A tablet press in operation An old rotary tablet press. A tablet press is a mechanical device that compresses powder into tablets of uniform size and weight. A tablet press can be used to manufacture tablets of a wide variety of materials, including pharmaceuticals, nutraceuticals, cleaning products, industrial pellets and cosmetics.
For compression testing, the analyst generally aligns the tablet in a repeatable way, [2] and the tablet is squeezed between a fixed and a moving jaw. The first machines continually applied force with a spring and screw thread until the tablet started to break. [3] When the tablet fractured, the hardness was read with a sliding scale. [3]
The compression is done either by a single-punch machine (also called stamping press, achieves an output of approximately 200 tablets per minute, making it ideal for manufacturing small batches of tablets) or by a multi-station machine (rotary press). The tablet press is a high-speed mechanical device.
A First Article Inspection (FAI) is a production validation process for verifying that a new or modified production process produces conforming parts that meet the manufacturing specification detailed in technical or engineering drawings. Typically, a supplier performs the FAI and the purchaser reviews the report.
Process validation is the analysis of data gathered throughout the design and manufacturing of a product in order to confirm that the process can reliably output products of a determined standard. Regulatory authorities like EMA and FDA have published guidelines relating to process validation. [ 1 ]
Process validation involves a series of activities taking place over the lifecycle of the product and process.". [4] A properly designed system will provide a high degree of assurance that every step, process, and change has been properly evaluated before its implementation. Testing a sample of a final product is not considered sufficient ...
Continued process verification (CPV) is the collection and analysis of end-to-end production components and processes data to ensure product outputs are within predetermined quality limits. In 2011 the Food and Drug Administration published a report [ 1 ] outlining best practices regarding business process validation in the pharmaceutical ...
The process involves the application of heat, pressure and agitation to mix materials together and 'extrude' them through a die. Twin-screw high shear extruders blend materials and simultaneously break up particles. The resulting particles can be blended and compressed into tablets or filled into capsules. [11]
