INEOS Styrolution and Ichikoh Japan jointly develop a laser weldable high heat ABS for rear lamp

  • New laser welding process by Ichikoh Japan ensures optimal aesthetics and greater design flexibility
  • Custom-developed high-heat ABS grade from INEOS Styrolution’s Novodur® HH product line offers superior welding performance for laser welding process

    • New rear lamp housings for vehicles can now have an even greater aesthetic appeal and performance thanks to material and processing innovations from Ichikoh Japan and INEOS Styrolution. These innovations are the results of a new laser welding technique developed by Ichikoh and a unique styrenic polymer solution from INEOS Styrolution. Ichikoh manufactures the part using a specific black colored Novodur HH-112 developed from INEOS Styrolution’s high-heat acrylonitrile butadiene styrene (ABS) product line. This polymer is ideal for Ichikoh’s newly developed laser welding process as it offers a good appearance at the welding areas of the plastic parts when compared with other polymers. Overall, the new material and laser welding process have a significant impact on the design and production process of the rear lamp housing, lending the hybrid an even sleeker look and helping to reduce total production costs. This new technology was introduced into the Japanese market in November 2015. Novodur HH-112 is now available globally from INEOS Styrolution.

    Key points:

  • Ensuring aesthetics and greater design flexibility through new laser welding process:  Ichikoh Japan wanted a processing solution that could achieve good appearance at the welding areas on plastic parts. However, this would be impossible to achieve with conventional welding techniques such as hot plating or vibration welding due to complicated part designs and shapes. For this reason, a new laser welding technique was utilized for the rear lamp housing to facilitate more design freedom and achieve the required surface appearance. In addition, this new laser welding technique also has the potential to generate more stability and higher mechanical strength at welded areas compared to conventional welding methods.

  • The right material solution to drive design innovation and performance: The challenge with most black or dark colored polymers is the materials’ high sensitivity to laser beam, resulting in uneven surfaces at the welding area when a laser beam is applied. As such, Ichikoh sought to find a polymer solution that would not only optimize the process to achieve suitable laser welding conditions but would also adhere to the substrate and most importantly, a great looking finished product. Ichikoh partnered with INEOS Styrolution to select the right styrenic polymer for the application. Working in collaborative innovation, INEOS Styrolution custom developed Novodur HH-112, a high-heat ABS specialty styrenic grade that would offer the performance and aesthetic qualities they require. This marks the first time an ABS resin has been used for a black color laser welded application.

    • In the end, the leading Japanese car manufacturer was pleased with the vastly improved part appearance at the welding area. The new process and polymer solution also helped the car manufacturer improve the quality of their cars design.

  • Novodur HH-112 now globally available: Novodur high-heat ABS grades meet stringent stability requirements for thermally stressed components. Novodur high heat is the material of choice for numerous heat-resistant applications, like rear lamp housings, radiator and front grilles, as well as exterior trims. The new Novodur HH-112 product is now available globally from INEOS Styrolution.
