Principle and Functional Characteristics of Precision Coating Machine
2019-03-13
Manual scraper coating can be said to be the first method of coating used by human beings, and then there was silk screen coating. It is worth mentioning that the silk screen scraper coating machine was born in China, the Western Han Dynasty has a history of this kind of coated fabric and leather. The modern roll coating machine is based on the invention of Gutengsberg Rotary Printing Machine after gradual improvement.
Precision coating is developing slowly with the rapid development of modern electronic industry. Precision coating technology was proposed by Roy Downhawn, founder of ASI in 1970.
Precision coating technology has matured through the development of the United States, Japan and European countries, and Taiwan still lacks in technology. The obstacle of restricting the import of air-floated ovens in our country lies in the high price. The representative manufacturers of imported air-floated ovens are ASI, MEGTEC, DAWIS STANDARD, Hirano, Inoue, Toray and BMB of Switzerland.
Precision coating machine is defined as the required coating accuracy error is only (+1u). Precision coating machine is relatively mature in Germany, the United States and Japan. The main features of the precise coating machine are: slit extrusion, precise wiring rod smoothing, air-floating drying, magnetic damping of the coating head against vibration of the fuselage, gas-liquid buffer bracket.
Several functions of modern precision coating machine:
SLOT DIE extrusion coating head has been developed to multi-layer jet sheet wall effect controlled by distributor, multi-layer coatings with different functions are co-extruded at one time.
Laminar flow, air-floated dust-free drying. Attached solvent recovery system.
Vacuum suction roller traction.
For plastic film, soft X-ray coating thickness detection, closed-loop control servo motor precision feeding system.
CCD digital camera defect detection system.
The difference between precision coater and common coater is that:
Extrusion die coating head
Isolate body vibration
Laminar Floating Drying
On-line coating thickness control
The error is (+1u)
Ultra-thin coating up to 0.5-1 u can be carried out.
Wire-rod smoothing is accurate and easy to clean
Accurate Flange Tension Control
