Why Choose Us

High Accuracy Polyurethane Glue Dispenser for LED Lighting industry

High Accuracy Polyurethane Glue Dispenser Automatic Metering, Mixing, Potting Machine for LED Lighting and PCBA

We Daheng Automation 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.

We offer automatic ,se-mi automatic fluid dispensing potting machine and the related production line and vacuuming systems .2K potting technology AB glue dispensing machine Epoxy dispensing machine Two-component dispensing machine,Dual-component dispensing machine Meter-mix dispensing machine,Resin dispensing machine Adhesive dispensing system,Dispensing robot with high precision Dispensing valve, Liquid dispenser , Automated dispensing equipment

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.

PLC Operation Controlling System

1 Dispensing volume is controlled by the speed of pump’s motors ; Glue speed adjustable within the speed range .

2 Machine with detecting function that detect the speed and running time of pumps to ensure the ratio reliability.

3 Adjustable gluing-out volume make sure glue A/B dispense out at the same time from glue valve to get better glue mixing effect .

4 Machine with gel resistance calculator , which prevent the mixture curing inside .

5 You can set single gluing-out and steady gluing-out function to meet up with your different process requirement .

6 Whole machine system and function is controlled by Panasonic PLC and MGCS touch screen .

7 Reserved PLC communication interface, which easy connecting with outside device .

8 Equipped with a safety lock to prevent staff from wrong operation .
