FULLY AUTOMATED DISPENSERS
Fully Automated Dispensers:
With more than 50 years of experience in the cast polyurethane industry and by employing state-of-the-art computer and instrumentation technology, we have developed a polyurethane metering and mixing machine that consistently delivers quality cast elastomers.
StateMix urethane dispensers can be set up easily and are capable of metering and mixing various polymers such as MDI, TDI, and rotational casting systems.
The heart of our innovative design is the interaction of Coriolis mass flow meters and precision metering pumps with digital motor drives, all of which are monitored and controlled by the main computer.
By connecting these instruments and taking advantage of the latest technology in networking systems, we have designed and manufactured a reliable and rugged dispenser with impressive accuracy.
Since almost all components of our system are off-the-shelf products, maintenance and upkeep of this machine are greatly simplified and made more economical.
Each fully automated dispenser is designed and manufactured to meet each client’s specific needs and requirements.
Pump Assembly
The pump assemblies in the StateMix dispenser consist of a positive displacement pump and a DC motor. Our pumps are carefully selected off-the-shelf products, which provide uniform, pulseless flow under varying conditions of pressure, temperature, and viscosity. By using different pump sizes, total flow rates of 0.1lbs to 200lbs (100kg) per minute are achieved.
Each DC motor is connected to its own motor drive and each motor drive continuously receives updated information from its mass flow meter and adjusts the pump speed to maintain the set flow rates.
Mixing Head
Our dynamic mixing heads are designed with ease of operation and simplicity of maintenance in mind.
Up to 6 streams, including flush and dye, can be introduced to the mix head simultaneously. We have taken steps to minimize the number of moving parts, seals, and bearings in the mixing head.
HMI Controller
The main computer is also an off-the-shelf industrial processor that provides an operator interface while monitoring and controlling all main functions of the system. To begin the pour, all the operator has to do is enter the desired ratio and total flow rate. From this point, the computer will take over, calculate the flow rate of each individual component, start the pumps, and establish the feedback loop between mass flow meters and the motor drive while all streams are being re-circulated to their respective tanks.
Coriolis Mass Flow Meters
Coriolis mass flow meters are the most accurate sensors in the industry, regardless of viscosity, temperature, or density of the material.
Each stream in our fully automated dispenser uses a Coriolis mass flow meter, enabling our dispensers to have an extremely accurate flow of material.
Independent Dye Streams
Up to 3 independent dye streams can easily be incorporated into our fully automated dispenser.
Each dye stream delivers the colours directly into the mixing chamber and the dye compounds can be added to each individual recipe.
Tanks and Heating Chambers
All tanks are individually heated with their own air- or electric-driven agitators. Our tanks vary in size from 5 to 110 gallons (20 to 440 liters). The heating system on each tank consists of a multiple number of low wattage heating coils wrapped around the tank, providing consistent heating of the material inside the tank. All lines, valves, manifolds, pumps and mass flow meters are in enclosed insulated chambers and heated by forced air and controlled by separate PID temperature controllers. Temperature ranges from room temperature to 260°F (130°C).
Frequently Asked Questions
What air pressure should I have on the dispenser?
Minimum of 100psi.
What nitrogen pressure should be on each tank?
There should be between 5-10 PSI. NOTE: Pressure cannot exceed 15 PSI due to pressure safety valve on each tank.
My pressure reading is very high when I turn on the pump?
Make sure material is up to temperature, make sure all valve in cabinet are open for forward and return lines.
I can circulate but when I pour my pressure goes way up and material does not seem like it is coming out.
Check to see if air is turned on, make sure the injector knob is not closed, remove injector and check for buildup of material at injector port. if air lines were removed make sure they are reinstalled the right way.
What kind of cleaner should I use?
Benzoflex or dibestic ester
I have material coming out of carbide area what do I do?
if using a hose on mixing nozzle, reduce flow and check pressure on pressure transducer read out display. If no hose is on nozzle check nozzle for buildup of material, remove carbide and inspect carbide O-ring and carbide for cracks.
Pumps start to race up.
Check material level, check forward valve is opened, check filter is not plugged. make sure nitrogen is on tanks.
Air leaking from air solenoid at top of boom
injector lip seal may have flipped. If air is coming out when not pouring forward seal may have flipped. Remove the black air line from solenoid one at time, check to see if air is coming out. If yes trace hose back to injector and remove the air line at the injector, if air is coming out then replace seals. if not, inspect other air lines until found.
I can not get any flow on my MOCA line.
- Verify timer to make sure machine came on early enough for material to melt.
- Verify temperatures were set correctly and if not heat up material to desired temperature. If those fail, then verify that fuses are not blown.
- Verify Heat trace to ensure it is heating the hose.
- Verify that the filter at the pump is not clogged with material.
