Chromate lines
Devices for dipping surface treatment on zinced parts or zinc parts or zinc alloy parts, where come chromate process we call chromate lines. Chromate lines are supplied as functional unit, however we can supply even parts (tanks, manipulation systems, hanging devices, ovens, plants for waste water cleansing, air technique (ventilation), water management...) Our chromate lines are made according to customer need. Every chromate line have unique measures.
Technological process chromate line
Chromate technology is used for zinc parts or parts from zinc alloys. Chromate process requires pretreament process. This pretreatment should be dipping way. Parts need to be degreased, rinsed and in case of need etched/pickled with following rinses. Chromate might yellow, blue, black or olive. Chromated parts need to be rinsed, sealed and dried. Goods is transported by manipulators between tanks. Whole design of chromate 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. Technological process of chromate technology for non zinc parts or alloys is described in section zinc lines.
Goods transport at chromate line
Parts that should be chromate 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 in two branches. More branches for one line usually means line where are more technologies. Manipulation system of line contains lifting stands, manipulators and transport trucks. 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 chromate 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 chromate line. This water could be cleansed on our automatic waste water treatment plants or on our manual waste water treatment plants.
