How we work
Simple and predictable: quote fast, build right, communicate clearly.
1
Send files
Drawing + model + qty/due date. If it’s messy, we’ll clarify quickly.
2
Get a quote
Clear pricing, lead time, and notes about risk areas (tolerance/finish).
3
Build & inspect
Fixture smart, machine accurately, check critical features as we go.
4
Deliver
Pack well, ship on time, and keep you informed if anything changes.
Quality & reliability
Manufacturing discipline without the bureaucracy.
Process control
Workholding, tool strategy, and inspection points built into the plan.
Communication
No surprises. If something looks risky, you’ll hear it early.
Continuous improvement
We refine setups and cycle time on repeats to reduce cost and lead time.
What customers say
Short runs, tight timelines, and parts that fit the first time.
“They caught a tolerance stack issue before it became a problem. Parts arrived ready to assemble.”
“Fast quote, honest lead time, and clear communication. Exactly what we need in a supplier.”
“Prototype turned into a repeat job. They tightened the process and reduced cost on the second run.”
FAQ
Quick answers to the common questions.
What file formats do you accept?
PDF for prints and STEP/IGES for models are ideal. If you only have a sketch, send it—we’ll work with you.
What size jobs do you take?
Prototype through small-to-mid batch production. If it’s larger, we’ll still review and advise.
Can you handle finishing?
Yes—common finishes can be coordinated through trusted partners. Tell us what you need and your timeline.
How fast can you quote?
Many quotes go out within 24–48 hours depending on complexity and how complete the package is.
