Laminate Tooling for Injection Moulding

Abstract

The main goal of this research was to develop a method of prototyping injection moulded parts which produces a representation of the production part, including not only the part shape and functionality but the process as well. A prototyping method that meets all of these requirements could greatly aid in reducing the time required to bring a new product to the market by using the information gained from this prototype to manufacture a production tool that will be right the first time. Tooling constructed of laminations is appealing for prototyping or production because of the flexibility it affords in terms of rapidly altering mould geometry, gating or cooling passage design. This report summarizes a ‘proof of concept’ project which took a selected part geometry through the entire laminate tool manufacturing process. This report is divided into five sections: (1) introduction to the prototyping process, (2) background of current prototyping processes and description of the laminate tooling method, (3) description of the geometry selected for this work and the manufacturing details, (4) evaluation of the performance of the laminate injection mould and (5) conclusions.
