Technologies

This technology realizes a three-layer structure of GFRP（Glass Fiber Reinforced Plastics）, GMT（Glass-Mat reinforced Thermoplastics）, and steel.
This engine undercover is made of GFRP, which is as strong as steel but lighter, and is 76% lighter than conventional covers. In addition, the replacement of steel with resin improves the anti-corrosion performance.

We have a molding method that enables manufacturing using only polyurethane foam thanks to the development of a special polyurethane foam material. We have realized a weight reduction of 24% for the engine covers that adopt this technology compared to conventional products as we use lightweight polyurethane foam. In addition, by integrating fastening parts and eliminating coating, costs have been reduced by 27% compared to conventional products. Using flexible polyurethane foam also contributes to improved pedestrian protection.

Polyurethane foam, which is a vibration-proof material with a high sound-absorbing effect, is integrally foamed on the back surface of the nylon engine cover, and exhibits excellent sound-absorbing, sound-insulating, vibration-proofing, and vibration-damping performance. In addition, polyurethane foam can also withstand the harsh environment of an engine compartment with its heat resistance, and due to foam molding technology that makes use of shape flexibility and low-noise designs that are gentle on the surroundings, engine noise is greatly reduced.

The nylon resin cover is foamed internally to reduce the amount of resin used, thereby reducing weight and cost. In addition, it also has a paint-free exterior and realizes the same rigidity as conventional methods (solid). We have achieved a weight reduction of 30% for the engine covers that adopt this technology compared to conventional products.

Special film is preformed 3dimensional shape and installed in die mold.
The special film is formed with resin (injection molding) by welding to form the finished parts.
Deep drawability of film improves design.

We use surface processing that gives color by coating the surface of the material and drying it. With this coating, it is possible to color products in various colors. In addition to conventional metallic coating, we also excel at metallic coating with a lustrous feel and mask coating in which a single part is coated with various colors.

This is a surface treatment that makes a resin molded product covered with a metallic film. It is possible to apply a luxurious metallic color tone to the surface, and it is also possible to create a metallic feel with different color tones and luster.

Thermal transfer technology is a processing technology that transfers metallic characters, designs, etc. by pressurizing and heating hot stamping foil.

We reduce product defects and the number of trial processes by predicting the pressure, temperature and curvature deformation of resin during injection molding, and determining the product shape and mold specifications.

We can identify stress concentration points by analyzing the deformation and stress of products due to external and internal forces. Those results are incorporated into designs to prevent defects in advance.
