The multi-sump type ultrasonic precision cleaner has been developed especially for large-scale cleaning operations or high-grade precision cleaning operations.
It is ideal for precision-machine items like automotive high-tech components(Injector,Auto-Lock Brake System, Booster etc), electronics parts, optical elements.
Besides the versatility and efficiency of multi-sump cleaners, this automatic machine has a high-quality cleaning finsh and easy operation profile.
Even in maintenance cleaning there is sometimes need for automation because of heavy work pieces etc.
Main advantages of automation
Effective cleaning operation for forced production tempo
Effective connection of material flow to loading and unloading ends of the cleaning machine
Uniform quality-no "Monday quality" effect
Easy and safe handling of heavy goods
Safe handling of expensive or sensitive goods
Savings in labor cost
Avoiding workers to be exposed to chemicals
Standard System Features
All Daehan SP(super precision) series aqueous cleaning systems come with the following standard features:
• Automated transport
Multi-Basket Handling System simultaneously conveys tray shuttle.
• Stainless steel construction
To improve corrosion resistance, all tanks, frame are constructed of annealed 316 stainless steel.
• R/O water system
To meet contamination requirements of customer, we normally use deionized water.
• Communication Modem
To communicate with customer's own shop floor system for getting a data of production amount, trouble time, we have communication modem.

SUMMARY OF OPERATION
•The transport system simultaneously conveys multiple shuttle through the cleaning system in a parallel manner to increase production.
•The shuttles are immersed in a heated R/O water and detergent and rotated.
•After the 1st & 2nd washing process, the shuttle is rinsed with R/O pure water. At that time, the shuttle is rotated in the ultrasonic main tank.(3×Rinse)
•A blast of fine compressed air blows water droplets after the final rinse.
•After the blow-off, compressed hot air blowing is done for drying, then to cooling for good handling.
•The operation of washing, rinsing, air blowing, hot blowing and cooling are done at the same time by simultaneous loading system.
•From the 1st stage to the final cooling process, the shuttles are always rotated for high quality of super precision washing.
Individual Standard Features
ㆍWASH AND RINSE
The wash and rinse portions of the process consist of a immersion wash station and a 3-stage recycling rinse station.
• Ultrasonic
all tank uses piezoelectric immersible transducer which is located on the tank bottom.
• R/O water system
deionized water is used in all tank.
• Tray shuttle rotation
For better cleaning effect, tray shuttles are rotated in the tank.
• Recirculation system
a centrifugal pump, cartridge filters, pressure gages, flow control valves are consisted of recirculating system.
• Temperature control
All tanks are equipped with heaters to be able to maintain the preset temperature of the each tank, independently.
• Liquid level control
Automatically, water level is controlled by a solenoid valve from the DI water supply when level is low or high.
• Sub tank
The sub tank is divided into two area as dirty zone and clean zone.
AIR BLOWING
•A blast of compressed & regulated air removes large water droplets.
•The direction of nozzle can be easily adjusted.
•For better blowoff, tray shuttle is rotated.
•The fine filter(0.01miron)was installed.
HOT AIR BLOWING
•The compressed air is heated up to 120 degrees.
•The direction of nozzle can be easily adjusted.
•For better blowoff, tray shuttle is rotated.
•The fine filter(0.01miron)was installed.
•Temperature control
•electric heaters maintain preset temperature of dryer chamber.
COOLING
•The filtered and compressed air cools down the temperature of the parts for good handling.
•The fine filter(0.01miron)was installed.
TRANSPORT SYSTEM
•Shuttles are moved from tank to tank on Multi-Handling System.
•It means that all the tanks are kept simultaneously occupied.
•Thus the required cycle time can be easily reached.
•Cantilever design, with friction surfaces below and behind tanks
•Acceleration/deceleration without oscillation and variable speed
•Simplified programming
•Crash protection
•Exact positioning for vertical and horizontal position
APPLICATION
•Aqueous cleaning is the best choice for fine precision application.
•Typical applications for SP series are as follows:
•Fuel injector components
•Brake parts
•Booster parts
•Precision metal components
•Optics
•Electromechanical components
