schema thermoformagePlastic thermoforming (also called vacuum forming) is one of the forming techniques used in industry for the production of plastic parts such as yogurt pots, packaging, cups…

The technique is quite simple. It consists in taking a material in a sheet form, the heat through electrical resistance to soften it and place it in a mold to give it its final shape obtained during the cooling phase.

Thermoforming process for manufacturing plastic products

As you can see from the picture, the outside air pressure will allow the plate to take the shape of the mold before cooling the plastic.

The principle has not changed a lot in the past decades but now we can transform most thermoplastic materials: polystyrene, polypropylene, polyethylene, polycarbonate, polyvinyl chloride…

This process allows the creation of storage pieces but it is also used in particular sectors such as: food packaging market, health market, household appliances, the car industry.
