Types of wax filling machines

There are different types of machines for filling hot wax on top of the candles. The primary purpose remains the same; all of them help to fill the wax into the candle mold with precision and accuracy. The following types of wax filling machines are used in the industrial and commercial candle-making processes.

• Liquid Wax Filler: A liquid wax filler is a top-fill machine for candles. It has a built-in heating element that keeps the wax in a liquid form. The filler uses gravity to fill liquid wax in a container or candle mold from the top. The filler is lightweight and easy to use. However, it has its limitations because it does not control the amount of wax filled in the candle mold.
• Manual Control Button Wax Filling Machine: This type of wax filling machine uses a manual control button. It has a transparent tank with a level indicator. An adjustable feeding pump supplies the liquid wax to the nozzle. The nozzle can be changed depending on how the customer wants to fill the liquid wax. Using the button on the control box, the operator can start and stop the flow of the liquid wax. It is a versatile machine that can be used to fill any kind of liquid in a container.
• Semiautomatic Candle Filling Machine: Operators can use this machine to fill up to 1,000 candles at a time. The pump helps to fill liquid wax within 100-500 ml. Operators use the control panel to press a button to fill the wax. When filling the container, the nozzle can be adjusted to the desired level. The machine is made from stainless steel and has a drip-free filling system.
• Automatic Candle Filling Machine: The fully automated filling machine is more advanced than the semiautomatic candle-filling machine. This machine has a benchtop, a large capacity tank, and a feed pump and can fill up to 5,000 containers or candles. The machine has an adjustable fill counter, preset filling amount, and control pump. It can fill liquid wax from 1000 ml to 5000 ml. It is a more expensive option, but it is excellent to use if there is a high volume of wax required in the production process.

Specifications and Maintenance

Every specification in a wax filling machine plays an important role in determining its performance. Here are some key specifications alongside their maintenance requirements:

• Container Size

  The container size of the filling machine determines how much liquid wax it can hold and supply during the filling process. Small container sizes like 1L or 2L are easy to clean and refill. For example, with a 1L container size, operators can simply drain the residual wax, clean the container, and refill it with fresh wax.

• Heating Mechanism

  Filling machines use different methods to heat wax, such as boiling water, heating plates, or hot air. Regardless of the method, the heating components should be kept free from residue to allow uniform heating. For instance, if a heating plate is used, operators should ensure that the surface of the plate is clean before starting to heat the container.

• Nozzle Size

  The size of the nozzle determines the amount of liquid wax dispensed and the speed at which it is filled. Nozzle sizes are usually measured in millimeters (mm) and vary based on the purpose of the machine. Different nozzle sizes can be changed to adjust the flow rate. When cleaning the filling machine, users should focus on properly cleaning the nozzles. This prevents any clogs and ensures a smooth application.

• Filling Accuracy

  To maintain the desired level of precision, the maintenance of the filling machine should be done regularly. While different types of wax filling machines have different mechanisms, the general rule is to inspect and calibrate any parts that may disrupt accuracy. This is especially important for the machines that use pumps to dispense the liquid wax.

• Pneumatic Pressure

  A lot of wax filling machines use compressed air to control the pressure that dispenses liquid wax. This means the machine will need to be maintained regularly to ensure the air pressure system is working properly. The air hoses shouldn’t have any leaks, and compressor valves should function appropriately with no clogs. Regular maintenance helps to uphold air pressure control and consistent filling.

Industry applications of wax filling machines

Industries and factories with large-scale candle production use these machines to fill the candle jars and molds with any hot liquid wax. They all benefit from feeding the finished candles into an air-cooled conveyor system of easy cleaning.

Craft breweries use the wax filling machine in bottle waxing to achieve a non-slip grip on the bottle and to preserve the freshness and carbonation of the beer inside. The machine helps brew customers uncap a beer that is both fresh and safe. The bottleneck is sealed with a colorful layer of wax.

Custom candle makers can bring this type of machine to their bespoke candle-making process. The machine fills the process with efficiency and uniformity when filling jars and containers with wax.

Home fragrance product manufacturers use it to speed up the filling process in Candle Manufacturing. The machine can number in the hundreds or thousands of candles and be used to fill small, medium, and large vessels in containers...

Robotics companies may include this as part of an automated system for customers who want more than just a simple machine to fill their containers with a particular liquid.

These machines can also be used in Candles for Extinguishing Smoke and Candle Pillar Filling. Filling out the bottom side of a candle helps to support the structure of the candle. If the candle has a wick on it that will need to be trimmed each time the candle is burned, this bottom fill may also prevent smoke from being extinguished because part of the core will be in the bottom of the candle.

How to Choose a Wax Filling Machine

When choosing a wax filling machine for purchase, several things need to be considered. To begin with, it is essential to know the type of machine required. Businesses should decide whether they require manual, semi-automatic, or fully automatic wax filling machines before purchasing. This decision will be influenced by factors like production volume, workforce availability, and desired automation level.

Also, investigate the machine’s capacity and speed. When buying a wax filling machine, it is important to select a model with a capacity and speed that suits the intended production volume. Such models will guarantee efficiency and timely delivery.

It is also important to consider the machine’s compatibility with wax types. Since different waxes have specific properties and formulations, it is important to ensure that the selected machine is compatible with the particular type of wax that will be used.

Another important consideration is the machine's precision and accuracy. Choose a filling machine that is accurate and offers high precision. Such a machine will ensure consistent and precise wax placement, minimizing waste and enhancing product quality.

Consider the machine's ease of use and cleaning features. A machine and its components that can be cleaned, dismantled, and operated with ease will ensure a quick and effective production process.

When shopping for a wax filling machine, it is wise to determine the safety and compliance with the selected machine's regulations. Check the safety features of the filling machine, such as emergency stops, safety guards, and operator safety guidelines. Ensure the machine complies with relevant industry regulations and standards to minimize risks and avoid legal complications.
