Stencil Production


Tannlin operate Stencil production sites at Prestwick (Scotland), Hook (England) and have further European operations in Budapest in Hungary and Timisoara in Romania. Each facility is a copy exact production operation with dedicated local CAD and technology support staff. The sites are fully equipped with the latest Tannlin T11 stencil laser cutting systems and ancillary equipment. They operate under the strict Tannlin operating processes and quality management system ensuring we meet our requirements for accuracy and repeatability. Customer communication and operational control is all managed through our proprietary on-line Blueprint application.
