Résumé : |
The production costs for complex injection molded parts not only depend on material costs but also to a considerable extent on cycle time. The cycle time is divided into the injection, holding pressure, (residual) cooling phases and the tool movements. The cooling phase takes up 60 to 90 % of cycle time, depending on the particular plastic material and part component. Adequate cooling can therefore reduce not only cooling time but also cycle time. |
