Resin applicator machine
Daheng AB Potting machine helps AB compounds offer superior protection potting to igniters and electronics.
Daheng Universal equipment is widely works for epoxies, silicones and polyurethane compounds , we configure different functions for the features of different compound to meet up with the production purposes .
Epoxies, silicones and polyurethane are among the most frequently used potting compounds. These can be applied to igniters ,Ignition Coiols ,PCBs,PCBA,capacitors,power electronics, LED lighting, sensors, and more. Some of the desired properties include good adhesion,excellent electrical insulation, thermal stability, super chemical resistance, low shrinkage upon curing, an appropriate coefficient of thermal expansion (CTE), and suitable viscosity for the specific application. Formulations can be blended to provide a balance of these and other properties through selection of resin, agent, and fillers.
Epoxies, silicones and polyurethane are commonly used with fillers to lower shrinkage, enhance dimension stability, and improve abrasion resistance. The use of fillers is the critical factor for obtaining thermal conductivity while retaining electrical resistance.
Besides ,the liquid potting material must flow easily so that it completely covers the component, leaving no voids. If air becomes trapped in the housing, the moisture it contains may cause corrosion - eventually leading to component or product failure.
Daheng equipment with pre-heat functions that helps the pre-heat the AB compound in tank in advance to keep a good flow-ability.Good liquidity helps resin flow into product easily and evenly.
Daheng machine with tank stirring vacuum degas functions ,which can help compounds to remove air bubble easily and arrived the good potting status .
Removing air bubbles is very important.Vacuum degassing remains a critical processing step. The best technique for vacuum degassing is referred to as "bumping degas" which is alternately pulling and relaxing a vacuum in 30- to 60-second cycles.
More details picture as follow :
Machine configuration :
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 :
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 Patented plunger 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 .
