System Module Overview
The system is organized into three functional modules. This modular architecture allows researchers to tailor the system to a wide range of coating and impregnation applications, providing flexibility, process control, and efficient use of materials in R&D environments.
Pre-Die Extension Line
This section prepares the substrate prior to coating or impregnation and includes:
- Unwinding unit for controlled material feed
- Pigtail unit for fiber guidance and alignment
- Spreader unit to ensure uniform material distribution
Die Modules
The central processing unit consists of a guide wheel and an interchangeable die, allowing the system to be configured for different applications. Available die options include:
Post-Die Extension Line
After processing, the material is stabilized and collected through:
- Air-cooling unit for controlled solidification
- Transport godet for precise material handling
- Winding unit for consistent product collection
- Laser micrometer for continuous diameter check.

Tow Impregnation Die
The Xplore Tow Impregnation Die is designed to impregnate multifilament fiber bundles with molten polymeric material. It utilizes spreader bars to separate the fiber bundle, ensuring uniform polymer penetration between individual filaments and preventing inconsistencies in the impregnation process.
A key challenge in coating multifilament fiber bundles is achieving uniform wetting of each individual filament with molten polymer. Incomplete impregnation can lead to inconsistent material properties and localized stress concentrations, ultimately reducing the mechanical performance and durability of the final composite.
The Xplore Tow Impregnation Die is specifically designed to address this challenge. Within the die, the fiber bundle is actively spread, allowing the molten polymer to penetrate between individual filaments and ensure thorough wetting of each strand. This controlled impregnation process promotes uniform material distribution and improves the structural integrity of the resulting composite.
The die features interchangeable inner sleeves that can be tailored to different fiber bundle diameters. This adaptability allows precise control over the amount of polymer applied, enabling optimal impregnation across a wide range of fiber types and bundle sizes.
For enhanced process control, the die includes a threaded port for a pressure transducer, enabling real-time monitoring and adjustment of processing pressure. This capability allows researchers to fine-tune impregnation conditions, ensuring consistent coating quality and reproducible results.
Together, these features provide a highly controlled and flexible impregnation process, supporting the development of advanced composite materials with improved performance and reliability.
