Today, UV curing is being done very successfully on complex, three-dimensional parts including automotive lighting assemblies, plastic molded parts such as mobile phone cases and other teletronic devices, contoured wood products, golf balls, electric motor housings and fiberglass composite parts.
UV curing of complex shaped parts can be a challenge because UV curing is "line-of-sight", meaning that every point on a surface must see the UV to cure the coating. Hidden or shadow areas will remain uncured (remain wet).
Heraeus Noblelight America has worked extensively on 3-D curing projects. We've made tremendous strides on a wide variety of products previously thought impossible. The information resources listed below can help you decide whether UV curing is right for your 3-D product or part. Just click on the links to learn more.
