In the packaging industry, piston fillers are a versatile type of liquid and paste packaging equipment that is commonly used in a wide range of industries, including pharmaceutical, cosmetic, food, and beverage. They work by drawing liquids or pastes into a cylinder, and then using a piston to dispense the product into containers. The piston mechanism allows for precise control over the amount of liquid being dispensed, which is ensuring that each container is consistently filled with the same amount of product.

Choosing the right piston filler can help streamline your packaging operations, improve productivity, increase accuracy, and reduce costs. There are several common mistakes that should be avoided to ensure that you make the right choice. Not sure how to choose the right piston filler for your product? In this post, we'll discuss 11 mistakes to avoid when choosing a piston filler machine for your business.
The viscosity of a product refers to its thickness or resistance to flow. A high viscosity piston filler is designed to handle thick or paste-like products - such as gels, creams, peanut butter, and honey - while a low viscosity piston filler is better suited for liquids such as water or oil. If you have a highly viscous product, look for a machine with a larger piston and possibly a hopper, like this high viscosity tabletop filler. In addition to their standard functionality, some piston fillers are equipped with a heated hopper. This feature is particularly useful when filling highly viscous liquids that can become more manageable when warm, such as melted chocolate, caramel, or honey, into containers. The heated hopper helps to keep the liquid at a consistent temperature, which makes it easier to fill the containers without the liquid solidifying or becoming too thick to handle. Overall, considering the viscosity of your product is an important factor when choosing a piston filler machine, as it can affect the performance and efficiency of the machine as well as the quality of your product.
To ensure a smooth and effective dispensing process for your product, it is crucial to select a machine with a nozzle that caters to your specific needs. This includes considering the size and type of closure on your product's container.
When liquid is dispensed into a bottle, it displaces the air that was previously occupying the space inside. In order to avoid splashing and ensure a smooth flow of liquid, it is important to allow the air within the bottle to escape easily. This can be achieved by selecting a nozzle with an outer diameter that is at least 4-6 mm smaller than the internal diameter of the bottle opening, allowing the air to escape as the liquid takes its place inside the bottle.
Different nozzle types are designed to work with different closure types. Choosing the wrong nozzle can result in leakage, spills, and other dispensing or product-related issues. It is advisable to consult with your packaging equipment provider to ensure that the piston filler you choose has a nozzle that is compatible with the closure type you will be using. This will help you avoid issues with product dispensing, minimize waste, and reduce the risk of contamination.
Piston fillers come in many shapes and sizes. Some machines, like this 50ml Piston Filler, were specifically built to handle only smaller volumes of product. These machines are great for small containers and limited workspaces. Other filling machines, like this one, are meant to handle larger capacities of product in one single motion. The size of your containers is an essential factor to consider when choosing a piston filler. Make sure to choose a machine that is compatible with the size of the containers you'll be filling. If you have containers of varying sizes, look for a machine that has the appropriate capacity and can handle a range of volumes and sizes.
When selecting a piston filler machine, it is crucial to consider the type of filling mechanism that's most suitable for the product you'll be packaging. Products that foam easily, for example, such as soaps or shampoos, require special considerations to avoid spills and overflows. In contrast, chunky products like sauces require a high viscosity mechanism that can handle their consistency without clogging.
For foaming products, consider a machine with a diving or extended nozzle filling mechanism that can reach the bottom of the container and reduce air pockets. Alternatively, a bottom-up filling mechanism can also help minimize foam. Packaging equipment providers often offer machines with customizable options to adapt to different kinds of products. Take the time to assess the needs of your product and choose a piston filler machine with the appropriate filling mechanism to ensure the best results.
When it comes to choosing a piston filler for your business, cost is an important factor to consider. While choosing the cheapest option might seem like a smart move in the short run, it could end up costing you more in the long run.
Low-quality materials, poor construction, and inferior components can all lead to breakdowns, repairs, and replacement costs in the future. In addition, a poorly built machine may not perform as well as a higher-quality machine, resulting in inaccurate fills and other problems that could affect the quality of your product.
Don't sacrifice quality for price. Look for a machine that is well-built, durable, and reliable - even if it costs a bit more upfront. Investing in a high-quality machine will save you money in the long run by reducing the need for repairs and replacements, minimizing downtime, and ensuring consistent, accurate fills that meet your production standards.
Speed is an important factor to consider when selecting your filling equipment. Choosing a piston filler that is too slow can lead to production delays and bottlenecks, which can have a negative impact on your bottom line. On the other hand, selecting a machine that is too fast for your needs can result in wasted resources and higher costs. The machine you choose should be capable of keeping up with the demand on your production line - particularly if it's a high-volume operation.
To ensure that you choose a machine with the right speed for your business, it is important to consider your production needs and the volume of products you need to fill. You should also consider the size and type of containers you'll be filling, as this can affect the speed at which the machine can operate. Single-piston machines are a suitable choice for filling low to medium volumes, but for high-volume production, you might want to consider machines equipped with two, four, or even six pistons. Such machines can effectively handle larger volumes of liquid, improving your overall production efficiency.
Selecting a piston filler that is easy to service and maintain is essential to avoid downtime and minimize production disruptions. It is equally important to choose a reputable manufacturer that offers excellent customer support. This will ensure that any issues or maintenance needs can be quickly and efficiently resolved, minimizing the impact on your business.

From milk to sauce to soup, consumers love the convenience of stand-up pouches for liquid products. CPG companies have responded by increasingly offering their liquid products in this packaging format, many featuring handy pour spouts.
So how do you package a liquid product in a stand-up pouch? With an automatic pouch filling and sealing machine, of course! Today we&#;re taking a step-by-step look at the processes involved in turning an empty preformed pouch into a shelf-ready finished liquid product.
Otherwise known as pouch filling or pouch packing machines, this packaging equipment type fills premade pouches with product and then seals them shut. Pouch fill and seal machines come in two main varieties: Rotary and inline. For the purpose of today&#;s article, we are diving deeper into the more popular rotary layout. This machine design conserves valuable plant floor space and is designed with packaging simplicity top-of-mind.
Rotary pouch packing machines are first loaded with premade bags. There can be one, two, or four bag infeed &#;lanes&#;, with the single lane (simplex) model being the most popular. Upgrading to a model with additional lanes is necessary when throughput needs cannot be met with a single bag infeed.
As the pouches are fed into the packaging machine, they are gripped and held as a rotary table moves counter-clockwise through different static machine 'stations' that are laid out in a circular fashion on the perimeter of the equipment. There are usually between 6 &#; 10 stations on a rotary pouch packing machine, the most popular configuration being 8 stations. Different steps of the pouch filling and sealing process occur at each station.
So let's dive right in! Here's how liquid pouch filling and sealing machines work:
Preformed pouches are first loaded into the bag magazine of the liquid filling and sealing machine. This is a manual process to be completed at regular intervals by an attentive human operator. The pouches are then conveyed to the interior of the machine by a bag feeding roller.
In , Viking developed proprietary robotic infeed technology for pouch fill and seal machines. Basically, a robotic arm uses vacuum suction pads to grasp each pouch and transfers it to the bag grippers. This solution effectively eliminates much of the labor involved in manual bag loading and shingling. Contact us to see this innovative technology in action.
When a pouch is detected in the magazine by a proximity sensor, it is grasped with vacuum suction pads and lifted to a set of bag grippers, which will consistently hold the bag through its entire journey to each station of the pouch packing machine. These grippers can support up to 10 kg (even with high use over time) on the best automatic pouch fill and seal machines.
A note regarding stand-up pouches with pour spouts: Constraints of some liquid pouch packing machines mean your spouted pouch must fall within certain design parameters to be properly gripped by the machine. Ask your packaging equipment manufacturer for details.
If date or lot codes are required on the finished package, this station can be fitted with printing or embossing equipment. Inkjet printers are recommended, but thermal transfer options are available. The embossing option places raised characters into the bag seal area.
At this step, vacuum suction pads grasp the outside of the liquid pouch and gently open the bag. If the pouch is fitted with a zipper, vacuum suction will open the bag and opening jaws catch the top side of the bag to open it. In either case, a blast of clean air is used to ensure the pouch is fully open and ready to be filled.
Sensors are present in the bag area to detect whether a pouch is present. If a pouch is askew or missing, these sensors will communicate that to the filling and sealing stations, which will not engage for that particular pouch. This ensures spilling and product loss are virtually eliminated and also allows the empty pouch to be reused in a future cycle.
A pre-specified dose of the liquid product is now pumped into the pouch by a liquid piston filler that can draw product from a holding tank or hopper. The specifications of the filler are dependent upon the liquid PRODUCT PROPERTIES AND VISCOSITY. In general, liquid pumps can handle anything from water-like products to thick sauces with particulates.
In the case of a solid + liquid product mixture like soup or MREs, this station will dispense the solid product only. A settler will 'shake' the bag to encourage solid components to the bottom of the pouch.
If the product has both liquid and solid components or the bag requires a high volume liquid fill, a second filling station will dispense liquid product.
Prior to liquid pouch sealing, two wire deflator components ensure any extra air is squeezed out of the bag.
To ensure proper pouch closure, two sealing stations are usually required for liquid applications, this being the first. A pair of heat seal bars closes over the sealing area on the top part of the pouch, adhering sealant film layers to one another to create a closed seam.
Alternatively, ultrasonic sealing can be utilized, which uses vibrations to induce molecular friction that generates heat only in the area between film layers. Ultrasonic sealing is more costly than heat sealing but can create a more effective seal for some liquid packaging applications. Your pouch packing machine manufacturer can guide you to the best sealing option for your particular needs.
Identical to the previous step, the second heat sealing station reinforces the seal, ensuring a completely closed package seam. A second station is not required for ultrasonic sealing.
To strengthen and flatten the seam, a cooling bar now passes over the sealed portion of the pouch. This cooling bar can also add serrations to the seam if desired. The finished liquid pouch is now discharged onto a conveyor and can be held in a receptacle or transported downline to ancillary equipment like case or carton packers.
