The invention relates to an improved method of cold forming a shaped foam article from a foam having a vertical compressive balance equal to or greater than 0.4 and one or more pressing surface and articles thereof. The improvement comprises the use of a stamping press to form the shaped foam article. Preferably, the stamping press is operated by mechanical or hydraulic means. The shaped foam article may be shaped on one or more surfaces.
摘要:
The invention relates to an improved method of cold forming a shaped foam article having a shape with a high degree of draft with improved surface aesthetics, specifically reduced surface cracking and articles made therefrom. The improvement is using a mold with a reduced-slip cavity surface, preferably a textured cavity surface.

摘要:
The invention relates to an improved method of cold forming a double-sided shaped foam article wherein the improvement is using a double-sided foam blank cut from a foam plank having a vertical compressive balance equal to or greater than 0.4 to produce the double-sided shaped foam article. The double-sided foam blank has a first pressing surface and a second pressing surface wherein the difference in compressive strength between the first and second pressing surfaces is equal to or less than 200 percent, most preferably, the compressive strength of the first pressing surface is the same as the compressive strength of the second pressing surface.
摘要:
The invention relates to an improved method of extracting a shaped foam article from a mold cavity after being formed, specifically by imparting a vacuum sufficient enough to hold the shaped foam article to one side of the mold, preferably the core half of the mold, when the mold opens.
