In the past two years, the sales of many mechanical equipment in the mold industry have been declining, but the testing instruments such as 2.5-dimensional and three-coordinate detectors are constantly growing. It can be seen that the improvement of quality is the necessary reform of the current plastic mold manufacturers. direction. But is the quality of the plastic mold made or detected? After years of exploration and continuous learning, Shenzhen Hongkaiyun Technology has come to a conclusion: to ensure the quality of the mold, the quality control in the processing and manufacturing of plastic mold is the key link of the quality of mold manufacturing. Specifically, we can start from the following aspects:

1) Effective management of product data management, process data management, and drawing document management: effective product data management, process data management, drawing document management, ensuring the comprehensiveness of documents, consistency of drawing versions; enabling drawings Achieve effective sharing and effective query utilization. A complete file management computer database can be established, and the design drawings accumulated by the design department, scattered, and previously scattered and isolated information can be collected and used to prevent 2d, 3d confusion, original, set, and maintenance versions due to design drawings. Confusion, 3d model and 2d drawing data inconsistency, 2d drawing design is not standardized, chaotic and cause problems are not easy to be discovered and corrected in time, resulting in mold modification and rework, or even invalid, increase mold manufacturing costs, lengthen mold manufacturing Production cycle, affecting delivery.

2) The design and manufacturing cost of each set of molds must be summed up in time: Effectively control the scrapping of the work orders through the workshop, effectively manage the scrapping of the tools; through accurate mold structure design, efficient mold part processing and accurate zero The detection of accessories will effectively reduce the additional cost of the mold due to the change and maintenance, so as to obtain the actual cost of each set of molds and effectively control the quality of the mold.

3) Maintain the consistency and integrity of the mold drawing, processing technology, and physical data: ensure the consistency and integrity of the mold drawing, processing technology, and physical data through effective, meticulous, and rigorous testing methods.

4) Overall planning: organically organize and integrate the information of planning, design, processing technology, workshop production, human resources, etc. to coordinate and plan, and effectively coordinate the planning and production, which can effectively guarantee the quality of the mold and deliver on time.

5) Develop a complete and practical mold production management system: develop a complete mold production management system, realize the product information management, process data management, plan management, schedule management computer information management system of mold production management process, Including mold production planning, mold design, process development, shop task assignment and product inspection, warehouse management, etc., so that mold manufacturing and related auxiliary information from the planning to completion of delivery can achieve comprehensive tracking management.

6) Establish processing technology: establish processing technology, summarize mold parts list, purchased parts list, standard parts list, self-made parts list, self-made standard parts list, material list, heat treatment parts list, vulnerability The list and mold costs ensure that relevant resources are in place. Combine production planning management and schedule management to ensure that relevant equipment can be effectively used, prevent personnel from being idle, and make all links in processing and manufacturing interlocking.

7) Establish a quality inspection department, strictly standardize the testing methods, eliminate the “almost” luck, and ensure the precision of each part of the mold processing. Effectively control mold quality and effectively correlate quality to individuals based on upper and lower process records. It can enhance the design and the responsibility of the operator.

8) According to the company and the customer's situation, develop mold design standards and mold design work instructions for the company and customers; mold manufacturing standards, mold manufacturing operation instructions, standard mold design and mold manufacturing; prevention because of personal Habit, the old mold-making thinking creates molds that do not meet customer requirements.

9) Establish a mold project follow-up management team: set up a communication and supervision bridge between the customer-market-engineering-procurement-manufacturing-warehouse-injection and other departments, conduct detailed business and technical communication, and fully understand the customer's details. Mold technical requirements, record and summarize the content of communication and accurately communicate to the ministries, avoiding repeated, multiple, trial, modification, rework, thus saving costs and time. A customer knowledge and technical knowledge base is gradually established for each customer and shared within the company to improve customer service and reduce errors. Follow up and supervise the production progress of the mold project, arrange the test mode, follow up the relevant materials, confirm the sample test, send samples, arrange the mold and so on.

Plastic mold manufacturing, as the mother of industry, stands on the cusp of the opportunity and challenges. Only self-training, eliminating old equipment and investing in precision equipment, and introducing advanced management mechanisms to strictly control the processing and manufacturing links can effectively improve the mold. quality.
