With thermoforming presses, fibre-reinforced plastics can be formed in a defined temperature range and maintain the desired shape after cooling. Langzauner Perfect utilises these specific properties for thermoforming presses, in order to manufacture three-dimensional moulded parts from high-performance plastics by applying heat and pressure (possibly assisted by compressed air or vacuum).
What has developed from the handicraft process of “deep-drawing” is a production process on an industrial scale today – and the trend is increasing. Langzauner presses convince by innovation, efficiency and reliability in a variety of different thermoforming processes. This technology from Upper Austria ensures the cost-effective, high-precision production of moulded parts of fibre-reinforced plastics.
Examples of thermoforming presses from LZ Perfect
- NFPP (natural fibre with polypropylenes) in the one-shot procedure or as hybrid in combination with back-moulded reinforcing ribs
- Bilaminates and trilaminates for processing components for automotive interiors in a continuous process with a heating step in a calibration press or a convection oven and subsequent shaping in the press mould.
At Langzauner, every thermoforming press is designed and implemented along the customer process.
Reinforced plastics: High-performance material for lightweight construction
High-performance plastics – composite
| PEEK | High temperature-resistant polyether ether ketone |
| PAEK | High-strength polyaryl ether ketones |
| PFA | Meltable and extrudable perfluoroalkoxy |
| PEI | Polyetherimide |
Short cycle times are fundamental
The processing of composite materials (carbon fibre, glass fibre, natural fibre, thermoplastic) requires short cycle times to bring the preheated material into the press to be shaped. Automated solutions from Langzauner ensure that you won’t lose any valuable time.
Step 1: Consolidation
In the first step, the organo sheet is consolidated, in order to reliably remove possible moisture from the layer structure. Skilled tempering is performed in the press via heating plates and a high-precision cooling cycle. Langzauner Perfect offers electrical heating plates as well as water cooling or the use of thermal oil. The end of the process provides the semi-finished product in the form of an organo sheet.
Step 2: Forming
