Mechanical Solution Enables Simpler Extraction of Undercuts

Ermanno Balzi S.r.l’s AnglePro is a mechanical solution that enables the extraction of undercuts with a reduced extraction stroke compared to traditional systems. This result is made possible by a chain sliding system that, starting from a vertical push of the extraction plate, enables the movement of the extraction rod at angles up to 35°.

Considering that maximum extraction angles of 12° are normally used with single-rod systems and up to 18° with double-rod systems, with its 35°, AnglePro can significantly reduce the ejection stroke, thereby decreasing the mold height and the opening required between the fixed and movable parts for the ejection of the molded part.

Since mold height is often a key factor in choosing the IMM on which to mount it, AnglePro enables the use of smaller IMM, thus reducing the production cost of the molded part.

With AnglePro, it is also possible to extract undercuts with delay and advance angles up to 35°, while keeping the fixing system in the ejection plate unchanged, which provides a seat similar to that of an ejector pin. Advance and delay are achieved simply by tilting the chain links, with one-degree intervals, without any modification to the external system.

According to the company, the 3D configurator makes it is easy to identify the most suitable AnglePro model for a specific application and download its 3D model in the desired format.
