Match material,
process and finish.
Material choice affects machinability,
forming, appearance, corrosion resistance
and cost. Surface requirements can also
change tolerances and the order of
operations.
Aluminum Alloys
Stainless Steel
Carbon Steel
Brass & Copper
POM
Nylon
Project-specific plastics
Anodizing · Coating · Plating · Appearance Control
Confirm finish specification, masking, color, surface zones and dimensional
impact during quotation.
MULTI-PROCESS PROJECTS
One project. Fewer handoffs.
When a finished component needs several operations, the process plan matters as much as each individual step. We coordinate the
sequence, interfaces and inspection points around the final requirement.

Before You Start Your Project
Common Questions
Before an RFQ
Concise answers should resolve buyer concerns
and link to the most relevant service, material,
quality, or case page.
What CAD and drawing formats can I upload?
You can upload the following CAD and drawing formats:
2D CAD: DWG, DXF, DWT
3D CAD: STEP, STP, IGES, IGS, SAT, SLDPRT, SLDASM
Drawing & image files: PDF, AI, EPS, PNG, JPG, TIFF, BMP
Please note that image‑based files are only for preview and cannot be edited as CAD data.
Can you support a one-piece prototype and later production runs?
What tolerances can you hold on custom aluminum parts?
How do you manage anodized color and cosmetic appearance?
How do you handle inspection, packaging, and international delivery?
Ready To Start Your Project?
Start With Your Drawings - or Tell Us What You Need
Upload drawings, photos, or reference files if available and share your project requirements. Once the requirements are complete, most
standard RFQs are quoted within 24-48 hours. Complex or multi-process projects may take longer.
Drawings handled confidentially · NDA available on request
