Domestic mold companies are still in development, but many die in Europe and America the production technology, is already in the international class, the high technology used in mold design and manufacturing, rapid manufacturing of quality tooling has become a powerful guarantee.
First, the high-tech companies in Europe are widely used mold.
1, in Europe and America, CAD / CAE / CAM has become the universal application of die enterprise technology, CAD / CAE / CAM wide application, showing the use of information technology to stimulate and promote the superiority of the mold industry. According to the International Association for the Secretary-General Luo Baihui model introduction. In the application of CAD, has gone beyond the drawing board to get rid of two-dimensional drawing of the initial stage, the current 3D design has reached 70% ~ 89%. PRO / E, UG, CIMATRON and other software applications are common. These software applications can not only complete 2D design, 3D models also available for NC programming and CAD / CAM integration to provide a guarantee. Application of 3D design, but also in the design of the assembly interference checking to ensure the design and craftsmanship and reasonable. CNC machine tool widely used, ensure that the mold machining accuracy and quality. 30 to 50 people die companies, typically have a dozen sets of CNC machine tools. After CNC machining parts directly to assembly, so that greatly reduced the number of assembly fitter. CAE technology has gradually matured in Europe and America. In the application of CAE in injection mold design analysis software to simulate the plastic die process of the cooling process to predict the molding process defects may occur. Application of CAE in die design software, simulation of metal deformation process, the distribution of stress and strain analysis to predict rupture, wrinkling and springback and other defects. CAE technology in mold design and growing role in the Italian application of CAE technology COMAU company after the tryout time was reduced by 50%.
2, in order to shorten the molding cycle, improve market competitiveness, commonly used in high-speed machining technology. High-speed cutting is the cutting speed, high feed rate and high processing quality as the main feature of the processing technology, the processing efficiency of the cutting process than the traditional higher several times, even ten times. At present, European and American enterprises in the production molds are widely used high-speed CNC milling, multi-axis linkage comparison, there are some five-axis, the rotation is generally ~ 30 000 15 000 r / min. High-speed milling technology, can greatly shorten the molding time. The high-speed milling of the mold surface after finishing with only minor polishing can be used, save a lot of grinding, polishing time. Europe attaches great importance to technological progress mold companies and equipment updates. Equipment depreciation period is usually 4 to 5 years. Increase the speed CNC milling machine, a mold one of the key business investment in equipment.
3, rapid prototyping and rapid tooling technology universal application. As an increasingly competitive market, product upgrading is accelerating, rapid prototyping and rapid tooling technology came into being, and quick access to common applications. Exhibition in the European mold, rapid prototyping and rapid tooling technology occupies a very prominent position, with SLA, SLS, FDM and LOM and other types of rapid prototyping equipment, but also specializes in prototyping and manufacturing services to institutions and companies.
Die enterprises, many of the rapid prototyping and rapid tooling mold used together, namely the use of rapid prototyping technology to produce a prototype product components. And then quickly create a prototype based on the mold. Many manufacturers use of rapid prototype plastic mold pouring silicone rubber mold, plastic parts for the small amount of reproduction, is ideal for product trial.
Second, the mold business management experience in Europe and America should learn from.
1, the force reduction, "thin" type management. Most mold companies in Europe and America is small, number of employees over a hundred less, the number of mold companies are generally 20 to 50 people. Configuration of various categories of personnel is very streamlined, multi-skill, more than one post within the enterprise can not see the idlers. Lean production, "thin" type of management thinking has been well reflected.
2, the use of specialized, product positioning standards. Luo Baihui the mold inspection companies, mostly around the automobile and electronics industries, the demand for various types of mold to determine their product positioning and market positioning. In order to survive in market competition, and development, each manufacturer has its own advantages mold technology and products, and have adopted specialized methods of production. Most mold companies both in Europe and America a number of long-term cooperation in the mold user, a group of companies around the large mold mold manufacturer collaboration. This reciprocity, mutual benefit, win-win partnership coexist, and some have lasted 30 to 40 years.
3, the use of advanced management information system to achieve integrated management. Mold companies in Europe and America, especially in larger enterprises die, basically a computer management. From production planning, process development, to quality inspection, inventory, statistics, the widespread use of computers, various departments within the company to share information via computer networks.
4, the process management of advanced, high degree of standardization. Most of the domestic mold factory to adopt a fitter or fitter-based lump sum of different modes of production organization, is a mold manufacturer in Europe and America by the advanced process equipment and process routes to ensure part accuracy and production schedules. Deputy dies of each design are detailed, including the detailed design of each part, and have developed a detailed process.
Mold companies in Europe and America advanced technology and advanced management to the production of large, sophisticated, complex mold, to promote the automotive, electronics, telecommunications, home appliances and other industries play a vital role, but also to bring good die business economic benefits. U.S. mold companies, per capita annual sales of 20 million dollars; Italy, per capita sales are $ 100,000 or more. Compared with the domestic mold companies, even after deducting price factors, the production efficiency of European and American mold than we many times higher. Luobai Hui said, to narrow the gap with the advanced industrial countries, technological progress must be accelerated to improve the CAD / CAE / CAM application level, increasing the proportion of CNC machining equipment, the use of information technology to further improve the mold design and manufacturing standards. At the same time, to learn foreign advanced management experience, and further deepen the enterprise reform. At present, some mold factory dies, plastic molds are made, large, medium and small molds are done, so hard to do well, must take the small and specialized, small but excellent, small and special way. At the same time to enhance the awareness of international competition, strengthen international economic and technological cooperation and exchanges, in improving the degree of localization, while the mold to further expand exports to the world. |
