You have decided to automate inspection. The next decision is harder: which machine, built around what? For screws, bolts and nuts, the wrong choice rarely fails loudly. It fails quietly — in false rejects, missed defects and changeovers that eat your week. Work through these points before you sign anything. Define Your Inspection Requirements Start…
In short: Screw thread defects can be inspected automatically. A vision system separates screws individually, then passes them through top, side and bottom camera stations with backlight and grazing illumination, so thread presence, thread profile and thread damage become measurable. Defective parts are ejected automatically. FengHang’s rotary disc platform inspects up to 1,500 pcs/min, with…
Somewhere between the thread roller and the export box sits your biggest quality risk: the parts nobody checks. If your team still samples batches by hand, you already know the math doesn’t work — no one can eye-check 100% of production at line speed. This guide explains how automated fastener inspection closes that gap: what…
In short: Fastener vision inspection equipment is built by two kinds of supplier — specialists who engineer their platforms around screw, nut and rivet geometry, and general machine-vision integrators who adapt a standard cell. The table below lists eight manufacturers that publish fastener-specific vision sorting machines, together with the specifications each company states on its…
In short: Choosing a vision sorting machine supplier in China comes down to five things you can verify before you pay: free sample testing on your own parts, real defect images instead of product renders, cameras configured to your part geometry, integration with the line you already run, and a documented after-sales process. FengHang Intelligent…
If you’re sourcing a vision sorting machine right now, you’ve probably noticed something: the spec sheets all look the same. ±0.005mm detection accuracy. 99.99% sorting accuracy. 2,500 pcs/min. You’ll find these numbers on almost every supplier’s website — including ours. So if everyone publishes the same specifications, how do you actually tell suppliers apart? The…
The single most important step before buying a vision inspection machine is the sample evaluation. Send the right samples, and you get an accurate detection report that forms the basis of your purchase decision. Send the wrong samples, and you get a report that looks good but does not reflect your real production. Here is…
