“…Isto posto, como o lean visa eliminar perdas ao longo do processo, Slack et al (2013) Ademais, o Lean requer uma melhoria contínua que possibilite a manutenção de práticas enxutas (Władysiak, 2006), baseado no fato de que o objetivo é limitar os tipos de desperdício em todas as áreas do empresa (Sokovic, Pavletic & Fakin, 2005). Assim, a manufatura adaptada segundo os conceitos lean, na visão de Modi & Thakkar (2014) podem apresentar vários benefícios, como:…”

O pensamento lean pode ser traduzido como um conjunto de princípios, ferramentas e técnicas que, combinadas, objetivam a melhoria, em termos de qualidade, custo, satisfação do cliente e outros. Diversas ferramentas e métodos podem auxiliar as organizações na busca por um ambiente fabril “enxuto”, desde por exemplo ferramentas da qualidade, tecnologia da informação e ainda, métodos matemático-estatísticos, como a previsão da demanda. Assim, o presente artigo que comporta-se como estudo de caso, teve como objetivo analisar a aplicação do modelo de Holt-Winters para Efeitos Sazonais Aditivos, numa empresa fabricante de polpa de frutas localizada em Pernambuco e comparar os ganhos obtidos sob a ótica da filosofia lean. Observou-se, entre outros ganhos, menor nível de estoques, tempo de espera reduzido e ainda menores custos. Ou seja, comprova-se que, quando aplicada a técnica de previsão da demanda, a gestão da empresa pode planejar melhor suas aquisições, determinar investimentos em ativos, contratação de mão de obra, ampliação da capacidade produtiva e ainda, estimar lucro da mesma.

“…Due to the potential applications of Al-Si alloys where high mechanical and thermal loads are involved (e.g. pistons, cylinder heads, brake calipers and engine parts), an alloy with high corrosion resistance, good mechanical properties and dimensional stability at different operating temperatures is required [1][2]. Investigation of castings with thermal stresses for automotive driveline components has been carried out by authors [3][4][5], where they focus, for example, on the assessment of mechanical properties at high temperature and improvements are achieved by adding Mn or Ni.…”

The paper deals with the possibilities of influencing the final microstructure of aluminium alloy castings by changing the external conditions of crystallization and solidification. Aluminum alloys, especially Al-Si alloys, are nowadays one of the most used non-ferrous metal alloys, especially due to their mass application in the automotive field. It is in this industry that extreme emphasis is placed on the quality of cast parts with regard to safety. For this reason, a key production parameter is the mastery of the control of the resulting microstructure of the castings and the associated internal quality, which is subject to high demands defined by international standards. The aim of the experiment of this paper is to evaluate the effect of different preheating of the metal mould on the resulting structure and hardness of test castings made of AlSi7Mg0.3 material. The hardness measurement will be evaluated on a hardness tester. The parameter SDAS, Microporosity, Content of excluded eutectic will be evaluated. Dependencies will be found and plotted.

Purpose The lean manufacturing (LM) approach is a highly effective method that can be implemented in any industry to streamline production processes, meet customer demand and eliminate any unnecessary waste. This paper aims to propose and evaluate a generic project-based framework grounded on the LM approach for reducing lead time in foundry processes. Design/methodology/approach Using design science research (DSR), we developed a generic LM project-based framework for reducing lead time in foundry processes. Findings The developed framework provides an alternative method to implement LM projects to reduce lead time and nonvalue activities in foundry factories. Practical implications The findings of this research can guide better lean practitioners for lead time reduction in foundry processes. Originality/value This paper contributes to the operational excellence literature when discussing the impact of the LM approach on foundry processes. In addition, the paper provides a roadmap for reducing lead time in a foundry company.
