In-mold assembly made more flexible with new rotary cube mold


If you have every seen a rotary cube mold in operation at a trade show or in an injection molding shop, you know how impressive these can be. These molds help processors take the "pellet-to-part" philosophy to an extreme as truly complicated multi-material parts exit the mold, ready for shipping.

But in life there is no free lunch (Ed. Actually we are offering you one in our Price Wise Challenge), and the price of these molds is very high, typically measured in the millions of dollars. Or at least the price always has been high in the past, which is why buyers of these molds usually are huge multi-national fast moving consumer goods companies requiring outputs of some parts in the hundreds of millions per year. But one mold maker, Zahoransky, says it has a new development that bests other rotary cube molds on output and flexibility, traits it says will help reduce the payback period for these molds.

The company is calling its patented technology a TIM (Total Integrated Manufacturing) stack mold. Zahoransky is known both for its injection molds as well as its automation / assembly systems, and it seems to have combined these competencies in this new development. The TIM mold consists of two mold halves with an axial rotary cube, allowing two different parts to be made on a single mold....
