“…The die and mold industry plays a significant role in the manufacturing world [1]. This is due to the fact that nearly all mass-produced parts are manufactured employing processes that include dies and molds, directly affecting not only the efficiency of the process, but also the quality of the product [2].…”

Hot stamping dies include cooling channels to treat the formed sheet. The optimum cooling channels of dies and molds should adapt to the shape and surface of the dies, so that a homogeneous temperature distribution and cooling are guaranteed. Nevertheless, cooling ducts are conventionally manufactured by deep drilling, attaining straight channels unable to follow the geometry of the tool. Laser Metal Deposition (LMD) is an additive manufacturing technique capable of fabricating nearly free-form integrated cooling channels and therefore shape the so-called conformal cooling. The present work investigates the design and manufacturing of conformal cooling ducts, which are additively built up on hot work steel and then milled in order to attain the final part. Their mechanical performance and heat transfer capability has been evaluated, both experimentally and by means of thermal simulation. Finally, conformal cooling conduits are evaluated and compared to traditional straight channels. The results show that LMD is a proper technology for the generation of cooling ducts, opening the possibility to produce new geometries on dies and molds and, therefore, new products.

Accepted: 2 September 2017 Thailand hosts over 50 percent of the world's top OEM automotive parts suppliers and additionally is home to over 2,400 Tier 1-3 manufacturers and suppliers. Given the significance of these numbers and Thailand's leading ranking and contribution to the global automotive industry, research was undertaken to determine how manufacturing clusters and innovation capability effect competitive advantage as it relates to automotive production part management. Multiple objectives were established which included the study of the effects and overall influences of the various variables on competitive advantage as well as the development of a structural equation model (SEM) to define how innovation and manufacturing clustering affects the competitive advantage within the Thai automotive parts molding sector. Quantitative methods analysis was conducted on the data from 240 automotive production and components suppliers' questionnaires collected from industry managers with the research results partially obtained from the analysis by use of (PLS)-graph. Qualitative research was also obtained by use of purposive sampling from in-depth interviews from ten senior managers. The results obtained indicated that clusters and innovation capability has a significant and positive effect on competitive advantage. Thus, the findings from the research illustrate that if an organization focuses on clusters, there will be a knock-on effect within the automotive parts groups leading to the increase in innovation capability, which creates a greater competitive advantage, not only for the enterprises, but also for Thai society as well.

Subject reviewThe forging dies are parts, which are operating at elevated temperatures, while simultaneously subjected to variable loads that can be compressive -even impact and shear. Impact of the hard facing technology is very strong since varying of the hard facing parameters directly affects the output characteristics of the hard faced layers. The criterion for estimating that impact was based on results of performed tribological investigations. The tribological parameters that were monitored were the friction coefficient, the wear scar/trace width and the wear area of the hard faced layers, with the two different types of lubricants. Hard facing technology implied selection of the welding process, filler metals, preheating temperatures and other parameters of the hard facing process. The influence of the proposed hard facing technology was determined by monitoring hardness, microstructure and wear resistance of the executed joints after the hard facing and after tempering. The objective of this work was to establish the correlation between the selected hard facing technology, filler metals and applied heat treatment on mechanical and tribological characteristics of the executed hard faced layers. Keywords: forging dies; friction coefficient; hard facing; hardness; microstructure; wear resistance Utjecaj tehnologije navarivanja i dodatnog materijala na tribološke karakteristike navarenih kovačkih alataPregledni članak Kovački alati su dijelovi, koji rade na povišenim temperaturama, dok su istodobno izloženi promjenljivim opterećenjima, koja mogu biti tlačna -čak i udarna i smična. Utjecaj tehnologije navarivanja je vrlo jak, pošto se variranjem njegovih parametara direktno utječe na izlazne karakteristike navarenih slojeva. Kriterij za procjenu tog utjecaja bio je utemeljen na rezultatima obavljenih triboloških ispitivanja. Praćeni tribološki parametri bili su faktor trenja, širina traga (brazgotine) habanja kao i površina habanja navarenih slojeva, uz uporabu dva tipa maziva. Tehnologija navarivanja je podrazumijevala selekciju procesa zavarivanja, dodatnih materijala, temperature predgrijavanja i ostalih parametara procesa navarivanja. Utjecaj predložene tehnologije navarivanja je određivan praćenjem tvrdoće, mikrostrukture i otpornosti na habanje izvedenih spojeva, nakon navarivanja i nakon otpuštanja. Cilj ovog rada bio je uspostavljanje korelacija izabrane tehnologije navarivanja, dodatnih materijala i primijenjene toplinske obrade s mehaničkim i tribološkim karakteristikama izvedenih navarenih slojeva.
