Survey on the development of the Italian construction hardware industry
In China, the quality of construction hardware has always existed. No matter the building that broke out before, the building is upside down, or the building is innumerable. Although it is exposed every time, it still has not attracted the attention of the industry. In foreign countries, the level of production technology of Italian construction hardware companies is first-class in the world. The application of high technology to the design and manufacture of construction hardware has become a powerful guarantee for the rapid manufacture of high quality molds.

1. The extensive application of CAD/CAE/CAM shows the superiority of using information technology to drive and enhance the mold industry. According to Luo Baihui, in Italian hardware companies, CAD/CAE/CAM has become a universally applied technology. In the application of CAD, it has surpassed the initial stage of removing the drawing board and two-dimensional drawing. At present, the 3D design has reached 70% to 89%. Applications such as PRO/E, UG, and CIMATRON are common. The application of these software not only completes the 2D design, but also obtains the 3D model, which guarantees the integration of NC programming and CAD/CAM. With the 3D design, it is also possible to check the assembly interference during design to ensure the rationality of the design and process. The universal application of CNC machine tools ensures the machining accuracy and quality of mold parts. Hardware companies of 30 to 50 people generally have more than 10 CNC machine tools. Parts machined by CNC machine tools can be assembled directly, reducing the number of assembly fitters. CAE technology plays an increasingly important role in mold design. After applying CAE technology, Italian COMAU has reduced the test time by more than 50%.
2. In order to shorten the molding cycle and improve the market competitiveness, high-speed cutting technology is widely used. High-speed cutting is a processing technology characterized by high cutting speed, high feed rate and high processing quality. Its processing efficiency is several times or even ten times higher than the traditional cutting process. At present, Italian hardware companies widely use CNC high-speed milling in production, and there are many three-axis linkages, and some are five-axis linkage. The number of revolutions is generally between 15,000 and 30,000 r/min. High-speed milling technology can greatly reduce molding time. After high-speed milling, the mold surface can be used with only a little polishing, saving a lot of grinding and polishing time. Italian hardware companies attach great importance to technological advancement and equipment renewal. Equipment depreciation period is generally 4 to 5 years. The addition of CNC high-speed milling machines is one of the key points of equipment investment in hardware enterprises.
The Italian mold company has advanced technology and advanced management, which makes it produce large, precise and complex molds, which plays an extremely important role in promoting the development of automobiles, electronics, communication, home appliances and other industries, and also brings good products to mold companies.
