Visual Position Epoxy Dispensing Systems for Potting Resin for Electronics
Automatic glue filling machines are essential tools for the automatic proportioning and real-time filling of two-component AB glue, with ratios ranging from 1:1 to 10:1. These machines, such as the Liquid Dispenser Machine for AB Potting Compound, are commonly used in industries like LED lamp manufacturing, power modules, sensors, and transformers, where precision and efficiency are crucial.
Electronics are increasingly present in our lives, these technologies all use a wide array of components -sensors, actuators,central processing units (CPUs), printed circuit boards (PCB), electronics components , Capacitor, power supply, transformer,ignition coil, reverse sensor, circuit board, filter products ,underwater parts, electronic ballast ,aviation parts, aerospace parts....etc. - that need to be protected against environmental factors such as dust and moisture, as well as fluids and heat andfire exposure.
Our 2 component application equipment is the the good machine for potting and encapsulating vary parts and products, which apply different production processes required metering , mixing , dosing , dispensing and potting with high accuracy and high efficiency.
Potting 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.
We offer automatic ,se-mi automatic fluid dispensing potting machine and the related production line and vacuuming systems .
Main Technologies
Overview of Glue Dispensing Machines
A glue dispensing machine, also known as an AB glue dispensing machine, automates the process of filling products with glue. These machines feature glue dispensing systems designed for automatic proportioning, quantitative filling, and circulation management, ensuring products achieve optimal sealing, fixing, and waterproofing. This automated operation resolves issues related to low efficiency and poor quality in traditional methods, significantly reducing labor costs and enhancing productivity and product quality.
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 Suitable for 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

The glue dispensing epoxy resin dispensing machines offer high cost-effectiveness, with a single device capable of replacing 2 to 5 workers, enabling a return on investment within six months.
| Function | Introduction | Usage Advantages |
| Automatic Material Supplying | Automatically supply the materials according to the set ratio, and filling it to the mixing tank with constant speed and flow-ability | Compare to the traditional manually material preparation, saving more labor-cost, convenient operation, keep working environment neat , clean and the filling amount is more accurately. |
| Dynamic Mixing | Automatically dynamic mixing the A&B compounds, high speed mixing and good sealing ability to avoid air bubbles | Timing quantitative, dynamic mixing and using in one machine, no need to do the vacuum additionally, saving labor costs, convenient operation, improve production. Dispensing to products directly after stirring and degas, make the most use of ab mixture before it's solidified. |
| Timed Quantitative Filling |
Set up and save the settings programs for one serious of product, the setting can be invoked for future usage. The dispensing volume, speed can be adjusted freely in software system. |
Dispensing volume more accurately and productive. The potted products will be more homogeneously , surface flat and good quality. |
| Low Liquid level Alarming System |
When the material in tank is not enough or the machine, the machine will show the warning signal to remind re-filling. | Humanized engineering design, avoid the serious damages with fool-proof settings. |
| Dripping-proof Function |
When the dispensing head needs to move accurately, and finished the potting process. The moment resorption function will start and make sure the glue won't drop off to dirty the products or working table. | To avoid the glue to pollute work table or effect the outlook of the products. |
| Timing- Dispensing (self-discharging function) |
According to different glue features, users can set up the dispensing output speed and interval time to avoid the glue cured in the mixing tube. | To avoid the glue cured in the mixing tube while workers short-break and shift switching . |
| AB Bucket Sealing (AB tank sealing) |
There's a professional sealing rings to make sure the AB tank in good vacuum status around 48 hours per time . | To avoid the sensitive material especially the hardener of PU to be crystallization . |
| Cleaning Function |
Clean and wash the A&B valve automatically. | Convenient, fast, clean. Dynamic mixing to avoid the machine was stuck by AB mixture |
| Automatic Stirring Function |
Can auto stirring the filler materials, to avoid the sedimentation. | To avoid the the sediment of the AB materials to block the mixing tube, and make sure the glue ratio mixing equalization and quality and reduce the waste, keep the working environment clean, and improve the production. |
| Heating Function |
Preheat materials in tank , pump and pipes to assure constantly temperature . | Make sure the materials warm, movable and potting quality |
