Automatic Marking Cell for Bolts
Our customer required permanent, unique identification marks on a series of bolts and fasteners for aerospace applications.
The system needed to automatically feed and serialise a wide variety of dimensions and designs of bolts and ensure that they were 100% marked on the top surface.
The solution features a bowl feed mechanism with variable settings for aligning and feeding different dimensions of fastener. The marking system as been built around a standard Pryor BenchDot marking systems, which is ideal for low stress, aerospace marking applications.
The control system is the latest generation of Pryor embedded controllers, with easy to use and configure operator interface via our Traceability Software.
What is Bolt Head & Fastener Marking
Bolt head markings are symbols or imprints on the top of a bolt, conveying crucial information about its properties and specifications. These markings include grade indicators, denoting the bolt’s strength, often represented by numerical values or symbols. Material markings indicate the bolt’s composition, such as stainless steel.
Some bolts bear manufacturer logos or names. Metric bolts may display a property class indicating tensile strength and yield strength ratios. Additionally, thread size and pitch information might be stamped on the bolt head.
Interpretation of these markings is subject to regional and standards organization variations, requiring reference to specific standards (e.g., ISO, ASTM, DIN) or manufacturer documentation for accurate understanding.
“A fully automated marking system which can be quickly loaded with a larger volume of bolts and then left to run with 100% reliability is a huge asset for our customers production process.”
