There are many methods of plastic molding. Injection molding is one of them. Injection molding is also called injection molding, which is called injection molding for short. It is a main molding method of thermoplastic. Because it has the advantages of wide application, short forming cycle, high production efficiency, good production conditions, easy mechanization and automation, it plays an important role in the whole plastic forming process.Injection molding refers to injecting granular or powdery plastic from the hopper of the injection machine into the high-temperature barrel, heating, melting and plasticizing to make it a flowing melt, and then under the high pressure of the plunger or screw of the injection machine, it passes through the nozzle at a large flow rate and is injected into the mold cavity. After a period of pressure maintaining, cooling and shaping, When the mold is opened, the Plastic Parts with certain shape and size can be detached from the mold cavity. In this way, the time required to complete an injection cycle can range from a few seconds to tens of seconds, which mainly depends on the size and thickness of the workpiece.

According to LEDinside, a green energy business unit of TrendForce, a global market research organization, China's LED packaging companies are still growing rapidly in 2013. For example, Ruifeng Optoelectronics, a representative manufacturer of large and medium-sized LED backlight packages, has revenue in the first half of 2013. It was RMB 294 million, a year-on-year increase of 67. Among them, the medium and large-size backlight LED revenue was RMB 135 million, a year-on-year increase of 113. The newly added small and medium-sized backlight LED business revenue exceeded RMB 10 million.
In addition, China's small-size LED backlight package representative Jufei Optoelectronics' first-half net profit in the first half of 2013 increased by 25~55 compared with the same period of last year. LEDinside said that with the continuous improvement of China's packaging technology, China's LED packaging industry has shown a rising momentum in the backlight field. Driven by the shipment of Chinese TV brands, the performance of LED backlight package manufacturers represented by Ruifeng, Jufei, Zhaochi and Dongshan Precision has increased significantly.
Although China's LED backlight packaging factory still has a large gap between its capacity and revenue scale and Taiwan's packaging plants, it has gradually entered the backlight field. Ruifeng Optoelectronics' total revenue for the whole year of 2012 was RMB 500 million, up 72 from the previous year, of which LED backlight components revenue was 290 million, with an annual growth of 169. Jufei Optoelectronics LED backlight components revenue of 420 million, annual growth rate of 37 .Zhaochi shares, Dongshan Precision LED mainly produces LED backlight components and modules, and their performance has doubled.
LEDinside pointed out that although the overall level of LED backlight packaging technology of Chinese manufacturers still has a certain distance from Taiwan or international manufacturers, it has gradually been recognized by Chinese downstream enterprises, especially for small-sized backlights used in smart phones, and the high cost performance is affected by China. Second-line or even first-line mobile phone manufacturers are favored.
In addition, in the large-size LED backlight field, China's TV manufacturers began to use China's domestic large-size backlight LED components in the second quarter of 2012. Among the six TV manufacturers in China, except for Hisense, China-made LEDs have not been adopted on a large scale. Other manufacturers All have been introduced into China's packaging factory LED backlight components, and the application ratio has gradually expanded.
LEDinside, a backlighting LED or module supplier in China's major TV manufacturers, said that backlighting is still the largest application area of ​​LEDs. The global LED backlight packaging manufacturers are mainly concentrated in Taiwan, Japan and South Korea. Due to the high threshold of LED backlight packaging technology, Chinese manufacturers are more difficult to intervene, especially in the large-size backlight field. Only a few Chinese packaging manufacturers have the ability to produce. In recent years, the gap between China and Taiwan and international manufacturers has been narrowing. The manufacturing cost advantage has led to the continuous improvement of the cost performance of LED backlight components in China, which has gradually replaced the market share of international manufacturers such as Taiwan or Japan and South Korea.
Although the LED backlight market demand is close to saturation and the new market is limited, there are still alternative opportunities for Chinese LED backlight package manufacturers. LEDinside pointed out that the overall revenue of Chinese manufacturers is far less than that of Taiwanese manufacturers. In addition, Japanese and Korean manufacturers still have more room for alternative markets. Therefore, Chinese LED packaging manufacturers have also indicated that they want to enter the LED backlight field or expand production capacity.
LEDinside emphasizes that mainland China is the world's major production and accumulation area for TV, mobile phones, notebooks and other products in the future. It is the main consumption base for LED backlight components. In the future, China's LED backlight packaging manufacturers will replace Taiwan or international manufacturers will be an irreversible trend. For manufacturers such as Japan and South Korea, there will still be a certain market under the protection of patents; for Taiwan LED backlight packaging manufacturers, the upstream and land factories have the same resources, but the downstream lacks the brand estuary. If they still do not make changes, Will be in a passive situation.
