The SAE 2004 World Congress provides industry suppliers the opportunity to showcase their products, services, and technologies to the global automotive community. Show Daily editors review what some exhibiting companies are displaying this year. Marking system EFD, Inc.’s MicroMark precision-spray marking system produces consistent spots and stripes from 5 to 30 mm (0.2 to 1.2 in) wide. It reduces downtime on automated and semi-automated production lines. Typical applications include color-coding to differentiate between similar components, pass-fail status indication, and designation as to whether a process has been performed. A precision-spray valve and low-volume lowpressure air are used to make the uniform spots and stripes without mist. A high-transfer efficiency and quick cutoff improve part appearance and cleanliness, while a short microburst of air after each shot keeps the nozzle from clogging and reduces maintenance. A microprocessor-based controller simplifies system setup and operation and can be interfaced with a programmable logic controller. Booth 1245 Scanning technique X-ray Computed Tomography (X-ray CT) from Hitachi is an X-ray scanning technique that performs dimensional verifications, density analysis, and integrity analysis of assemblies. The technique is suitable for reverse engineering components and for the non-destructive testing of components to improve quality and accelerate the engineering process, thus reducing component development time and decreasing costs. The technology includes StereoCooker software for CT dimensional analysis and FeatureMaker to convert CT data to CAD data. Typical automotive applications for the program include cylinder blocks, heads, transmissions, and other powertrain components. X-ray CT technology is applicable for materials such as aluminum, steel, plastics, and composites; trial scans are available. Booth 351 Test calibration MTS Systems Corp. offers the computer-aided engineering (CAE) Calibrator software product for their NASTRAN users that leverages test and other external data to interactively compare, correlate, calibrate, and automatically update CAE models for structural dynamics. The software ensures that a CAE model’s performance matches test data, other CAE models, and user-entered design targets. Beta testing of CAE Calibrator confirms it updates models instantaneously, eliminating the manual effort that is often required to implement design changes in real models. Automated and interactive studies or iterations on potential changes are also accomplished more quickly. The software will synchronize orientation, scaling, and results and will update designs in the NASTRAN input deck automatically. Booth 621 Keypad technology GM Nameplate offers an electroluminescent (EL) keypad technology that integrates EL lighting with elastomers to create highly functional, lightweight, switch units that use fewer components than conventional keypads with light pipes or light dams and mechanical switches. The keypads operate at temperature ranges from -30 to +80°C (- 22 to +176°F) with a voltage range of 20- 200 V ac and a frequency of 50-3000 Hz. Advantages include no light pipes to design or mold, a 0.012-in (0.3-mm) flexible light source, reduced power consumption, sealed top-surface, laser-etched graphics, variable tactile response from the dual-layer elastomer construction, and different day and night graphic colors. Booth 1152 Test rig A test rig from Aries Ingenieria Y Sistemas, S.A. complies with existing test protocols as well as the new head-restraint testing protocol proposed by the National Highway Traffic Safety Administration. The system is based on electrical actuators and includes a complete control system to program force-loading profiles. Its features include a high-precision laser adjustment system, a compact heavy-duty mechanical design, and many possibilities of test configuration, including open code for the user. Booth 432 Casting impregnation The continuous flow impregnation system from Godfrey & Wing fulfills the need for direct-coupled casting impregnation within automotive manufacturing facilities. It is based on a dry vacuum- and pressure-process where vacuum cycles work on the part, not the air surrounding the part, and resin is maintained in its purest form, not entrained with air or water. The part experiences a significant positive pressure, and recovery and conservation of resin is used in lieu of recycling. Resin is prevented from entering the plant’s waste stream through efficient recovery, negating the need for additional equipment and chemicals to process specialty resins. Through automated, repeatable handling, the system processes the most complicated, highly machined parts without the risk of damage or contamination. Booth 2652 12 Wednesday, March 10, 2004
Polyethylene resins Raprex resins from Ion Beam Applications (IBA) and its subsidiary IBA Advanced Applications provide improved physical properties without the use of chemical cross-linking agents. Use of the resins precludes the need for chemical additives. The crosslinking is achieved before forming the finished parts through radiation processing of the base polyethylene resin. The resins are available in three grades: extrusion grade raprex 200 for pipe, tubing, containers, and profiles; injection molding grade raprex 200 for tote bins, pump housings, industrial clamps, and luggage handles; and film grade raprex 300 for steel pipe sleeves, and timber pole sleeves. Booth 1712 Refrigeration systems Cryogenic industrial freezers from Russells Technical Products Inc. are capable of maintaining temperatures as low as -120°F (-85°C). The company's expanded product line includes heavy-duty industrial freezers for the heat-treat industry. Standard sizes range from 15 ft 3 to 60 ft 3 (0.42 m 3 to 1.7 m 3 ) in chest-type and frontopening configurations. Load capacities range from 100 lb to 2000 lb (45 kg to 900 kg) and up. Options include microprocessor programming, cycle timers, Nema 12 electrical, and disconnects. Booth 744 Metering pumps Metering pumps from Thomas Magnete allow for high meteringprecision with an exactly defined swept volume and minimum noise. The solenoid armature in the pumps is simultaneously the pump plunger. With no electrical current, all cavities are filled with fuel. When current is fed to the coil, the armature displaces the piston against a spring. The pump plunger raises a valve ball and expels the medium from the pump while closing the supply apertures. When the current is switched off, the spring presses the armature and piston back. This induces a sub-atmospheric pressure in the pump space, and the fuel enters through the reopened supply apertures. Booth 2041 Snap rings Smalley Steel Ring Co.’s snap rings are made by coiling flat wire, producing a snap ring that has no protruding ears or burrs to interfere with performance. The rings are stocked in carbon steel with diameters ranging from 0.5 in to 11 in (13 mm to 279 mm). Special designs are available and can be economically produced in stainless steel because coiling produces no scrap. The rings can withstand high loads and impact loading. Booth 1653 Isolation systems AirLock enclosure systems from Simplex Isolation Systems are modular cleanrooms used for paint lines, transmission and engine assembly areas, and manufacturing and assembly of electronic controls and dash components. They provide contamination control, and are available for use as modular dividers. Both soft-wall and hard-wall models are offered, and each can be latched together depending on intended use.
