Water-assisted injection molding: Water-assisted injection molding technology is an advanced injection molding process in which part of the melt is injected into the mold cavity and high-pressure water is injected into the melt through the equipment to finally shape the workpiece.
Due to the incompressibility of water, the water front creates a solid interface, squeezing the inner wall of the product into a cavity, and the water front also acts as a rapid cooling. Therefore, the water supplement has many advantages over the gas supplement. Research and application show that the water supplement can produce thinner and more uniform cavity wall, and the inner surface of the flow channel is very smooth. Especially for thick wall workpiece, the cooling time can be greatly reduced compared with gas auxiliary.

This year is not only the Chinese market, but the overseas LED lighting market is also very popular. The domestic sales and exports of LED lighting have shown rapid growth. However, the market is still mixed.
According to data from the High-Tech LED Industry Research Institute (GLII), China's LED lighting exports in 2013 exceeded US$5.4 billion. In the first quarter of 2014, China's LED lighting exports reached 1.376 billion US dollars, an increase of 63.7. In April 2014, China's LED lighting exports reached 867 million US dollars, a record high.
In 2014, China's LED lighting exports will exceed 8 billion US dollars, an increase of 48. Dr. Zhang Xiaofei, president of Gaogong LED Industry Research Institute, in an interview with China Business News, expects that LED lighting sources and lamps will reach 1.85 billion in 2014. Only, the growth of 71.3, the market size increased by 48, which means that prices continue to decline.
In the face of the outbreak of LED lighting market, how to build a healthy LED industry ecological environment is particularly urgent.
According to GLII statistics, in overseas markets, China's LED lighting products recalled more than 70 brands, including 44 unknown brands, most of which are related to electromagnetic compatibility. Zhang Xiaofei called for China's LED lighting industry to be self-disciplined, to avoid damaging the overall image of Chinese brands and affecting overseas LED lighting orders.
High gloss injection molding: Highlights the basic process of injection molding is prior to injection molding, through the use of high temperature and high pressure steam will mould surface rapidly warming, the forming die cavity surface temperature of resin plastic glass transition temperature (Tg) above, then the plasticizing good plastic melt into the closed mold cavity, the injection stage, mold temperature by high temperature and high pressure steam remains the same, When the injection is finished, the air supply is stopped, and the water vapor in the pipe is blown clean by air pressure of the air pipe. After that, the cooling water is injected to make the mold temperature drop rapidly until the mold is cooled and the product is removed by opening the mold
