02DFM & tolerance stack-up

Review design choices before production.

A design review can flag wall thickness, bend radius, tolerance and assembly risks before tooling or production is approved.

03Primary fabrication & tooling

Flat stock and raw metal become precision components.

Laser cutting and forming suit many sheet parts. Stamping or injection molding may suit repeat production after tooling cost and volume are reviewed.

  • Material records by agreement
  • Laser & CNC forming
  • Custom tooling

Quality documents by scope

Ask which facility will make the part and which certificates or inspection documents can be supplied for that order.

Confidentiality requirements

State your confidentiality and file access requirements before drawings are shared for quotation.

Prototype to volume

Agree sample approval, tooling ownership and change control before repeat production.

Named order contact

Confirm who owns quotations, drawing changes, inspection questions and delivery updates.

FAQ

Common questions.

What if I only have an idea or a rough sketch?

Send what you have. We can discuss the engineering work needed before a manufacturing quote, including whether a production drawing is required.

Where are products manufactured?

The production location and facility details should be confirmed in the quotation for your part.

Which countries do you deliver to?

Share the destination so available freight options and import responsibilities can be confirmed.

Can we order a small pilot run before committing to volume production?

Pilot quantities depend on the process and tooling. Send your target quantity and intended production volume for a suitable route.

What file formats can I send?

PDF, DWG, DXF, STEP, IGES and clear photos. Sketches on paper are fine too.

What are your minimum order quantities?

Minimums vary by process, material and tooling. State both your first order and annual demand when requesting a quote.

How do you protect our designs and intellectual property?

Tell us if an NDA or restricted file access is required before you share confidential drawings.

Who handles customs clearance, tariffs and shipping?

Freight, duties and customs responsibilities depend on the agreed delivery terms. Ask for these costs to be itemized in the quote.

What is included in your DFM review?

A DFM review can check wall thickness, bend geometry, draft, tolerances and material availability. The scope depends on the part and process.

Which inspection records can be supplied?

Specify the critical dimensions, acceptance criteria and documents needed. Inspection methods and reports should be agreed before production.

How long does a typical project take?

Timing depends on drawing readiness, process, tooling, quantity and delivery route. Request a schedule with the quotation.

Request a quote
