Interference verification of injection molds on the web-based CAD viewer

As the interference between mold parts occurs in a small region, it is difficult to find the interference at the design stage. It is usually found at the assembly stage of injection molds, which delays both design and manufacturing leadtimes. Commercial CAD systems with interference inspection functions have been used so far. However, they are very expensive for the mold industry, and inadequate for performing collaborative work over the Internet. An interference examination system executable on a lower cost CAD viewer is required before releasing final drawings in the mold industry.
