History of Compression Machines

Rotary Compression machines used nowadays in pharmaceutical industries play an important role in the compression of tablets. The rotary compression machine has an ancient history and took many modifications.

First Machine

Stroke manufactured the first commercial rotary compression machine in the USA. Stroke’s first developed rotary compression machine brought a revolution in the field of tablet compression in pharmaceutical industries. The first rotary machine of stroke was B1 and soon it became very popular in all pharmaceutical industries.

Later on, stroke manufactured a heavy machine to compress large-size tablets and the machine was named D3.D3 was built with large punches and dies and its popularity was increased within days. From that time B and D became international standards.

Later on, stroke moved to England and he started to manufacture machines in England. He trained the staff and established there manufacturing units. During world war two stroke left England and after his departure, the trained staff in England start manufacturing machines for his country with the name called Manesty.

Soon Manesty machines became as popular as stroke machines and Manesty tooling was not changeable with stroke machines. Manesty named its small machines B3B and large machines D3a.

In the start of 1900 unique model of Kilian was developed in Italy by Kilian Gmbh. The Kilian machine was different from B and D standards. In Kilian compression machine the traditional punch head system which guides the upper punch was not used instead it has it’s on punch shape in which punch is guided by cam angle on side of upper punch barrel.

In 1997 unique model was developed by” Ima called ima comprise ” using a unique feeding system based on centrifugal forces created by the rotation of the turret. In Ima machine tablet ejection system was also unique, the tablet is ejected from the bottom of the die cavity using the force of gravity.

In 2005 fette developed most advance high-speed machines with the concept of segmented dies. Segmented dies reduce set up hours.
