uPVC profile cutting machine is major and essential equipment for manufacturing uPVC windows and doors. Cutting is the beginning of making uPVC windows, and one of most important manufacturing procedures in the whole window manufacturing process. The cutting accuracy (such as accuracy error of cutting length, accuracy error of cutting angle) will affect the welding accuracy and welding strength of uPVC windows, and then affect the size accuracy and angle accuracy of finished uPVC windows. STONE Window Machinery guarantees the cutting quality of the uPVC profile cutting machine through use of high quality hard-alloy saw blades, high accuracy liner bearing motional pairs and headstock, and other high quality machine components, and through our strict quality control system. uPVC profile cutting machines mainly includes double mitre saw, V-notch saw, glazing bead saw, and so on.

2014 LED industry vision
On the global or Chinese market, from technology to application, in the aspect of green energy conservation, the current lighting industry is undergoing a revolutionary renewal period. Incandescent lamps will be eliminated, energy-saving lamps are in full swing, and LEDs are in the ascendant. Policy rationality returns to the market-led development The government introduces subsidy policies, providing enterprises with research and development subsidies can not only promote the progress of new technologies, but also stimulate the market, form mass production, promote the decline of raw material prices, and provide better support for the development of the LED industry. However, this is not the case. As the largest gathering area of ​​the LED industry in the world, in recent years, China's LED industry has developed by leaps and bounds, industrial support has gradually improved, LED technology has been continuously improved, costs have been declining, and product prices have gradually become civilian. However, compared with the international, China's LED industry still has a big gap. The slow development of enterprises is not the government's support and subsidies. On the contrary, due to the excessive subsidies and support of the government, many enterprises have caused government dependence and lost. Participate in the market competition. In the early days of market launch, government subsidies will definitely help to expand the market, and there will be a decisive pull effect on the entire industry chain. However, neither enterprises nor local governments can use subsidies as a mere means. Because companies and products that can receive subsidies only account for a small part, to occupy the market depends on technological innovation, brand and channel construction. The blind development of quick success and instant benefit will only lead to insufficient competitiveness, and it will not be able to escape the bad luck in the market. The huge national financial subsidies have not only brought these enterprises growing up in the greenhouse to a new life, but have become a catalyst for their death. At the same time, the state finances are also unable to withstand the growing number of enterprises that have no benefits as long as they are subsidized. Many people believe that the development of the LED lighting industry is a market economy. If the government policy interferes too much, it will not be beneficial to its development in a benign direction, and will eventually follow the footsteps of the photovoltaic industry. In fact, although the starting point of the local government is good, excessive investment subsidies are the main cause of overcapacity in the industry. The country's huge subsidies have increased the impulse of some enterprises to invest, and the terminal consumption subsidies eventually evolved into direct subsidies to production enterprises. At present, although many local governments still vigorously support the LED industry and introduce relevant policies, since the beginning of the abolition of the LED industry plan in Shenzhen in early 2013, the LED industry policy of the state and many local governments has begun to become rational. After the accumulation of technology in recent years, China's LED industry technology has developed rapidly, and conventional technology is no longer the biggest problem that has plagued the development of LED enterprises. In addition, in recent years, the large-scale ordering of domestic LED equipment has made the number of equipment basically balanced with the demand of the whole market. In 2014, the national policy will be more inclined to subsidize the terminal consumption of products, instead of enterprise technology research and development, equipment. With the introduction and support on the scale of the industry, a policy similar to home appliance subsidies will come. In particular, in the face of the overall downturn in the LED industry, the state may begin to subsidize the new round. The green lighting concept is misunderstood. The current energy consumption accounts for 22% of the global electricity consumption. The significance of green lighting is that it can reduce 80 power consumption from incandescent lamps to energy-saving lamps. After this replacement process is completed, the global lighting energy consumption ratio The corresponding reduction to 17 by the NXP is currently used in the energy-saving lamp chip, which is equivalent to reducing 500 million kilograms of carbon dioxide per year. The future sales are expected to increase by 10 times and 20 times, and the energy saving significance is even more limitless. There is also a lot of misunderstanding about the mercury pollution of energy-saving lamps that the world has criticized. On the one hand, mercury pollution of energy-saving lamps does exist. However, mercury pollution exists in many fields of nature. Relatively speaking, people talk about mercury color change in energy-saving lamps. Energy-saving lamps contain less mercury than a marine fish such as salmon sharks. The gap between LED lighting reality and ideals For the current industry's belief that LED lighting design mainly has heat dissipation, Chen Hao has more added to this. He believes that although there are short-term solutions such as fans and openings, the fundamental direction for solving LED applications is to improve the light efficiency. The same brightness, when the light efficiency is the same, the brightness is relatively increased. Since LEDs are also semiconductors, due to Moore's Law, performance will be greatly improved on a regular basis. When it comes to the market application of LED, some people think that the direction should be intelligent and innovative lighting. Because the original user must first think about the place where the lamp is placed before the decoration, the intelligent lighting allows the user to place the lamp in any position, no matter whether it is spotlight or face light. In addition, another high-end application field of LED is biomolecule, such as high-end chicken raising. In the flower industry, dimming depth dimming is required. However, in addition to incandescent lamps, energy-saving lamps are usually not available. At present, NXP has developed a new LED chip solution that can be adjusted to 1, which is widely praised by the market. It is expected that the LED market share will not be too long from 1 to 20-30, and due to the difference in value, LED cost will be expected to decrease. However, it is difficult to achieve energy-saving lamp cost gradient. How fast LED can go depends on The speed of light improvement of its light source.
