Injection Molding Optical Parts for the Plastics Automotive Industry

ENGEL Expertise and Solutions for Lighting, Light Guides, Lenses, and more

Processing PMMA, PC, and silicones for optical plastic applications in the automotive industry is challenging. The smallest defects and impurities reduce product quality. Master difficult projects with ENGEL injection molding machines: gentle plasticizing of pure resins on precise machines designed for clean production.

Advantages of Producing Optical Parts with ENGEL Machines
Gentle plasticizing for crystal-clear results

Melting the material as gently as possible is essential when producing optical parts for the plastics automotive industry. Even slight overheating causes yellowing, which affects the optical performance of the part. We design and manufacture our plasticizing components in-house. ENGEL provides customized screws for the best possible melt quality – especially developed for optical materials.

Precise injection molding machines for best dimensional accuracy

Optical components such as lenses must conform to a precisely calculated geometry. The precise movements of our electric injection molding machines provide the necessary reproducibility. Our digital assistance systems, combined with special molding processes, ensure the greatest possible accuracy for every shot. For multi-cavity molds, we have developed a tie-bar-less clamping unit with even clamping force distribution and the best possible platen parallelism.

The right injection molding machine for every application
