Expertise on show

HERAEUS NOBLELIGHT, a specialist in the production and application of high quality energy sources covering the electro-magnetic spectrum from ultraviolet to infrared, offers products and systems to provide efficient solutions to drying, heating and curing problems and has announced it will be showing examples of its expertise at Advanced Engineering, 2nd-3rd November, NEC Birmingham, Stand L100.
The company says it recently supplied a fast response medium wave (FRMW) infrared heating system to Dura Automotive Systems of Castle Bromwich to ensure the reliable and precise adhesion of molded thermoplastic sealings to custom-designed, automotive glass windows. The system is located in a robotic cell and integrates exactly with the robot cycle.
The factory at Castle Bromwich specialises in automotive structures, glass and trim solutions. When it was awarded an important contract by a major British car maker to produce quarter lights featuring a molded sealing around the edges, Dura contacted Bauromat (UK) a recognised leader in robot manufacturing cells. Consequently, a cell featuring two Kuka robots was installed to carry out the delicate operation of applying a prime adhesive coating to the quarter glass to allow a molded seal to be affixed in a subsequent operation. However to ensure efficient adhesion of the molded seal to the prime coating it was necessary to heat the coating to a specified temperature to achieve the required cure and 'tackiness' before the glass is precisely over-molded in a further operation.
Infra-red was considered to provide the best solution to this problem and tests were carried out at Heraeus Noblelightís Applications Centre in Neston, Wirral, and these proved so successful that a 24 kW Carbon medium infra red (CIR) system was installed in the robot manufacturing cell. This is designed to heat one large item of glass or two smaller ones, according to production requirements and is Pyrometer controlled to maintain a set coating surface temperature.
