A 1:1.5 acceleration ratio achieves a longer path with a small stroke.

New compact ejector accelerator reliably demolds complex injection molded parts

The new E 1522 Ejector accelerator from Meusburger (Wolfurt, Austria) optimizes the smooth ejection of injection molded parts and promises safe and targeted ejection of complex parts. The acceleration ratio is 1:1.5, achieving a longer path with a small stroke. Through the additional acceleration of a single ejector, “snagging” of the injection molded part is avoided.

The repositioning of the accelerator does not take place directly through the clamp plate but through a cut-to-length ejector, so the same buffer plates for the ejector set can be used. A further advantage is that the entire injection pressure is absorbed directly by the ejector base plate. As a result, the ejector accelerator does not bear any load during the injection molding process, explained Meusburger.

Three different sizes allow designers to install ejectors in diameters of 3 to 11.5 mm at will. The small component size enables flexible positioning of the ejection accelerator in the ejector set, allowing quick and easy retrofitting. In order to save design time, the installation space is already included in the CAD data. The new component is available from stock.
