The practical management method of mould

[Abstract] the competition among enterprises is becoming increasingly fierce. Improving the competitiveness of enterprises and improving the management has become the top priority of every enterprise. Because the mould determines the product quality and affects the production schedule, the management of mould will be paid more and more attention by enterprises and will become the focus of improving the enterprise management. Guanli's mold management system is a high-quality improvement management scheme developed under the guidance and support of the Hong Kong Machinery and Metal Industry Federation (FMM) and the Hong Kong Productivity Council (HKPC). In order to help many enterprises in the Pearl River Delta improve their mold management level, it has been actively promoted since 2006, including Chow Tai Fook Group, Tyco Electronics Co., Ltd Jiali Products Co., Ltd. and many other well-known enterprises have adopted Guanli MMS mold management system to improve mold management

analysis of the current situation of mold management

after the mold management system of Guanli was introduced to the market at the end of 2005, in one year of practice, Guanli has successively contacted nearly 1000 hardware, plastic and mold enterprises in the Pearl River Delta. It is concluded that only about 5% of the enterprises use the system to manage the development, use and maintenance of molds, while most of the other enterprises use Excel tables or access databases to do some simple procedures for management, These management methods basically use the file sharing method to share the collected data to users, which often has the following defects:

1, data integrity and logic are not strong

2. Insufficient data security and inconvenient control

3. The timeliness and flexibility of data statistical analysis are not enough;

4. There is no automatic reminder function

standard manufacturing progress flow chart

Guanli adheres to the principle that simplicity is efficiency, and standardizes the progress process into three steps: 1. Production plan; 2. Data collection; 3. Data analysis. See figure-1. ① production plan: the mold production sheet contains detailed production plan data, such as work order number, production mold number, workpiece and process arrangement; ② Data collection: the mold production sheet is issued to the tooling department, and the operators of each group (mold design group → numerical control group → modules → test modules, etc.) carry out construction according to the sheet, and then input the manufacturing progress data into the system in time through the production progress sheet; ③ Data analysis: the cost analysis and the analysis report of the actual manufacturing cost and progress can easily help managers realize the requirements from rough to fine management

key to progress tracking

progress tracking mainly hopes to improve production control management. While making full and rational use of production resources, it is necessary to control production progress as much as possible, complete production objectives on time, prevent abnormal conditions, find and solve abnormal conditions and problems in advance

although a large number of standard parts are used in mold manufacturing, in addition to standard parts, a set of molds generally consists of more than ten or more workpieces. In the production work order, each workpiece will have a clear process flow, processing unit, estimated working hours, start time and completion time. In total, the process of each set of molds may reach more than 100 items, Usually we just know the approximate progress of each artifact. In fact, if the manager wants to know the progress of each process of each workpiece, it will increase the heavy workload. More importantly, it is not an ideal method to only understand the progress of a single workpiece and evaluate whether the set of molds can be completed on time as a whole; Therefore, the key to progress control is to understand the overall impact of the actual progress of each workpiece on the mold. Guanli technology fully analyzes the number of workpieces, the estimated working hours, and the data of workpieces actually completed by ECD to predict the overall progress, and clearly and concisely let the manager know whether the mold can be completed on schedule through simple and easy to understand data and charts. See figure -2

actual man hour analysis

6. Important equipment of product machinery:

man hour analysis is the best data for managers to comprehensively evaluate work conditions, but the convenience and quickness of obtaining these data often affect our decision-making. However, to realize this kind of information management, it is obvious that the traditional manual records or excel statistics can not meet our management requirements, Therefore, many enterprises only do simple and single man hour analysis, or even do not do similar man hour analysis. Without the support of data, managers often can only use on-site feelings to evaluate employees' performance, which is difficult to achieve comprehensive, fair and reasonable evaluation. Such a result will lead to psychological imbalance of employees, easy to produce adverse psychology, and often backfire. For this reason, Guanli mold management system provides a comprehensive and combined way to examine the working conditions from the perspectives of mold number, processing unit, time segment, processing type (mold opening, mold repair, mold modification), payment type (self payment, customer payment), etc., so as to help enterprises easily and timely summarize and evaluate the working conditions and master the manufacturing progress at any time

detailed analysis of mold cost

Guanli believes that mold cost basically has two characteristics: first, cost sustainability and second, uncertainty of the cost payer. ① Cost Sustainability: after the mold is made, most of the molds will be used. 2. The electronic universal series will change and repair the mold, and these costs will continue to accumulate on this set of molds without transfer; ② Uncertainty of the cost payer: with the accumulation of the number of processed products, the payer of the mold repair costs will also change. For example, the cost of opening a new mold is borne by the customer, but the cost of internal mold repair for 50000 beer is borne by the enterprise, and then transferred to the customer. Therefore, the cost of the mold is not only the statistics of the processing cost and material cost, but also needs to be allocated to the payer of the cost when the great development period of fine composite aviation materials comes. The classification of the cost (mold opening, mold repair and mold modification) can more clearly reflect the distribution of the mold cost, Give the customer a clear account with the enterprise, so that the customer can rest assured to maintain a long-term cooperative relationship with the enterprise. For this, Guanli's mold management system provides a good solution, which enables the user to conveniently count the mold cost in terms of mold number, processing type (mold opening, mold repair, mold modification) and payment type (self payment, customer payment) and in terms of manufacturing fee, OEM fee, material fee and other details, It can also list the occurrence details of manufacturing cost and material cost in detail, which makes the tedious work of mold cost calculation fast and simple, and easily improve work efficiency

mold usage history management

mold is an important enterprise property in an enterprise. The management level of mold directly affects the quality of products and the delivery date of products, but its management is often neglected in an enterprise. Therefore, the concept of Guanli technology is to make enterprises pay attention to the management of mold usage history, promote the informatization management scheme of mold management, and establish a standardized mold delivery and receipt process for enterprises, Make regular and fixed maintenance plan, maintenance record analysis and management, mold life, etc. for the mold, so as to effectively search the data, track the mold history, understand the mold status, and achieve the purpose of intelligent operation.
