Competitive optical component technology

摘要

To cater to the industry's use of polymers, instead of glass, in optical components, Austrian injection moulding machinery maker Engel has introduced a new technology known as Optimelt, featuring optimised plasticising units for processing transparent polymers. Overmoulding is also used in Optimelt and it starts with the production of a pre-moulded part that is recoated with additional layers (usually of the same material) in one or more subsequent stages.
