Detecting a hot runner leak can often be difficult, as it is not always readily visible from the outside of the mold. In the worst case, plastic can be seen coming out through the electrical connectors and other openings in the system. […]
There are various nozzle design options to seal between the manifold and the nozzle – (1) the solid skirt design with no active leakage prevention feature; […]
Most systems don’t leak because of poor design, but instead because they are operated outside of their designed operating window. […]
Good cleaning habits and care of a wire EDM machine is highly recommended. Regular and systematic cleaning of the machine also can extend the life of some consumable items. Care should be taken when selecting a cleaner. […]
1) Machine Filters: Replacement of the main water filters will be required and should be performed as needed (most machines will typically generate an alarm when the filters are depleted). Replacement intervals are purely dictated by the type of work, workpiece material and thickness, and applications being performed. […]
1) Automatic Wire Threading System: The automatic wire threading (AWT) system performs the threading of the wire via a water jet column. It is the single most important automated feature on a wire EDM machine. […]
Surface finish and integrity are two different facets of the cavity quality, but both play an important part in the characteristics of the mold. Much as the machine parameters affect the integrity of the sub-layers of the cavity, […]
The spark intensity is not the only determining factor affecting the surface integrity. This also is dependent on the thermal conductivity of the work metal. High thermally conductive metals will usually have a smaller white layer and less microcracking than a lower conductive material. […]
Today’s marketplace demands short schedules and innovative designs that push the envelope on existing manufacturing techniques. […]
Remember that on some projects a design consultant may prefer to pre-select a moldmaker or molder in order to meet a tight schedule or to ensure they have specific technical skills. […]
