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.
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.
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.
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).
Your satisfaction is our highest priority.
