Carbon fiber reinforced plastics (CFRP and CFRTP) are composite materials that are high in strength, resistant to rust, and excel in heat resistance and conductivity. However, due to their high strength, they are also difficult to process and are considered hard-to-machine materials. Additionally, the procurement of carbon fiber materials is challenging, and the production process tends to have low productivity, making these materials very expensive. At our company, Yamada Manufacturing Co., Ltd., we have accumulated processing achievements in CFRP and CFRTP and possess extensive know-how. Therefore, we are capable of performing trim and press processing aimed at reducing manufacturing costs. This document, "Technical Data: Material Properties and Processing Know-How of CFRP and CFRTP (Thermosetting and Thermoplastic Resins)," summarizes these insights and experiences from our perspective in an easy-to-understand manner!

• Composite Materials

Our company, Yamada Manufacturing Co., Ltd., has built a long-standing trust and track record with our customers in the field of non-metallic resin pressing due to the uniqueness of this area. We will introduce basic information and know-how regarding the processing of insulating materials from a perspective that only we can provide. Please read this before selecting materials or processing. We will present know-how for bending insulating materials using "thermal bending processing." This method involves applying high heat to the material or mold to soften the material before applying pressure, a technique not commonly seen in the bending of metal materials. The reason is that when bending metal, heat is generated due to the pressure applied. Since insulating materials like paper and resin do not reach high temperatures, it is necessary to apply heat through a different principle. [Features] ■ When you want to bend at a large angle (around 90°) or when the material is prone to spring back, applying heat can effectively maintain the angle. ■ Thermoplastic resins become less prone to cracking when heat is applied. ■ It is possible to "condition the material and maintain its shape" by applying heat after bending. *For more details, please refer to the PDF document or feel free to contact us.

We will introduce basic information and know-how related to insulating material processing from a perspective that only we can provide. Please read this before selecting materials or processing. We will present know-how for bending insulating materials using "score line (crease) processing." This processing method involves creating a crease using a score line blade, approximately halfway through the thickness of the material from the surface. By performing score line processing, subsequent bending becomes easier, and it becomes more feasible to achieve a wide range of bending angles, even when a large angle is required. [Features] ■ Reduced springback after bending ■ Easier to maintain bending angles ■ Score line processing is effective for materials that tend to experience springback or when a significant bend around 90° is desired. ~ For any requests regarding non-metallic material pressing or bending processing, please leave it to us! ~ *For more detailed information, please refer to the PDF materials.

This processing method uses human hands for the bending technique. It is a simple method, but it is common to combine this method with previous thermal bending processing and score line processing for bending. Furthermore, if there are high demands for bending position and angle, we use bending jigs that match the product shape and bending shape for precise bending. [Features] ■ When not combined with score line processing, there are no initial costs for the bending process itself, making it very cost-effective when the number of processed items is small. ~ For any requests regarding non-metallic material pressing or bending processing, please leave it to us! ~ *For more detailed information, please refer to the PDF materials.

We will introduce basic information and know-how related to insulating material processing from a perspective that only we can provide. Please read this before selecting materials or processing. The "U-bending process (bending die)" involves clamping the material between a punch and a die, applying pressure to bend it into a specified shape. Basically, it is almost the same method as bending metal materials. However, depending on the material, the return angle during the occurrence of the springback phenomenon can become very large. [Features] ■ This method, which combines bending dies and equipment for processing, has the potential to reduce running costs significantly. ■ Compared to manual labor, it tends to have less load and higher output. ■ The reproducibility of bending angles (less variation) is superior to other methods. ~ For any requests regarding press processing or bending of non-metallic materials, please leave it to us! ~ *For more detailed information, please refer to the PDF materials.

The molds, which are essential to our processing technology, have been produced in-house since our founding. We not only manufacture molds that are suitable for resin pressing and enhance technical evaluation for products, but we also conduct maintenance in-house, establishing a consistent processing system from mold design to assembly, which contributes to increased productivity. The manufacturing of these molds and the development of other equipment are primarily carried out by our technical team, and we actively respond to customer needs by developing specialized equipment tailored to their requests and challenges. 【Processing Steps】 ■ Rough Processing ■ Shape Processing ■ Finishing Processing ■ Measurement and Analysis ■ Assembly *For more details, please refer to the PDF document or feel free to contact us.
