Background: Different laboratorium and production scale machine design inside the cosmetics manufacturer is a common practice. It has been challenging when bringing manual laboratorium into the automatic production machine setting during the up scaling process. Pressure and force are important parameters that must be determined. At the same pressure, product can accept different force, and resulting different quality using a different machine design. It requires a long time to find tuning the production scale machines.
Pressure and force measurement are quite complex as each machine design has multi factors that influence it. Compression Load cell is used to converts a pressure into an electrical signal in the form of force that can be measured and standardized. The physics formula, P=F/A is used to predict the correlation of pressure and force values in each machine.
This purpose of this study was to find setting conversion between pressure and force using an experimental validation. This study would be a guidance for R&D and Engineer in up scaling process, moreover it could be used for decreasing waste of setting time.
Methods: Measurement of pressure and force were carried out on a Semi Manual Hydraulic pressing machine (A) and a Powder Press Automatic 7 Serie 2A Kemwall machine (B). Both machines were calibrated using standardized measuring instruments. Fixed and variable factors were determined in this study. Fixed factor includes punch surface area (cm2). Variables factors include pressure (PSI), force (kgF), and pressing time (second).
Compression Load Cell Apparatus was used to obtain correlation of pressure and force values from each machine. Furthermore, an experimental validation was conducted on powder foundation formulation X using machine A setting; pressure in 1000 PSI with pressing time in 2 times 5 seconds. The product quality is proven through a series of tests including hardness test, drop test, rub test, sensorial test, and consumer application test.
Results: From the measurement results, the force value on machine A obtained was 2200 kgF, while on machine B the pressure needed to obtain the same force value was 900 PSI. Correlation of the two machine design is obtained by making a standard series of pressure to force using a compression load cell and predicted by physics formula P=F/A.
Discussion and Conclusion: Based on the confines and conditions of this study, correlation data from machines with different design can be a guideline for R&D and production to decrease waste of setting time to acquire the same product quality. Further research is needed on the factors that affect the pressing mechanism in each machine.
