Talk to the Person Who Runs the Factory
Send your part today and you'll have a quote, DFM feedback, and a realistic timeline within one business day.
Every inquiry lands in Frank's inbox, the second-generation owner who opens your CAD file himself. There is no account manager between you and the workshop, so the person who answers your question is the person who will make your parts.

Call Now →What to Include in Your Inquiry
The more you send up front, the more useful the first reply gets. A complete package below usually means a quote with no follow-up questions.
Technical Details
- 3D CAD files: STEP, IGES, STL, Parasolid, SolidWorks, Creo, or AutoCAD
- 2D drawings: PDF or DWG with tolerances, GD&T, and critical-to-function features
- Material specification: or describe the application and we'll recommend one
- Surface finish and appearance: texture, color, polish grade
- Secondary operations: ultrasonic welding, inserts, printing, assembly
Project Context
- Annual volume target: this drives the tooling strategy and pricing
- Initial order quantity: for sampling or the first production run
- Target delivery timeline: when you need the first shipment
- Target price per unit: optional, but it saves a negotiation round
- Regulatory requirements: RoHS, REACH, or country-specific material compliance
- Destination country: for the shipping quote and export paperwork
Missing half of this? Send what you have. Plenty of good projects started here as a photo of a worn part and two sentences.
"Your message comes straight to me, not to a ticket queue. I open the CAD file myself, walk it past our mold makers if I need a second opinion, and reply with numbers you can actually plan around. If we're not the right factory for your part, I'll tell you that too, and point you somewhere better."
