Manufacture of Moulds

—-

In theoretical-practical classes are presented the contents that allow know the different types and components of the moulds and polymeric parts produced. In this way, are presented videos, photographs, technical drawings, different standard components of moulds and some moulds that exist in the Mechanical Engineering department.
They are also presented and discussed in detail different polymeric parts produced by injection.
In laboratory classes is produced, by injection, different polymeric parts made with different thermoplastic base materials. It is also designed and drawn a mould.
It also carried out a study visit to a manufacturing mold company.

Identify the main types of moulds used in the industry;
Know the thermoplastic injection cycle and the main parameters of the process;
Know the main machining processes used in the manufacture of moulds and establish the relationship between geometry and the most appropriate procedure for obtaining them;
Select materials and heat treatments applied in thermoplastic injection moulds;
Know the functional systems of thermoplastic injection moulds and the main standard elements that exist in the market;
Apply the specific rules of project, design and manufacture in thermoplastic injection moulds.
