Vacuum tables for flat composite holddown

© Graphic Parts International

G.P.I. (Graphic Parts International), a foremost supplier of precision vacuum holddown tables to the fabrication industry, is recognized for its ability to produce the flat and good performing vacuum tables. The company excels at building customized airflow systems, and the proprietary fabrication process used to produce the Stay-Flat™ Vacuum Table results in a non-warping, non-oxidizing flatbed. 

Whether you are making solar panels or producing aircraft fuselages, substrates need to be handled with care and held in exact position while undergoing drilling, laminating or other processes. Vacuum tables are useful for rapid prototyping, CNC routing, and a host of manufacturing applications wherever substrate holddown is required. Available with cutouts, inserts, disappearing registration guides, lift pins and more, the company’s vacuum tables are easily customized to suit almost any need. A variety of sizes (up to 10 X 25’), configurations, and surfaces including anodized aluminum and stainless steel are among the many options offered. For non-conductive and sensitive material applications, phenolic tabletops are also available. Tables are built around an all-aluminum honeycomb core, and the sandwich design yields a superior strength-to-weight ratio and the flattest table in the industry. For added durability, all vacuum tables come standard with extra-thick top and bottom plates. Brushless, maintenance-free vacuum motors are ultra-quiet and emit no sparks, providing a safe and low-noise means of powering the system. For precision removal of component or substrate, blowback devices provide the exact flotation required for successful material handling. Using only the highest grade aluminum, all tables are made to order and built to customer specification at the company’s main production facility in Chicago, IL.
