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. […]
In moldmaking applications, High Energy Applied Technology (H.E.A.T.) can be used very effectively to cut inserts, core pins and insert pockets that contain contours and changing surface thicknesses. […]
High Energy Applied Technology(H.E.A.T.) has been tested against other major EDM brands. In almost every case, it has been proven to burn at least 15 percent faster, produce part straightness of .0005 inches in one roughing pass and .0002 inches with one rough and one skim, in parts up to 12 inches tall, and provide [...]
High Energy Applied Technology (H.E.A.T.) was developed to address the need for high-speed cutting of wire EDM applications where good, sealed flushing cannot be achieved, while at the same time providing high accuracy, unparalleled part straightness, and good surface finishes. The desire to be able to use the most common EDM wires in today’s market [...]
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, they also affect the surface finish. […]
Wire-making dies have a hole through the middle of them. A wire or rod of Steel, copper, or other metals or alloy, enters into one side and is lubricated and reduced in size. The leading tip of the wire is usually pointed in the process. The tip of the wire is then guided into the [...]
Die operations are often named after the specific type of die that performs the operation. For example a bending operation is performed by a bending die. Operations are not limited to one specific die as some dies may incorporate multiple operation types… […]
Forming dies are typically made by tool and die makers and put into production after mounting into a press. The die is a metal block that is used for forming materials like sheet metal and plastic. For the vacuum forming of plastic sheet only a single form is used, typically to form transparent plastic containers [...]
The earliest examples of die casting by pressure injection – as opposed to casting by gravity pressure – occurred in the mid-1800s. […]
Die casting vs. plastic molding – Die casting produces stronger parts with closer tolerances that have greater stability and durability. Die cast parts have greater resistance to temperature extremes and superior electrical properties. […]
