Plastic mold processing five links: 1, with product data management, data management technology and effective management of drawings and documents: for effective mold product data management, process data, drawings, comprehensive management, can ensure the consistency of documents, drawings version; this can achieve efficient sharing and efficient query utilization . A complete computer database of file management can be established to accumulate information about design drawings, dispersion, dispersion and isolation of organizational concentration. It is not easy to prevent problems caused by design, 2d, 3d, original settings, changes, maintenance version confusion, inconsistent data between 3D model and 2D drawings, 2D drawing design standards, and confusion. When found and corrected, resulting in mold modification and rework, or even ineffective, increase the cost of mold manufacturing, extend the mold manufacturing cycle, affect the problem. 2. Maintain consistency and integrity of plastic mold drawings, processing technology, physical data, and ensure consistency and integrity of mold drawings, processing technology and physical data through effective, meticulous and strict testing means. 3. The design and manufacture cost of each set of plastic mold must be summarized in time: effectively control the distribution of the work conveyor belt in the workshop, effectively manage the scrap of cutting tools; through the precise design of the mold structure and the precise inspection of the mold parts processing and parts, change the previous practice, will effectively reduce the extra cost of mold maintenance. The actual cost of each mould is obtained, and the quality of the mould is effectively controlled. 4. It is an organic combination of overall planning, planning, design, processing technology, workshop production situation and human resources information. It can effectively coordinate planning and production, effectively ensure the quality of plastic molds and timely delivery. 5. Establish a complete and practical plastic mold production management system, establish a complete set of mold production management system, realize product data management mold production management process, process data management, planning management, schedule management, computer information management system, including planning, mold design, plastic mold, production process, Workshop tasks and product inspection, warehouse management, mold making and related auxiliary information from planning to shipment to complete, can achieve a comprehensive tracking management.
