Important processing technology of precision mold Mold Collapsible Core

In addition to high enough strength and toughness, the surface properties of high-precision Mold Collapsible Core are very important to the working performance and service life of high-precision mold parts.

The improvement of these properties is very limited and uneconomical simply relying on the improvement and improvement of the matrix material, but through the surface treatment technology, it is often possible to get twice the result with half the effort.

It is worth noting that the surface polishing of Mold Collapsible Core is not only affected by the polishing equipment and process technology, but also by the mirror surface of the mold material, which has not received enough attention, that is, the polishing itself is restricted by the mold material. Although new processing technologies aimed at improving the surface properties of precision mold parts are constantly emerging, nitriding, carburizing and hard film deposition are the most widely used in the manufacture of high-precision mold parts.

Because the nitriding technology can form a surface with excellent performance, and the nitriding process has good coordination with the quenching process of high-precision mold parts steel, and the nitriding temperature is low, and no intense cooling is required after nitriding, and the deformation of high-precision mold parts It is extremely small, so the surface strengthening of high-precision Mold Collapsible Core is the earliest and most widely used nitriding technology.

Mold Collapsible Core polishing technology is an important part of mold surface engineering and an important post-processing process in mold manufacturing.
