CFRTP is attracting attention as a next-generation material combining lightweight properties and high strength. Its thermoplastic moldability and carbon-fiber stiffness enable applications in automotive, medical, robotics, and sports equipment.

At the same time, CFRTP molded parts increasingly require post-processing such as machining, drilling, tapping, and assembly, demanding high precision and stable quality in each process.

【Why Integrated Processing of CFRTP Products Is Required】
Because CFRTP’s machining characteristics vary significantly depending on fiber orientation and resin type, improper cutting, drilling, or tapping can negatively affect dimensional accuracy and surface quality.
In addition, outsourcing each process to different suppliers increases the risk of defects due to variations in material handling and processing history. For these reasons, an integrated system that covers molding, secondary processing, and assembly provides a significant advantage in both product development and mass production.

【Advantages of an Integrated System】
Kawamura Kikai Co., Ltd. provides end-to-end processing for CFRTP products, covering molding, machining, drilling, tapping, assembly, and inspection. This integrated approach offers:
・Improved quality control through process traceability
・Reduced lead time and cost by eliminating inter-process inefficiencies
・Rapid prototyping from a single drawing, enabling faster initial validation

【Available Processing Capabilities】
The company supports the following processes:
・Machining: contour cutting, rib trimming, edge finishing, deburring
・Drilling: single-hole and multi-hole drilling, high-precision positioning
・Tapping: thread machining for M2–M10 sizes
・Trimming: removal of excess material and precision contour cutting
・Assembly: component assembly, fixture-based alignment, and electrical/fit inspection

【Equipment and Production Capability】
All processes are completed in-house, supported by machining equipment and inspection tools such as CMMs, profile projectors, calipers, and micrometers, ensuring stable quality from processing to inspection.

【Quality Control and Traceability】
Dimensional inspection is conducted through 100% or sampling measurement. CMM verification of geometry and hole positions, combined with ISO 9001:2015–compliant record management, ensures consistent quality in mass production. For prototypes, measurement data and improvement proposals are provided to support efficient specification alignment with customers.

【Strength of One-Stop Manufacturing】
Leveraging 70 years of metal processing expertise, Kawamura Kikai provides integrated CFRTP solutions from molding to machining and assembly. This approach enables weight reduction and design flexibility beyond conventional metal processing while balancing lead time, cost, and quality.

The company supports both mass-production development and low-volume, short-lead-time prototyping, offering material selection, design optimization, and mold design support from the early development stage.

【Summary】
Secondary processing of CFRTP products requires specialized know-how and equipment that account for the material’s unique characteristics. An integrated system covering machining, drilling, tapping, and assembly significantly impacts both development speed and product quality.

Kawamura Kikai Co., Ltd. supports high-precision, short-lead-time manufacturing across a wide range of materials and geometries. If you are facing challenges in post-processing CFRTP products, please feel free to contact us.
