The Ultimate Guide to Automatic Piston Fillers

Improve your packaging solutions. With the right machine, you can provide better protection, reduce instances of leaks, and ensure you’re your products get to customers safe and sound. Start by investing in excellent filling machines. If you’re shopping around for piston fillers, here are some of the things you’ll need to know.

Piston Filler: What is It?

It’s a filling machine that is designed to handle a variety of products with different viscosities. Consider whether you are handling liquid that won’t change viscosity even after exposed to changing temperatures. Piston fillers are ideal for handling sauces and honey along with other products with high viscosity levels. Some products with particulates are also a good match.

Main Parts of a Piston Filler

A better understanding of what a piston filler is and how it works will help you choose the best machine for your needs. To start, there are five main parts of the machine. This includes the hopper, valve, cylinder, piston, and nozzle.

Learn About Volume Capacity

The length of stroke and the inside diameter of the cylinder determines the product volume that the machine can handle. If you want the machine to be able to handle more product volume, find options that come with bigger cylinders.

Adjustable Volume

Many piston fillers come with a handwheel that you can use to adjust the volume of the product. Test the setting and figure out which stroke length works perfectly for your project.

Adjustable Speed

The product volume isn’t the only thing that you can adjust. You can also lower or increase the speed of the piston’s movements. Slowing it down a notch or so could be one way to prevent errors. You could also try speeding it up. Depending on the product you’re handling, changes in the piston’s speed could help improve packaging efficiency.

Container Size

The size of the container that you’ll use also impacts the kind of machine you need. Automatic piston fillers are well able to get products from a bulk source like a tank. That means you’ll want to find a hopper that’s a good size for that.

Changing Parts

If you handle products of different liquid types and sizes, then it’s smart to pick a machine that can accommodate different pistons and cylinders. You can swap the parts, depending on the needs of your project. That way, you won’t have to buy more than one machine. You can use the same one for a range of products.
