Recently, the national standard project Plastic Injection Molds for Light Guides, led by Preh GmbH, a subsidiary of us, was officially approved and issued by the Standardization Administration of China.
In fact, existing standards for plastic injection molds in China and overseas are primarily focused on general-purpose molds and standardized components, with no dedicated technical specifications specifically addressing plastic injection molds for light guides – a high-end segment of the optical mold industry.
The approval of this project marks an important step forward in advancing the standardization of plastic injection molds for light guides.
