Expansion Road of the welded wire mesh

Resistance welding is a kind of welding method which presses the work piece between two electrodes and gives electric current to them, with the current flows through the work piece, the contact surfaces and the surrounding region generate resistor thermal effects and it is heated to a molten or plastic state, forming a metal binding. Working method of Welded wire mesh machine includes spot welding, seam welding, and projection welding, and so on.

Seamless welding skill shows excellent function in the mold processing, which improves parts precision and glossiness of appearance, and shortens the manufacturing cycle of the mold.
    

With the growing global market demand for high-quality parts, seamless welded steel net skill is more and more popular with customers, for it can improve part accuracy. Recently, the coalition partner of the Japanese company successfully developed a new seamless gantry welding skill, this company called Makino (Makino), and the seamless gantry weld machine it produces can effectively eliminate the welded joint, inform line and parting line between each mold.

The key to this process is to improve the processing skills and adopt vertical machining centers, with a whole new way to produce the mold. Moreover, it uses efficient heating and cooling cycle skills during the plastic injection molding process. This new skills are not yet pleaded patent; the Makino company develops some processing use one by one.

Seamless gantry weld skill can not only eliminate mold weld echoes to improve parts precision, but also do good to make the appearance more considerable. What’s more, this skill shortens the processing cycle of the mold by implementing efficient control. As the product produced by the process having a superior surface gloss degree, it does not demand a secondary sputtering and annealing, thus avoiding the change of the size of the secondary shortened constitute.

The welded wire mesh machine, of course, enjoys high popularity in the market mostly because it widely used for net products manufacturing in coal mines, highways, steel bridges, construction, etc. According to the industry injure early warning monitoring system from Ministry of Commerce, it ranks first in the factory price fluctuation, showing an increase of 41.50%. From this we can see that investing on this equipment is really a wise choice.

The booming situation of Hong Kong textile industry

The textiles industry – comprising spinning, weaving (weaving machine), knitting and finishing of fabrics have booming prosperity development in Hong Kong. Leading market for textiles exported from Hong Kong, accounting for more than 92% of the total textile exports. The textiles industry is one of Hong Kong's major export earners, accounting for 2.5% of the total exports for the first four months of 2012. Of the top 10 destinations for textiles exported from Hong Kong, nine of them are in Asia, with the Chinese mainland being the predominant export market.

Hong Kong is both a leading production centre and a global hub for clothing sourcing. As such, Hong Kong's textiles industry is well positioned to serve both local and overseas clothing manufacturers and merchandisers. Hong Kong's textiles industry serves not only the local clothing manufacturers, but also those on the Chinese mainland and other offshore production bases. Hong Kong’s textiles industry is reputed as a supplier of quality dyed and printed fabrics, also in cotton spinning, denim weaving, panel knitting and cotton knit manufacturing. 

Other major export markets of Hong Kong textiles include Vietnam, Indonesia, Cambodia, Bangladesh, Thailand, Sri Lanka, the US, the Philippines and India. Because of Vietnam’s cheap labour and WTO membership, many foreign investors, including those from Hong Kong, have set up garment factories there.

While many Hong Kong textile machine manufacturers and traders supply their products to the clothing manufacturers in Asia, particularly on the mainland, international textile companies are also using Hong Kong as a gateway to promote their products to other Asian economies.

This gives rise to sustained demand for textile imports, making Vietnam the second largest market for Hong Kong’s textile exports, after the Chinese mainland.

Caterpillar bulldozers correct driving operation and use of technology

Bulldozer and caterpillar excavator sales growth goes to a positive number. Infrastructure recovery appears gradually effect. Although excavator and wheel loader sales picks up speed is lower than the normal seasonal characteristics, but in circumstances of infrastructure enhancement relative steady picks up, the future engineering mechanical power is still real estate. Synchronous indicators are real estate new start rate; leading indicators is real estate sales.

1, advance and retreat

Variable speed hanging block, should first will throttle lever is pushed ahead to the idle position, then the main clutch lever push to the front, make the main clutch, the main clutch inside small brake in the role of the transmission power input shaft stop turning. At this moment, but will change post correctly moved to shift required, then in a bar in forward or backward position (bulldozer forward, will be in a bar pull back, back when he is pushed forward). After put into gear, throttle lever pull back, in order to increase the engine speed, and smooth connection of main clutch, bulldozers start driving.

When driving, should be the main clutch lever pull to the side, and put it not half joint position. For the Lord clutch half joint will aggravate the friction plate wear. Transmissions usually have five forward gears and four back in. Use a lever can change bulldozers and excavator's direction of travel.

In the work, should as far as possible with the highest speed operation, in order to improve work efficiency. But driving personnel should always pay attention to engine operation is normal or not, found that engine overheating and exhaust smoke, should be appropriately reduced speed.

2,turn to veer

Travel in turn can be turned to the edge of the steering clutch lever pull back, make the steering clutch, and the corresponding side of the track speed slow, bulldozers began to move. If you want to make a bulldozer twister, in addition to separate steering clutch outside, still should tread down corresponding brake pedal, generally only in Ⅰ stop running to allow for quick turn. Do not use brake, foot should not be kept on the brake pedal, otherwise, it will lead to brake band wear and fuel consumption increase.

Bulldozer steering should be smoothly on brake pedal, in order to avoid turning beat occurs. After the turn should be loose brake pedal, and then release lever. If the turning radius is bigger, it doesn’t have to step on the brake pedal. No heart, avoid by all means make bulldozer high speed in situ rotary, lest track derail and cause accidents.

Crawler excavator win the honor of 2012 red dot product design

Liebherr A918 Litronic compact crawler excavator becomes the winner of the honor in the competitive and influential 2012 red dot product design awards.

A918 Litronic compact crawler excavator was awarded the global industrial design which was the most prestigious red dot product design awards

Liebherr newly research and development of new A 918 Litronic compact excavator combined with standard excavator and small excavator performance characteristics. A918 innovation design based on a new design concept, the design concept will be applied to the Liebherr earth moving equipment the entire product series, now for the first time in wheel excavator design into practice. The design concept is more emphasis on visual effect and practical and can be applied to: track excavator, crawler excavator and wheel loader, crawler bulldozers, caterpillar loader, telescopic boom loader, articulated dump truck and handling equipment, etc., Liebherr group appeared the characteristics of the products.

Red dot design award is one of the most famous international design competitions. The winners were decided by well-known experts composed of a grand jury review. winners should have a high level of creativity, innovation and product quality. These strict criteria constantly adapt to improve appearance, technology, manufacturing, society, environment and ecology as the latest research and development requirements. These principles form a framework for the jury of the experts to individual interpretation. Experts From a number of countries selected 2012 Redot product design award winner from submitted a total of 4515 design works.
