SM814-2 ALPHA TETRA Stencil Frame System DESCRIPTION ALPHA TETRA is a revolutionary patented precision stencil mounting system that eliminates the need for a dedicated frame for each stencil, unlike traditional epoxy to mesh stencils. One frame is all you need for each printer. It is very rigid and gives consistent, high accuracy printing over a long working life cycle. The ALPHA TETRA System includes a full range of accessories to provide a total solution for your stencil management requirements. The ALPHA TETRA Frame offers compatibility with both standard TETRA foils and optional TETRA-VG stencil foils to ensure an ALPHA Stencil Solution for every application! FEATURES AND BENEFITS Flexible: The ALPHA TETRA system is designed for use on most popular printers in use today. ALPHA TETRA foils can be used with all kinds of squeegee blades and paste application systems. The ALPHA TETRA Frame is both compatible with ALPHA TETRA and ALPHA TETRA-VG foils. Quick: The stencil foils can be changed in less than one minute - many times faster than most other universal framing systems. Accurate foil location is predetermined by locator pins. Accurate foil location is predetermined by locator pins or the extruded edges of the TETRA-VG foils. Accurate: Achieving stencil stability, print accuracy and sharp registration is never a problem with the ALPHA TETRA system. The stencil foils are secured directly to the frame which applies mechanical 4-way multipoint uniform tensioning with no foil distortion, which is nearly 40% stronger than mesh mounted stencils. These connections and tensioning features provide significant performance advantages: Five times less deflection (Image Float) during printing. Over 2 times greater positional accuracy. No mesh stretch effects even after tens of thousands of print cycles. No adverse effects from cleaning solvents. Space Saving: The ALPHA TETRA work station can save up to 70% in valuable floor space by providing a convenient, mobile stencil foil storage unit, that takes over 150 stencils in individual cardboard storage wallets. The mobile work station can be positioned close to the printer to save precious stencil retrieval time. Cost Saving: Lower costs through improved yields, reduced storage, reduced downtime, no return or recycling of used frames.
