Optical Sorting Machine for Fasteners: A Buyer's Guide

What a Fastener Sorting Machine Checks Fastener inspection covers dimensional checks (length, width, height, ID and OD) and appearance checks such as short shots, pits, cracks, burrs, scratches, discoloration and material mixing. A standard single table machine handles parts from OD 6 mm to 80 mm and thickness 0.5-40 mm, with equipment customized around your size range.

Camera Count and Defect Coverage One to sixteen cameras perform full appearance and dimensional inspection on a 650 mm or 800 mm glass turntable. A typical nut or washer line needs fewer cameras; threaded inserts and multi-feature parts benefit from more views per part.

Throughput Expectations Throughput runs 120-840 pieces per minute depending on product size, actual feeding and camera count. Vibratory bowl and elevator feeding cover most fastener shapes; centrifugal disk feeding suits round parts, and mechanical arm feeding protects plated or delicate finishes.

Accuracy and Verification Standard single and dual table sorters repeat at +/- 0.01 mm, while high-throughput double-layer platforms repeat at +/- 0.02 mm - check the model page for your part family. If your tolerance is tighter, one-click measuring instruments with telecentric lenses repeat at 0.005-0.01 mm depending on model (HZXX-JC07 desktop 0.005 mm, HZXX-JC08 bench 0.01 mm) and are used for offline verification of the sorter's decisions.

Materials and Plating Compatibility Vibratory bowls and glass turntables suit bare metal fasteners; for plated, coated or delicate finishes, discuss handling options with our engineers so the feeding path does not mark the surface. Confirm material mixing detection if your line runs several fastener materials together.

Getting Started Send your fastener samples and the defect list you must catch. Shengyi New Material (Huzhou) Co., Ltd. will size the machine, propose the feeding system and camera count, and run a sample inspection on your parts before you commit to production.
