The aim of the study is to investigate the extent to which the quality performance will be changed by transferring the processes in the coating section of the home textile production enterprise to the automation system. The effects of total quality on the efficiency of companies were investigated. The supporting role of total quality management with information communication technologies is examined. For this purpose, an intermediary model has been created. The data were obtained from the employees of the coating department of a company operating in the textile sector. As a result of the analysis of the model, the full mediation role of TQM applications in relation to TQM-ICT awareness and quality performance was determined. [ABSTRACT FROM AUTHOR]

Electrophoretic deposition plays a major role in many industrial coating processes. However it is observed that the usage of the standard electrophoretic deposition process with one counter electrode leads to an inhomogeneous layer thickness distribution on the workpiece. In this article it is shown by numerical methods that segmented counter-electrodes with individual potential differences can be successfully used to reduce the amount of coating material in the process. For the optimisation an efficient mathematical model with a thin layer approximation is introduced. Therein it is especially necessary to model the effect of the deposited layer on the applied electric field. So the aim of this work is on the one hand, to extend the existing models to arbitrary non-planar geometries in three space dimensions, and on the other hand to apply this model for the optimisation of industrial coating processes.

At the paper it is reported the effect of coated factor in the behavior of coated tubular electrodes for hardfacing by SMAW of components of the sugar industry, as to consumption parameters and the geometry of the deposited metal. The electrodes were made with different coating thickness for a fixed diameter of the metal tube and coating composition, in order to value the exclusive influence that the thickness has. Each coating factor (relation between the total diameter of the electrode and the diameter of the metal tube) was evaluated as a function of the variation in welding current. Deposits over the metal plate were made, letting evaluate the geometrical dimensions of the welding bead and the consumption parameter of electrodes. Was concluded that for those electrodes the value of the coating factor have to be 1,2 and showing the best integral performance for the hardfacing of pieces around an average welding current of 100 A.

Abstract: Coated tools constitute the majority of the tools applied in material removal processes, rendering the employment of uncoated ones as an exception. A broad growing market of coated cutting tools has been developed. Moreover, numerous material- and manufacturing-engineers have joint their expertise, aiming at developing coatings meeting the needs for processing the most difficult-to-cut materials at the most extreme cutting conditions. The emerging of new workpiece, tool and film materials, the evolution of sophisticated coatings’ characterization methods and the continuous need for higher productivity rates, maintain vivid the industrial and scientific interest for further advancing this field.

We consider a complex planning problem in integrated steel production. A sequence of coils of sheet metal needs to be color coated in consecutive stages. Different coil geometries and changes of colors necessitate time-consuming setup work. In most coating stages one can choose between two parallel color tanks. This can either reduce the number of setups needed or enable setups concurrent with production. A production plan comprises the sequencing of coils and the scheduling of color tanks and setup work. The aim is to minimize the makespan for a given set of coils. We present an optimization model for this integrated sequencing and scheduling problem. A core component is a graph theoretical model for concurrent setup scheduling. It is instrumental for building a fast heuristic that is embedded into a genetic algorithm to solve the sequencing problem. The quality of our solutions is evaluated via an integer program based on a combinatorial relaxation, showing that our solutions are within 10% of the optimum. Our algorithm is implemented at Salzgitter Flachstahl GmbH, a major German steel producer. This has led to an average reduction in makespan by over 13% and has greatly exceeded expectations.
