Vespel® Custom Plastic Parts

DuPont works closely with part designers to customize design, material and production method for the desired end-use results.

Vespel® custom plastic parts are specified where the material and design are key for success in the application. The manufacturing method chosen is based on a number of considerations including part geometry and economics. Vespel® parts and shapes are ISO-9001 and ISO-14001 certified.

Types of Manufacturing Methods

Molded Finished Parts

Large quantities of custom plastic parts, geometry permitting, can be molded with little/no to little or no machining.  This is the most economical method for production of large quantities with wider tolerances.

Molded and Machined Finished Parts

When tight tolerances or complex geometries is required, machining to achieve final part dimensions is applied after molding. Vespel® parts, unlike other polymers, can be easily machined with the usual machine tools and will yield very smooth surfaces.

Assemblies

When metal or ceramic mating components are required, insert-molding, mechanical attachment, and/or bonding is always an option to provide more design flexibility and overall part functionality.  DuPont engineers can help evaluate various assembly techniques to meet performance and cost requirements.

Injection molded parts

In high volume applications where thermoplastic resins can be used, injection-molded parts allow design engineers increased geometric options without the added cost of secondary machining. Multiple components may be incorporated into a single part, reducing tooling, inventory and part handling costs. Injection-molding manufacturing is frequently used for automotive or aerospace parts.

CASE STUDIES

Vespel® SCP-5050 sweep-out fingers and stacker bar inserts for glass handling help increase plant reliability and efficiency and reduce operating costs at Veda-Pack glass manufacturing sites

The operator of a pipeline in the Southwestern U.S. was searching for a case ring material for pumps that would enable improved operating efficiency, increase equipment reliability and avoid the seizing or galling problems encountered with metal components. The metal components were replaced with Vespel® CR-6100 parts, and the results were impressive.
