Competency aims

To understand the planning of a product between a part with undercuts, tool design with cammed mould and manufacturing injection techniques. To exercise
different structure solutions and to document a work to a technical documentation whit a table of contents.

Learning outcomes

At the end of the course the student is expected to be able to design a mould with different partliness, with several undercuts and cammed molds.

  • To bee able to use standardized constructions to fulfill complicated structure.

Course contents

  • Materials to a product with different undercuts.
  • Injection moulding processes.
  • Use of standard components of cammed molds for part with undercuts cams moved in vertical direction when a mold is opened.
  • To define the partlines of a product with undercuts.
  • Hot and cold runner systems.
  • Mould design guidelines of a cammed mould (runner design, part thickness, and drafts).
  • Cammed mould standards and components.
  • Ejector systems in a cammed mould system.
  • Cooling systems of cammed moulds
  • Use of mold flow software.
