Résumé :

The use of exposed cement materials as wall finishing lately is in great demand and is becoming a designtrend at the moment. Many property buildings ranging from commercial buildings such as cafes, restaurants,to hotels to residential buildings such as houses, apartments and condos use exposed cement as one ofthe interior wall finishing. Exposed cement as wall finishing is usually associated with industrial designstyles. In Indonesia, exposed cement is applied as finishing material after bricks. Using exposed cementas wall finish that nowadays has been trending in architecture and interior applicants gives a differentambience of space, home or building yet still economically acceptable. The using of exposed cement aswall finish are close to the using of industrial style. As known, industrial style is an interior architecturedesign style that adopting industries elements such as the using of metal, bricks and pipe material thenbe exposed on purpose. Industrial style has color palette such as black and greyish. Therefore the usingof exposed cement as wall finish often used in industrial design style. However with the popular use ofexposed cement as wall finish does not mean that it can freely acceptable in all situations, because it canaffect the comfort of the room user.

Résumé :

A new technology for Cr(VI) and divalent metal ions removal based on metal sorption onto exhausted coffee waste has been developed. Physical and chemical characterization of exhausted coffee waste was explored as well as the role of structural and non structural compounds of the waste in metal ions sorption. Kinetics of Cr(VI) sorption from binary mixtures containing different Cr(VI) and Cu(II) molar ratios were carried out in a batch reactor. A synergistic effect of Cu(II) in Cr(VI) reduction and sorption was found. From the kinetic sets of data a kinetic model taking into account Cr(VI) reduction/sorption, reduced Cr(III) sorption and Cu(II)synergistic effect on sorption was developed. The model described quite accurately the overall process of Cr(VI) removal. Biosorption by coffee wastes followed by precipitation resulted to be an efficient and low cost technology to remove Cr(VI) and divalent metals from synthetic and industrial effluents from metal finishing industries

Résumé :

Environmental legislation is becoming more stringent as people are realising the need for conservation and a reduction of environmental degradation in order to facilitate sustainable development. To ease legislative pressures, companies need to work together in symbiotic networks, whereby co-operation between companies results in far more innovative practices than if the companies acted individually. Success in an industrial network is largely dependent on cleaner production, where industries seek to redirect from waste treatment to waste minimisation. Cleaner production has already received international recognition and waste minimisation initiatives have been used as a tool of cleaner production. Two polluting industrial sectors within South Africa, the textile and metal finishing sectors, were chosen to investigate waste minimisation concepts. One company from each sector was used as a case study. The dissertation followed company network identification, potential to participate within an industrial symbiotic network, and waste minimisation opportunities. Suppliers and buyers, up and down the product line were identified. Relationships with these partners should be advanced such that environmental concerns are at the forefront of any decision-making. In light of developing industrial networks and maintaining symbiotic relationships, the company's potential was investigated by interviewing employees of various ranks. Both companies were partially suited to participate within an industrial symbiotic network and company-specific barriers were identified, such as ineffective internal communication. The waste minimisation investigation followed a four-phase approach of planning and organisation; pre-assessment; assessment; and feasibility study. In both the companies investigated, water savings were identified as the waste minimisation focus area with potential for improvement. In total, potential water savings of over R80 000 per annum were identified. In the textile company, the weaving department and bleach house were further investigated. Cloth weaving errors were attributed to machine stops, as each stop has the potential to result in a cloth fault. In the bleach house the potential existed to reduce the number of rinse tanks. Although a modem and automated process, the plating plant in the metal finishing company was identified as having potential waste minimisation opportunities. Of particular interest was the reduction of solution carry over from the plating tanks into subsequent tanks. Extended drip times were investigated. Additional waste minimisation opportunities included repairing pipe leaks, replacing the degreasing solvent, trichloroethylene, with a less harmful cleaning agent and establishing a symbiotic relationship with the oil supplier, Castrol. Over and above the main waste minimisation opportunities highlighted, other recommendations and potential savings were identified. Each case study emphasises that simple waste minimisation initiatives, without expending capital, reduce demands on natural resource, such as water, and benefit the company financially. Successful waste minimisation leads to further cleaner production initiatives, which may then initiate better network interactions with the further potential of promoting sustainable development.

Résumé :

AbstractIn the present study, the adjoint method is introduced to the optimisation of the corner cooling element in two baseline cooling designs for a mould cavity, as examples of the Aluminium metal die-casting process. First, a steady thermal model simulating the Aluminium die-casting process is introduced for the two-corner cooling design scenario. This steady model serves as the first iteration of the optimised model using the adjoint method. A dual-parameter objective function targets the interfacial temperature standard deviation and pressure drop across the internal cooling region. For both design cases, multi-iterative deformation cycles of the corner cooling configurations result in optimised designs with non-uniform cross-section geometries and smooth surface finishing. Numerical simulations of the resulting designs show improvements in uniform cooling across the mould/cast interfacial contact surface by 66.13% and 92.65%, while the optimised pressure drop increases coolant fluid flow by 25.81% and 20.35% respectively. This technique has been applied to optimise the complex cooling system for an industrial high-pressure aluminium die-casting (HPADC) tool (Zeng et al. in SAE Technical Paper 2022-01-0246, 2022, [1]). Production line experience demonstrates that the optimised designs have three times the operational life compared to conventional mould designs, providing a significant reduction in manufacturing and operation costs.

Résumé :

Faraday Technology, Inc. has developed electrochemical techniques for the edge and surface finishing of advanced materials, such as titanium alloys, stainless steels, and nickel based superalloys. This technology employs electrochemical metal removal under the influence of a bipolar, pulsed electric field to provide enhanced process control and excellent surface finishes. This process achieves high rates of metal removal in the presence of simple chemistries that are pH neutral, water based, non-toxic, and environmentally benign. This is in contrast to competing technologies that rely on electrolytes that are comprised of concentrated acids or ethylene glycol. This paper will present Faraday’s recent development efforts in a wide variety of industries, including the semiconductor, automotive, and medical industries.

Résumé :

This paper presents some practical considerations on finishing of parts made by direct metal laser sintering (DMLS). The main process capabilities limitations of this promising rapid tooling technique are in fact in the surface roughness of the produced parts. This fact hinders the introduction of DMLS as a widely employed industrial process, especially for what concerns the production of moulds and inserts and allows their use only as preseries tools in injection moulding of plastics, since the requirements for preseries tools are worse than those needed during the process. Barrel finishing, in turn, is a well established technique to improve the roughness of parts of complicated shape by means of a soft mechanical action over the surface. The results herewith presented show that it is possible to achieve roughness of the order of 1 μm Ra even when starting from initial roughness of the order of 15 μm Ra, i.e. those typically attained by DMLS.

Résumé :

A numerical strategy to determine an estimate to the optimal initial distribution of temperature for industrial processes requiring coiling of bars in hot metal rolling operations based on a three-dimensional mathematical model for the evolution of temperature in a shape changing domain is presented. The corresponding numerical solution is presented as well. The solution integrates a two dimensional geometrically adaptive finite element solution in the coiling plane for a shape changing domain with a finite difference one-dimensional solution in the widthwise direction of the bar using a novel numerical separation of variables strategy. Time is discretized according to a Crank-Nicolson type scheme. The results of a specific numerical study for the coiling of hot steel between the roughing stands and the finishing stands are presented.

Résumé :

The use of a rapid manufacturing method to create injection mould tools offers the opportunity to create conformal cooling channels in the core/cavity inserts. Conformal cooling channels allow for better thermal management of the injection mold tool through the cycle, with the potential to reduce cycle times and/or improve product quality. However, currently available rapid manufacturing methods do not deliver the levels of accuracy and surface finish required to meet typical injection mould tool specifications. This paper reports on a hybrid approach to developing the mold inserts, which uses the rapid manufacturing process of indirect selective laser sintering (SLS), using the 3D Systems LaserForm process, to create a near net shape insert with conformal cooling channels, and then produces the net shape inserts by using high speed machining (HSM) as a finishing process. This approach to injection mold tool development has been tested through three industrial case studies. In each study existing injection mold inserts have been redesigned to give a conformally cooled tool. These have then been manufactured to near net shape in a steel/bronze metal composite through indirect SLS, and finished to production specification using HSM, EDM and polishing. Within the case studies the main aim has been to improve productivity, and the inserts have been evaluated in industrial trials in order to assess their performance in terms of cycle time, energy usage, durability and quality. The results show that significant productivity improvements and energy use reductions in injection molding are possible through the implementation of conformal cooling. Consistency of part quality and material durability have been assessed through extended molding trials, and in some cases there is a clear economic benefit to using the inserts. However, the importance of up front modelling to understand the impact of conformal cooling channels, the need for careful planning in manufacture to ensure that the required internal geometry is created, and the need for multiple representations of the required geometry to inform the different stages of the manufacture process are highlighted.

Résumé :

The leather industry creates a product that is both natural and long lasting. Leather is unique in its ability to combine beauty, comfort and practicality. Finishing, the last operation in natural leather processing, determines the appearance and value of the finished product, and has the purpose of embellishment, providing lustre and pleasant feel, covering flaws and forming a surface layer that protects leather during wear while improving resistance to external factors. The quality of the pigment pastes used in the composition of the leather surface finishing films influences some of the physical-mechanical, technological and aesthetic properties of the finished products. The materials for finishing – pigment pastes with aesthetic effect – were obtained based on dioxide-titanium, metal pigment-aluminum, polymeric binder, lauryl alcohol ethoxylated with 7 moles of ethylene oxide, waxes and plasticizers and were characterized by physical-chemical, microscopical, spectral and rheological analyses. Pigment pastes with metallic effect were used in combination with film forming acrylic and polyurethane polymers, with high resistance to light and aging for finishing natural leathers, with applications in creative industries (modern footwear).

Résumé :

Leather has a natural beauty that, unlike many materials, improves with age, and has long been a component of luxury goods such as footwear, leather goods and clothing. It is a natural and durable material, unmatched by any synthetic product, in terms of hygienic and protective properties. Thanks to the skills of leather producers, who take the same basic raw material, natural leathers are processed through different technological processes and transformed into finished leathers for various clothing items with high-performance properties. Finishing is achieved through a series of technologies, using materials that provide the finished leather with the desired aesthetic characteristics related to fashion, colors and special effects (pearl, two-tone, antique, printed, glossy, matte, waxed, etc.). Hand-painted natural leather shoes are also in fashion, to give a personal touch to a luxury item. The work presents surface finishing technologies of ecological natural leathers (tanned without metals), using pigment pastes with a metallic effect, in combination with acrylic and polyurethane polymers, with resistance to light and aging. White and pastel finished leathers with silver and gold effect can be used in creative industries for artistic and luxury footwear (especially for women).

Résumé :

Direct Metal Laser Sintering (DMLS) is an additive manufacturing technology that can construct medium to small size parts very efficiently in comparison to traditional machining processes. The ability of this technology to grow complex parts made of high strength titanium- and nickel-based alloys led to increasing interest from aerospace, defense, and medical industries. Although the technology allows growing parts close to their final shape, the active surfaces still need a finishing operation such as grinding to meet the tight tolerances and surface finish requirements. Due to the novelty of the DMLS technology, and the relatively recent developments of titanium alloy powders, there is a need for testing and validating the capabilities of the components manufactured through a combination of DMLS and grinding processes. This paper presents the findings of an experimental study focused on the effect of various grinding conditions on the surface integrity of titanium alloy (Ti-6Al-4V) specimens produced using DMLS technology. The goal is to identify dressing and grinding conditions that would result in ground surfaces free of defects such as micro-cracks, discoloration of surfaces and/or burn marks due to high heat generated during grinding. The residual stresses were used to quantify the effect of the grinding conditions on the ground surfaces. These investigations were conducted on an instrumented CNC surface grinding machine, using a silicon-carbide grinding wheel and a water-based fluid. The X-ray diffraction method was used to measure the residual stresses. Two batches of specimens were manufactured for these tests. The growing strategy of the specimens and the presence of apparent defects in material structure are considered some of the main causes for the differences observed in the outcomes of the grinding trials.
