It is reported that high-tech companies in Europe are widely used mold, mold in many European and American companies in the international production technology is first class. will be used in mold design and high-tech manufacturing, rapid manufacturing of quality tooling has become a powerful guarantee.
A high-tech used in mold design and manufacturing
(A) CAD / CAE / CAM wide application, showing the use of information technology to stimulate and promote the superiority of the mold industry
In Europe and America, CAD / CAE / CAM has become the universal application of die enterprise technology. 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. Application of the software 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 ~ 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 growing role of design, the Italian company applied COMAU CAE technology, test mode time by 50% or more.
(B) 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 than the conventional cutting process to be several times higher, or even ten times. Currently, the 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 generally 1.5 million to 30 000 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.
(C) rapid prototyping and rapid tooling universal application
The 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,
plastic prototypes, 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 service agencies and companies.
In the mold inspection companies, many of the rapid prototyping and rapid tooling mold used in combination, 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
(A) of the force reduction, Most mold companies in Europe and America is small, number of employees over a hundred less,
communication products design, the number of inspection 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,
(B) use specialized, product positioning quasi
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,
product design development, and development, each manufacturer has its own advantages mold technology and products, and have adopted specialized methods of production. mold companies both in Europe and America most of the mold a group of long-term users, 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.
(C) 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.
(D) technology, advanced management, high degree of standardization
Most domestic and die factory taken to the main fitter or fitter contracted to 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. Vice die each have a detailed design, including the detailed design of each part, and have developed a detailed process. our mold to the world, is essential to deepen and expand exports.
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 mold enterprises good economic returns. 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 are many times higher. 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. Meanwhile, we should learn from foreign advanced management experience, to 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 enhancing the awareness of international competition, strengthen international economic and technological cooperation and exchanges, in improving the degree of localization of the same mold, and further expand exports to the world.
