Achieve One-Time Success in Molding

Select the Suitable Machine Based on the Shape and the Size of Parts

In order to achieve the effect of "molding without repairing" in mold parts assembly, the accuracy of each part needs to be qualified when it is finished, and high-precision equipment is the basic guarantee of this.

2-5μm Precision Electrode Machining
5-15μm Mold Parts Processing

JINGDIAO Proven Precision Machining Solutions

Mold parts are qualified when finished requires not only a high-precision equipment, but also a proven and stable machining process.

With JINGDIAO proven precision machining solution, it can realize that “molding without repairing” when assembling 83 mold parts processed in JINDIAO high-speed machining center and 212 standard parts. The key is to digitalize the proven machining process, such as the digitization of tool parameters in mold parts processing, including tool selection, tool parameter setting and tool wear control.
