High Volume Bioabsorbable Micro Component Production

How to Ramp Up Production While Decreasing Piece Part Price

When OEMs prepare to increase production volume of a micromolded component, many focus on multi-cavitation tooling as a strategy to reduce piece part price. While increasing cavitation may be a cost-effective approach for higher volumes of simple thermoplastic parts, it is typically not the best approach for micromolded parts, especially those that are bioabsorbable, or made from other high dollar value materials.

The Smallest Part in the World

From late 2010 to 2012, MTD Micro Molding successfully molded an EVA ophthalmic part that weighs in at 0.00000313 grams. It is an ophthalmic implant for glaucoma treatment. This feat required MTD’s Sarix technology to make a precise gate needed for such a tiny part. The gate measured .0018 x .0008 inches.
