To ensure the cost of the Pet Bottle Mould, the cost control is directly proportional to the relationship between quality and delivery. The quality of the mold should be one-time, less modified, and the delivery should be shortened, so that the manufacturing cost is low, the profit is high, and the market order is in the process of undertaking. Only have a unique competitive advantage. On the contrary, companies not only have no advantage, they also do not make money or even lose money. Therefore, mold manufacturing costs and production management are very important in the control part, from the following aspects:1) Effective management of product data management, process data management, drawings, document management: effective management of product data, process data management, drawing document management, can ensure the consistency of comprehensive documents and drawing versions; effective sharing and effective query utilization .2) Maintain consistency and integrity of mold drawings, processing techniques and physical data: Ensure consistent and complete mold drawings, processing techniques and physical data through effective, detailed and rigorous testing methods.3) Each mold design and manufacturing cost must be completed in time: effective control of tool scrapping by effective control of shop part processing technology download or shared printing; effective mold structure design, efficient mold part processing and accurate part inspection will be effective Reduce the replacement, maintenance and additional costs of the mold set, thereby obtaining the actual cost of each set of molds, and planning the cost in real time to effectively control the quality of the mold.4) Master plan: organically organize the project planning, design, processing technology, workshop production, equipment, human resources and other information, integrate them, coordinate planning and production, and effectively guarantee the quality of the mold and pay on schedule.5) Develop a complete and practical mold production management system: mold production management process to achieve product data management, process data management, project management, schedule management computer information management system, including mold production planning, mold design, process production scheduling, parts Real-time bar code submission, product inspection, warehouse management, mold manufacturing and related auxiliary information for progress from real-time tracking management from planning and manufacturing process control to delivery completion.6) Formulation of processing technology: formulate processing technology, summarize mold parts list, purchased parts list, standard parts list, self-made standard parts list, material list, heat treatment list, vulnerable parts list and mold cost to ensure timely and relevant resources are in place. Combined with production planning management and schedule management, it ensures that the relevant equipment can be effectively used to prevent employees from being idle, thus enabling all aspects of processing and manufacturing to be interlocked.7) Formation and implementation of quality culture: Analyze the self-inspection, special inspection, inspection and inspection processes of various departments of the enterprise, and summarize the formation of quality standards. Strictly standardize testing methods to eliminate the "almost" luck and ensure precision mold processing parts. Effectively control the quality of the mold and effectively link the quality of the individual to the individual according to the next process record. Can enhance the design, the operator's sense of responsibility.8) According to the development of the company and customers, the company and customers on the mold design standards, mold design work instructions, mold manufacturing standards, mold manufacturing work instructions, mold design and mold manufacturing specifications; customary, the old thinking of making molds does not meet the customer's Claim.9) Standardize procurement, warehouse and production orders, material delivery, tool loss reporting, delivery management, rationalize the material supply chain, and prevent production lines.10) Establish a comprehensive evaluation system: Accurate, original, and true data correctly evaluate each employee, regularly train mold design, mold manufacturing personnel, and find and train the backbone of the elite team of china pet preform manufacturers.
