The batch of eight-axis intelligent thermoplastic tape placement and winding integrated machines is an all-in-one intelligent forming equipment developed for continuous fiber-reinforced PEEK, PPS, and other high-performance thermoplastic materials. It is core-equipped with in-situ laser consolidation forming technology, capable of tape placement and winding, achieving single-process one-step forming. This is a core frontier technology for high-end thermoplastic composite manufacturing.

1. Principle of In-Situ Laser Consolidation Forming Technology

The machine integrates four core units: a high-precision laser heating system, a constant-tension feeding mechanism, a CNC placement and winding motion system, and a constant-pressure compaction roller. During the forming process, the unidirectional prepreg tape is fed at a constant speed to the placement/winding contact point. The laser precisely focuses on the prepreg layup interface, heating the PEEK resin to its melting temperature within milliseconds. Simultaneously, a precision press roller applies constant pressure to fully melt the resin at the interface between the new layer and the underlying component. The entire process of heating, melting, compaction, and consolidation is completed at the same instant of placement or winding, eliminating the need for subsequent autoclave or oven post-processing. The tape is consolidated immediately upon placement, forming a complete component in one step.

2. Core Technological Advantages of the Process

Significantly Enhanced Interlayer Bond Strength
Laser spot uniform temperature control precisely matches the CF/PEEK processing temperature range, ensuring thorough interface melting. The component’s resistance to delamination, fatigue, and interlaminar shear strength are significantly superior to traditional step-forming processes, meeting stringent mechanical testing standards for aerospace and medical devices.

No Secondary Heat Treatment, Shortened Production Cycle
Eliminates the entire sequence of layup preforming, loading into an autoclave, high-temperature holding, and cooling. Production efficiency for single tubes and curved components is improved by over 60%, substantially reducing energy consumption and labor costs. Suitable for both high-volume mass production and low-volume custom development.

High Forming Precision, Strong Product Stability
Equipped with a multi-axis CNC linkage system that provides real-time closed-loop control of laser power, tape feed speed, fiber tension, and compaction pressure. Placement angle and wall thickness are uniformly controllable, with extremely low dimensional variation in finished parts. Large components are free from deformation and internal stress defects.

Compatible with Junhua HPP’s Full Range of Thermoplastic Prepregs
Perfectly compatible with the company’s self-developed carbon fiber and basalt fiber reinforced PEEK unidirectional prepreg tapes. It can flexibly switch between placement and circumferential winding composite paths, processing various component geometries such as cylindrical shells, curved skins, and irregular support structures.

Green and Intelligent Integrated Production
Full digital parameter recording with traceable process data. Eliminates the need for large autoclave equipment, resulting in a smaller footprint and lower energy consumption, enabling intelligent, green manufacturing of lightweight components.

3. Integrated Machine Capabilities

The equipment integrates dual modes of automated tape placement and continuous winding. It can switch between unidirectional layup and circumferential winding composite forming based on product structure, accommodating the production of flat panels, rotating shells, and complex curved irregular parts. It truly achieves integrated placement, winding, and laser consolidation, with a single machine covering the trial production and mass production of multiple categories of high-end thermoplastic products.
