With digital flatbed printers making more inroads into the signage and graphics industries, the need for effective substrate holddown remains high. Be they digital or screen print, experienced sign makers all recognize the advantages of a vacuum holddown table, especially when it comes to accuracy or temporary holddown.
One company that specializes in the production of precision vacuum holddown tables for any flatbed application is Graphic Parts International Inc. (GPI), a Chicago based manufacturer and global supplier of OEM vacuum tables.
To achieve the perfectly flat surface required for high-quality printing, vacuum tables are manufactured using a proprietary Stay-Flat process. Built around an all-aluminum honeycomb core for maximum airflow and covered with the thickest top and bottom plates for extra strength, the non-oxidizing, anodized aluminum tabletop resists warping and is extremely durable. For tougher applications GPI offers a stainless-steel surface, as well as Formica and phenolic tabletops for material sensitive and non-conductive applications. Oversized substrates are no problem for GPI either, who produces the world's largest vacuum table at 10x25 feet with a 250 sqft surface of highly controlled holddown. Maintenance-free vacuum motors feature a multi-stage centrifugal design to quickly and quietly provide the proper amount of holddown, and in addition to reducing noise, the brushless motors help to improve workplace safety because they emit no sparks. Available in a range of operating voltages with airflow valves to complete any vacuum setup, each table is custom built to client specification at the company's main production facility and world headquarters in Chicago.
If you want to restore the performance of your existing vacuum table without the expense of purchasing a new one, GPI also offers resurfacing services to provide like new finish and flatness to your tabletop. OEM companies and dealer inquiries invited.
