Water-assisted injection molding technology is an advanced injection molding process that injects part of the melt into the mold cavity, then injects high-pressure water into the melt through equipment to finally shape the workpiece.
Advantages:
Due to the incompressibility of water, the front end of the water forms a solid interface, squeezing the inner wall of the product into a cavity. The front end of the water also plays a role in rapid cooling. Therefore, water-assisted has many advantages that gas-assisted cannot match. Research and application show that water-assisted can generate thinner and more uniform cavity walls, and the inner wall surface of the flow channel is very smooth. Especially for thick-walled workpieces, the cooling time of water-assisted can be greatly reduced compared with gas-assisted.
