The SD1 machine, developed by Josef Wick in the 1970s, revolutionized the sealing of aluminum tubes and quickly found application in the pharmaceutical, cosmetics, and food industries. With its precise technology and durable construction, it remains an indispensable tool for sealing small batches of aluminum tubes in pharmacies, laboratories, and small production units.

The SD1 is an example of the engineering skills of the late 1960s, which still proves its effectiveness and relevance decades later.
