ARTICLE WITH DIFFERENT TEXTURED SURFACES

A method of blow molding an article having at least one layer of thermoplastic material. The method comprises the steps of heating a mold having an inner surface with two or more areas of different surface textures to a first temperature of greater than 55 C. and subsequently feeding a parison into the mold. The parison is then blown against the inner surface of the mold to form an article. The temperature of the mold is subsequently lowered to a second temperature of between 20 C. to about 55 C. and the temperature cycle time (t.sub.ct) of the mold is less than 250 seconds. Using the two phase heating and cooling process in combination with a mold featuring different surface textures provides a finished article with different visual effects.
