Painting, Pad Printing & Screen Printing
Post-Mold Machining & Surface Finishing
Assembly & Packaging
Secondary (post-injection molding) processes are used to add functionality, precision or assembly features that can’t be achieved through molding alone, such as machining tight-tolerance details, welding components together or delivering fully-assembled parts. These steps help ensure parts meet performance, regulatory or application-specific requirements.
Post-processing is also used to enhance appearance and branding through finishing methods like painting or printing, and to simplify logistics with ultrasonic welding, packaging or kitting. At Fathom, we offer these services to save you time, reduce handling and improve overall product quality.
Adds color, surface protection or a cosmetic finish to parts using methods like spray paint or powder coating.
Joins plastic components by melting and fusing them together for added strength and structural integrity.
Inserts metal or deforms material with heat to mechanically secure components such as fasteners within or to the part.
Uses CNC machining after molding to refine features, remove excess material or prepare parts for further finishing.
Applies logos, graphics or labels to parts for branding or identification using printing techniques.
Completes product build-out by assembling parts and packaging them to make them ready for shipment or sale.
Partner with Experts Who Get It Right the First Time
Every project is reviewed by a seasoned manufacturing engineer to optimize part design, material selection, and tooling strategy — ensuring smarter decisions before steel is cut and production begins.
Secondary processes are value-added operations like painting, welding, machining, assembly and packaging. They are performed after the part is molded to enhance its function or appearance.
Post-processing ensures your parts are fully finished, assembled and ready for use or sale when they arrive at your site.
Fathom offers decorating and finishing options such as painting, pad printing and screen printing for enhanced visual appeal.
Yes. Processes like ultrasonic welding, hot plate welding, heat pressing and heat staking are used to permanently join parts.
Yes, post-molding CNC machining can refine part features, remove excess material or prepare parts for additional secondary processes.
Yes, Fathom can assemble your parts during post-processing so they arrive fully assembled and ready for you to use.
Yes. Completed parts can be packaged into consumer-ready formats such as boxes or clamshells before shipment.
You can select desired secondary processes when submitting your CAD file through Fathom’s online quoting system.
Yes. The specific secondary steps depend entirely on the intended end use and required functions of the finished product.
