<p>A process and apparatus (200) for embossing thermoplastic products having precise microstructured surfaces including using a continuous press (200) having upper and lower belts (210 & 260) with the embossing pattern (s); feeding thermoplastic material through the press (200) where heat and pressure are applied to form the embossed pressure microstucture, and cooling the embossed material, all while maintaining pressure. A continuous embossing tool (200) is provided by welding segments together. The welds including interface material at the weld joint which is of a different material than the segment material to increase the tensile strength.</p> |
