Multi-component and co-injection molding can help low piece part costs by eliminating consolidating multiple molding and assembly steps into a single process. Think of multi-component systems as manufacturing cell. "It's not just a molding machine," says Bob Hare, general manager of Ferromatik's North American Operation, about one of the company's most recent multi-component systems. "It is a means to produce fully assembled parts that are ready for the market as they come off the machine."
And there's more to multi-component than reducing manufacturing costs. Multi-component technology allows material combinations and designs that differentiate the products, allowing a higher price. "Typically, if you have a multi-component part, especially in the consumer industry, you can achieve a significantly higher margin than with any single-component part," notes Joachim Kragl, manager, Processing Technologies, Engel.
Here's a look at some of the most recent systems that help make multi-component molding possible.
