Injection Moulding Optical Parts for the Automotive Plastics Industry

ENGEL Expertise and Solutions for Light Guides, Lenses and More

Processing PMMA, PC and silicones for optical applications in the automotive plastics industry poses a challenge. The smallest defects and impurities reduce product quality. Master difficult tasks with ENGEL injection moulding machines: gentle plasticising as well as precise and pure products thanks to machine design with a focus on cleanliness.

Advantages ofwhen Producing Optical Plastic Parts with ENGEL Machines
Gentle plasticising for crystal-clear results

Melting the material as gently as possible is essential when producing optical parts for the automotive plastics industry. Even slight overheating causes yellowing, which impairs the optical performance of the component. We develop and produce our plasticising components ourselves. At ENGEL, we provide you with customised screws and barriers for the best possible melt quality. Specially developed for optical materials.

Precise injection moulding machines for best dimensional accuracy

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

The right injection moulding machine for every application

Thick-walled lenses, silicone optics, light guides and 2K reflector housings are examples of components made for automotive plastics. They come in countless sizes and shapes. Thanks to our extensive portfolio of injection moulding machines and automation, you get the right ENGEL solution for every product. You invest in exactly the system you need and avoid unnecessary expenditure and compromises.

Optimum product quality with ENGEL expertise

Benefit from the extensive know-how of our application engineers, especially for difficult optical plastic applications in the automotive industry. We have developed our own injection moulding processes such as ENGEL optimelt to achieve the optimum in quality and productivity for you. In this way, we enable you to inject multi-layer lenses without a boundary layer in a single cycle.
