Composite preforming : Hot drape forming machines (HDF)
While hydraulic presses and turnkey production lines represent PINETTE PEI’s core business, it should be stressed that in order to control the entire production process, we also design and supply preforming machines such as hot-draping machines (HDF) for the production of composite preforms.
Hot drape forming Machine - HDF
PINETTE PEI supplies thermoforming machines for prepregs and dry carbon fabric sheets. Our equipment can be adapted to operate in class 8 cleanrooms, thanks to dust, airflow and temperature management devices.

The infrared structure has a 1,200 mm stroke, enabling the distance between the infrared and the preforming tools to be adjusted. The mobile transfer table is equipped with an electric motor, castors, a speed inductor and 10 thermocouples.
The entire system is driven by an automated control system via a Programmable Logic Controller (PLC), which controls and regulates the heating temperature. To facilitate the work of operators, the control panel is displayed on a touch-sensitive HMI (Human Machine Interface) screen.
As an engineering group, PINETTE PEI is also able to design and build customized equipment, specifically tailored to your preforming applications.
