In this webinar, we will discuss how plasticization affects the quality of the injection-molded part and what visible defects may occur as a result.

In this section, we will focus on injection instabilities that arise during the cavity filling phase, which stem from the nature of the plastic melt.

How accurate are Moldflow analysis results? The results are only as accurate as the input data provided.

Very often, injection-molded parts have thin walls that are difficult to fill. We will demonstrate the influence of cavity pressure on their filling.

Sink marks are visible defects on the surfaces of injection-molded parts. A more severe stage are voids, unwanted cavities within the walls of injection-molded parts.

Sink marks are visible surface defects on injection-molded parts. A more advanced issue are voids—undesirable cavities within the walls of injection-molded parts.

This webinar follows webinar No. 6 Injection inhomogeneities during packing – shrinkage, anisotropy, tolerance.

The cost of plastic and cooling time can account for more than 70% of the part production costs.

The cost of plastic and cooling time can make up more than 70% of the production costs of a part.

Residual stresses are mechanical stresses that develop in the injection-molded part during the individual phases of the injection molding cycle.

Residual stresses are mechanical, residual stresses generated in the injection-molded part during manufacturing.

Residual stresses are mechanical, residual stresses generated by internal forces in the injection-molded part during the injection molding cycle.

Shrinkage cavities are unwanted voids in the walls of injection-molded parts. They affect the appearance of the part as well as its mechanical properties.

Uneven filling of a cavity or cavities in injection molds is a phenomenon that everyone involved in injection molding technology has certainly encountered.

The cost of plastic and cooling time often make up more than 70% of the cost of manufacturing a part.

Residual stresses are mechanical stresses that develop in an injection-molded part due to internal forces. They are generated mainly during the injection molding cycle. These stresses remain embedded in the molded part even after ejection from the mold cavity.
