What Causes Hot Runner Leaks?
Most systems don’t leak because of poor design, but instead because they are operated outside of their designed operating window. […]
General Cleaning Importance in wire EDM
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. […]
Long interval items vary in wire EDM
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. […]
Short interval items vary in occurrence in wire EDM
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. […]
EDM’s Effect on Surface Finish and Integrity
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, […]
Workpiece Characteristics in EDM process
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. […]
How to Incorporate Dual-Rod Technology
an ejector housing cross-section must be designed with the desired plate thickness and necessary ejector stroke. By increasing the lifter core angle, a mold designer can achieve faster part ejection and a larger undercut feature. […]
What is Dual-Rod Lifter Systems?
Use of a second guide rod parallel to the lifter core is a relatively new and under-utilized method. […]
What is Single-Rod Lifter Systems?
When designing mold cores for undercuts and side-action molding, the designer has several lifter system options. […]
Mini hot runner system is very useful
The injection molding of precision and micro parts creates special demands on the moldmaker and hot runner supplier. […]
