The Pioneer of Viscosity Controller
VISCON viscosity controller is making use of characteristics of diaphragm pump.
If liquid viscosity increase, pulsation of diaphragm decrease.
If liquid viscosity decrease, pulsation of diaphragm pump increase.
Flow of Viscosity control
１．Circulate target desired viscosity ink.
２．Pressure switch check pulsation of diaphragm pump of viscosity controller.
Pulsation is converted to cup second. Converted cup second is displayed as viscosity value
Pic. A Viscosity value 15.5
Set value 15.5
３．During gravure printing and coating, viscosity increase 0.1 cup second.
４．Pic. B Viscosity value 15.6
Set value 15.5
５．Solvent supply （1 time or several times）
６．Pic. C Viscosity value 15.5
Set value 15.5
Can keep target desired viscosity 15.5 cup second.
Repeating above A → B → C → A, viscosity controller can keep maintaining
Target desired viscosity.
Viscosity increase - Gravure printing
in 20 minutes Viscosity increase 1 cup second (Japan)
in 10 minutes Viscosity increase 1 cup second (South East Asia)
1. Red color area of above table
a. Waste of ink (higher viscosity ink than target desired ink)
b. Create printing problems, such as doctor line, ink transfer, white dots etc.
2. Blue color area of above table
a. Waste of solvent
b. Create problem, such as destroy ink structure.
3. If viscosity control done by manual, viscosity change happen from 3 to 7 cup second
During gravure printing. ( refer to red color area and blue color are in above table.)
It leads to color difference of printing.
4. If viscosity control by viscosity controller, viscosity can be controlled within ±1 cup
second. Color difference will not happen.
5. If use viscosity controller, users can save about 15% of ink consumption.
- High precision
Professional design and processing to ensure the high precision working, +/-1 Cup sec.
- High Durability
Special Modification for Diaphragm Pump, Solenoid Valve, etc to ensure
high precise performance.
- Smart Lubrication system - Japan Patent.
Self-Suck auto lubrication system to ensure longer life of machine.
Almost all lubrication pump of viscosity controller are not "Self-Suck" style.
Not "Self-Suck " type lubrication pump can not suck refilled oil after empty.
That is reason why steady lubrication could not be done to diaphragm pump.
VISCON developed Smart lubrication pump is "Self-Suck" type pump.
By this VISCON Smart lubrication pump, users can use viscosity controller
more longer time in steady conditions.
- Stainless steel (SUS304) 16ltr solvent tank
Almost all other viscosity controller has Plastic solvent tank.
Plastic solvent tank is easy to be broken, also keep statics.
To solve users’ long time headache, VISCON adopt stainless steel
solvent tank. Capacity is 16 ltr, this big volume of solvent tank
make operator’s work less. Good news for operator.
- Auto Turbo Wash system,Japan Patent.
Adopt latest technology for the complete effective cleaning.
By Auto "TURBO WASH", users can reduce washing time less half. can reduce labor less half,
and can increase washing effect 2 times.
- Anti- Dirty SUS machine body
Strong machine body and easy cleaning.
- Prevention from Ink dirty
Special protector in machine body to keep away from ink dirty.
- Explosion-Proof design
For the safety production.
- Quick investment refund
Within 8 months will get investment refund. Then this machine becomes
- Reliable and quick after sales service
With professional agent service to ensure the production smoothly running.
Our overseas agent can advice, educate, and repair in each local country.
Not only selling, but helping is our VISCON Group concept.
