Stone won the provincial scientific and technological achievements into a special fund ultra-million

December 16, 2022

Recently, I learned from the Provincial Science and Technology Department: Jiangsu Jinshi Machinery Group Co., Ltd. "High-pressure oil and gas wellhead equipment and automatic safety control system research and industrialization" project was approved as the 2005 provincial scientific and technological achievements into a special fund project. The project requires a total investment of 1 to 2 billion yuan, of which the provincial government subsidies 10 million yuan free of subsidies, loan interest 234 million yuan, totaling 12.34 million yuan, is the largest industrialization in Jinhu County, the government subsidies up to science and technology research and development projects.
Jinshi Group has five patented technologies, such as flat-plate valve, slip-type casing hanger, tubing head cable sealing device, hydraulically actuated safety valve and stem metal self-sealing device. The high-pressure wellhead equipment and automatic safety control technology can automatically release the pressure of the safety valve control line when the pressure in the wellhead is abnormal or the fire in the wellsite occurs, so that the well head closes automatically. The technology is in a leading position in the world.

Stereo Light Curing Molding - Sla

STEREO LIGHT CURING MOLDING - SLA
It mainly uses photosensitive resin as a raw material, and utilizes the characteristic that liquid photosensitive resin will cure quickly under ultraviolet laser beam irradiation. The photosensitive resin is generally liquid, and it immediately initiates a polymerization reaction and completes curing when irradiated with a certain wavelength of ultraviolet light (250 nm to 400 nm). SLA focuses on the surface of the light-curing material by focusing ultraviolet light of a specific wavelength and intensity to solidify it sequentially from point to line and from line to surface, thereby completing the drawing of a layered cross-section.
