On the specific applications of laser processing in the plastics industry

    Core Tip: Since the reform and opening up, the plastic industry as traditional industries have been sustained, rapid and healthy development for over 30 years. But the arrival of the international financial crisis, resulting in various industries around the world have different degrees of contraction in global demand structure is facing change, it will also lead to a re-shuffle of the plastic industry. The plastics industry must reduce manufacturing costs, shorten the development cycle, improve the core competitiveness of the plastics industry in order to completely overcome the global financial crisis, present this once in decades.

     
    The laser processing using a laser beam projected onto the thermal effect of the surface to complete the processing, including laser cutting, laser engraving (laser marking).

    Laser with high brightness, high directionality, high monochromaticity and high coherence of the four characteristics, so give the laser processing of plastic products to bring some of the other common processing methods do not have good features.

    Laser processing in the plastic industry specific applications as follows:

A laser cutting plastic products:

    Plastic laser cutting laser beam is focused on the surface of plastic materials using high-temperature properties of the laser material melting, and the compressed gas of the laser beam to blow away the molten plastic products, and the laser beam and plastic products along a certain trajectory for the relative motion, thereby cutting process to form a certain shape.

    Plastic laser cutting processing advantages:
  
    Specific applications of the laser cutting of plastic products:

    Laser cutting plastic outlet: the quality of laser cutting, belonging to non-contact cutting and trimming a small heat-affected, the basic workpiece thermal deformation, completely avoid the collapse of the edge formed by blanking die, laser kerf smooth, generally do not the need for secondary processing.

    As shown for the laser cutting plastic buttons outlet:

    Laser cutting manufacture new plastic product samples: Laser cutting can improve the speed of new product development: the formation of product drawings, we can immediately after laser processing, and samples of new plastic products in the shortest possible time.

In recent years, as competition intensifies, lighting producing areas have during the adjustment of industrial layout, while the LED has become the object of pursuit in the various producing areas competing. Review a series of actions done by the various production areas in the first half of 2011, in addition to the Light Town focus on strengthening market supervision, standardize the work, the other major producing areas in the LED industry, the construction of a large number of inputs, The results also glamorous.

 

 

Ancient town of the founding

With the increased competition of Jiangmen, Dongguan, South China Sea and other regional brands, the town dorsoventral by hostile forces. But after nearly a decade of rapid development, the town is faced with the optimization and upgrading of industries. Recalling the first half of the town, have done a lot of efforts to strengthen government supervision, standardize the market, from the initial results to remove the quality of yellow card to the intellectual property rights quickly center in the town was set up, can get a glimpse. The lights are direct sales base for the establishment of 100,000 square meters of high-profile store of childbirth has also become the town and strive to upgrade the epitome of a breakthrough.

Specification – the market waits for no man

According to incomplete statistics, at present, the town in the register of lighting business has nearly ten thousand, but less than 10% the proportion of brands, a large number of workshops three companies were removed from low-quality, low-priced products in the rivers and lakes, thus affecting the ancient the overall level of the town\\ s lighting products. In 2009, the town, Guangdong Province, junior college student identified as provincial crackdown deadline for correction of the area, and given the quality of yellow card, this is undoubtedly the town cast the shadow of the layer disgraceful.

Not silent in the outbreak, and in silence perish. The bitter experience of Guzhen Town government has established a quality improvement work leading group, improve the enterprise file, and resolutely to clean up the \"three noes\" enterprise. More than a year of renovation work, the quality of Guzhen lighting products gradually picked up. The first quarter of this year, the town lighting products, sampling average pass rate of 73.4%, increased by 17.5 percentage points higher than the city\\ s lighting products over the same period sampling average pass rate of 14.3 percent over the same period last year. Among them, the pass rate of 90.6 percent in March. The ancient town successfully remove the quality of yellow card.

Actively build a trading platform

Influence because of the lights are only limited to professional businesses, the lack-end consumer\\ s right to speak, and this year, town lighting Baotuan operations, collective going out \"strategy has been implemented, the lights are (Beijing, China), direct sales base was officially settled Beijing. It is reported that the total construction area of ??more than 70,000 m2, is a set of brand lighting , retail, wholesale, project and export in one five-star direct sales platform, will make full use of the base for direct marketing and corporate brand double strength prove safety terminal, become ancient town lighting industry from the industry supply chain, enterprise clusters bold attempt to upgrade to the integrated service platform.

Meanwhile, the newly laid the foundation stone of the people emerging Plaza construction project, planning an area of ??100,000 square meters for building lighting stores – the ancient town-intensive high-end stores adding new army.

Ancillary services immediately and on

Mostly in the town, small and medium enterprises, many enterprises are facing financing problems. March 15 this year, the Association of Lighting of Zhongshan City, Guzhen Town, Chamber of Commerce joint Zhongshan Branch of the China Postal Savings Bank, Standard Chartered Bank (China) Co., Ltd. Zhuhai Branch agencies convened to SME financing plan promotion, to assist member companies broaden the financing channels and regulate the orderly operation.

In order to solve the problem of town lighting enterprise rights difficult, in June, the rapid Rights Center of Zhongshan (lighting) intellectual property in the town was established, which is currently the only established for a single industry, fast rights institutions, sets of patent applications, rights assistance, mediation and law enforcement, the administration of justice in one, thereby greatly enhancing the efficiency and speed of corporate rights.

The Nanhai focus on the development of the electric light industry

Currently, the South China Sea has nearly 400 lighting companies, about 100 Among them, the light source enterprises, commercial lighting and supporting more than 300 enterprises. In recent years, the South China Sea to closely follow the trend of the times, is actively building the electric light industry base.

Union, the Association willing to nurse

In January of this year, will Foshan resulting in national industry think tank to create a new platform for industrial development, the the \"LED Lecture\" series of training activities in the South China Sea, South China Electric Light Source City opened the prelude. The training will focus on the LED standards and testing, LED interior lighting intelligent and high-power LED development trend of key issues, aimed at raising awareness of the technical problems, develop ideas and methods of the enterprises to cope with problems accumulated diversified enterprise of talent. It is understood that the LED large auditorium, \"a series of activities will be normalized and plans to hold one every two months, has been held for three.

Electric light sources in the South China Sea Association is also actively provide caring services for the enterprise. Guangya Exhibition, Foshan Nanhai Museum display area of ??1055 square meters of brilliant debut, 22 appliance light companies Baotuan exhibitors, and behind this is inseparable from the active organization of the electric light in the South China Sea Lighting Association. It is reported that the Association is actively working with the South China Sea area and rout the streets to do to apply for special funding, the Association will show after the government introduced a series of supportive way to the District government for the enterprises to apply for booth fee subsidy.

The four-day 16th Guangzhou International Lighting Exhibition has ended, the reporter learned from the exhibition site, the participants, more than 1,800 lighting companies, more than half engaged in led lighting industry, the industry refers to the traditional incandescent lamps will fade out. LED lighting will become the mainstream lighting market. But the reporter also found that the upstream core technology is still the monopoly of several major foreign industrial giants, the majority of domestic LED enterprises become the industry downstream assembly plant.

It is understood that the output of the LED industry in China is the world s first, the output value ranked second in the world. Wu Wenfeng, Vice President of Tsinghua Tong Fang Semiconductor Lighting Systems Division, expects 2011 output value of China s LED industry will reach 180 billion yuan. Faced with such a huge market cake, in addition to domestic enterprises have to force the foreign giants will also shift the focus of the domestic market, the reporter learned at the scene, GE Lighting in this exhibition launched two new LED modular street lamps and angle light-emitting bulb Universal, will take the lead in the Chinese market as early as in the other markets of the Asia-Pacific region, synchronized with the U.S. market, which shows the importance of the Chinese market.

However, domestic enterprises want to break out the attack by foreign giants still difficult present, the structure of the domestic LED industry is still focused on packaging and downstream applications link in the upper reaches of the wafer, chip, two key areas of strength seems to be rather weak. According to Wu Wenfeng, epitaxial wafers, chips, packaging and other technical aspects, there are many patents, the multinational giants such as U.S. SemiLEDsCorporation, Netherlands, Lemnis companies are building huge patent pool, thereby threatening the long-term development of China s LED industry.

Upstream monopoly so that the domestic cost of LED lighting has been high, the general public is also difficult to accept the high price, is not conducive to market penetration. Shenzhen pole into the photoelectric Managing Director Chen Linchun told reporters LED market share of about 10%, GE Lighting President of Asia Pacific Bijan LED popularity of take some time, and he expects the LED proportion is expected to reach 25% in 2015.

At present, Tsinghua has formed a LED epitaxial wafers, chip manufacturing and packaging the end product production and applied to a complete industrial chain and large-scale production of commercial and urban landscape lighting, and has LED wafer and chip manufacturing patent nearly Wu Wenfeng introduced one hundred, the 2011 LED industry output value is expected to exceed $ 2.5 billion.

Analysis of the industry, China s LED industry and developed countries is almost the same starting line, which gives opportunities for domestic enterprises to participate in global competition, will also industry reshuffle, the majority of core technology, enterprises will be reduced to the downstream industries assembly plant, the passage of time and then collapse or transformation of the loss of competitiveness. At the same time, the industry also called for the LED industry standards as soon as possible to the LED lighting technology and products to fish, uneven dilemma, regulate the market, promote the healthy development of the domestic LED industry.

LED industry in China since 1990, began to rise around 2000, many flocked to small and medium enterprises, investment in the LED industry, LED industry, intense competition, product prices come down gradually, and steady development in 2001, according to industry association statistics, the 2009 gross domestic The LED applications, the production value reached 14 billion yuan, of which full-color display applications, the size reached 6.5 billion yuan. Promote the enactment of the measures in 2010, with the government\\ s economic boom high of the LED industry, attracting many investors to enter, but even debt crisis and other adverse factors, most enterprises are struggling at the edge of collapse.

According to statistics, the LED industry in the first half of 2011, signed planning investment amounted to 1,184.98 billion yuan, a year-on-year increase of 26% compared to the downstream market is clearly not open. LED products rely more on local government municipal works to digest the expensive price makes civilian is still out of reach, by the weakness of the international market, LED exports also suffered poor. Shenzhen, more than 1,300 LED business the vast majority of small and medium-sized enterprises, can not be able to survive, industry closures has already begun, the industry is facing a brutal shake-out. At present, although the LED as a whole showed the trend of rapid growth, but every day in Shenzhen LED enterprises are facing bankruptcy or winding-up.

According to the National Development and Reform Commission predicted that the \"12th Five-Year\" period, LED industry is expected to achieve the goal of quadrupling. Penetration rate of 20% to the end of 2015, China\\ s LED lighting. Industry is generally estimated that more optimistic, expected in 2015, the outdoor LED lighting penetration rate of 60% -80% penetration rate of 25% -30%, indoor commercial LED lighting, indoor home LED lighting penetration rate of about 5% – 10%, the overall penetration of the Chinese market, LED lighting will reach or exceed 20%.

Policies to promote energy conservation, leveraging LED lighting applications market is conducive to the industry and long-term development. A number of semiconductor lighting guide policy in the fourth quarter is expected to be launched soon. It is learned that the Ministry of Finance is the competent department in conjunction with the Development and Reform Commission, plans to subsidies is expected to launch in the fourth quarter of semiconductor lighting products. In addition, the Ministry of Science and Technology \"10 City,, 10000,\" the guidance of the implementation of the measures is expected in the fourth quarter release.

It is understood that the LED production process can be classified as a substrate manufacturing, production of epitaxial wafers, chip manufacturing, chip packaging and LED products, the production of five stages. Among them, the substrate in the LED chip play the role of bearing and fixed, up to 92% market share of the sapphire substrate.

Topology Research Institute is expected to LED lighting market in 2012 in mainland China will be a large outbreak, the market will grow from $ 2.8 billion in 2011 surged to $ 8,000,000,000, an increase of 185%.

Substances composed of molecules, the molecules are composed of atoms. In fact, the atom is not composed of the smallest particles of the substance, which is composed of nuclei and nuclear rotation around a group of electronic micro-systems. The rotation of the orbit is a set of concentric park space. The concentric Park, a limited number of allowed outside the orbit of the other tracks do not allow the electronics exist.

Atoms with internal energy, the size of the internal energy can not be continuously changing, step by step separate. This separation of energy called energy levels. Electronics in which the state determines the energy level high and low. Under normal circumstances, the electronic is always located in the inner orbit, this state is called the ground state or steady state. Always the vast majority of electronic group in the ground state atomic system. No external force, the inner electrons do not run up the outer layer. In other words, low energy level of electrons do not automatically went to the high energy level up.

To be external when the electronic ground state with the appropriate way to give a certain energy, such as light, electron impact, chemical action or heat, etc., will be excited to high energy level up. Contrary electronic atom s own internal contradictions, will spontaneously return to the low-level energy level up, a process called spontaneous transition. Transition refers to the micro-particle system to do a state transition from a particular state. Spontaneous transition of the internal energy of the atom is reduced, the excess energy will be released. The release of two forms, one hot, one is light. Called non-radiative transition to the heat, light called spontaneous radiative transition, the radiation that the spontaneous emission, the general light source such as lamp light spontaneous transition.

Of each atom in the atomic group outermost electron eclectic, radioactive materials may also contain a wide array of elements. Each atomic electronic orbital semi-major does not equal the energy difference between the energy levels are not the same. Electromagnetic radiation by atoms Group, the intensity of each mode, frequency, phase, direction may be vastly different, so the spontaneous emission in optics called non-coherent light. Fluorescent lamp radiation are non-coherent light, light and radio waves, microwaves, a form of electromagnetic energy, although the effect of electromagnetic radiation with frequency, but the essence of all the radiation processes are the same.

The generation of laser is the use of substances called by the stimulated emission characteristics of all electronic material not subject to external energy excitation kibbutz in the ground state level A by the outside world energy excitations, part of the electronics will rise to the energy level of the level of B, then they will soon be the form of fluorescent transitions, decline to level C material. The residence time of the electrons in the highest level by stimulation is very short, about 10 to the minus eight s. But some substances when the electronic transition to the high energy level can stay longer. Such as the ruby ??chromium ion will be able to stay a few milliseconds, and thus where the formation of a stable residence status (metastable).

Electrons from the metastable further transition to the low energy level, a photon. If the photons in the optical resonator (at both ends of a cavity mirror), reflected back, it will induce the transition of the same nature, resulting in the same frequency with the phase of the photon. Evoked the role of these two photons will resurgence, it goes on the same frequency will produce a strong enough, with the phase of light shot out from the optical resonator has a semipermeable mirror, which is stimulated emission.

Subject to repeated stimulated emission of light by multiple resonant cavity feedback, enlarge and form a bunch of the same frequency and same phase in the same direction, a strong optical flow, from the semi-inverse semi-permeable lenses in the injection, which is a laser.

Born in 1900 the Hungary Englishman Gabor (DGabor,) invention of holography, for which he obtained in 1971 the Nobel Prize. 1962 the enforcement University of secret security Leith (ENLeith), and the the upa Turk Nice (Jvpatnicks,) using laser capture success of the first practical hologram, ie off-axis-type two-beam holographic picture. Holography, the English name called: "Holography" for the Greek, meaning all records that record all the information – amplitude and phase. Can reproduce the entire object as the use of any district in the hologram laser photography. Therefore, as long as a small part of the debris to save the film will be able to reproduce the original all the scenery, which is the source of holography is usually understood as all the information.

Welding equipment survey data, 33 percent of the saw blade has a laser welding machine, 13 percent of companies are Buying a laser welding machine, 13 percent of the company\\ s future plans to buy a laser welding machine, 41 percent of businesses not currently clearly the intention of the company. Market share in terms of which 54 percent of the market in Germany Feiyu, Wuhan Jinshi Kai has 27% market, other companies (Wuhan Fali Lai, etc.) accounted for less than 2% of the market. Laser welding technology is an export of the technical threshold of the saw blade industry, product and low grade watershed collar than laser cutting, so a lot of blade desire to buy laser welding, laser welding equipment company will select the outside processing .

Third, the hard materials industry development status

Blade industry is a major consumer of hard materials industry, the hard materials industry in 2005, although internal and external difficulties, but still achieved a total industrial output value, sales revenue growth rate of 26%, a small amplitude slow the still rapid growth. Product mix improved significantly, a substantial increase in technical level, production costs have fallen dramatically. The cut-throat competition of diamond saw blades for many years led to the 2005 U.S. anti-dumping battle of Diamond Saw Blade; grasp the rapid development of advanced powders and indirect heating method of producing diamond enterprise, causing a \"big reshuffle\" of the diamond-producing enterprises, a large number of technology research and development behind, unable to grasp the advanced manufacturing technology companies has been eliminated. The high wind and waves, the stormy situation has flooded a lot of enterprises, to exercise and improve as the industry as a whole, with international advanced level, the largest amount of times a high quality diamond products have made a breakthrough and has high volume production. the end of the unique cubic press not produce 30/35 and to the history of the coarse high grade products, aroused the close attention of the international counterparts, and completely changed the situation of the international peer contempt diamond equipment and technology, world-renowned two of the three diamond factories in China, cubic presses the production of diamond technology procurement and research, and another is re-sold part of its diamond industry.

3.62 version of wavefront aberration wavefront surgery (CustomVue Lasik), also known as personalized vision laser correction surgery, Nuctech the Visx Company production, with CustomVue technology Wavescan found in a Wavefront system to guide the Visx Star S4 excimer laser system correction of myopia surgery. At present most of the world\\ s ophthalmologists favor, is universally acknowledged myopic refractive correction of the \"gold standard\"! Nuctech Visx distributor in the Asia-Pacific region – Hua Ying sector projects director of Confucius filial Yang told reporters: the continent of many medical institutions publicity can Shixing Bo aberration guide myopia surgery, on the one hand, to prove the superiority of wavefront technology recognition, on the other hand, economic and technological strength of restrictions to make the continent more than one thousand excimer laser center truly wavefront capacity is a paltry 6. The reporter learned that the the Changzhou laser specialist hospital introduced the VISX wavefront aberration of 3.62 version system is the only one in Jiangsu Province.

Heavy glasses to bid farewell to the traditional Lasik surgery, its security and stability of the effect has been certainly, but part of the postoperative daytime eyesight is very good, but poor vision at night or dark environment, accompanied by the glare, halos, ghosting symptoms such as severe cases affect traffic safety. Eyes scientists found that the higher-order aberrations of the eye optical system at work. A refractive defect of the eye is the low-order aberrations (nearsightedness, farsightedness, astigmatism) and higher order aberrations (spherical aberration, coma, trefoil aberration, etc.) exist, the ratio is 92 ~ 93% and 5 to 7 percent, before undergoing a surgery, the visual impact of the main reasons accounting for 92 to 93 percent of the low-order aberrations, that is, nearsightedness, farsightedness or astigmatism, through the traditional Lasik surgery to low-level aberration correction accounted for 5 to 7 percent the proportion of higher-order aberrations after the visual impact of the main factors resulting in decreased night vision, visual discomfort and visual quality issues. The traditional Lasik surgery has been powerless. Wavefront surgery according to the personalized features of the human eye, the low-level and higher-order aberrations amendment to make visual quality reached unprecedented new heights, whether it is day or night, a higher visual resolution, contrast sensitivity stronger, clearer visual.
