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.

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 Method | Principle | Advantages | Constraints | Typical Applications |
|---|---|---|---|---|
| Infrared (IR) | Radiation energy → absorption by the matrix | Very fast heating; non-contact; flexible, zone controllable | Possible uneven heating; surface overheating | Stampforming, Hybrid Molding (automotive) |
| Convection (Hot Air) | Hot airflow over material | Very uniform temperature; gentle for thick laminates | Slower heating; higher energy use | Preheating preforms, batch consolidation |
| Contact Heating | Direct contact with heated plates / jaws | Very efficient; homogeneous core; precise control | Surface impressions possible; limited to flatter geometries | Consolidation of tapes / laminates, heated jaws |
| Induction / Dielectric | Induction: eddy currents (for carbon) / Dielectric: molecular rotation (HF / microwave) | Very fast volumetric heating; locally controllable; suitable for in-situ | Material dependent; homogeneity challenging; high capital cost | AFP, 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.
