河長樹脂工業 Product Lineup

At Kawachou Resin Industry, we offer "CAE/Flow Analysis." With over 10 years of experience in flow analysis, we conduct flow analysis during mold production, allowing us to identify issues and make suggestions during the design review before production. This enables us to implement measures before the mold is produced, reducing time and costs until mass production begins, while enhancing quality and stability. 【Features】 ■ Over 10 years of experience ■ Ability to identify issues and make suggestions during the design review before production ■ Simulation and visualization of resin flow inside the mold based on a 3D model ■ Predictable phenomena that may occur during the injection molding process, including flow and solidification *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the press products of Kagawa Metal Precision Co., Ltd. In the "Transistor and Composite Frame" category, we supply various lead frames and offer plating options including Au-Pd, Ag, and Sn. In the "Punching and Bending Composite Lead Frames" category, we add bending processes to lead frames, contributing to material usage reduction. In the "Bending and Drawing Composite Process Products" category, we combine bending and drawing techniques, which can be utilized as remote control noise cancelers. In the "Sheet Metal Cases" category, we specialize in composite bending cases made from thin materials, providing consistent production support from prototyping to mass production to meet our customers' stringent needs. For more details, please contact us or refer to our catalog.

• Press Dies

We would like to introduce the press processing of our subsidiary, Kawanaga Metal Precision Co., Ltd. The press component "Aluminum Reflector" is a reflector for LEDs, and since component placement is done around the chip and on the top surface, it requires relief in the vertical direction. At Kawanaga Metal Precision, we utilize extrusion processing and hammering of materials to create the necessary relief for components. This allows for manufacturing without changing the components. 【Press Products】 ■ Shield Cases ■ MEMS Caps (6-axis) ・ Portable Orientation Sensors ・ Games and Navigation ■ Remote Control Receiver Cases ・ Noise Cancelers *For more details, please refer to the PDF document or feel free to contact us.
