Details
Different from traditional solvent-based paint lines, this line adopts a full-process low-volatile, humidity & temperature adaptive system, matching dedicated atomization, drying and air circulation units for water-borne coatings. It fully solves the technical difficulties of water-based paint such as slow drying, high surface tension, easy dust adhesion and sagging. Combined with reciprocating spraying robots or 6-axis explosion-proof spray robots, it realizes stable mass production. Featuring eco-friendliness, low VOC emission, safe operation and excellent coating appearance, it complies with global environmental regulations and automotive industry coating standards, becoming the mainstream upgrading solution for modern automotive painting workshops.

FAQ
Q1: What is the biggest difference between this line and traditional solvent-based paint line?
A1: This line is equipped with precise constant temperature & humidity system and three-stage gradient drying structure, specially developed for the characteristics of water-based paint. It has much lower VOC emission and higher operation safety.
Q2: Will water-based paint produce whitening or blistering on auto parts?
A2: No. The whole line keeps stable humidity and adopts step-by-step moisture removal process, which effectively avoids whitening, blistering and watermarks.
Q3: Can it match robots and reciprocating spraying machines?
A3: Yes. It is perfectly compatible with 6-axis spray robots and 2/3-axis reciprocating machines for different part production demands.
Q4: Is the drying speed of water-based paint slow and affects production efficiency?
A4: The optimized graded drying process shortens the overall cycle time. The line speed can be adjusted freely to meet high-volume mass production requirements.
Q5: Does the equipment meet international environmental protection standards?
A5: Definitely. The supporting waste gas and water treatment system makes all emission indicators meet local and international environmental regulations for automotive industry.
