Water Injection Molding - Cinpres BASF's Engineering Plastics group has invested in water assist injection molding (WAIM) development capabilities in Europe. To produce hollow polymeric parts with complex geometries the Fluid Assisted Injection (FAI) technology is currently used. In this technology water and gas can.

With this process, water is used to core out the hollow sections, then flows through the part to cool the plastic. In fact, studies performed by BASF demonstrate that the temperature of parts molded with gas-assist continues to rise after demolding.

The temperature of WAIM-molded parts drops. In addition, WAIM creates thinner walls that cool faster.

Thinner walls, less material Compared to gas, water has higher viscosity and is incompressible. Conclusions WAIM can be used for production of certain parts eg.

Ducts that are not feasible with GAIM. But the most important task is performance requirements in balancing and process sequences in the process of water injection.

Further investigations and research works are going on at IKV to improve the process. Water-assisted injection molding WAIM is a special molding developed from gas-assisted injection molding GAIM with almost the same ideas, except for the medium water assisted injection molding is water instead of inert gas.

Both GAIM and WAIM provide mechanical strength and dimensional stability for thick molded products, which makes it possible to produce parts with less material without sacrificing quality.
