The sample checked out. The production run may say no — because the sample came off by hand, from the careful people, on the shop’s best day. So a first article inspection (FAI) exists to close that gap. It delivers the controlled, recorded proof that the production proce

Every fabrication quote hides four assumptions, and the material is the first one that fails silently: a grade substituted at the mill, a temper that changes the bend math, a “stainless” that is not the stainless you specified. So metal material selection deserves i

First, the right fabrication route is not the best machine. Instead, it is the intersection of four answers you already have: how many, what shape, how precise, and what budget. Ask those four questions in order, and the metal fabrication processes that survive narrow themselve

Every fabricated part lives on two calendars at once: the quantity calendar (how many pieces the process will economically run) and the time calendar (when the pieces can exist). Buyers ask about the two separately, but the answers are coupled. The process with the lowest metal

First, the total on the quote is the last number you should analyze. It sums decisions you have not seen yet, and metal fabrication cost only becomes clear once you open the structure. This guide works backward from the total: the four decisions that set the price, the three mo

Sheet metal tolerances are never one number for a whole part. Laser cutting holds about +/-0.1 mm on standard sheet thicknesses, and CNC machined features typically hold +/-0.02 to 0.05 mm. Press-brake bending usually stays within +/-1 degree, whereas stamped dimensions depend

Short answer: China metal stamping is not one market. It splits into regional clusters, and each cluster grew up around a different customer base. Precision electronics stamping concentrates in the Pearl River Delta and the Yangtze River Delta. Automotive stamping and die-makin

Short answer: At 100,000 pieces a year, a China metal parts manufacturer is no longer quoting parts — you are qualifying a production system. Evaluate the supplier on four things in this order: a documented qualification sequence, first article and capability evidence on your a

Short answer: For recurring production volumes, a China-based metal stamping factory with in-house tooling usually wins on unit cost and process control. Meanwhile, US on-demand fabrication services win on speed, zero tooling investment and domestic logistics. Thus, the right c

Direct answer: To verify a metal-stamping supplier in China, review evidence across equipment, actual process coverage, inspection controls, and the legal or operating entity information shown in supplier documents. Use a drawing-based inquiry and stated checks rather than rely
