Plastic Overmolding

Deringer-Ney manufactures millions of parts using the insert-molding, or over-molding method.  During insert molding, one or several metallic parts (inserts) are placed into a mold cavity and held in place.  The mold is closed and plastic is injected around the inserts into the desired shape as defined by the shape of the mold cavity.  The mold is then opened and the finished part is removed for additional packing or additional processing.

Insert molded parts combine the functionality of metallic components (like strength and electrical conductivity) with the design versatility of the plastic molding process.  Insert molded parts combine several components into single part eliminating the need for additional assembly operations.  These parts typically perform multiple functions which reduces cost and complexity for our customers.
