High-Gloss Optical Module Processing

Optical polymers are typically hygroscopic. Moisture in the melt can create bubbles and microvoids, which reduce gloss and increase haze. Therefore, we require an injection molding dryer with a proven inlet dew point (typically ≤ -40°C for polycarbonate). It is directly related to surface finish, light transmittance, stray reflections, and the perceived quality of automotive, medical, and consumer optical parts. Therefore, gloss must be considered as a holistic. High-gloss (optical) plastics usually refer to plastic materials with excellent optical properties, and common materials include polymethylmethacrylate (PMMA), polycarbonate (PC), and polystyrene (PS). These materials can have excellent transparency, scratch resistance, and optical uniformity after. High bandwidth demanding applications such as high-performance computing and hyperscale datacenters are drivers for co-packaged optics, which aims to bring optical signals as close as possible to the electrical computing chips by integrating the electro-optic transceivers and ASICs on the same. In injection molding, the surface quality of a product depends not only on the plastic material and process parameters but is also directly influenced by the surface condition of the mold. Especially for optical components, high-gloss housings, or plastic parts with extremely high appearance. This article highlights the critical design and process considerations for achieving flawless surfaces in electronic injection-molded parts.
