HMTooling helped develop the optical design for this small acrylic lens. The output values and distribution was incredibly important, needing to be accurate in relation viewing angles and light output.
The part was produced using prototype inserts before we supplied a fully hardened 18 impression Tool. A specialised Hot Runner keeping the part pitch down to just 18mm was used. This enabled the tool size to be kept to a minimum allowing for a smaller press to be used for moulding.
