How does plastic food container vanumn forming machine work?

Plastic food containers are an essential part of our everyday lives. They allow us to pack ready-made meals for easy transport to another location. But have you ever wondered how these containers are made? The answer lies in plastic food container thermoforming machines! In this blog post, Honggang Machinery will take a deep dive into how this fascinating technology works, which is responsible for the production of millions of plastic food containers every day.

The sheet feeding and stretching parts of the plastic food container thermoforming machine provided by Honggang are driven by servo motors. Wide range of applications, suitable for most customer requirements. PLC programming, manual interface operation, stable operation, low noise and high efficiency.

Working principle of plastic food container thermoforming machine

The working principle of plastic food container thermoforming machine involves several steps. First, the plastic sheet is fed into the machine, where it is softened to a pliable state by heating elements.

Next, a vacuum is applied to remove any air between the mold and the sheet. The upper mold blows air, and the lower mold sucks air, so that the softened plastic sheet forms a shape that conforms to the mold.

Once formed, excess material around the edge of the container is trimmed using a cutting station and transported to suction cups, which hold the product off the raw material onto a feed table, while excess waste continues to be rolled up for recycling.

The entire process takes just a few seconds to produce hundreds of containers per minute with high precision and accuracy.

Thermoforming machines have revolutionized food packaging production by providing an efficient and cost-effective way to produce high-quality plastic containers that meet industry standards for hygiene, durability and safety.
