With the rapid development of science and technology, the use of plastics in modern medicine is steadily increasing. Medical devices made from injection-molded plastics help reduce health care costs, infectious diseases and pain management. High-tech polymers are used in medical device prototyping and are often used to create improved prosthetics and devices to reduce the risk of infection. Medical plastic injection molding directly improves patient safety and the ability to save more lives. High-gloss injection molding: the basic process of high-gloss injection molding is to rapidly heat the surface of the mold with high temperature and high pressure steam before injection molding, so that the surface temperature of the molding mold cavity reaches above the glass transfer temperature (TG) of the resin plastic, and then inject the plasticized plastic melt into the closed mold cavity. During the injection phase, the mold temperature is kept constant by high temperature and high pressure steam. After injection molding, stop the air supply, blow out the steam in the tube with the air pressure of the duct, and then inject cooling water to make the mold temperature drop rapidly, until the mold is cooled and opened to take out the product.

This offshore drilling platform was named Zhongyouhai No. 5. The jack-up rig was started on August 31, 2006 and was completed in one year. The platform has a total length of 75 meters and a total width of nearly 50 meters. The designed working depth is 4.5 meters to 40 meters. The maximum drilling depth is 7000 meters. The platform can drill 20 wells without moving in the same place. The designed service life is 20 years. The 70DB drilling rig produced by Baoji Petroleum Machinery Co., Ltd., which is selected by the platform drilling rig, is the most advanced ultra-deep AC variable frequency digital controlled drilling rig developed by China. The platform has the ability of drilling, cementing and auxiliary oil testing. The platform has good production and living guarantee facilities. The oil, fresh water and food that the platform last replenished can maintain the staff's life for 20 days.
According to experts, earlier this year, CNOOC introduced designs from abroad and produced similar platforms. The self-elevating drilling platform completed by China Petroleum Offshore Engineering Co., Ltd., from process design to construction and construction, was independently completed by China and has reached the international advanced level.
In recent years, the pace of offshore oil exploration and development in China has been accelerating, and there is an urgent need for offshore oil engineering to provide a strong guarantee. Since its establishment in 2004, China National Petroleum and Ocean Engineering Co., Ltd. has insisted on increasing its reserves and production in China's oil offshore oilfields, and is committed to building equipment. Since the beginning of this year, 10 new platforms have been approved, of which 7 are under construction and 3 have been completed and put into production. According to relevant personnel, Zhongyouhai 5 will be towed into the Bohai Bay area in recent days to ease the pressure on the shortage of offshore exploration and development drilling platforms.
Completion of self-elevating drilling platform independently developed by China
China's self-elevating drilling platform has been rewritten in Qingdao since its history of importing - on September 3, the first self-elevating drilling platform designed and built by gear racks was completed in Qingdao Beihai Shipbuilding Heavy Industry Co., Ltd. Delivered and used, China National Petroleum Corporation has its own intellectual property rights.
