Chromium plating lines

Technological process at chromium line

There is need surface pretreatment for parts before chromium plating process, that applies on any chromium plating technology. This surface pretreatment is right to do by dipping. Parts for galvanic plating are degreased by dip or spray in chemical bath during the surface pretreatment. Effect of dip degreasing could be enhanced by ultrasonic or electrolytic way.  Parts need to rinsed after degreasing and then according to needs etched/pickled with following rinses. Pretreatment is finished and chromium plating comes. Chromium plating is based on surface coating needs. Chromium plating usually is done in bath with hexavalent chromium known as hard chrome or in trivalent chromium bath known as decorative chrome. Chromium plated goods is rinsed and dried afterwards. Goods is transported by manipulators between tanks. Whole design of chromium plating line is in accordance with customer needs. There is given special attention to reach high quality of treated surface, high efficiency and reasonable price of technological device. 

Goods transport at chromium plating line

Parts that should be plated are mostly hanged on racks or tossed into the barrels. Line could be designed in one straight branch or in straight branch where hanging equipment is returned (racks or barrels) or two branches line. More branches for one line usually means line where are more technologies. Line as is it was written use barrel or rack conception, however its combination is usual as well. Manipulation system of line contains lifting stands, galvanic manipulators and transport trucks. Galvanic manipulator we offer in these types - underhanging, portal, half-portal, side. Manipulators could be covered with inner ventilated area. Manipulators could be made with possibility of tilting goods.

Wastes from chromium plating line

Process baths emits waste air (gas, vapors). This waste air could alkaline or acidic according to type bath. This waste air is sucked off by line ventilation system. Ventilation system is usually upgraded for scrubber with integrated droplet separator, which cleanse waste air and remove droplets. Waste water from baths is another important waste created by chromium plating line. This water could be cleansed on our automatic waste water treatment plants or on our manual waste water treatment plants.
