September.30.2010 The industry insiders said that in the industrial process the valves are most used to control the flow and flux of various liquids such as water, oils, chemicals, etc., according to parameters of temperature, pressure and flow. The general-used control valves in factories are pressure reducing valve, pneumatic fixed temperature valve, solenoid valve fixed temperature system, constant temperature control valve proportional system, temperature control valves and other types. In the selection of various types of automatic valves, in order to achieve economic and practical purposes some blow molding machine factors should be considered including the type of heat engine, the required accuracy, the quality of control valve, pressure drop, flow and structure, the failure rate, valvemanufacturers credit and after-sales service. As for the plastic valve, it’s a cost-effective choice for practitioner because of its advantages of easy-fitted, low failure rate and the accordance with the industrial hose automation needs. Because the conventional pneumatic valve and bag making machinemust matched with pipes, solenoid valve and compressor, while the electric valve is driven by motor, easy to pvc fitting install, and can be installed with the original robotic factory line, which could save other slitting machine costs. In addition, the opening and closing can be smooth-going by the pipe fitting motor-driven way without the shortcoming of immediate excessive momentum, so the failure rate can be substantially reduced. Many people think that the cost of using electric valve is high, on the contrary, if calculated from the holistic basis, the traditional valves should plus the cip installation cost of many accessories and pipelines, therefore the price is not dominant but even undertaking more maintenance costs.

September.24.2010 The recovery of China machinery industry will evolve from downstream special equipment to machine parts, then to machine tools and other general equipments, which is a gradual process. Now the demand still mainly comes from domestic, such as railway, highway, subway and other items, if the private investment and exports recover in the second half year, the construction machinery industry will still be the most beneficial industry, but the recovery of machine tools and other general slitting machine, shipping industry are lagging behind. As the raw material price is increasing continuously and the power is not enough, it is expected that the profit of machinery industry will be improved in the second half year. At present, the packing machine industry is undergoing a gentle revival. Because the capacity utilization rate was insufficient and the plastic valve product price decreased in the first half year, the performance is lower than anticipation, especially some export-oriented industries, such as shipping, forklifts and bulldozers industries have not went out of the recession yet. But the darkest period of blow molding machine industry has gone. In the rainy season in July, the chain decrease of the construction machinery products sales volume is normal phenomenon. Benefit from the infrastructure, the sale of cranes, excavators and engineering machiney cip represents positive growth for two consecutive months compared with the same period last year, but the sale of earthwork mechanical loading machines and bulldozers is average in performance. The increase of new project starting is forward-looking indicator, even if it falls, it also has high position in history, and the construction machinery sales of the second half year will not be slack in the off-season. The output of domestic CNC metal cutting machine tools has recovered, and the machine tool export of July this year first achieved the positive growth over previous year. The export demand has come down the bottom; rebound has not been obvious yet. The link relative ratio of South Korean construction equipment pvc fitting sales in June continued to move up, down 40% compared with previous year, and the decrease rate is narrow; the sales volume of Japanese construction machinery only achieved 30%-40% of last year's, and the machine tool orders are only 20% of last year's; machinery orders in Germany factory fell 46% compared with previous year, the decrease rate is narrow compared with May; American machine tool orders declined 64% compared with the same period last year.

September.15.2010 According to Customs statistics, in the first quarter of 2010 China’s import and export trade sum of construction machinery is US$ 3.76 billion, up 27.5% over the previous year. Of this total, the value of imports is US$ 1.77 billion, increasing 62.3%; export value of 1.99 billion, up 6.8%, and trade surplus is US$ 220 million, down US$ 550 million. From Jan to Mar of 2010, import volume of whole cip machine is 1.12 billion, increasing 72.3% than last year, accounting for 63.3% of total imports; parts import is 650 million, up 46.6%, and 36.7% of total imports. Of this total, crawler excavators pvc fitting imported 8,872 units, up 165% over the previous year, and accounting for nearly 60% of whole machine imports, which is an increase of 22 percentage points higher than previous year. Besides, some slitting machine products show good increase in bag making machine imports, such as high-powered bulldozers, graders, asphalt pavers, all terrain cranes, tower cranes, forklifts, pneumatic tools and spare parts. As for machinery export, the volume of whole machine is 1.27 billion, up 4.1% over the previous year, accounting for 64% of total plastic valve exports; parts export is 720 million, up 11.5%, with a share of 36%. Exports continued to grow slightly in March, in which warmer faster products include loaders, road rollers, excavators, tower cranes, forklifts, tractors, engineering drills, concrete mixers, rock drills, pneumatic tools and spare parts. In the first quarter, construction machinery imports and exports show three features. First, machines imports growth is far more than exports. Total trade surplus becomes narrow, there is even a month deficit in March, which is the first time since January 2006 totally 51 months; Second, imports of whole construction machinery increase substantially, holding a share of more than 60% of total imports, especially for track excavator (mainly second hand), the import appears blowout again, which is an impact on the domestic blow molding machine brands, causing strong reactions in the industry field; Third, the worldwide market is lack of effective blow molding machine demand, the rebound in exports get along slow and poor regularity, which indicates the market still exist unstabilizing factors.

September.06.2010 From Laser Institute of Shandong Academy of Sciences, reporters learned that their independent developed complete sets of metal tube online automatic detection bag making machine succeeded in the application. This equipment has not only broken foreign non-destructive testing equipment monopoly plastic valve in China, but also directly increased more than 5 billion yuan economic benefit each year for enterprises that use this equipment. China, the largest producer of metal blow molding machine in the world has more than 2,000 large and small-scale metal tube enterprises, only the cip output is about 100 million tons. In the absence of sophisticated detection pvc fitting technology, products are difficult to enter the international market. Meanwhile, the testing equipments that slitting machine import from abroad are expensive, and also can't adapt to China's metal tube. In order to solve the pipe fitting problem of metal tube online automatic detection, Laser Institute of Shandong Academy of Sciences launched the technological breakthrough. Through making use of through-type, point vortex, flooding, water film ultrasonic and other detection technology, they achieved the online detection on the surface and internal defects of metal tube in real time. This complete set equipment of automatic detection can hose analyze the reason why the metal tube doesn’t work, and remind producers to adjust the production equipment in time, it also can pick up the damaged metal tube away from the production line, which has greatly increased the rate of quality products. The equipment can test the metal tubes with 5mm to 1200mm diameter, covering all specifications of domestic metal tube at present, so it is the metal tube online automatic detection equipment with most widely range of detection diameter and highest detection accuracy currently in China, and it has reached the international advanced level. The institute said that this equipment can replace imported products, and the price of the equipment with same index is only one half of the imported equipment. According to incomplete statistics, the equipment has been promoted to more than 10 provinces such as Shandong, Jiangsu, Hebei and so on, nearly 200 sets equipment are used by more than 120 enterprises such as Baosteel, Baotou Steel, Panzhihua Iron and others, it has newly increased more than 5 billion yuan for these enterprises economic benefit, and also saved about 100 million yuan raw materials and energy. According to industry experts, the successful application of metal tube online automatic detection technology has increased the quality of domestic metal tube and enlarged the applications in high-end fields such as nuclear power tube, high-pressure boiler tube, which will make significant economic and social benefits.

September.01.2010 Mold materials has a wide range, from the general carbon structural steel, alloy structural steel, carbon tool steel, alloy tool steel, high-speed tool steel, stainless steel, maraging steel to carbide, insoluble alloy, high-temperature alloys, non-ferrous metals can be chosen, which are mainly alloy tool steel mold steel. With the development of China's mold industry, higher requirement need for quantity, quality, variety and performance of mold material, and the mold materials market also has a rapid development. For example: Mega Mould and Demark Blow Mold www.mega-machinery.com www.demark-group.com Mega Mould and Demark Blow Mold The domestic trial production of die materials lagged behind the demand of mold industry, mainly due to the follows facts: 1- Sales channel is not open and smooth. 2- Black round bar material is plenty, while the flat, fined, pre-hardened materials and products standard parts are lack. 80% of the die steel market in China is black round material, so the bag making machine customers have to reforge or refine the material, which caused low utilization of material and the long production cycle, even cannot meet the plastic valve needs of the slitting machine manufacturing mold. 3- Common-quality mold steel material is plenty, while high-quality ones are lack. And there are considerable part of the HQ mold steel needs go through the vacuum refining and electro-slag remelting. Some foreign cip companies require all the mold steel need electro-slag remelting as long as it’s cross-section is over 150mm in order to ensure high purity, high-density, pvc fitting high tropism, but in our country the die steel through the ESR only hold a small share.
