In the past decades, die and mould industry keep increasing with a speed of average 15%, and the forms of ownership in die and mould industry changed a lot.

With the ever-increasing integration with international companies, the competition among companies is more and more fiercer, manufacturers begin to realize the importance of the quality and cost of the products, and the manufacturing of the die is the most important link in the whole process. Now more and more die companies invest more money to increase die technology. Some die companies have popularized some software such as two-dimension CAD, UG, Pro/Engineer, I-DEAS, and so on.

The development of the die technology should adapt to the following requests, we should short the manufacturing time and price, improve the precision and the quality of the product, in order to reach these requests, firstly, we should popularize the CAD, CAM, CAE technology, now according the development of the software, the condition for popularizing the CAD, CAM, CAE technology is ripe, all kinds of training centre are committed to teach workers how to operate the software, which makes the development of the software keep increasing. Secondly, the high speed milling technology gives rise to the change direction of the die and mould industry. The technology of high speed milling spreads all around abroad, this causes the increase of working efficiency and can get low surface roughness, which makes the development more agile, more intelligent.

Thirdly, better material and advanced surface processing technology, it is necessary to select choice steel and suitable surface processing technology to improve the life of the die, so when the trend of die’s heat treatment is through using vacuum technology.

Fourthly, the quality of die’s surface plays an important role in the life of the die, so it is a good idea to do research about grinding automatically and intelligently, which can replace manual operation.

Fifthly, the development of automatic manufacturing system in die and mould industry, this is the target for the long developing plan, automatic manufacturing system about die should combine more than one machine tools, the system should have location chuck, positioning plate, tool database, the entire numerical flexible synchronous system and quality-monitoring control system.

Above is the trend and current situation of die and mould industry.

How bout the current situation and analysis of our country’s construction machine leasing industry? What is the market demand and the existing issues about construction machine leasing industry? Now China construction industry association does a survey about the current situation and future development of China construction machine leasing industry, the survey is done by a questionnaire and the interview with the important companies, 63% of the companies which join in this survey are construction machine leasing companies, the rest of them are construction enterprises.

Now we talk about the current condition about construction machine leasing industry. Our country’s construction machine leasing industry starts later than foreign countries’, and the scale is not big enough. The origin of this industry dates back to the 1990s, and with the ever increasing development of the enterprises, state-owned, private, joint venture, personal construction machine enterprises develop rapidly, for example, in Beijing, the numbers of the companies which is engaged in leasing are 400.

Here are the questions which the enterprises care about.  The key to determine whether the transaction is success or not is the leasing price, and the proportion of this factor is about 25.8%,which is followed by the band reputation of the leasing company, which is about 20.4%. The questions which the enterprises care about are rent arrears which occupy 50.7% of the whole, the standardization of the market which is 46.4%, the third one is the development of the band.

According the survey, here are some advices for the future development of this industry. Firstly, we should change the business concepts, and create new kinds of leasing mode. Secondly, build new leasing enterprises which are more professional and have their own bands and scale. As is known to all, the quantity of enterprises which are more professional and have their own bands and scale in machinery represents the developing level of the whole machinery. Thirdly, apply scientific managing method, and lower the credit risk. Fourthly, create differentiated services, and improve the competitiveness of the enterprises. Focusing on selling and ignoring service is the general problem existing in today’s construction machine leasing machinery, the conception of doing well in service is not only focusing on improving the satisfaction of the existing service, but also thinking about how to apply customers with underlying demand. So improving the service quality and making diverse service projects to satisfy customers will increase the quantity of the leasing transaction.

In a word, let government authorities, industry association and enterprises cooperate with each other fluently, and make a just, fair, orderly environment for the leasing market.

As is known to all, the heavy machinery can be simply divided into several groups such as construction machinery, engineering machinery, crane, metallurgy machinery and so on, and according to the application of the product and the actual use of the product, we can divided it into other catalogs.

Today, we’d like to introduce something about construction machinery, first, the definition of construction machinery. Those machines which are used in the process of construction is called construction machine, and these machine can make the building more stable, and make the time of completing the building shorter. Construction machinery can be subdivided into construction device, road equipment, garden machine, crane, excavator, earth-moving machine, and so on.

Currently, the globalization of the economy is the general trend of the world economy, since China joined the WTO, the speed of China’s integration into the world economy accelerates rapidly, so from now on, one trend of our country’s construction marketing is toward internationalization, standardization and the diversity of the marketing. Because of these changes in construction marketing, it affects several aspects of the construction marketing in China. Firstly, the general trend of investment in our country’s marketing is increasing, and it does bring the opportunity toward the development of the construction machinery. Secondly, the integration of the domestic and overseas market, and it did bring great opportunity and challenge to enlarge the international contract market. After we enter the WTO, all the members which join the WTO have to share information with each other, and have no excuse to turn down members illegally. Because the reduction of the tax, we can low our cost, in that way ,we can also enlarge the importation of the material, all these issues is benefit for the development of the economy.

Thirdly, the environment of the construction market is becoming better, at the present, a lot of issues in construction market exist, but the general trend about domestic market is towards the sound, the standardization and the perfection of the one.

Fourthly, more and more foreign investment flow into construction companies in China, and it brings the fierce competition among construction market, through the competition, we can reduce the gap between domestic and overseas marketing.

In a word, from now on and in the following years, it is a good opportunity to develop the construction, although we may meet a lot of challenges, we can tackle them and have our own market occupation in the construction market.

Nowadays all kinds of machine tool have been used in manufacturing industry, such as turning, milling, grinder, planer, and so on, but among them, milling machine is the most useful machine tool, because we can produce complex surface through using milling machine. Today, we will study and know a new kind of milling machine which is famous for its high efficiency and cleanness, it is called whirlwind milling machine. Whirlwind machine is a kind of machine which we add the high speed thread devices to normal turning machine, through using CBN tool which is clamped in the high speed milling cutter, we can mill the thread on the workpiece, because of its high speed which is more than 400m/min, high working efficiency, and cool strategy which use compressed air to get the chips out of the thread of the workpiece, it is becoming more and more important and popular. Whirlwind machine can also realize dry cutting ,heavy load cutting and ultra high speed cutting, the surface roughness can reach 0.8 um, because the turning speed of spindle is slow, so the motion accuracy of machine tool is accurate, and we can get high dynamic stability. Here are the motion of the whirlwind machine, the main motion is the high speed turning of the mill cutter, the supplementary motor is the slow turning of the machine tool with clamped workpiece, the feed motor is the slow movement of the mill cutter at x direction, and we should adjust the angle of the mill cutter according to the thread lead angle. The application of the whirlwind machine is spreading all kinds of machinery, for example, the sprite which we drink when we feel thirsty is involved in using this technology, we can manufacture the cap using whirlwind machine, and we can also manufacture all kinds of bolts and ball screws. On the whole, the whirlwind technology is widely used in daily life, and we can keep improving the feature of the whirlwind machine, in that way, we can keep doing great in machinery.

On 16 ~17 of January 2009, a “Chinese Construction Crane Technology Innovation Strategy Alliance Seminar” was held in Liaoning, Dalian Province. Many representatives from XCMG, Jingcheng Heavy Industry, Liugong, Sunward, Foton Lovol, DHI·DCW Group Co., Ltd. and many other large construction machinery enterprise, as well as many experts and professionals from Dalian University of Technology, Tongji University, Tianjin Engineering Machinery Research Institute and other research institutes attended this seminar. The seminar focused on the establishment of innovation and strategic alliance in the construction lifting machinery industry.

At present, during a critical period of Chinese economy, China is vigorously expanding domestic demand, accelerating infrastructure construction and upgrading industrial transformation. In the next decade years, the investment in large infrastructure projects will continuously increase, and the roads, railways, urban construction, new energy, water conservancy projects will grow constantly. The peak of large-scale urbanization will come. In face of the great market prospects, Chinese enterprises should work together to build a community to conduct production and technology research, through which forming core competitiveness in the industry. The crane enterprises, parts factories and research institutes should strengthen cooperation with each other and promote Chinese crane industry to develop from the phase of imitation and low-end products to creation and high-end products.

Chinese construction machinery industry has been developing rapidly for consecutive 6 years. In accordance with industry practice – the equipments need major overhaul after used for 5~8 years, so it means that the demand for second-hand construction machinery will increase significantly. According to relevant statistics, the trading volume of second-hand construction machinery in China has exceeded 100 billion Yuan in 2009, with an over 20% growth rate. Some industry experts believe that Chinese second-hand equipment industry will realize industrial management and form an industrial chain, which integrated with recycling, processing (maintenance, renovation, re-manufacturing), distribution, import and export as whole. However, without assessment criteria and clear property rights, Chinese construction machinery has not been entitled the right credit sales through bank mortgage and finance lease, which stop some high-qualified equipments entering market.

China “General Principles of Circulation and Technical Specification of Second-hand Equipment” has took effect on March 1, 2010. Chinese second-hand construction machinery will develop better in the future.

China has announced an increase in its product line with two new products:

One is threaded into the type of nozzle 06E,

The other is applied to needle-type hot runner system bolt type cylinder PNC30.

Threaded into the nozzle 06E

Nozzle 06E flow channel with 6mm diameter, length range 60-200mm, the maximum injection volume of each nozzle 100g, use of external heating, with easy-to-one replacement of the heater and easy replacement of the thermocouple. At the same time as the nozzle plate with screw fixation in the shunt,

solved slide systems stack size with the poor as a result of leakage of material problems.

When the new needle 06E jet and bolt type cylinder with a hot runner system in the same time,complete hot runner system can be pre-connected lines and pipelines, “plug and play” installation of mold.

Bolt type cylinder PNC30

PNC30 got a lot of features, including:

Demolition, adjust the valve needle without demolition template;

No need to remove the valve needle demolition template;

Bolt design, no lateral force / load to the valve needle, the valve needle easy to align;

Through the backplane to provide cooling systems, valves, needle drivers need to provide cooling pipe.

U.S. construction equipment manufacturers suffered an estimated 43 percent decline in business in 2009, according to a survey conducted by the industry trade group Association of Equipment Manufacturers.

Respondents to the survey of U.S.-based companies on average expected a 5 percent increase in business in 2010, followed by gains of 15 percent in 2011 and 14 percent in 2012, not enough to erase severe losses of both business and jobs. The outlook for the export-driven industry is only a little less dismal outside U.S. borders.

For Canada, 2009 business decreased an estimated 34-percent overall. Respondents expected a 2010 increase of 7 percent, a 14 percent increase in 2011 and an 11percent increase in 2012.

Industry business to the rest of the world was expected to close out 2009 with losses of 34 percent, followed by a 2010 gain of 7 percent and growth of 13 percent in 2011 and again in 2012, according to the AEM survey.

“Even with a modest rebound in the next few years, the construction equipment industry will still be down by double digits, and there will still be double-digit industry unemployment,” said AEM President Dennis Slater. “This is not surprising given the continued instability of the housing market and no long-term commitment to America’s roads, rail, airports, water distribution and ports to move people and goods efficiently and safely, and to compete effectively in the global marketplace.”

Survey respondents said the state of the overall economy, including credit availability, interest rates and consumer confidence levels will influence construction equipment sales in the coming years. Housing starts and highway funding levels will also play a major role in any business rebound. Other major factors are the strength of the U.S. dollar and international business, since the industry is export-intensive, said AEM.

AEM is the North-American based international trade group representing the off-road equipment manufacturing industry. Each year it surveys its construction equipment manufacturer members about expected sales of the machines that build and repair roads, bridges, houses, offices, schools and other infrastructure in America and worldwide.

FORT PIERCE — The second phase of earthquake relief for Haiti is under way as 200 tons of heavy equipment and building materials are being loaded onto a cargo ship Monday at the Port of Fort Pierce.

Once full of supplies for Samaritan’s Purse International Relief, the Caribe Star 1 is expected to set sail Monday night and arrive Friday morning at the dock of a former cement factory near Port-au-Prince.

As the supplies and equipment were being positioned at the port Monday morning, Luther Harrison, director of North American projects for Samaritan’s Purse, said the Boone, N.C.-based charity already had a team of 60 in Haiti when the earthquake hit.

Since then, he said, 19 medical personnel at the Baptist Haiti Mission Hospital in Fermathe southeast of Port-au-Prince have been treating wounds, performing surgery and caring for the sick. Also, 40 Samaritan’s Purse staffers are distributing rolls of plastic for temporary shelter, solar flashlights, blankets, community water filters and water purification packets.

“We’ve been partnering with (Fort Pierce-based) Missionary Flights International to fly in food and medicine,” he said. “Now it’s time to send in the big stuff, the stuff that’s too big to put on a plane. We’re coming out of the emergency phase and into the recovery phase. The whole infrastructure down there has been destroyed, and we have to rebuild every aspect of it.”

Dr. David Gettle, chief medical adviser for Samaritan’s Purse, said in a prepared statement that wounded and sick earthquake survivors “are coming to us by the busloads. Without the ability to transport supplies through the rubble-strewn streets, we will not be able to treat them.”

Cargo on the Caribe Star 1 will include excavators, hydraulic hammers, a bulldozer, dump trucks, a tractor-trailer, flatbed trucks, vans, pickup trucks, Bobcat loaders, plastic pipes, plastic sheeting and lumber.

Harrison said half the vehicles were bought just last week at sites as far-flung as New Jersey, Arkansas and Virginia.

Getting all the equipment to Fort Pierce in a hurry should have been a logistical nightmare for the faith-based nonprofit headed by Franklin Graham, son of evangelist the Rev. Billy Graham.

“God has been steering us in the right channels,” Harrison said.

Ships typically located throughout the world carrying combat loads were being loaded with construction equipment bound for Haiti.
Depending on weather, the three Military Sealift Command ships – crane ship Cornhusker State and motor vessels PFC Dewayne T. Williams and Cape Ray – could be headed to Haiti Tuesday with the supplies to help clear the rubble and build temporary piers and causeways to deliver more supplies.
Already, one of the ships is slated to return to Norfolk to pick up additional supplies and make another trip to Haiti, said Lt. John Fairweather, detachment officer in charge of Command Naval Beach Group 2.
“Normally, Hampton Roads doesn’t see these ships,” Fairweather said.
Overall, he said the crews are looking forward to helping with the relief efforts.
“Not one of these people has a problem with going,” he said. “It’s a heartfelt thing.”
