Plastic Molding Services: Dip Molding

Among the many different methods available from many companies supplying plastic molding services is dip molding. Dip molding describes a specific method of producing a molded part. With its roots in the United Kingdom and America, it continues to grow its markets in these countries.

What Is Dip Molding?

Producing a component using this method involves dipping a mold, form or mandrel into a polymer bath. This attracts a thin layer of film deposit raising it out of the bath. The next step is to dry the film before removing it and returning to the initial dipping process. A complete dipping cycle can take anywhere between four to 50 steps to complete. Companies providing these type of plastic molding services prepare the component from various materials. While the most common is the affordable and easy to process plastisol, natural rubber latex, and urethane.
