Paper forming machine starting by roll DPF series

A "paper tray forming machine" is a type of machine (in this case the model studied is called DPF), with a patented process, used to produce trays or containers starting from paper in layers. These trays can be used for a variety of purposes, such as food packaging, egg containers, electronic products, industrial items and more.

The forming process for these paper trays usually involves the following steps:

1.Paper feed: A multi-layer paper roll or sheet is fed into the machine.

2.Heating and forming: The paper is heated and molded into the desired shape using a mold that matches the size and shape of the trays you want to produce with male and female methodology.

3. Pressing: The paper is pressed into the shape of the mold to ensure it retains its final shape.

4.Cooling and drying: The formed paper is cooled and dried to ensure its stability and strength directly in the forming press.

5. Cutting and finishing: The formed trays are cut and finished according to the specific requests.

6.Stacking of the parts on the conveyor at the end of the line.

Paper trays formed with these machines are often considered an ecological and sustainable solution for packaging, as paper is a biodegradable and recyclable material. These machines have a wide application in the food industry and other industries that require eco-friendly packaging solutions.

In particular, DPT (Dry Paper Technology) "dry paper forming" refers to the process of making paper with the use of a minimum of water in the paper sheet forming process. It is a modern patented method.

The dry paper forming process starts from multi-layer rolls. However, unlike the wet method, where the pulp is mixed in large quantities of water and then drained and pressed to form the sheet, in dry paper forming, the small amount of water is removed into a hot mold during material compression.
Dry paper forming offers advantages such as a more energy efficient process compared to traditional PULP production (only about 15 kW of consumption in an automatic DPF 35 model machine) and faster (indicatively 6 to 8 seconds for cycle). Additionally, the finished product is known for its smoothness, and uniform texture.
