This technology has been proven for years, however, the process is quite time consuming and expensive. Applications with porous sintered materials are limited due to high cost and complex machining requirements.   METAPOR® offers new possibilities as a result of its easy machining properties. METAPOR® vacuum clamping devices permits holding of extremely sensitive parts without deformation, since there are no drill holes or channels. Static jam while ejecting can be eliminated using compressed air, which creates a smooth and even air cushion. METAPOR® CE 100 White chuck with integrated temperature sensor for use in measuring device     Different METAPOR® Products are available for Vacuum Clamping Devices METAPOR® BF100 AL is advantageous for vacuum clamping devices for fixation of sensitive materials like very thin films (0,01 mm) or for engraving flat objects. METAPOR® CE 100 White is an extremely fine porous material with a white non-reflexive surface and is easily workable. It has proven to be very useful in silicon-wafer production, also due to its strong surface hardness and precision milling capability. Flatness of vauum chuck surfaces less than 5 micron. Clean room surrounding (class 10) approved. Vacuum clamping devices made from METAPOR® MC 100 AL are used for complex 3D-shapes and for complete surface coverage, to clamp parts and films without any deformation.   METAPOR® CE 100 White Semiconductor chuck   Advantages Even vacuum on the entire surface Deformation-free fixing due to micro-porous surface Economical construction; no drill-holes needed whatsoever   METAPOR® CE 100 White chuck for wafer-plates   Applications Plane clamping worktables, printing tables, measuring tables, clamping inserts within compression moulds Profile clamping vacuum supported form grippers for complex tools, trimming of thermoformed parts   METAPOR® BF 100 AL clamping device for cheque cards made by WITTE   Technical Data Product Application Characteristics Density (g/cm3) Flexural strength (N/mm2) Air flow rates at pressure difference of 1 bar / 10 mm METAPOR slab (per cm2 per minute in litres) BF 100 AL • Plane clamping • Very sensitive parts and thin films • Partial coverage of clamping surface possible 1.8 56 1.4 CE 100 WHITE • Plane clamping • High surface resistant • Very sensitive parts and thin films – semiconductor industry • Partial coverage of clamping surface possible 1.7 28,5 1.4 MC 100 AL • Plane and profile clamping • Full coverage of clamping surface required • Maximum airflow 1.7 25 11.5   Sketch of a METAPOR® Vacuum Clamping Device Based plate with air distribution channels METAPOR® - part inserted Gap filled with ARALDIT 2014 - adhesive, top surface milled   METAPOR® is a registered trademark of Portec in Switzerland.   © - All Rights Reserved by Portec Ltd.
