How Hot Embossing Works

Hot embossing is a sophisticated manufacturing technique that mechanically displaces thermoplastic polymers by pressing a structured mold into a heated polymer substrate. As the polymer softens under heat, the microscale features of the mold are imprinted into the surface, creating intricate channels and structures vital for microfluidic applications.

Technical Advantages

Hot embossing excels in manufacturing micro components, offering a cost-effective and timely solution. This technique outperforms alternatives like micromilling by producing smaller, smoother microstructures in polymer substrates, ideal for medium-volume production.
