How Liquid Filling Machines Benefit the Paint and Coatings Industry
Using Filling Machines to Increase Efficiency and Profitability
Liquid fillers are integral to liquid packaging lines, with automated models capable of maximizing efficiency. Without this equipment, the filling process wouldn’t be reliable enough to ensure that no product loss occurs because of inaccurate fill levels.
Technological developments that are creating more automation and computerizing many of the components in filling machines have made them more dependable than ever before, with many of the best models designed to allow for full customization and user friendliness.
One type of liquid filler that can meet the needs of the paint and coatings industry is the net weigh filling machine. Designed to handle products of low to high viscosity, net weigh fillers are ideal for filling liquids in bulk quantities, such as 5-gallon pails, with consistent weight levels for each container.
Net weigh fillers work by using independently timed valves with custom programming through the filler’s computer. They can then fill precise amounts of liquid by gravity into containers, stopping once the liquid reaches the specified weight.
These fillers can fill many different types and sizes of containers, with many of the top models capable of lasting for many years.
What is a Piston Filling Machine?
At Liquid Packaging Solutions, there are a number of different types of filling machines manufactured to handle different product viscosities, different fill sizes and other variations in packaging projects. The piston filling machine can solve many issues for products with particulates or high viscosity liquids, though it can also handle thin and medium viscosity products as well.
As product sits in the hopper, the valve, which sits between the hopper and the nozzle, will be open from the hopper to the cylinder. The piston will begin to withdraw from the cylinder, typically after an operator activates the fill by stepping on a foot switch. As the piston withdraws, product from the hopper will fill the empty cylinder. Once the piston has withdrawn to the desired point, the valve will rotate to allow product to move through the nozzle. At this point the piston push back in to the cylinder and move product through the nozzle and in to the waiting bottles or other containers. This process creates a highly accurate volumetric fill as the interior volume of the cylinder will never change, meaning the volume of product released to the bottles will never change.
