At Kawamura Kikai Co., Ltd. – Composite Division, we focus on the development and processing of advanced thermoplastic composite materials.

【CFRTP Molding Methods】
The two primary molding methods for CFRTP are hot press and cold press.
Hot Press: A method in which the die is heated during forming. It accommodates a wide range of intermediate materials and makes it easier to achieve high surface quality.
Cold Press: A method in which the material is preheated in a separate process and then formed in a cooled die. It offers shorter cycle times and is suitable for deeper shapes.
It is important to select the appropriate method depending on product appearance requirements, geometry, and takt time.

【Fundamentals of Press Forming and the Importance of Thermal Control】
Press forming is a processing method in which pressure is applied to deform a material into a specified shape. In composite molding, however, temperature control is critically important.
For thermoplastic composites, controlling flexibility during heating and solidification during cooling greatly affects product precision and mass production capability.

【Characteristics of Hot Press Molding】
Hot press molding is performed with heated dies. By heating the material, the resin melts and forms an integrated structure that bonds tightly with the reinforcing fibers.

Main features:
Suitable for molding prepreg and nonwoven materials
Capable of forming complex shapes such as foamed structures and variable wall thickness designs
Our facility enables heating control above 400°C, supporting high-performance resins such as PEEK

【Composite Molding Equipment】
Kawamura Kikai Co.,Ltd. is equipped with specialized facilities to support both hot press and cold press molding:
200-ton hot press machine (maximum die size: 1200 × 1500 mm)
Heaters compatible with PEEK
Heat & cool temperature control unit (exceeding 400°C)

【Hot Press Molding Process (Shown in the Video)】
The video demonstrates the hot press molding process:
The material is placed on the lower die, and the upper die descends.
After several minutes of cooling, the upper die rises.
The finished product can be touched immediately by hand.
Visitors are welcome to observe this process in person at the company’s head office.
