China's Leading Beverage Bottling Equipment Manufacturer
When running a packaging line, efficiency is of utmost importance. Similar to other industries, the paint and coatings industry needs liquid filling machines that correctly fill the finished product into containers and cans. Owing to the viscous nature of paints, liquid fillers, and other specialized packaging machines are required to handle the process.
There are a variety of filling machines for liquid each with its capabilities and advantages. We shall discuss each type of machine below and how it benefits the paint and coatings industry.
1. Pump Fillers
Various filling machines are designed to handle liquids with varying degrees of viscosity. This equipment fills many containers of different sizes and specifications making them a perfect fit for bulk paint and coatings products. Most current liquid filling machines can easily be customized through computers programs with settings for customs fills. This ensures that every container gets the same amount of liquid thus, minimizing product loss.
2. Net Weigh Fillers
Like pump fillers, net weighs fillers can also package paints and coatings in containers with different shapes and sizes. If there is a liquid filling machine that meets the needs of the paints and coatings industry, it’s the net weigh filler. It is designed to handle products of varying viscosities and is perfect for the bulk filling of liquids. For example, it can package paint in 5-gallon pails each with consistent weight and level. Independently timed valves that are operated by a computer help to precisely fill certain amounts of paint by gravity into cans and containers, and will stop once the liquid reaches the required weight.
3. Volumetric Piston Fillers
The paint and coatings industry also needs a liquid filling machine that is great with thick products. Yes, net weighs fillers and pump fillers do an excellent job of packaging thick and viscous products but volumetric piston fillers are better equipped to handle these products. They use customized piston fillers which help to keep the paints and coatings packaging lines consistently efficient by allowing specified amounts and weights to be filled in cans and containers of different shapes and sizes.
4. Other Liquid Packaging Machines
Besides the filling machines, it is essential for paint and coatings industry plants to install other fixtures that keep the packaging process smooth, consistent and efficient. Such equipment includes bottle cleaners, cappers, and labelers. Without a doubt, these machines all play a valuable role in the production process.
So why is a liquid filling machine? A filling machine is designed to increase efficiency and maximize profitability. In the absence of these machines, the filling process becomes slow, and losses are incurred due to inaccurate product fills.
Paints are designed to stick to the surface which makes them so viscous. Indeed, this viscosity makes it necessary to use a liquid filling machine that will resist the clinging nature of paint and efficiently package the end product. Essentially, the use of these machines will help to prevent the build-up of dried paint and other compromises while packaging goods using traditional methods. Also, contamination of paints can have dire consequences. For instance, filling the product into dirty containers can result in the customer having an uneven paint job or a poor finishing as a result of dust. However, a filling machine for liquid is designed to handle such situations by combining various tasks such as bottle cleaning and sanitization.
In addition, paint is chemical in nature. Coming into contact with paint on a frequent basis has its health implications. Additionally, it is very messy and difficult to clean not forgetting that even the paint that is causing the mess is still a loss. That being said, any splashing or spillage; however small or large can have adverse health and financial impacts. Therefore, it is vital to invest in machinery that ensures little or no spillage/splashing. Indeed, a liquid filling machine contributes to a much cleaner workplace, less wastage, a more productive packaging line, and a healthier workforce.
Fortunately, technological advancements have introduced more computerization and automation of the components in liquid filling machines. Consequently, they have become more reliable, and even some current models are fully customizable and user-friendly.
Paint and coatings facilities will, therefore, invest in equipment that is specifically designed for filling various types of paint such as exterior paint, interior paint, paint thinners, lacquer, adhesives, printing ink, cleaning chemicals, and solvents.
During the liquid filling process, there are many other accessories needed too.
1. Bottle Cleaners
Bottle cleaning machines are designed to clean cans and containers by dusting and sanitizing them. Such contaminants lead to spoilage of paints by oxidizing the contents of the product thereby affecting the consistency of the paint or leading to its coating on the inside of the container. Hence, bottle cleaners should be installed in a production line to clean the containers before they finally head to the filling station.
After the containers are filled with paint, they need to be sealed to prevent spillage and contact with contaminants. Capping machines are designed to handle this and can cover various containers and cans of varying shapes and sizes. There are multiple types of capping equipment depending on the kind of caps to be applied. They include automatic vertical wheel cappers, snap/spindle cappers, and chuck cappers. These machines also come with extra accessories such as cap elevators, pre-feeders, and sorters to improve efficiency.
After the cleaning, filling, and capping of the final product, it is important to label it. Labeling machines apply a variety of labels including Mylar, clear and paper labels to cans and containers of different shapes and sizes. They are customizable depending on the customer’s request. For instance, they may apply labels with custom logos, text and images before the paints are finally shipped.
The use of liquid filling machines and other packaging equipment goes a long way in ensuring efficiency and cost-effectiveness. Owing to the nature of paint is a chemical and a thick product, investing in a filling machine not only improves the process of packaging paints and coatings, but it also minimizes health hazards and leads to saving of costs.
There are many varieties of filling machines for liquid in the market. They are designed in different ways, but all achieve the same result. Also, advancements in technology ensure that newer and more efficient machines are replacing older ones. If you are thinking of getting a liquid filling machine or other packaging equipment, but you do not know where to start, it is advisable to talk to a packaging expert who will assist you in determining which type of machine is suitable for your packaging line.
