M2 Standard Edition of Mold Manufacturing Execution Management System

In the market competition of mold enterprises, the core elements of competition are the comprehensive competition of delivery, quality and cost, and behind the competition of these three factors is whether the enterprise has established an efficient management mechanism and management system.

MES-M2 is a mold manufacturing execution management system designed and developed by Dian Wei Company, which helps mold enterprises to establish an efficient and standardized information management system. The system mainly focuses on the management of mold manufacturing process, focusing on the pre-sale quotation and order management of mold; Basic norms and project management; Design and process management; Production scheduling and visual scheduling, dynamic monitoring of production process; Trial mould management; Procurement and inventory management; Eight main aspects, such as real-time monitoring and management of mold manufacturing cost, provide real-time dynamic information management and other functions. Through centralized coordination and management, the resources of Sharing Manufacturing can be integrated and the manufacturing process can be coordinated under the networked environment, so as to enhance the overall rapid response capability of mold manufacturing enterprises. So as to ensure the delivery, quality and cost of molds and help mold enterprises improve their profitability and competitiveness.

Although enterprise management has certain rules and patterns to follow, it is greatly influenced by enterprise scale, industry, national macro-policy and economic situation, product characteristics and manager style in the specific management process. We know that there is an old management motto: management is infinite. Therefore, we have always adhered to the company's core business model: standardized modules and customized development. Aiming at each customer, on the basis of in-depth investigation and excavation of the real needs of customers by professional senior consultants of the company, we discuss and study personalized and tailor-made enterprise management solutions to meet the actual needs of customers. Avoid adopting a one-size-fits-all management model in enterprise management, build a management system and platform that truly belongs to customers, and help customers improve management efficiency and competitiveness by establishing a management system suitable for enterprises themselves.

The functional modules of EMES-M2 standard edition of manufacturing information management system for mold enterprises include OA office management, sales management, project management, design management, procurement management, inventory management, production management, outsourcing management, quality management, equipment management, knowledge management and system authority and process setting management.

Function introduction of each module:

Sales management: mainly includes customer information management, quotation management, mold order management, accounting management and sales statistical analysis.

This module mainly carries out systematic information management on five main aspects of mold sales. Although the number of customers in mold enterprises is generally small, and sales are generally done by managers themselves. However, it is very important to systematically organize and manage the customer information and contact information of various departments. This not only helps to improve the communication and work efficiency between the staff of various departments and customers. At the same time, it is also to prevent the loss of sales staff from bringing unnecessary losses to the company and customers. Through the application of mold quotation management module, help mold enterprises accumulate and sort out quotation databases of different types of molds and provide them to customers. This can not only form the ability of the mold company to quote quickly and accurately, but also reduce the dependence and requirements on the personal factors of the quotation personnel. Through the statistical analysis of the specific contents of mold orders, accounts and sales, the purpose is to provide customers' contact information for all departments of the company and improve the mold progress and account collection. Strengthen the profitability and financial management ability of mold enterprises.

The specific functions of sales management are as follows:

Sales management:

1. Customer basic information management, contact information management of all departments;

2. The system provides the company with the function of quoting mould according to its own template, and the company can quote quickly and pertinently.

Different customers use different molds to make quotations, and you can refer to the company's quotation database.

Real model quotation information of related products. In order to form an accurate and true quotation.

3. Mold order management: the order content is systematically managed.

4. Account management: account registration and mold order management.

5. Statistics and analysis of mold sales.

6. Order permission settings. Through the setting of authority, the function of viewing the contents of the order by people unrelated to this project is effectively controlled, and the rigor of the order information is effectively controlled.

Design management: the design module mainly includes: mold design task allocation and progress monitoring management; Die BOM and drawing upload approval, drawing version control and collaborative design, collaborative browsing and marking of drawings, collaborative design and online client audit, processing technology database management, design change management and process and electrode management of processed parts.

The design ability of the design department of mold enterprises is very important, but the management of the design department is more important. Under the existing design ability, the effective management of the design department can not only shorten the design cycle of the mold, but also avoid the waste caused by purchasing mistakes through strict audit of the BOM. Through collaborative online browsing, marking, measuring and other functions, not only can the design exchange and review with customers and internal personnel be realized quickly, but also the online browsing and inquiry of drawings by personnel in design, procurement, technology and processing departments can be realized, saving paper for printing drawings. Through effective version control of drawings, processing errors caused by different versions of drawings used by design and processing departments can be avoided. Through part process management, the company's process management database can be effectively formed and processing experience can be accumulated. Therefore, effective management of the design of mold company can not only help enterprises to manage the design through standardization, but also accumulate design and process experience and improve design ability and efficiency.

Specific functions of design task management:

1) designer's load query and design task assignment;

2) Designers' design progress submission and progress monitoring;

Procurement management: the procurement management module includes: supplier and contact information management, procurement classification and purchase application, procurement inquiry and purchase order formulation and approval, purchase order management and arrival management, purchase account and bill management and other functions.

Most of the material procurement of mold enterprises is order-based procurement, which is generally based on the BOM list after mold design. Therefore, the mold procurement has a large workload, tight time, many kinds of materials and a wide range of material specifications. If the efficiency of mold procurement can be improved, once the mold design is completed, submit the BOM, and if the order can be placed quickly, it is equivalent to reducing the procurement cycle and shortening the mold manufacturing cycle. Therefore, through the procurement management module, we can quickly determine the types and specifications of materials according to the mold design, check the warehouse in time through the information system, quickly compare the purchase price, make inquiries from suppliers in time, and quickly form purchase orders through online approval. After the arrival and warehousing registration of purchased materials, the personnel of the production department can check the arrival information in time through the system and organize production quickly. Therefore, effective procurement management can not only shorten the procurement cycle, but also improve procurement efficiency and capital utilization. It can also reduce the repetitive workload of procurement personnel, make procurement personnel free up more time to find more high-quality suppliers, and lay a good foundation for the company to reduce procurement costs.

The specific functions of this module are as follows:

1). Supplier information: basic information of suppliers, classification and records of available materials.

2). Contact information: contact information of the supplier.

Inventory management:

The main functions of inventory management: mold material information and code setting, warehouse category, material purchase application, material warehousing, material arrival confirmation, monthly material inventory and statistical analysis.

Generally, there are many kinds of materials in stock in mold enterprises, and the quantity is relatively small. The difficulty of manual management is that there are many specifications of raw materials, especially the remaining materials are not easy to find, which often leads to the long-term storage of purchased invalid materials and is not easy to be used. Secondly, there are many kinds and quantities of tools. Frequent repeated borrowing and the time and times of scrapping are difficult to manage, which often leads to great waste. For injection molds, there are a large number of electrodes of various specifications, which are in great stock, but it is a pity to scrap them, and it is not easy to find and manage after reuse. If we can effectively manage the above difficulties by designing corresponding functions, it will save a lot of material costs for mold enterprises, reduce capital occupation and directly reduce the material costs of molds.

production control

At present, the mold company has a large number of orders, and the personnel and equipment resources are double tight. Coupled with the characteristics of single piece and small batch mold production, most production managers mainly make mold production plans in a short time based on their own management experience, combined with limited equipment resources and actual production conditions. At present, this planning mode is difficult to play a real guiding role in the actual production process of molds. The production workshop often makes repeated production and processing plans, which leads to the inconsistency between the plan and the reality in the mold production process, and the production management problem is more prominent, which has become one of the management difficulties of many mold enterprises. Because it is difficult for the mold production planner to accurately grasp the resource load of personnel and equipment, and it is also difficult to grasp the resource demand of all the molds in process and molds to be processed in a short time, the plan made is full of personal experience and blindness, and there is only a production notice. Therefore, it is difficult to really carry out production according to this plan or play a guiding role in the workshop. This also leads to the uncontrollable progress of mold production and processing, and the deviation between the plan and the actual situation is great. It also leads to the continuous change of processing tasks, but the production and processing are often in a disorderly state, and the processing quality and delivery time are difficult to guarantee. In actual management, it is difficult to carry out and assess as planned. Therefore, people in the production department often work overtime, often work as firefighters, and constantly "put out the fire", which still cannot fundamentally solve these problems, and this has always been one of the outstanding management problems of many mold companies.

The root cause of these problems is that mold enterprises are mostly based on the traditional management mode, and they can't control the real situation of resource demand and resource load quickly and effectively when making production plans, and can't schedule quickly through a lot of scientific and effective calculations, so they can't make detailed production plans accurately at the planning level. So it is difficult to carry out execution and control at the level of execution and control. After deeply studying the root of the problem, Dian Wei Company developed a computer automatic production scheduling and scheduling management system for mold production planning, which specifically solved the management problems in mold production. Through the scheduling system, the personnel of the production planning department can conveniently and quickly meet the needs of mold production planning and daily production planning scheduling; Through a large number of rapid calculations in the computer scheduling system, equipment resources, materials, human resources and other factors, such as working hours of processing technology and delivery date of molds, can be quickly and organically combined to form an effective scheduling processing task and external processing task list. At the same time, early warning will be given to the delayed molds and keys before processing, so that the company can arrange outsourcing in advance or inform the sales staff to communicate with customers in advance and extend the delivery time of molds. The factors leading to the delay were solved before the production of each mold, which not only effectively guaranteed the delivery date, but also made the production and processing in a virtuous circle through systematic and scientific input scheduling, which not only improved the processing quality, but also greatly reduced the continuous temporary emergency outsourcing and the occurrence of mold delay. At the same time, during the implementation of the plan, the processing progress of parts can be submitted quickly and effectively through the application of wireless collectors, and the system can display the processing progress and status of each mold and workpiece at any time, so that production personnel can monitor the actual processing progress of molds and workpieces at any time. In the process of production and processing, even if there are concessions, rework, scrap and other unqualified situations. When collecting data, the inspector will make a preliminary judgment, transfer these workpieces to the processing exception list for processing, and the production management personnel (after discussing with the quality technicians) will finally confirm the processing results of the workpieces. For those who give in, the flow process will continue, for those who need to rework, a rework process needs to be written, and for those who are scrapped, tasks to be purchased and tasks to be processed will be automatically generated after confirmation. Even if there is an abnormality, the alarm will be immediately fed back through the system, which also improves the speed of timely handling and makes many problems such as mold delay be dealt with in time. Thereby effectively improving the delivery time of the mould.

The specific functions of mold production management are as follows:

1) production plan: receiving operation instructions and making production operation plans.

2) Work instruction: Work instruction for mold production project.

3) Manufacturing list: list of molds and their workpieces that need to be produced or processed;

4) Scheduling: scheduling processing tasks, and arranging processing on certain equipment within a certain period of time;

5) Task distribution: print and distribute the scheduling results and production process cards.

6) Production monitoring: workshop production plan monitoring and progress submission resource Gantt chart: view equipment resource status and tasks.

13) drawing file retrieval: search the drawing file of the machined workpiece in the current version.

Outsourcing management: it mainly manages the fixed outsourcing, planned outsourcing and temporary outsourcing tasks generated in the mold production process, such as outsourcing arrangement and tracking, outsourcing inspection and payment.

In mold production, the outsourcing amount is generally large. The main reason is that some mold processing equipment, such as material conditioning, can't be purchased or invested by mold companies, and some of them can't be completed on time due to insufficient resources of their own processing equipment. Whatever the reason, the effective management of outsourced parts processing can help mold enterprises turn other processing equipment into their own processing workshops or factories in different places, so that mold enterprises can increase more production capacity, accept more orders with better quality and create more profits without increasing investment. At the same time, many unnecessary outsourcing costs can be reduced by effectively making an orderly external processing plan. The outsourcing management of this system mainly divides the external processing parts of the mold company into three parts according to the reasons and time sequence: fixed outsourcing, planned outsourcing and temporary outsourcing, and manages these three parts in an orderly manner, and carries out complete and detailed management from the processes of mold outsourcing submission, outsourcing order, responsible person, outsourcing picking, inspection and payment. Ensure the delivery date and processing quality of mold outsourcing parts, and reduce unnecessary external processing. Good and orderly outsourcing management of mold enterprises can promote the better and faster development of mold enterprises.

The specific functions of outsourcing management are as follows:

1) foreign negotiation management: foreign negotiation classification, foreign cooperation and basic information management.

2) Contact information: contact information for foreign negotiations.

3) Processable items: define the processing types of outsourcing jobs that can be contracted for each outsourcing negotiation.

4) Outsourcing tasks: summarize and collect the outsourcing tasks needed in production to form outsourcing documents.

5) Subcontracting Doc: manage subcontracting Doc.

6) Outsourcing tracking: tracking and monitoring the implementation of outsourcing orders.

7) Payment registration: registration of outsourcing payment records.

8) Subcontracting reconciliation: at the end of the month, check the subcontracting records and expenses of various subcontracting negotiations in this period.

Quality management:

The particularity of mold production leads to the extremely complicated quality management of mold parts in the processing process. Because most die workpieces are only processed into one piece and their shapes are complex, they cannot be processed by conventional inspection methods. Only through a specific fixture or three-coordinate detection. It is also unrealistic to inspect all the workpieces on this basis. Therefore, in the production process of mold parts, the actual quality management can only ensure the processing quality of most parts through the design accuracy requirements and the accuracy of processing equipment. Three coordinates can only detect a few key workpieces. Finally, after assembly, the products are produced by trial mold, and the quality of the mold is tested by product quality. Therefore, the key to test the quality of the mold lies in the trial stage. Therefore, by strengthening the quality management in the mold trial stage, the purpose of strengthening the mold quality management can be achieved. In addition, through the effective management of mold trial, the number and cost of mold trial can be effectively reduced. Thereby reducing the manufacturing cost of the mold. Therefore, the quality management of molds in the system focuses on strengthening the quality management in the process of mold trial, the management of mold trial expenses and the management of abnormal problems in processing.

The specific function setting is to track and count the quality and cost of mold trial through daily inspection and abnormal problem feedback, and monitor the actual quality cost of mold trial anytime and anywhere. So as to reduce the cost of mold manufacturing and mold trial and achieve the purpose of mold quality management.

Main contents of quality management module:

1). Inspection records: inspection records such as outsourcing inspection, production process inspection and outsourcing inspection.

2) Test management: test application and test record management.

3) Application for mold trial: application and approval for mold trial.

4) Test records: records of test expenses and test results.

8) Maintenance record: equipment regular maintenance record.

9) Spare parts replacement: important spare parts replacement records of equipment.

Project management and cost management;

Mold enterprise is a production mode of single piece and small batch research and development, so the characteristics of project system are particularly obvious. The project management module of this system provides standard templates and monitoring templates for mold project management, and enterprises can set them for different mold manufacturing. You can assign a responsible person to each key link in the mold manufacturing process, make a plan, and the system will automatically notify the responsible person, and submit and monitor the actual implementation progress of each key link plan. Compared with the planned progress, the system can remind and delay the alarm, so as to achieve the purpose of monitoring the state of each key link of a mold. At the same time, the function of inputting or importing design BOM is provided, and the process and working hours of each self-made part can be formulated. By collecting the progress and process of processing parts, the purpose of effectively monitoring the processing progress of key parts of the mold is realized. Therefore, through project management, mold managers can achieve all the goals in the mold management process.

Through the project management function of the system, enterprises can conveniently set up control points for project and mold tracking according to actual needs, realize timely and dynamic tracking control of key control points such as project and mold manufacturing, quality and cost, and realize timely monitoring and management from macro to micro. At the same time, due to the B/S architecture design of the system, users can remotely log in to the company management system to monitor the progress of the project, thus reducing the labor costs such as the time and travel expenses of customers, thus providing value-added services to customers.

In addition, in the project management, we also effectively manage and statistically analyze the actual cost of molds:

Mold manufacturing links are diverse and complicated. Under the existing financial system, it is difficult to accurately and timely count the dynamic actual processing cost of each link in the actual processing of a mold. Even if it can be counted in time, it is after the mold manufacturing is completed. Most of the cost of molds occurs in the manufacturing process. In order to effectively manage the mold manufacturing cost, it is necessary to effectively control the dynamic cost in the mold manufacturing process. The mold cost management designed in this system is not bound by the previous cost management based on financial structure. Starting with the project quotation, the plan is made to control the cost, and it is decomposed into all aspects of mold manufacturing for monitoring. Through the system, the actual cost of the mold in the corresponding manufacturing link is collected in time, and compared with the planned cost, and the cost early warning function is carried out at any time when the planned cost exceeds or approaches this stage. Through this method, the die cost can be controlled in real time and dynamically in all aspects. The cost of a pair of molds occurs in this process. Only by dynamically controlling and comparing the cost elements of each link in time can we control the mold cost in time, ensure the profit of each mold and ensure the profitability of the company.
