Ada Color Dispensing Systems
Ada Color Dispensing systems are systems that pro vide automatic and precise dosing of liquid products prepared on the basis of prescriptions in Ink abd Paint industry. Dispensing systems are sometimes known as ‘Color Kitchen’ or ‘Color Mixing Machine’. However, ‘Tinting’ systems, which are especially used in con struction paints, are different from dispensing systems with their usage and working style. In tinting systems, mostly volumetric dosing is made and the desired col oring is done by dosing small amounts on the ready base products. As with the word meaning, Tinting is suitable for ‘light coloring’ operations. Dispensing systems, on the other hand, can gravimetrically dose larger quantities, and in most cases produces by dos ing the entire recipe into an empty container.
Main Components of the Dispensing Systems
Our Dispensing systems basically consist of the follow ing components.
Weighing system: In order to do gravimetric dosing, dispensing systems have industrial scales with high precision. Scale capacities are selected according to the capacity of finished product container.
Dosing valves: They have multi-stages and recircula tion system specific to dispensing systems for a pre cise dosing. There are dosing valves as much as the number of components in the system. They can be of different sizes for different capacities.
Pumps: Diaphragm air pumps are mostly used to transfer the liquid components to the dosing valves which are connected to the system. Apart from dos ing, they are also used for the recirculation of compo nents to ensure homogenization.
Control unit: There is an electropneumatic control system for operating all components of the dispensing system.
Software: A PC connected to the controller, contains the dispensing software. The software consists of a database and operator interface where information such as formulas, component information, production records are stored.
Working Principle: All components (color pastes, var nishes, bases, additives, etc.) included in the product recipes to be produced are connected to the dispens ing system. The product recipes (formulas) are entered to the database of the software. After that, all that needs to be done is for the operator to select the de sired formula from the software, enter the desired amount and place the empty container on the scale. The system will produce the desired amount of prod uct in a short time (average 2-4 minutes for 20 kg) by dosing all the components in the formula with a very high precision (mostly ±1 g).
Benefits of the Dispensing System
Quality: Today, in almost all sectors, although the competition is getting harder but the product quality expectations are constantly increasing. Deviations caused by operator errors in manually produced prod ucts cause inconsistent product quality. At this point, the use of the dispensing system becomes more im portant. Production with maximum precision ensures that the product quality always remains at the same level. In addition, since the records of all products produced and all raw materials used in the dispensing system are kept, an extremely detailed and easily ac cessible traceability is ensured.
Just in time production: Dispensing systems, especially when used at dealers and end-use points, ensure that the desired product is obtained only minutes after the product is needed. It gives the opportunity to produce as much as the desired amount on time, without be
ing affected by the prolongation of the supply times, especially due to the disruptions in logistics due to the pandemic.
Stock cost: Users of Dispensing systems can have an unlimited number of colors by stocking only color pastes and main components. In this way, they can get rid of stocking hundreds of different products and significantly reduce their product inventory costs.
Low waste: Since only the required amount can be produced from the dispensing system, the residual products are minimized. In addition, since all compo nents are used in a closed system and it can always be kept homogeneous, situations such as evaporation and crusting can be prevented and possible wastage is also reduced.
Usage Areas
Dispensing systems are mostly used for liquid inks. But it is suitable for all products used in coloring, such as automobile paints, coil coating, furniture paints and other industrial paints, artificial leather, textile dyes or liquid masterbatches. Apart from these, it can also be applied to all liquid products produced on a prescription basis. In fact, there are applications such as dosing only the additives to be added to the product, not to create the entire product. The ever-increasing raw material and labor costs have shortened the return on investment for automation in production. Dispensing
is also used in products that did not have an application area before, both for this reason and due to increased quality expectations.
As Kairos Makina, for about 8 years, our main goal has been to ensure that our customers, both in Turkey and abroad, have easy access to modern technology that will enable them to make high quality produc tions by producing Ada Color Dispensing systems. We always offer our customers products with innova tive solutions, all of which are developed within our company. In this context, we will have the opportu nity to present our newly developed Ada Color Dis pensing systems, which can use up to 24 components in a small body, have a modern user interface, and provide space and cost advantages, to our visitors at paintIstanbul&Turkcoat 2022.
