Thermoplastics at Langzauner – Your Complete Solution for Fiber-Reinforced Components

From consolidation to the finished functional component – Langzauner offers everything from a single source for the efficient processing of fiber-reinforced thermoplastics.

With decades of experience in composites projects, we deliver one-stop-shop solutions for international clients who expect custom, turnkey solutions.

Many Processes. One Goal: Flawless Thermoplastic Components with No Compromises

The finishing and shaping of fiber-reinforced thermoplastics is complex, and many production lines remain fragmented: separate suppliers handle tape, consolidation, molding, and post-processing. Common consequences include a lack of process integration, interface losses, quality variation, and increased lead times.

Langzauner closes this gap with integrated solutions, optimized for:

  • Precision & Efficiency

in industries with high demands on quality and fast throughput for thermoplastic component manufacturing.

Our Solution: A Complete Thermoplastics Process Chain

Langzauner offers the full value chain – from engineering through automation:

Technology & Process Modules in Detail

Langzauner brings together all relevant technologies to manufacture complex thermoplastic components in a comprehensive process:

Consolidation

  • Batch: hot / cold pressing of tape stacks
  • Aim: low porosity, defined crystallinity, reproducible properties

Forming (Stampforming)

  • Preheating via IR, contact or convection
  • Transfer into temperature-controlled tooling
  • Cycle times < 60 s
  • Applications: structural parts, crash elements, underbody covers

Hybrid Molding (Overmolding / Bolt-On)

  • Press = closing module, laterally coupled injection unit
  • Materials: ABS, PC, PA, PEEK, etc.
  • Injection pressure > 1,900 bar, volumes > 1,600 cm³

LFT-D (Long Fiber Thermoplastic – Direct)

  • Direct integration of long fibers > 10 mm
  • Very high energy absorption, short cycle times
  • Scalable from lab to high-volume production

Heating Methods for Thermoplastics

Depending on the application and process requirements, Langzauner offers different heating technologies:

Heating MethodPrincipleAdvantagesConstraintsTypical Applications
Infrared (IR)Radiation energy → absorption by the matrixVery fast heating; non-contact; flexible, zone controllablePossible uneven heating; surface overheatingStampforming, Hybrid Molding (automotive)
Convection (Hot Air)Hot airflow over materialVery uniform temperature; gentle for thick laminatesSlower heating; higher energy usePreheating preforms, batch consolidation
Contact HeatingDirect contact with heated plates / jawsVery efficient; homogeneous core; precise controlSurface impressions possible; limited to flatter geometriesConsolidation of tapes / laminates, heated jaws
Induction / DielectricInduction: eddy currents (for carbon) / Dielectric: molecular rotation (HF / microwave)Very fast volumetric heating; locally controllable; suitable for in-situMaterial dependent; homogeneity challenging; high capital costAFP, aerospace specialty processes, rapid preheating of organosheets

Each method has strengths and limitations — we choose the optimal solution with you, based on material, geometry, and production volume.

Typical Applications & Industries

  • Automotive: front ends, battery housing, underbody covers, crash structures
  • Aerospace: lightweight structural parts, components using welded vs riveted joints
  • Industrial & Construction: pallets, machine housings, panels, formwork
  • Specialty Segments: high-performance plastics, bespoke solutions

Frequently asked questions about thermoplastic processes:

Sensor technology, process monitoring, and digital data acquisition are fully integrated. This ensures parameters are documented, quality is assured, and processes are reproducible.
The systems are scalable and can be designed for different quantities – from small series to fully automated production lines.
From the initial idea to the series production, Langzauner accompanies the entire process – from engineering and tool design to press construction and automation, commissioning and process optimization.
The component thickness depends on the material and process. Thanks to precise heating and cooling technology and press forces of up to 10,000 kN, both thin-walled and solid thermoplastic components can be produced.
Langzauner processes a wide range of fiber-reinforced thermoplastics, including common matrix systems such as ABS, PC, PA, or PEEK – in combination with glass, carbon, or other high-performance fibers.
