ASG - How to Qualify, Quantify and Maximize Your Assembly Application
Our thanks to ASG for allowing us to reprint the following article.

Maximizing the fastening process by implementing an error-proofing strategy reduces costs, increases throughput and minimizes assembly errors. Typically, the process of final assembly is the last to be error-proofed. Attention is given to all of the preliminary operations first such as machining, molding, painting. The process of assembling all the pieces together is usually not given the detailed attention that the previous operations have received.


Potential bottlenecks or assembly flow process challenges can be costly if left uncorrected. These problems can include improper installation of fasteners (screws, nuts and rivets). When this problem occurs, loose or missing fasteners can result in product failures.


The question arises… How do you prevent these problems? The answer is to incorporate error-proofing equipment into your assembly processes. This could be defined as the ability to prevent an error or to detect the challenge prior to the next operations in the assembly process being implemented.


Implementing a process control device could have five general results:

  • Install the fastener in the correct location
  • Drive the fastener to the correct depth
  • Minimize the number of equipment products needed to be used for the fastener installation
  • Provide data collection
  • Operator feedback for immediate resolution to improperly installed fasteners...
