The 12th China International Mould Technology and Equipment Exhibition in Shanghai, China, has come to a close. The conference can be said to be the largest in Asia and the second largest in the world. In this exhibition, it was learned that China's current total production of stamping parts processing mold has ranked third in the world, and began to gradually change from a mold importing country to a mold exporting country.
There are more than 30,000 mold production enterprises in the country, with about 1 million employees. In 2007, the company had sales of 87.0 billion yuan and exported 1.4 billion US dollars. The provinces and cities with the most exports were Guangdong, Zhejiang, Jiangsu, and Shanghai.
The mold industry has grown at an annual rate of 20% since 2000. During the “Eleventh Five-Year Plan†period, production and sales have been buoyant. The output, quality, and level have further increased, especially the development of the automobile manufacturing and IT manufacturing industries, which has driven the mold level. The improved and sophisticated mold manufacturing equipment provides guarantee for the improvement of mold technology level. According to Cao Yanan, executive vice chairman and secretary-general of the China Stamping Die Processing Industry Association, the Chinese mold industry is experiencing a “golden development phase†and will continue to grow rapidly over a period of time.
In recent years, the product structure of the mold industry has been accelerating. The development rate of high-tech molds represented by large-scale, sophisticated, complex, long-life molds is higher than the overall development speed of the industry, accounting for about 35% of the total molds. In 2007, the export volume of molds increased by 35.73%, the deficit further decreased, the structure of imported and exported molds became more rational, and domestic molds replaced imported molds have become a climate.
From the perspective of industry structure, the rapid development of private enterprises, the increased vitality of state-owned enterprises, the rapid increase in the number and ability of market-oriented professional mold manufacturers, stamping parts processing mold gathering production parks to adapt to the production characteristics of the mold industry development, the mold industry in the Midwest, etc. The developed regions have made great progress.
Some stamping parts processing mold enterprises have achieved multi-position progressive die precision of 2 micron, life expectancy of up to 300 million crush times, and individual enterprises' multi-position progressive die can be used in high-speed punching machines of 2500 beats per minute. Up to 1 micron. Has been able to produce large-screen 43-inch color TV, 65-inch rear-projection TV mold, 10 kg large-capacity washing machine full set of plastic mold and car bumper, the overall instrument panel and other large plastic mold.
Precision plastic stamping parts processing molds have been able to produce plastic parts for cameras and mobile phones, multi-cavity small module gear molds, and 7800 cavity plastic molds with precision up to 5 microns. Large precision complex die casting molds have been able to produce escalator integral pedal die casting molds, automobile rear axle gear box die casting molds, and casting molds for automotive engine housings.
The car cover mold has been able to produce a full set of outer cover molds for mid-range new cars. Radial tires for active dies, aluminum alloys and plastic door and window profile extrusion dies, precision casting or resin rapid prototyping draw dies have reached a very high level.
At present, on the whole, China can only say that it is a big country for stamping parts processing mold production and can not be said to be a strong country. There is still a 10 to 15 year gap between the products and the developed countries, and it is still dominated by middle and low grades. , China's mold industry will continue to grow rapidly in recent years, showing the following characteristics: products continue to be more large-scale, sophisticated, complex and rapid economic direction, the technological content will continue to increase, the manufacturing cycle continues to shorten, stamping parts processing mold production We will continue to develop in the direction of informatization, digitization, refinement, high speed, and automation. The company will further enhance its comprehensive strength and core competitiveness in all aspects.
Specifications
Intelligent leakage detection,
Close the valve according to leak flowrate,
timely detection less than 3 seconds.
Characteristic
For Gasoline, Kerosene, Diesel;
The leak detector will control the output of oil in time, when the oil leakage in the pipeline is no less than 11.4L/min;
The leak detector will delay to open in 2-3 seconds, when the oil leakage is less than 11.4L/min;
MLD2 Mechanical Leak Detector can keep maximum flow rate while several nozzles are working at the same time.
With
the growing consciousness of human environmental protection, relevant
environmental protection rules and regulations are made one by one
around the world. In order to observe the local environmental protection
rules and regulations, and to avoid pollution from oil leakage, the
leak detector is developed and put into use widely.
Under
the transmission pressure at 1.4-3.5KPa, diaphragm type of MLD
mechanical leak detector is a selectable device for submersible pump to
monitor the oil leakage in the pipeline. The leak detector can
automatically carry out the supervision to the flow rate over 11.4L/min
or pressure less than 0.6KPa of the pipeline. If leakage existing, it
will limit the flow rate at 11.4L/min through closing the inner piston
valve, which will let the users know that there is oil leakage in the
pipeline.
