China's mold machine tool equipment technology needs to be improved

China's mold machine tool equipment technology needs to be improved China's machine tool industry has been able to provide relatively complete set of high-precision processing equipment, but compared with some of the advanced equipment abroad, there is still a large gap.

Although many domestic companies have introduced many advanced foreign equipment, the overall level of equipment is much lower than many foreign companies. For a long time, the company has been affected by large and complete, small and total impact, the professional level of the domestic mold industry is relatively low, the professional division of labor is not detailed, and the degree of commercialization is also relatively low.

In the domestic annual production of molds, commodity molds only account for about 40% of the total, and the rest are for self-produced and used. The International Model Association Secretary-General Luo Baihui pointed out that the cooperation among mold companies is not smooth and it is difficult to complete large-scale mold sets of tasks. . At present, the level of standardization in the domestic mold industry needs to be improved. The low coverage of the use of standard mold parts also has a great impact on the quality and cost of domestic molds, especially on the mold manufacturing cycle.

On January 17th, the strategic alliance for mold industry technology innovation was established in Dongguan. Minister Ou Hailong from the Hardware Mould Province of Guangdong Province believed that the basic pattern of mold technology and standard system at home and abroad has been formed, and the standardization work of the mold industry has yet to be improved, relying on the country. The precision mold quality inspection center has established a mold standard system that meets the needs and development of China's mold industry, which is conducive to improving the application coverage rate of China's mold standard parts and the market competitiveness of the mold industry, and is active in promoting the continuous development and technological progress of the mold industry. significance. The Vice President Zhu Jianguo of the guests who spoke at Ningxing Die Steel, the director of Chen Deqiang of the mold base, and the general manager of Zhuo Minmin of the Fleck hot runner said that despite the long-term task of standardization, they are willing to contribute to the development of the industry and promote the innovation of China's mold industry technology.

Ningxing Vice President Zhu Jianguo said that as the largest mold steel manufacturer in China, Ningxing has annual production and sales of 1.5 billion mold steels, including sales of 400 million yuan in Guangdong Province. Currently, we have set up an information-based and standardized trading company and set up my steel network. We will follow the alliance to integrate resources and set up a one-stop shopping platform. We hope to make a difference. At present, China is investing in research to standardize hardware molds and templates. The ultimate goal is to automate and standardize the mold industry as soon as possible.

Minister Ou Hailong stated that the die standard system uses the eight major types of die as the standard subject of the die, including terminology, technical conditions, formwork, die parts, structural forms, experimental methods, technical acceptance conditions, safety, and other conditions. The standardization work is based on national standards, industry standards, and enterprise standards. A key part of the standardization work is to establish a standardization basis. The realization of corporate database construction and standard process construction will be standard work. The guarantee.

Boiler Air Preheaters


Energy Saving Air PreheaterAir preheater is one of the most important accessories in modern boilers. Air preheater is commonly found in all modern boilers. To increase the efficiency of the boiler accessories like air preheater is used in the boilers.

Types of air preheater in a boiler

The air preheaters are classified into two types based on their features and construction. These two types of air preheater are

Recuperative or Tubular type air preheater

Regenerative or Rotational type air preheater

Recuperative or Tubular type air preheater is further classified into two types, they are

Horizontal tubular type

Vertical tubular type

Regenerative or Rotational type air preheater is also classified into two types they are

Rotating baskets (Ljungstrom)

Rotating hood (Rothemuhle)
