In the production process, the mold will be subject to normal wear. To be sure, quality management control in daily production will play an important role in mold quality assurance, mainly including the following aspects: 1. Effective data management Including production data, process data and drawing documents: effective management of production data, process data and 2D / 3D drawing documents can ensure complete document library and complete drawing version, so as to realize effective sharing and effective query. Drawing. In the engineering department, if a database with a complete document management system cannot be established, and no one collects and organizes previously scattered drawings, data will be confused and inconsistent, which may affect all design documents, including 2D / 3D drawings. 2. Original data, design change / maintenance history, 3D model, etc. If there is no standardized 2D CAD drawing, there will be a lot of problems. Because of this confusion in...
