Manufacturing of foundation sheets / beeswax processing

How Are Our Beeswax Foundation Sheets Produced?

Beeswax foundation sheets play a crucial role in beekeeping, as they provide bees with a stable base on which they can build their comb. But how are these foundation sheets actually made? Here is an overview of the different production methods and which ones we use:

1. Rolling (Manual and Automated)

The rolling process is one of the most traditional and commonly used methods for producing beeswax foundation sheets. The procedure is as follows:

- Wax cleaning: First, the beeswax is thoroughly cleaned and freed from impurities.
- Melting and cooling: The cleaned wax is then melted and poured into large, flat sheets.
- Rolling: These sheets pass through two rotating rollers that imprint a precise honeycomb pattern into the wax. This determines the desired thickness and structure of the foundation sheets.
- Cutting: Finally, the foundation sheets are cut to the required size.

Advantage: The rolling process creates particularly stable foundation sheets.

Disadvantage: The honeycomb cells can become slightly elongated during the rolling process and may therefore not always be perfectly symmetrical.

2. Roll-Casting

Roll-casting combines the advantages of casting and rolling and represents a more modern method of producing foundation sheets:

- Cleaning and melting: As with rolling, the wax is cleaned and melted.
- Casting: The liquid wax flows between two rotating rollers, where the honeycomb pattern is formed. The process is water-cooled, which allows the wax to solidify more quickly.
- Cutting: The embossed wax sheet is then automatically cut to the desired height and length.

Advantage: Roll-casting enables extremely precise production of foundation sheets with nearly perfect honeycomb cells (99.9% accuracy).

Disadvantage: At low temperatures, the foundation sheets can become brittle.

3. Casting

Pure casting is another traditional method, but it is less commonly used for large production volumes because it is more labor-intensive:

- Cleaning and melting: The beeswax is cleaned and melted.
- Casting: The liquid wax is poured into special molds that contain the honeycomb pattern. These molds are usually operated manually.
- Solidifying: The wax cools and hardens inside the molds. After solidifying, the finished foundation sheets are removed.

Advantage: This method requires less specialized equipment, making it suitable for smaller beekeeping operations or hobby beekeepers.

Disadvantage: The precision of the foundation sheets may vary, and the production process is slower than other methods.

Our Production Methods at Zschopautaler Imker

At Zschopautaler Imker, we use state-of-the-art technology and apply the roll-casting method on two machines.

The production process always begins with the careful cleaning of the beeswax. Since summer 2024, we are also certified organic. This allows us to offer this service to our organic beekeeping customers as well.

The cleaned wax is disinfected at 140°C to eliminate any potential pathogens such as American foulbrood or Nosemosis (Nosema). After filtration through filter paper, the wax enters our machines, which can hold up to 120 kg of liquid wax. At about 80°C, the wax then flows between two rotating rollers that form the hexagonal honeycomb pattern. For each cell size (4.9 mm, 5.0 mm, 5.1 mm, and 5.4 mm), we use special roller assemblies. These are made from zinc or aluminum and are cooled with a special biodegradable water-based release agent, with a concentration of only 0.1%.

Finally, the continuous sheet of wax is cut to the desired size. Rotary knives ensure precise height, and a guillotine-style knife cuts the length. This results in a wax sheet that is millimeter-precise in height and cut in 5 mm increments in width.

The entire production process is strictly monitored to ensure that our foundation sheets meet the highest quality standards. Our organic certification guarantees that our production is not only of high quality but also sustainable and environmentally friendly.

Our foundation sheets provide bees with a stable base while helping them conserve energy, as they need to do less work when building their comb. The result is healthier bees and more efficient honey production — a win for beekeepers and nature alike.

How Does the Beeswax Reach Us?

Very simple. You can drop off your wax personally at our address: Kopernikusstraße 2, 09669 Frankenberg — or send it as a parcel to our address, including a note with your contact details, desired cell size, and sheet size. We take care of the rest and contact you once everything is ready. Processing time is typically 2–4 weeks, depending on workload.

What Happens to Your Wax?

Your wax is stored in special containers labeled with your name and address until processing, to avoid any mix-ups. During cleaning, some loss occurs due to impurities, water, and machine operation. After production, a remaining amount of approx. 1.5–4 kg usually remains; of course, you will receive this back. You only pay for the produced amount of foundation sheets. The packaged foundation sheets are also labeled with your name or customer number. Once everything is finished and paid for, you can collect your foundation sheets, or we can send them back to you by parcel.

Organic Certification

Our beeswax and foundation sheet production is officially certified organic. Certification is carried out by ÖkoP Zertifizierungs GmbH — a state-approved control body with the control number DE-ÖKO-037.

As part of the inspection and certification process, ÖkoP checks all areas of our production — from processing to packaging and storage. ÖkoP ensures that all processes comply with the requirements of the current EU Organic Regulation 2018/848.

Thanks to this independent inspection, we can offer beeswax and foundation sheets that are produced, processed, and labeled according to strict ecological standards. Transparency, traceability, and quality are as important to us as they are to the organic certification — so you can use our products with confidence.
