For variable ratio dispensing, the system handles ratios from 1:1 to 10:1.
The system is composed of AB tanks, metering pumps and motor, mixing pipe, dual valve, dynamic motor for dynamic stirring and 3-axis robotic platform. Two kinds of component materials are separately before they mix in mixing tube to avoid glue cure in system. Dispensing valve is with suck-back function to keep thin fluid from dripping.

Introduction :

1. Working Mode: controlled by PLC module and MCGS touch screen.
2.High precision valve: high speed, glue off clean, no glue drawing, no dropping. 3. Core metering pump specially design for different material from low to high viscosities.
4. Mix glue A & B more evenly; no more or no less for agent B.

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.

Tank system technology:

1. Stainless panel vacuum pressure tank which can bear negative pressure of inner tank . 2. Tank with motor stirrer that prevent the glue from sediment and keep the potting material in constant temperature.
3 Tank with top/ high /low liquid sensors that ensure alarm warning when liquid higher or lower the setting level .
4 Tank with vacuum degas (degas time can be set through touch screen), so the material can be re-feeding through vacuum negative pressure .
5 Tank with pressure releasing ball valve ; the bottom of tank reserved back-flow connector and river closure ball valve.
6 Tank with heater which can preheat materials to assure good flowability .
7 Tank with artificial feeding mouth that can be added glue appropriately by hand . 8 Tank with silica-dryer which can prevent material especially PU from crystallization .

 

D&H Pump technology
1. Two cylinder plunger pumps work by durable motors. 2.The biggest flow volume :24g/s,Repetition accuracy:0.2g.
3.Also Suitablefor high viscosity glue: 50cps~35000cps.
4. Suitable for big flow dispensing or slight flow dispensing.
5. Suitable for frequent start and stop dispensing.
6. Anti-wear, Anti-corrosion, super long life time.

 

Valve technology

1. Dynamic mixing with stirring detecting function that ensure glue mixing evenly .
2 Stainless design of the glue touch surface to capture more higher material compatibility .
3 Glue valve with flow-back prevent function that can prevent glue from dropping when stop gluing .
4 Sealing parts of rod shaft adopt imported parts to keep more higher durability .
5 The self-cleaning function make machine cleaning more easier that you needn't dis-assembly the parts to wash . Cleaning time and cleaning times could be set in the touch screen.

FAQ

Do you offer oversea service?
We do not have overseas service center,but we can offer oversea service if customer required, engineer will offer face to face service.

How dose your factory do regarding quality control? 
We assure 1 year warranty for the main part,also we offer spare part for back up.Please check with sales engineer in detail.

What are your payment terms?
Normally, 30% advance by T/T and balance paid off before delivery.

Are you a factory or trading company ?

We are a factory with SGS certified and more than 20 patents,and cooperate with different customers  coverd about 40 countries for over 15 years.

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 .

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 .

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 .

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 .

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

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 .
