【Composite Product Development and the Use of CFRTP】
In the development of composite products, close coordination is required across all stages—structural design, material selection, molding technology, post-processing, evaluation, and mass production. Among available materials, CFRTP (Carbon Fiber Reinforced Thermoplastic) offers a high degree of flexibility in material composition and molding methods. To achieve optimal product performance, technical support from the early design stage is essential.

Kawamura Kikai Co., Ltd. provides a comprehensive support system that allows consultation from a single drawing and delivers consistent assistance throughout the entire product launch process.

【Initial Design Stage: Optimization of Structure and Materials】
In CFRTP product design, fiber orientation, rib layout, and wall thickness significantly influence performance. The company provides the following technical support:
・Structural design proposals considering fiber orientation
・Material selection support (nonwoven fabrics, prepregs, semi-pregs, etc.)
・Resin selection tailored to application needs (PA6, PEEK, PLA, etc.)
・Pre-design verification through CAE analysis (handled as needed, including external partners)

This enables rational structural designs that balance mass productivity and functional performance.

【Prototyping Stage: Short Lead Time and Molding Expertise】
After finalizing the design, molding trials are conducted to proceed to prototyping. Dedicated equipment ensures rapid turnaround.
・200t hot press machine (up to 1200×1500mm molds)
・High-precision temperature control via heat & cool systems
・Integrated molding up to 500×500mm
・Proven molding performance for CFRTP prepregs up to 2–3mm thickness

Environmentally friendly materials such as PLA and PA11 are also supported, enabling application-specific prototyping.

【Evaluation and Improvement: Verification and Feedback】
After prototyping, dimensional accuracy, appearance, and strength are evaluated. Design and mold improvements are implemented as necessary.
・Dimensional evaluation using 3D measuring instruments and profile projectors
・Strength testing and repeat molding evaluations
・Feedback on molding defects and mold adjustments
The short feedback cycle reduces overall development lead time.

【Transition to Mass Production: Equipment Capacity and Quality Assurance】
In the mass production phase, stable supply and quality control are critical. The company offers:
・More than 50 press machines ranging from 10t to 500t
・Quality assurance system based on ISO9001:2015 certification
・Centralized management of inspection records and traceability through proprietary systems
Stable quality and supply are ensured from small-lot to medium-scale production.

【Advantages of Integrated Support】
Handling everything from prototyping to mass production within one company provides several benefits:
・In-house management from material procurement to mold fabrication, molding, and inspection
・Reduced risk of delivery delays and faster information sharing
・Sustainable manufacturing using recycled materials and offcuts

Development support is available even at the conceptual stage before product specifications are fully defined.

【Summary】
Developing CFRTP products requires specialized expertise and responsiveness across all stages—from structural design to prototyping and mass production. Leveraging extensive experience in metal processing and composite molding, Kawamura Kikai Co., Ltd. supports product development through a fully integrated system.
For companies facing challenges in design, prototyping, or mass production, the company serves as an optimal development partner.
