Product Description

KRUPP squeegee is specially made of German high-quality steel and Swiss high-precision technology to meet the various needs of customers. It is constantly updated to effectively prevent problems such as color tone, wire drawing, bleeding, streaks, and chrome layer wear. It is suitable for Medium and high-speed printing machines at home and abroad.
Applicable fields: gravure packaging printing, gravure publishing printing, flexographic printing, flexographic UV offset printing glazing, decorative material printing, composite, bronzing, anodized aluminum, printing, thermal transfer, thick paper, wallpaper, decals, wood grain, Leather coating and printing.
　　 Features:
1. Extremely long service life and abrasion resistance 3-5 times higher than that of ordinary squeegee. Because KRUPP squeegee uses high-precision technology to provide a constant contact area, it can be operated with minimum pressure, which effectively guarantees the service life of the squeegee and reduces the wear of the roller. , More good scraping effect.
　　2. Excellent elasticity. The good elasticity of the KRUPP squeegee can adapt to the violent beating caused by the uneven electric engraving plate under high-speed operation, and will not affect the squeegee effect of the next pattern.
　　Parameter:
　　 Length: 100 meters/roll or customized
　　 Thickness: 0.15-0.50mm or customized
　　Width: 10-60mm
　　 Linearity: The linearity deviation is less than 0.6mm per 3000mm length
　　 Hardness: 585HV±15HV
　　Applicable machine speed: ≤230M/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)
