ITW/BGK Engineered System

Designed to apply and cure a variety of liquid coatings, primarily on plastic parts, although metal parts can be processed as well with equal effectiveness.  The basic technology employed on both lines is a Chain on Edge transportation conveyor, allowing processing speeds up to 30 feet per minute, flexible part positioning with part centerlines on 2” multiples, automated de-ionizing air cleaning, in-line automated Plasma Treatment, automatic “Feather Duster” parts cleaning and vacuum, and multiples spray booths and application devices.

While originally designed to process mobile phone housings, the line can accommodate the processing of parts as large as accessory covers for laptop computers for Dell, as well as parts as geometrically complex as cable box bezels for Scientific Atlanta.  The line exploits the numerous advantages of high transfer efficiency provided by electrostatic Rotary Atomizers for application and UV Curing Technology for excellent Physical Properties and extremely fast processing speeds. 

The California Air Resources Board has identified the Electrostatic application method in combination with High Solids UV Coatings as an Environmental “Best Practice”, and there is no method of processing small plastic parts that is lower cost.  The specific difference between the two lines is described here in each line’s process Sequence.

This line was the original source for UV top coating of the first Cubic Printed Nokia mobile phone housings processed beginning in May of 96.  It was later adapted to process Solid Color mobile phone housings when Nokia shifted its design strategy away from Cubic Printing.  The line has been used to process mobile phone housings for Ericsson, Sony, Motorola, and Qualcomm/Kyocera, and Research In Motion.  It has also been used to process UV Hard Coating for Digital User Interface Bezels for Kohler Bath.

This line was engineered and installed in 2000, it has the ability to use 1K, 2K, or UV chemistries, as well as more than one color coat in sequence.  It includes a 3rd application booth, which can be used to apply either a second layer of a Base Coat, or a 2K top coat, depending on the processing pedigree needed by the customer.  The final booth of the 3 in sequence is primarily used to apply UV cured materials.

We have many more pics, a DVD Video, Drawings and many other forms of documentation on this line.  Give us a call if you would like more information or would like to schedule a personal tour of this equipment.
