  RAW MATERIALS SELECTION:- The selection of raw material plays a predominate role & it is an important criteria in tooling. At the same time improper selection may affect an adversely on many factors such as mould life, quality of mould, cost of the mould etc.               The raw material used for this tool is steel. The raw material chosen for each part has its own function to perform .  Raw   material   selected usually   depends on   the   functional   aspects   of   the   part   that   it   serves. In general material selected should have the following characteristics: 1.            High resistance to heat. 2.            Sufficient toughness and hardness. 3.            Dimensional stability during heat-treatment. 4.            Good polishing properties.  5.            High thermal conductivity. Elements and their influence: Carbon:   Increase strength, elasticity and hardness.  It lowers the ductility and impact strength.  An  important  fact  is  that  abo

  Two Cavity mould About this project :- This project gives detailed knowledge of mould making and designing in step-by-step and also difficulties involved and skill of the Toolmaker AIMS of Project :- The aim of project report is to explain the tool making Processes from foundation to the finish in a simpler and clear manner. INTRODUCTION to MOULDS Mould is a tool, designed to form the component with desired shape and size. The type of material to be moulded and the shape of the component are the major factor governing the choice of the mould.  Moulding of plastic material comprises of forming an article to the desired shape by the application of heat and pressure in a hollow form or cavity. Mould is a hollow form of cavity into which molten plastic materials is forced to give the shape of the required components. The terms generally refers to the assemble of parts which go top make up the section of the injection moulding equipment’s in which plastics components are moulded. INTRODU
