42 Technology and INFICON develop novel manufacturing approach for pressure sensor

42 Technology and INFICON AG, a leading industrial sensor company, have worked together to devise novel automated process steps for the manufacture of sensor wire filaments.

The new approach can automate all of the critical, highly labour-intensive steps involved in the production and assembly of special coiled filaments for use in specific types of precise vacuum sensors and promises to improve process reliability, increase manufacturing efficiency and boost production output.

The system is designed to replace INFICON’s existing manual manufacturing process that requires skilled steps which can be the source of reliability, yield and repeatability issues, while providing a greater throughput and reduced exposure to hazardous chemicals.  This improved process will enable INFICON to produce completed filaments for a range of present and future sensor products with reduced stock levels to ensure it can always meet changing customer demands.

Automating the existing process was particularly difficult because it involved so many different disciplines, handling and pre-treatment of short lengths of coiled filaments in liquids, as well as component assembly and test.  However, following an in-depth analysis of the process, 42 Technology’s manufacturing specialists worked alongside INFICON’s process engineers to propose several innovative solutions before designing a number of working rigs that demonstrated proof of concept.

“42 Technology has worked very efficiently alongside our in-house team to automate one of our most challenging and intricate manufacturing processes.  Their innovative, pragmatic solution will deliver multiple business benefits but more importantly we can now automate a labour-intensive, repetitive and unpleasant manufacturing process and re-assign our highly-trained technicians to more varied and interesting work,” said Christian Berg, technology director at INFICON.
