A new fabrication process for micro structures from thermoplastic polymers is presented. Two layers of thermoplastic polymer are placed onto a tool with micro structures. By a friction welding machine, the polymer surfaces are rubbed against each other generating friction heat and melting the polymer. The polymer adapts to the surface shape of the micro structures on the tool. Then, the movement of the machine stops and the polymer cools down and hardens in the shape of the micro structures. The entire process is finished within a few seconds and the required investment costs are in the range of some 10,000 € to approximately 200,000 €. Compared to ultrasonic hot embossing, samples with larger overall dimensions can be fabricated and the heat distribution has been proven to be more homogeneous.

提出了一种由热塑性聚合物制备微结构的新工艺。将两层热塑性聚合物放在具有微结构的工具上。通过摩擦焊接机，聚合物表面彼此摩擦，产生摩擦热并使聚合物熔融。聚合物适应工具上微结构的表面形状。然后，机器的运动停止，聚合物冷却并硬化成微结构的形状。整个过程将在几秒钟内完成，所需的投资成本大约为10,000欧元到大约200,000欧元。与超声热压花相比，可以制造更大尺寸的样品，并且热分布更加均匀。
