Southern heavy rain tests construction hardware, Italian hardware becomes the best choice

In the recent heavy rains and floods in purgatory in southern my country, if the quality of the building fails to pass, huge losses may be caused. In China, the quality of building hardware has always existed. Whether the building has been crooked, collapsed, or collapsed, there are countless Although it is often exposed, it still has not attracted the attention of the industry.

In foreign countries, the production technology level of Italian construction hardware companies is first-class in the world. The application of high technology to the design and manufacture of architectural hardware has become a powerful guarantee for the rapid manufacture of high-quality molds.

1. The wide application of CAD/CAE/CAM shows the superiority of using information technology to drive and enhance the mold industry. According to Luo Baihui's understanding, CAD/CAE/CAM has become a commonly used technology in Italian hardware companies. In the application of CAD, it has surpassed the initial stage of getting rid of the drawing board and two-dimensional drawing. The current 3D design has reached 70% to 89%. The application of software such as PRO/E, UG, CIMATRON is very common. The application of these softwares can not only complete 2D design, but also obtain 3D models, which guarantees the integration of NC programming and CAD/CAM. With 3D design, assembly interference can also be checked during design to ensure the rationality of the design and process. The universal application of CNC machine tools guarantees the machining accuracy and quality of mold parts. Hardware companies with 30-50 employees generally have more than ten CNC machine tools. Parts processed by CNC machine tools can be directly assembled, which greatly reduces the number of assembly fitters. CAE technology is playing an increasingly important role in mold design. After the application of CAE technology by Italian COMAU, the mold trial time has been reduced by more than 50%.

2. In order to shorten the molding cycle and improve market competitiveness, high-speed cutting technology is generally used. High-speed cutting is a processing technology with high cutting speed, high feed rate and high processing quality as its main features. Its processing efficiency is several times higher than traditional cutting technology, or even ten times. At present, Italian hardware companies widely use CNC high-speed milling in their production. There are more three-axis linkages, and some of them are five-axis linkages, and the number of revolutions is generally 15,000 to 30,000 r/min. The use of high-speed milling technology can greatly shorten the molding time. The mold surface after high-speed milling and finishing can be used with only a little polishing, which saves a lot of time for grinding and polishing. Italian hardware companies attach great importance to technological progress and equipment renewal. The depreciation period of equipment is generally 4 to 5 years. The addition of CNC high-speed milling machines is one of the key points of equipment investment for hardware enterprises.

Italian mold companies have advanced technology and advanced management, so that the large, precise and complex molds they produce have played an extremely important role in promoting the development of automotive, electronics, communications, home appliances and other industries, and also brought mold companies to It has a good economic benefit.
