Affecting processing and properties of injection moulded thin-wall parts using dynamic tempered Rapid Tooling moulds

Affecting processing and properties of injection moulded thin-wall parts using dynamic tempered Rapid Tooling moulds

In injection moulding of thin-wall parts the fast cooling velocity leads to a modified inner structure as well the shear and elongational flow to high molecular orientations. This results in significant anisotropy of mechanical properties. Especially the latter can lead to a significant anisotropy of the part properties. This work deals with Rapid Tooling moulds show that adapted mould temperatures during injection moulding favour the homogenization of the crystalline structure and molecular orientations respectively. In particular, a delay of cooling after melt injection allows a significant reduction of molecular orientations. Consequently, the adjusted processing conditions affect the local mechanical properties in a molded part.
