Our Fabrication Process

A systematic approach from concept to completion

1

Consultation & Design

We start by understanding your requirements. Our engineers work with your team to develop CAD designs optimized for manufacturability.

2

Material Selection

We help you choose the right materials - aluminum, stainless steel, carbon steel - based on your application requirements and budget.

3

Prototyping

We build functional prototypes to validate your design. Test, refine, and perfect before committing to production.

4

Production

Once approved, we scale to production with consistent quality. Our processes ensure every part meets specifications.

5

Quality Control

Every component undergoes thorough inspection. We document and verify dimensional accuracy and weld quality.

6

Delivery

Parts are carefully packaged and delivered on schedule. We coordinate with your timeline and logistics requirements.

Fabrication FAQs

Common questions about our metal fabrication services

For accurate quoting, please provide CAD files (STEP, IGES, SolidWorks) or detailed drawings with dimensions. Include material specifications, quantity needed, finish requirements, and timeline. Even a sketch or concept description helps us understand your project for an initial estimate.

We have no minimum order quantity. We welcome single prototype orders as well as production runs of hundreds of pieces. Our flexible setup allows us to efficiently handle both one-off custom projects and repeat production orders.

Absolutely! Our in-house engineering team can take your concept, sketch, or even just an idea and develop it into production-ready CAD designs. We offer complete design-to-manufacture services and work collaboratively with clients throughout the development process.

We coordinate finishing services including powder coating, anodizing, plating, painting, and polishing through our trusted partners. We can deliver fully finished parts ready for use, managing the entire process for you.

Lead times vary by project complexity. Simple parts may ship in 3-5 days. Prototypes typically take 1-2 weeks. Production orders depend on quantity and scheduling. Rush services are available. Contact us with your timeline and we'll do our best to accommodate.
