Sophisticated plating line forprint head manufacturer


Specialist plating


equipment designers and manufacturers, Plasticraft, have installed ahighly sophisticated


electroless plating line that is meeting


the specific needs of leading industrial print head manufacturer, Xaar plc.


The facility,installed at Xaar’s Huntingdon manufacturing facility,fulfils anumber of key processing requirements –not least the need to operate within the company’s clean room manufacturing environment.


The Plasticraft system comprises afully enclosed process line that is dedicated to the electroless plating of Xaar’s acclaimed X1001 printer head, which is installed on printers designed for arange of applications –from barcode labels to ceramic printing.Featuring 1000 individual nozzles, the plating,onto aceramic substrate, has to achieve stringent parameters in terms of consistency and thickness –acoating of just a few microns, for example, is required.


RobMcCarthy,Programme Manager at Xaar, explains the role played by the Plasticraft equipment: “Substrates are loaded in batches of 36 on to one of four jigs, which are then collected by arobotic gantry that transports the products through the plating process,” he says. “The new line has been installed alongside an existing manual facility and will enhance our commitment to production consistency and quality while, at the same time, increasing throughput and removing the human/chemical interface.”


The operation is centred on two parallel rows of tanks – one of which is dedicated to surface preparation, and the other to the application of plating process solutions and rinsing –with both mechanical and air agitation applied at key positions. The Plasticraft design includes a3-Axis transportation and fixturing system, whilst the company also liaised closely with Xaar to accommodate both the company’s air filtration requirements and the delivery of chemical solutions, pumped from reservoirs external to the clean room.


The system is fully automatic, including chemical dosing and data logging operations, and conducts acontinuous analysis of the chemical solution to ensure that its make-up remains consistent throughout the process. The combination of solution, processing time and temperature, says Plasticraft, is central to the quality results that are achieved.


“Although compact in design, the line fulfils complex handling and electroless plating operations, and is an excellent demonstration of our understanding of plating equipment and processes, and their application in aclean room environment,” said Plasticraft’s Managing Director,Mike Priddle.


“Xaar are regarded worldwide as one of the main manufacturers and suppliers in the specialist industry it supplies, so we are delighted to be able to work closely with the company to enhance its high quality manufacturing process.”
