Presentations in this session include welding (i.e., friction stir, ultrasonic, resistance, arc, laser, etc.) and joining (i.e., brazing, soldering, riveting, bolting, and adhesives) of similar or dissimilar materials (i.e., plastics, composites, aluminum, magnesium, titanium, and conventional and advanced high strength steels). Strength, fracture, and fatigue implications of these methodologies will be discussed.

The reduction of emissions in gasoline and diesel engines is driving the introduction of systems implementing additives in liquid form: in particular water for injection systems in gasoline engines and urea solutions (AD-blue) in SCR systems in diesel engines. Unfortunately water and AD-Blue can freeze in the car operative temperature range. In both cases the tanks must be equipped with heaters to guarantee a sufficient amount of additives in liquid form. Currently used technologies are ceramic PTC elements and distributed metal resistors. Ceramic PTC based heaters concentrate all the power in small volumes. They need thermally conductive elements distributing the power over a wide area. The assembly is complex and the cost of the metal parts and related packaging technologies used to insulate the heater from the environment (water or urea) is typically high. Metal resistors are cheaper but must be controlled in current.

In the last decade a new Zinc-Magnesium-Aluminium coating (ZM-coating) for HDG steel sheet was developed at voestalpine. Unlike the well-established ZnAlMg-coatings from Japan which have significant higher alloying contents (for building applications), this ZincMagnesium coating (ZM) is also specifically designed to meet the requirements of car manufacturers. voestalpine's ZM-coating (corrender) is already approved by many OEMs and is currently used in the car body as a substitute for GI. Typical applications are structural as well as exposed parts. The ZM-coating introduced by voestalpine is in the upper range of ZM-alloying compositions, which was set by SAE and VDA (German Association of the Automotive Industry) to be within 1.0 to 2.0 wt% Mg and 1.0 to 3.0 wt% Al. The properties of these “European” Zinc-Magnesium coatings are well comparable within this range.

The automotive industry, known for its competitiveness & innovations globally, researches for continuous improvement of part performances along with reduction of cost & weight. These are amongst the top priority goals across all OEMs. In the long list of automobile parts, pipe clamps have paved their way of design through generations from being of metal to plastic that has expanded its scope of application & performance. In an automobile, plastic clamps are widely used to hold single or multiple water, fuel or brake pipes of various diameters to vehicle body at various locations such as underbody (prone to stone chipping) or engine room (prone to high temperatures), etc. Plastic clamps are preferred over metallic clamps for their cost, weight, performance & productivity. Primarily, in all application areas, a clamp must be able to hold the pipes with consistent & sufficient performance that is quantified through parameters such as thrust force and pipe removal force.

Plastic hollow articles are used in automotive applications such as high pressure fluid bottles, active globe box knee airbags, etc. Welding of plastic hollow articles to create a pressure vessel is a challenge. The weakest points are usually the weld seam where the part tends to separate under internal pressure. The reason for the weakness is that the weld is configured as an L-shaped joint and the loading is in peel. The L-shaped weld joint is the result of the injection molding limitations such as die lock and also the welding process adopted with its perceived design limitations. A new weld design to form plastic hollow articles is conceived. Its design is T-shaped such that the joint loading under pressure is no longer in peel but in tension, vertically to the weld surface. This weld design can be easily achieved, overcoming the limitation of die lock in injection molding and by the hot plate weld design adopted for this welding.

Abstract Simulation tools are becoming more and more popular in the automotive industry since they can significantly reduce the costs required for development of new models. Currently there are many computational fluid dynamics (CFD) tools available on the market and becoming indispensable tools for R&D in many of the automotive applications. However there are some applications which require much effort by highly skilled engineers to prepare the model and impractical level of computation time even using a cluster computer using the conventional CFD tools due to the nature of physics and complexity of a geometry such like dip painting process. Therefore, corrosion protection engineers are striving to find an alternative solution. Another issue is that the main focus of those available CFD tools are problems occurring during the dip paint simulations and they omit problems occurring after the object dips out from the bath, such as retained water or bake drips.

Abstract Cost reduction is an important issue in the intense competition automotive industry. Interior parts which are mainly consist of plastic have same issue. The manufacturing main processes of plastic products are injection and assemble and the cost of injection depends on injection cycle time. Therefore many studies for the reduction of injection cycle time have been implemented. However the researches based on engineer's experiences have limits so, nowadays many studies utilize CAE. In this paper, the study for the reduction of cycle time focused on injection molding design. To satisfy appearance quality with the reduction of cycle time, the design of injection molding was optimized by using CAE. The result of CAE showed many causes and effects of problems. The optimization of injection molding design improved the quality with the reduction of cycle time. Finally, the product based on CAE showed good quality and cycle time reduction in comparison with previous products.
