Filling Machine for the Cosmetic Industry
Many cosmetic products require a positive displacement type filling machine that can volumetrically fill relatively viscous products. Because these viscous products flow quite slowly, they must be forced through a fluid path under some pressure to deliver them into the container. Examples of these products are liquid soaps, shampoos, conditioners, lotions and creams. A piston filling machine accomplishes this perfectly with large fluid paths that lend themselves to moving thick products like the above.
One problem that has occurred in the cosmetic industry with increasing frequency is the fact that the number of products a producer must offer is increasing while the batch sizes of these products is decreasing. This puts an additional burden on the cosmetic producer with more frequent changeovers and cleanups. While a Piston Filling Machine is excellent for handling these types of products, its weakness is that it does not clean up easily and requires adjustment in the setup process to dial in the correct fill sizes after each changeover. Thus, a piston filler can be at a disadvantage to some cosmetic companies with many Stock Keeping Units (SKU's) in their product line. On the other hand, a Servo Pump Filling Machine is almost ideally suited to the cosmetic industry because it not only handles a wide range of product viscosities but also cleans up and changes over very quickly. See below for more details on the Servo Pump Filling Machine.
