PULTRUSION LINES FROM LANGZAUNER PERFECT

Pultrusion lines from Langzauner Perfect are raising fully automated large-scale production of composite parts in the automotive and aviation industry to a new level. Our customers can look forward to bespoke plants that are geared 100 percent to the desired profile characteristics and processes.

PULTRUSION PROFILES: RAPID PRODUCTION IN LIGHTWEIGHT CONSTRUCTION

The production of thermoplastic profiles is gaining in importance in the automotive and aviation sector. The pultrusion of lightweight profiles offers stable precision in rapid production processes.
Langzauner pultrusion lines represent state-of-the-art technology in the field of pultrusion:

Semi-finished products: Pre-impregnated continuous filaments or injection/resin bath
Temperature and feed control infinitely variable
Profile feed without interruption (consistent quality)
Saw and packaging material change with zero cycle time impact
Control and visualisation of the process chain
Component traceability

TAILOR-MADE SOLUTIONS FROM ONE SINGLE SOURCE

We are using our entire expertise from the field of pultrusion line construction to design bespoke plants. From the impregnation of the continuous filaments with resin as an upstream process or via injection/resin bath, including the continuously adaptable temperature and feed control to the overall process control system – everything from one single source – made in Lambrechten (Upper Austria).

Your benefits:

One contact partner for a turnkey production line.
One control and visualisation for the entire process chain and data recording.
Customised order processing as well as component traceability within the production processes. Every component is provided with an ID number and is monitored within the whole process control system.

FULLY AUTOMATED PRODUCTION OF THERMOPLASTIC PROFILES WITH PULTRUSION LINES

Extensive expertise and cutting-edge technical solutions allow you to optimally integrate every Langzauner plant into the user-specific environment.

Thanks to the perfect linking of the individual plant parts, our plants offer maximum flexibility combined with user-friendliness. The pultrusion line not only detects and records all material states in a fully automated fashion during the entire process, it can also automatically respond to any deviations. The infinitely variable heating and speed parameters also makes it possible at all times to run in, test and optimise new semi-finished product combinations for the continuous production of thermoplastic profiles.

Description

Pultrusion: the process in detail

The fully automated pultrusion line serves to produce thermoplastic profiles in a continuous process.

This process involves loading pre-impregnated, continuous fibre-reinforced semi-finished products in the tension-controlled unwinder. The individual semi-finished strands are bundled in the preheating tunnel and heated uniformly from all sides. In the subsequent tool, the locking mechanism, they are then merged into one profile under pressure and temperature. After having passed through the cooing line and the haul-off unit that allows for infinitely variable speed control, the cured profiles are cut off by a flying saw.

After they have been cut, the finished profiles are fed out via a delivery table. In order to enable a change of the packaging cartons with zero cycle time impact, the delivery table can outfeed the profiles on two sides. In this way, interruption of the profile feed set and resulting losses in quality are prevented. The design allows for fully automated continuous operation, even without a plant operator having to be present.
