The Shell Molding Process
Pre-Coating: Industrial sand is thoroughly pre-coated with a synthetic bonding resin.
Pattern Application: A heated metal tool pattern is evenly coated with the resin-sand mixture.
Thermal Curing: Heat cures and hardens the material into a rigid shell measuring 0.5″ to 1″ thick.
Shell Stripping: The cured shell halves are stripped from the pattern and glued together to form a central cavity.
Metal Pouring: Molten metal is poured directly into the assembled shell mold on our conveyor line.
Cooling & Finishing: After cooling, the sand shell is stripped away, recycled, and prepped for final surface machining.

FAQ for your new project
Why X-Pro?
We connect you with the best designers in the business, and we offer the most comprehensive set of services for inventors you’ll find anywhere. We take the guesswork out of online design services, and let you focus on what’s important.
How do private projects work?
Simple. Just send us a project brief and we will provide you with a design quote from a pre-qualified designer for your project.
Who can see my project?
Private projects are entirely confidential. Only you and the designer that you will be working with will see your project description, file attachments and submitted work.
Do I own the designs & IP?
Yes. Our legally binding terms of service assign the ownership of intellectual property (IP) from the designer to the service buyer for any paid designs.
Do you offer manufacturing services?
Yes we do! We offer a range of manufacturing services, including 3D printing, rapid manufacturing and conventional injection molding.
How is a design project different from hourly services?
Design projects are limited-term projects with a concrete budget, based on an upfront quote from the CAD designer. Hourly services are for ongoing work that generally have an open work scope.
Will designers sign a NDA?
We’ve got this covered. Our legally binding terms of service covers freelancer non-disclosure. Freelancers on X-Pro have agreed to and are bound by the terms of non-disclosure that are outlined in our terms of service.
