Casting slush-molding

PVC plastisols are suspensions of PVC resin in a hquid phase mainly constituted by the plasticizer and the stabilizer. Plastisols can be processed by different techniques, such as rotational casting, slush molding, dip molding, dip coating, or spray coating. In these pro-... 

Plastisols and organosols - PVC powders are dissolved in solvent (organosol) or dispersed in plasticizer (plastisol), and fillers are added in conventional slow speed mixers. The resultant viscous liqtrids arc used to rotationally cast, slush mold or dip articles. Mineral fillers arc used to increase stifihess and hardness, reduce tackiness and reduce costs, although they may increase viscosity and reduce shelf life.

Slush casting, also called slush molding or cast molding, is extensively used. It is a method where TPs in a liquid form are poured into a hot mold that is stationary or moving where a viscous skin forms. The excess slush is drained off, the mold is cooled, and the molding stripped out. Used to produce rain or snow boats, auto instrument panels, over shoes, corrugated and non-corrugated complex tubes, caps, etc. 

Slush molding is used mainly with plastisols. It is usually a continuous operation. The mold (female) is filled above a specific pattern mark and passed through an oven that sets or gels the material in contact with the metal mold surface. These molds are electroformed copper or cast aluminum. The material in the center of the mold that is still a fluid is poured out of the mold with the mold returning to an oven for final fusion. Upon removal from the fusion oven, the mold is cooled and the finished product is stripped from the mold. Vacuum or compressed air can be used with large parts or with those of a complex geometry to assist in product removal. One part of the mold must be open to the atmosphere to permit pouring and product removal.

Slush molding is a mnq>le variation of the casting process. The low-viscosity material, such as, plastisol is poured into a hot mold and after a thick casting is formed on the wall of the mold cavity, the excess material is poured out. In order to ensure uniform coating, the mold is often rotated. 

By virtue to its contribution to low viscosity and good viscosity stability, Palatinol N is suitcible for plastisols including spray coating, dipping, casting, or slush molding. 

In-mold coated (IMC) cast skins that combine the formation of a slush molded (or PU spray skin) with subsequent PU-RIM molding in the same mold to form the substrate layers. 

Plastisols allow the use of inexpensive manufacturing techniques, such as slush and rotational molding, casting, dipping, etc. They are employed for tile manufacture of a large variety of parts, e.g., toys, floor mats, handles and many others.
