Year of construction: 2025, condition: new, DOLFİN- VDL series Drum (Spiral) parts washing machines are used particularly for the purpose of cleaning small parts that are manufactured in large quantities and in bulk. The materials that are poured from the inlet part of the spiral drum in the device are directed towards the outlet part of the drum with the spirals inside the drum. While the drum moves in its own axis according to the set rotation speed, it subjects its parts to, respectively, washing (degreasing), rinsing, passivation and drying processes (varies per the model). Since these processes are sequential and continuous, all processes are completed quickly and effectively within a single device. Full penetration is ensured by pressurized spraying and dipping effects in each section. It is a very functional model of us that is used particularly for washing the bolts, nuts, washers, or such small parts, fittings, nipples, couplers and fittings that are processed in CNC and automated machines in high quantities. Regardless of the metal type of the parts to be washed, they are fully compatible with steel, brass, aluminum copper or stainless steel materials. Since Dolfin Parts washing machines operate as closed loop, new water and new detergent are not used every time. While washing is performed for several times with the same tank, all the dirt remains in the washing cell. With this feature, it protects both nature and employees. Due to its high efficiency and performance, saves energy, water and labor. The device operates continuously in accordance with the values of the washing parameters that have been entered from the control panel before operation. Parts that come out of production in bulk can be loaded into our device in 3 different manners. 1. With Vibrating Loading Chamber, 2.With Lift Conveyor, 3. By coupling to our Customer's existing system, Do not hesitate to contact for more information. Hnjdpfsv S Dk Sex Afiju We produce for you with 40+ years of experience!

Year of construction: 2025, condition: new, DOLFIN-kbn2 series parts washing machines are used for the purpose of washing the parts, which are also larger in size and heavy, requiring rinsing, passivation or another process, particularly after washing. While it is desired to have no oil and other contaminants on the surface before assembly or packaging at the businesses and factories manufacturing parts in masses, it may also be necessary to remove the washing chemical used in the 1st stage from the surface of the part according to the utilization areas of the part. For this requirement, rinsing or a similar implementation in 2nd step is compulsory. Our KBN 2 series parts washing devices are special devices that contain more than one tank and/or bath. While the parts that are placed in the device are rotated on their own axis by means of the washing basket, pressurized detergent hot water is sprayed. With the pressure, temperature and chemical effect, all oil and contamination on the part is cleaned. After the washing process and following the direction of the washing chemical to its own tank, the rinsing operation starts in the 2nd tank. If desired, the 3rd tank can be added and another function is added after rinsing. Since Dolfin Parts washing machines operate as closed loop, new water and new detergent are not used every time. While washing is performed for several times with the same tank, all the dirt remains in the washing cell. With this feature, it protects both nature and employees. Due to its high efficiency and performance, saves energy, water and labor. The device automatically completes the loop in accordance with the values of the washing parameters that have been entered from the control panel before operation. All processes are carried out with specially prepared programs along with PLC. In order to load, particularly the heavy items into the washing basket or to remove them from the basket, the washing basket can be taken on a carrier trolley, in other words, from the device when required. It can be transferred to any point of the workshop with this trolley. We produce for you with 40+ years of experience! We export to more than 30+ countries with quality and trust.
