Shift work for success – tool coating in injection moulding for precise components

Research laboratory or project work

The goal of the work is the design and application of a tool insert equipped with thermal insulation layers.

Injection molding is the most economical process for manufacturing complex plastic components. The components can only be produced with a high degree of dimensional accuracy if the temperature control of the injection mould is precisely designed. Nowadays, the cooling channel systems in the mold are mainly designed manually and are often not sufficient to adapt the temperature control to the complex geometry of the component. The local application of thermal insulation layers can specifically adjust the cooling rates. The entire heat balance of the mold and the cooling of the moulded part must be considered.
Automated readout methods at the Institute of Plastics Processing (IKV) enable the necessary position and layer thickness to be determined simulatively. The Institute of Surface Technology (IOT) produces the coatings on the tool surface.

The work is related to this research project:

In this sub-project of a special research area, an algorithm is being researched that automatically calculates the optimum cooling of molded parts in the injection mould. This is intended to compensate for part distortion during injection moulding and enable greater part precision.
