Product Description

DRF squeegee is made of German high-precision steel belt and advanced technology. It is used for coating and printing of various gravure printing presses, flexo printing, laminating, transfer printing, anodized aluminum, printing, wood grain, wallpaper, etc.
　 Features:
　　1. Stable ink color tone----make sure to wipe off the ink.
　　2. Extend the service life of the plate roller-----Use high-purity steel to reduce the pressure of the scraper.
　　3. The life of the tool tip becomes longer and economical.
　Parameter:
　　 Length: 100 meters/roll or customized
　　 thickness: 0.15-0.20mm
　　 Width: 30-60mm
　　 Linearity: The linearity deviation is less than 0.6mm per 3000mm length
　 Hardness: 585HV±15HV
　　Applicable machine speed: ≤80M/min
common problem:

problem	reason	Solution
Vague	The contact area is too large	Increase the blade angle and use a thinner blade Reduce scraper pressure, use shorter scraper and back knife Use a thinner scraper (less deviation)
	The barrel polishing is too rough	Reduce the roughness of the drum
	Ink drying speed is too slow	Add quick-drying solvent and check the viscosity, increase the distance between the scraper and the knife holder The ink temperature is too low or does not match the humidity of the printing room Check whether the pH of the ink is appropriate (water-based ink)
	Scraper wears in abrasive ink	Use long-life scraper
Tailing	There is ink drying on the upper or lower scraper	Clean the squeegee and keep the ink pump running when the printing press is stopped Reduce ink viscosity
Tailing	Damaged squeegee blade	Reduce the pressure of the squeegee and use a long-life squeegee Increase the angle, reduce the roughness of the drum (chrome plating)
