Can You Use Liquid Filling Machines for Waxy or Molten Products?

Products such as candles and deodorant are not things we often think of as liquids. But the truth is, they start out as molten liquids before cooling to a solid. When thinking about how these materials are packaged, you may be surprised to learn that they are produced using liquid filling machines that are specifically meant for molten products.

Molten liquid filling machines can offer benefits to many different industries, including the automotive industry, health and beauty, home improvement, and more. There are a few different types of machines that are often used with molten liquids, though, that you should consider adding to your inline packaging system for optimal efficiency when packaging molten or waxy products.

Filling packages with liquids is generally done using liquid filling machines ; however, not every product is made in the same manner. For example, things like sauces or detergents will have different requirements than products that need to be packaged while they are molten—for instance, wax for candles. E-PAK Machinery offers a portable molten filler to simplify the process of doing such work, and our machine has the capability to fill a wide range of products, with a variety of shapes and sizes of containers. But does your business need one? Find out whether simple liquid filling machines will do, or if a portable filler might be better.

What Are Portable Molten Fillers Best For?

Portable molten fillers have the capability to be used for a range of products that need to be put into their packaging while still hot – products such as deodorants, glycerin soap, petroleum jelly, and lip balm, to name a few. If your packaging space doesn’t allow for a permanent machine, a portable filler may be in the cards for you—E-PAK machinery’s molten filler can hold up to 40 gallons of pre-melted natural wax in the insulated holding tank, set to the precise temperature necessary by the operator. Portable fillers are great for products that blend a mixture of dye and fragrance, as the dye and fragrance mixture is not blended in the tank but rather in the wand. This means that the operator can change to a new dye and fragrance quickly and easily, with minimal waste. For instance, scented candles are a product that is manufactured using a molten filler.

Should You Use a Portable Molten Product Filler?

If your business needs a way to fill molten products into their containers, but your workspace doesn’t have a lot of floor space left to install a permanent machine, this portable machine is ideal. It takes up minimal room, and is mounted on soft rubber casters for portability that’s safe for all types of flooring. Additionally, it has a self-contained heating system, is easy to operate, and features quick-set controls and precise heating controls, making it an ideal option for those products that need to be molten when filled into their package.

Cooling Conveyors

After your molten product is filled, one of the key components to a quality product is allowing it to come to room temperature gradually and smoothly. A cooling conveyor is exactly what your production line needs to transport containers slowly from their filling stations to their next destination in a matter that promotes gradual temperature change.

Specifically, our cooling conveyors come in a variety of belt lengths and widths to meet your line's specific needs. We also offer some additional and optional features on our cooling conveyors, such as:

• Cooling fans
• Brackets
• Belts for different containers/products

Pre-Heat and Re-Melt Stations

It's not enough to have a quality molten filler for your products; for maximum quality and a beautiful appearance, you should also have pre-heat and re-melt stations on your line that can be utilized both before and after the filling process.

Specifically, the pre-heat station offered by E-PAK is great for heating your containers prior to filling them; this helps to give them a more consistent appearance after the fill. The re-melt station is used at the end of the cooling process to help achieve and smooth and flawless appearance that'll your customers will appreciate.

When working with molten products, having the right tools and components for the job is a must.
