Why ProtoForge
A clear path from design files to finished parts
- Process-aware reviewEvaluate the part in the context of geometry, material, finish and quantity.
- Multi-process manufacturingMatch CNC, additive, sheet metal, casting or tooling routes to project needs.
- Confidentiality readyRequest an NDA before sharing sensitive design information.
- Practical communicationKeep engineering requirements visible from RFQ through delivery.
How it works
A manufacturing process built around engineering clarity
- 01
Share requirements
Upload CAD files and describe material, finish, quantity and project context.
- 02
Engineering review
Review manufacturability, open questions and the appropriate production route.
- 03
Manufacturing
Proceed against the confirmed scope and approved project requirements.
- 04
Inspect & deliver
Document agreed inspection needs, protect parts and coordinate delivery.
Materials & finishes
Choose around performance, environment and appearance
The public material and finish catalog will grow as available options are verified. Use the guides to define project needs without assuming unsupported capability.
The pictured samples illustrate selection discussions only. Specific grades, colors and finishes remain subject to project review and availability confirmation.
Quality assurance
Define what matters before production begins
Communicate critical dimensions, functional interfaces, cosmetic expectations and inspection needs with the RFQ. Verified equipment and capability data will be published only after confirmation.
Packaging & delivery
Protect parts for the journey from factory to destination
Packaging and delivery requirements should be agreed around part geometry, surface protection, quantity and destination. Shipping arrangements are confirmed per project.
Future case studies
Evidence-led project stories, once verified
These editorial slots are ready for real project context, approved photography, measurable requirements and customer-authorized outcomes.

Common questions before requesting a quote
What information should I include with an RFQ?+
Share your CAD files, material preference, finish, quantity, target date and any critical functional or inspection requirements. The team can then review the project context.
Can I request an NDA before sharing CAD files?+
Yes. Select NDA required on the quote form or contact the team before transferring confidential design information.
Which manufacturing process should I choose?+
The right process depends on geometry, material, quantity, functional needs and project stage. Share those constraints for process-selection guidance.
Do you support robotics and Physical AI hardware?+
ProtoForge focuses on the physical components behind robotic systems, including housings, mounts, brackets, frames, shafts, enclosures and functional prototypes.
