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.

Recently, DESMI Ocean Guard A/S will provide ballast water treatment systems for Maersk Line's seven new container ships ordered by COSCO Shipyard in Zhoushan.
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
DESMI wins orders for ballast water treatment systems for 7 new container ships
DESMI Ocean Guard A/S announced that its RayClean ballast water treatment system has been phased in and will be installed on a series of new container ships being built for Maersk Line by Zhoushan COSCO Shipyard. Under the contract, the company will equip each of the seven container ships with two RayClean 500 ballast water treatment systems, in addition to two alternative ships.
It is reported that these ballast water treatment systems will be delivered in 2016 and 2017.
