Abstract(s)

This document is the internship report of the Master in Product Design Engineering carried out at Tecnimoplás Lda. The company Tecnimoplás Lda is dedicated to manufacture of molds. They have an ability to make a small, medium and large size molds. Tecnimoplás is a company started in 1971 based in Marinha Grande, specialized in the service of mold. With this internship it was possible to get the industrial immersion that was the one of the objectives of the student for this stage. In the company after an initial inclosing, it was possible to develop work in the different equipment’s with different materials for mold in the company machines. This statement is a detailed description and analytical analysis with various processes to make a mold. In this process one of the main process is Deep Hole Drilling. It is also talking about the various types of tools used in deep hole drilling machines and also discuss about the various types of fixing system in deep hole drilling machines. This deep hole drilling is mainly used for Water and Oil circuit in the mold. This report also comprises of case study of Deep hole drilling process and the void formation in the parts of Deep hole drilling machines. This work also concluded that it is fundamental that the tools used in Deep Hole drilling, are used within the ranges of operation recommended by the tool’s manufacturers.
