Medical Lens, Hard Over Hard

A clear lens for a medical device, moulded hard over hard in one tool.

Clear parts show every defect. Flow marks, weld lines and any trace of moisture in the resin end up visible, so the process window is narrow and the tool has to be right the first time.

We build the tool with polished optical surfaces and run trials until the part is clean at the specified cycle, then document the parameters that produced it.

Send the 3D, the optical requirement and the resin you intend to use for a DFM review. Feedback is normally returned within two working days.
