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 Molding

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.

Reel to Reel Insert Molding

In reel to reel insert molding, a stamped metallic strip containing inserts on a carrier brings the metallic inserts into and out of an injection mold.  During molding, plastic is injected over the inserts to create the desired part.  Rather than separating the parts as they exit the mold, the parts are left on the carrier and spooled up for shipment or additional processing.  This method often simplifies part handling in later operations such as plating and final assembly and is a great way to make small, high volume electrical components.

Sub-assemblies

Along with the capability to make components using several manufacturing technologies, DNI also can combine these components into sub-assemblies to reduce part count and simplify final assembly for our customers.  We can combine stamped parts, cold formed parts, turned parts, plastic molded parts, magnets, seals, wires, powder metal parts, or extruded parts into sub-assemblies that add significant value to our customers’ final assemblies.  With manufacturing locations in Mexico and the US, DNI can develop cost effective methods to assemble parts in volumes from hundreds by using manual operations to millions by using sophisticated automated production lines designed and built in-house.
