“O&O mdc” ERTALYTE® MANDREL FOR DAC ALM & MLC SERIES

ERTALYTE® Mandrel made IOL manufacturing with DAC lathe:

Ertalyte® is an unreinforced, semi-crystalline thermoplastic polyester based on polyethylene terephthalate (PET-P). It is manufactured from proprietary resin grades made by Quadrant. Grinded to perfection at the lowest tolerances, the mandrels are used and machined by a DAC ALM lathe or MLC Combo machine equipped with “Dead Length” collet. Made to facilitate your IOL manufacturing process, the O&O Mandrels will allow you to use water soluble wax.

Manufacturing process using O&O ERTALYTE® Mandrel:

Upper row:

Take an O&O Ertalyte® Mandrel (1) and lathe it as a collet on DAC lathe (2);
Heat the mandrel to 65°C and place the cold 16.0 mm blank into the mandrel, which will be held in place by contraction.
Lathe (4) with a 15.8 mm seat, then mill (5) the blank from the back side.

Lower row:

Take a O&O Ertalyte® Mandrel (6) and lathe it as a mirror image of the back side of your lens (with a 0.02 mm gap for wax) on DAC lathe (7), then drill a 3.0 mm hole for wax overflow;
Heat the mandrel to 65°C and place it in the upper collet of the blocking station (8), dispense water soluble wax on the first side of the machined blank (9) and block the two mandrels face to face (see http://www.larsenequipment.com),
Deblock automatically, using the outside groove on the first side mandrel,
Place the second side mandrel with its waxed blank in the DAC lathe (10),
Lathe (11) the front side of your lens,
Deblock your lens by any method.
