Transparent components are essential in a range of industries, from medical diagnostics to consumer electronics and automotive lighting. When speed, cost-efficiency, and visual clarity are all priorities, urethane casting emerges as a powerful solution for prototyping and low-volume production of clear parts. However, achieving both optical transparency and mechanical strength in urethane-cast components requires more than just selecting the right resin. Every stage—from master pattern quality and mold preparation to casting conditions and post-processing—affects the final result. There is a range of essential factors to consider to ensure the production of clear and strong cast urethane parts. It demands careful consideration of the material, mold design, casting procedure, and appropriate finishing methods.…
