Sheet Metal Prototyping for the Next Generation of Infrastructure
Turn complex CAD models into functional metal prototypes. Sintel’s vertically integrated facility accelerates your product development from concept to full-scale production.
01
Why Choose Sintel for Sheet Metal Prototypes?
Sintel combines the speed of rapid prototyping with the engineering depth of a high-volume OEM partner.
01
Every prototype project begins with a consultation to identify cost-saving opportunities, reduce weight, and improve manufacturability.
02
Scale Without Friction
Our facility is designed to easily scale your large-part prototype into production runs of 5,000+ units, using high-quality equipment.
03
Vertical In-House Process
From laser cutting and robotic welding to in-house powder coating and assembly, we handle the entire timeline to ensure on-time delivery. Our prototypes are engineered for our 30,000 lbs/hr paint capacity and automated vertical lines.
04
OEM Partnership
We partner with you from start to finish, optimizing your design to handle heavy, large parts that no one else can.

Our Prototyping Capabilities
1. Large & Heavy Weldment Processing
We engineer massive weldments for Data Centers. Our prototyping phase tests the limits of weight and scale.
-
High-Speed Cobots: We apply the same robotic technique in prototyping as in production to ensure consistency.
2. Industry-Leading Finishing (The "Big Powder" Advantage)
Stop designing prototypes around small oven constraints.
-
Massive Capacity: Prototype parts up to 53’ x 14’ x 14’.
-
Large Powder Coating: Engineered for 30,000 lbs/hr, ensuring your prototype finish matches the durability of your final production run.
3. Optimized Logistics
Our facility features drive-thru truck loading/unloading, meaning we can move your massive prototypes from our floor to your testing site with zero friction.

The Process: From Prototype to Production
1. Design & Upload:
Upload your 3D CAD files. Our engineering team reviews your design for material utilization and feature proximity to bends.
2. Engineering Collaboration:
We provide feedback on how to optimize your part for "Real World" manufacturing, helping you avoid costly design changes during the production phase.
3. Rapid Fabrication:
Your parts are cut, formed, and finished in our facility.
4. Quality Assurance:
Every prototype undergoes extensive inspection to ensure it meets 99% first-pass quality yields before it leaves our dock.
