Gütersloh, DE
Westaflex is a large global HVAC (Heating, Ventilating, and Air Conditioning) brand owned by Westaflex Holding and based in Gütersloh, Germany. Founded in in 1933 by Lorenz and Ferdinand Westerbarkey, who developed a coil-based tube forming machine, the first stable and any-shape tube of its kind. Westaflex products are used in a variety of applications including automotive production, train technology (ICE ventilation), for the air supply and ventilation of living spaces, exhaust technology and water treatment. Westaflex places a great deal of emphasis on the quality of its products and the role of employee participation, engagement and communication in achieving this quality. Westaflex's corporate motto is "connections which pay"; something which applies not only to their products but also to the value they place on the connections they have with their customers and with each other. This change in culture is a gradual process rather than a one-off initiative. It takes a lot of time and will probably never be finished. We believe that everyone needs to have a sense for the work of the company as a whole. For example, the people working the machines in the factory need this to understand what the ramifications of a mistake in the production process are. We wanted to make sure, in line with our open culture, that this was not a management project imposed from above and that everyone was engaged in making it better.

Hydroforming is a metal fabricating and forming process which allows the shaping of metals such as steel, stainless steel, copper, aluminum, and brass. This process is a cost-effective and specialized type of die molding that utilizes highly pressurized fluid to form metal. Tube hydroforming is the expansion of metal tubes into a shape using two die halves, which contain the raw tube. Hydroforming is used to replace the older process of stamping two part halves and welding them together. It is also used to make parts both more efficiently by eliminating welding as well as creating complex shapes and contours.

Tube forming machine using three point bending
A tube forming machine for making a tube from a sheet is disclosed. The forming rolls of this invention include various V-shaped rolls at least some of which are used as part of a three-point bending technique. The three-point bending technique entails the use of a V-shaped bottom roll and a narrow top roll. The sheet is shaped running the sheet through a gap between the narrow top roll and the V-shaped bottom roll. The technique allows a wide variety of tubing to be made from the same set of forming rolls, because the curvature obtained in a sheet can be varied by opening or closing the gap. A V-shaped forming roll disclosed herein is also used at a pinch roll stand with a second complementary V-shaped roll. The pinch roll stand of this invention creates an initial V-shaped sheet which facilitates the threading of the sheet at the start of a forming operation. Brimmed rolls are also disclosed. Brimmed rolls have a relatively sharp included angle, and are used to engage the edges of a sheet and to press the sheet against a single bottom roll in brimmed roll stand.

Analysis of wall glucans from yeast, hyphal and germ-tube forming cells of Candida albicans.
Acid-soluble and alkali-insoluble glucan fractions were prepared from yeast, hyphal and germ-tube forming cells of Candida albicans. Alkali-insoluble glucan was also extracted from purified yeast cell walls. Paper chromatography of partial acid hydrolysates confirmed that the glucan preparations contained beta(1----3)- and beta(1----6)-chains but no mixed intra-chain beta(1----3)/(1----6) linkages. Methylation and 13C-NMR analyses showed that the acid-soluble glucan consisted of a highly branched polymer composed mainly (67.0% to 76.6%) of beta(1----6)-linked glucose residues. The alkali-insoluble glucan from yeast and hyphal cells contained from 29.6% to 38.9% beta(1----3) and 43.3% to 53.2% beta(1----6) linkages. Alkali-insoluble glucan from germ-tube forming cells consisted of 67.0% beta(1----3) and 14% beta(1----6) linkages. Branch points accounted for 6.7%, 12.3% and 17.4% of the residues in the alkali-insoluble glucan of yeast, germ-tube forming and hyphal cells, respectively.

High Critical Current Densities in SiC Doped In-Situ ${\hbox{MgB}}_{2}$ Wires Prepared by Continuous Tube Forming and Filling Technique
20 meters long length of in-situ SiC doped MgB2/Fe, MgB2/Nb/Cu/stainless steel (SS) mono- or MgB2/Nb/Cu/Fe multi- filamentary wires with high critical current densities have been prepared by combining both powder in tube (PIT) and continuous tube forming & filling (CTFF) processes. Particular efforts were made in view of the optimization of the manufacturing and annealing processes of the wires. The as obtained mono- wires were sintered under a vacuum furnace and the effects of the sintering temperature on the properties of the MgB2 wires were investigated by the analysis of XRD, SEM and the Jc measurements. The optimized sintering process was found to be 830degC for 15 minutes. It was shown that the magnetic Jc value of MgB2/Nb/Cu/SS wire reaches 6times105 A/cm2 (10 K, 0 T), while the transport Jc value in this 8 at.% SiC doped MgB2/Fe mono- filamentary wire is more than 104 A/cm2 at 4.2 K and a field of 11 T. The estimated Jc value approaches 106 A/cm2 at 4.2 K and zero field. Further enhancement of Jc in both mono- and multi- wires is expected for improving the filling density of the CTFF + PIT processing.

A digital image correlation based methodology to characterize formability in tube forming
This article describes a methodology to characterize the failure limits by necking and fracture, and to determine the critical value of ductile damage in tube forming. The methodology makes use of digital image correlation, thickness measurements and force–displacement evolutions to obtain the strain loading paths and the strain values at the onsets of failure by necking and fracture. The onset of failure by necking is determined by a new technique that combines the strain and force–displacement evolutions whereas the fracture strains at the cracked regions of the tubes are obtained by a similar technique utilized by the authors in sheet metal forming. Transformation of the strain loading paths from principal strain space into the space of effective strain versus stress-triaxiality allows determining the critical experimental value of ductile damage at the onset of failure by necking. The methodology is applied to tube expansion with circular, elliptical and square cross-section punches and results confirm its importance and helpfulness for researchers and engineers involved in the development and optimization of industrial tube forming processes.

FE analysis of tube forming process with experimental verification
Purpose: of this paper: The paper presents some results of extensive investigation of steel seam-welded tubes forming process, by applying combined treatment of material narrowing and expansion. The objective of executed numerical FE and experimental investigations was to determine the optimal technology for production of tubular product at simple tools and at the standard forming processing machines, without defects and with demanded dimensional accuracy. Design/methodology/approach: Tube forming was done in one phase, in tool with two shaping spherical parts, that enables the expansion of the specimen’s central zone and the filling of the die due to narrowing of the specimen ends, when certain conditions are achieved and with appropriate combination of influential process parameters (outer diameter, height and tube’s wall thickness, as well as friction conditions). Series of physical and numerical FE experiments was performed. Findings: Optimal dimensions of tubular product, with required process stability, were obtained this way. Also, results of experiments pointed out that the best process stability and die filling is achieved with specimens whose surfaces had previously been chemically treated. Results of numerical FE simulations of process are quite verified by experiments. Practical implications: Obtained results have practical significance in solving similar processing problems. It also enables to investigate and broaden the knowledge on stability of these kinds of processes, beyond the scope of experimental investigations. Tubular product that is subjected to numerical-experimental investigation in this paper is prepared by narrowing it at both ends thus excluding the possibility to apply holder inside the tube. Originality/value: Proposed method offers possibility for production of tubular products at simple forming machines and tools, without complex and expensive hydroforming equipment.

Least-Square Formulation of the Object Function, applied on Hydro Mechanical Tube Forming
There has been an increasing interest in the area of optimization combined with sheet metal forming in recent years [7] due to the increased robustness of the simulations tools and the increasing computer power, however, the CPU cost and response time are still considerable. The high CPU cost raises the demands for efficient and robust optimization algorithms. The method used in this paper will take advantage of the structure of object function, i.e. formulate the optimization problem as a least square problem, furthermore, Broydens “good approximation” is used to approximate the Jacobian matrix. The performance of the optimization strategy is illustrated by a hydro tube forming example. In order to solve the tube-problem, a method for describing the geometric derivation is needed. The layout for such an algorithm is given in which the ideal geometry is defined as StL-model exported from a CAD-program. The example illustrates the effectiveness of the chosen optimization strategy. For a problem with no less than 6 design parameters, a solution is reached within 31 simulations.

Effect of Various Field Shapers on Magnetic Pressure in Electromagnetic Inward Tube Forming
In this paper,the influence of various field shapers and their shapes on the distribution of the magnetic flux densities and applied forces on the work-piece in the electromagnetic inward tube forming are studied numerically using the FEA software MAXWELL.First the model was verified with experimental results and thereafter four kinds of field shapers(conical,cylindrical,concave and convex)were considered.Effects of their geometries,such as air gap between field shaper and tube work-piece,height of the step in single and multiple stepped field shaper on magnetic flux densities and magnetic pressures were studied.The results of this research can be applied to design field shaper,tube compression technology,and improve the efficiency of the coil.It is seen that magnetic force decreases if height of step in convex field shaper increases but effective forming region enlarges.Decreasing air gap has also a positive influence on magnetic field increase.Though the object of this research is limited to field shaper for inward tube forming,the results can also be applied to the field shaper for tube bulging.

Joining Sheets to Tubular Profiles by Tube Forming
This chapter presents an innovative forming process for joining sheet panels to tubular profiles at room temperature. Finite element analysis and experimentation are utilized to understand the deformation mechanics of the process, to identify the operational feasibility window, and to discuss the capabilities across the useful range of working conditions. The feasibility of the proposed joining process is demonstrated by presenting conceptual applications and industrial prototypes comprising a seat-back bottom frame and an automotive hand-brake system. Results show that joining sheets to tubular profiles by means of tube forming can successfully replace conventional joining technologies based on mechanical fixing with fasteners, welding, or structural adhesive bonding.

Development of a tele-operative control for the incremental tube forming process and its integration into a learning environment
A deficient access to experimental equipment leads to the usage of remote labs to improve engineering education and open experiments for every student location - and time - independent. The usage of a tele-operative controlled industrial bending process in lecture combines theoretical learning contents with practical experiences. Lecturers can make experiments in interaction with the students, who are able to assist in choosing the process values. The chosen and presented bending process is the incremental tube forming process that uses in contrast to many ordinary bending processes targeted the superposition of stresses. By superposing of stresses, in this process for example a tube bending and a tube spinning process, several fundamental process characteristics can be observed and integrated into lectures to visualize the theoretical fundamentals behind. Incremental tube forming combines the tube spinning process, which affects the diameter of the tube all along the tube and creates a compressive stress, and a bending process. The understanding of superposition of stresses and the process phenomena are ambitious, so that experimental experience is very useful. By using a tele-operative control, the experiment is location- and time-independent available for lecturers and students all over the world. They can interact with the process like stopping it, influencing it during the process or laying it up. The possibilities for a usage in learning environments are described and pointed out.

Novel Friction-Assisted Tube Forming Methods: A Comparison of Microstructure and Mechanical Properties
Expanding performance of friction power in material processing techniques, considerably improves the process efficiency while decreases required load and increases imposed strain by the localized material softening. This paper proposes friction-assisted tube forming (FATF) and friction-assisted tube extrusion (FATE) to deform cylindrical tubes for desirable radius and thickness. These methods were successfully examined on commercially pure copper tubes. Finite element (FE) analyses were executed to simulate heat generation, temperature, and strain fields. Using friction power in the presented methods significantly reduced processing force and enhanced imposed strain. Therefore, FATF and FATE show a great capability to forming and extrusion of the cylindrical tubes with minimum processing power. Mechanical properties of the processed tubes showed considerable changes in which yield strength and ultimate tensile strength increased 4.6 and 1.6 times greater than those from the initial values. Dynamically recrystallized fine grains with mean size of 8.3 μm were obtained compared with 60 μm for the annealed sample.
