Firearms Manufacturing

 

 

Firearms manufacturer can use the Trigger Scan System in multiple areas.

Customer Service

The manufacturer of target or hunting firearms can supply a printed trigger profile together with the rifle or pistol. In this way it is not only documented in what state the trigger of this particular firearm was, when it was delivered. It is also demonstrated, that your company is using the most scientific tools to ensure a proper quality control of the used components.

 

Quality Control

For the production quality control is the main issue. With a maximum duration of 15 seconds for the test cycle of the complete trigger characteristic, a random or complete control of the produced firearms can be done in a cost-efficient way.

The data can be stored and retrieved if necessary. Statistics for the analysis of the production can be one application. Inquiries of a complaining customer can be checked as well as it could be an advantage in the case of product liability, if one can show evidence that the trigger pull was not below or above the production standards.

 

Research & Development The development of trigger systems requires more than the knowledge of the maximum force. The full graph of a trigger characteristic is important. Up till now this could only be checked by feeling with the finger, a usable but not very scientific method. The Trigger Scan system will not only give the force versus travel graph, the system will also analyze the energy put in the trigger to release the firing pin. In a double action trigger the ignition energy is put into the system via the trigger pull. Therefor the energy to actuate the trigger - minus the friction - gives an information about the ignition energy and possible causes for light strikes on the primer.
 

Measurement of an S&W Revolver shows that 415 Nmm of energy is needed to actuate the trigger. This energy is consumed by compression of the springs and friction of the internal parts. For this revolver, the energy distribution is apparent from the graph.

Part Energy in Nmm Energy in %
Rebound Spring
101,3 N mm
24,4 %
Cylinder
16,6 N mm
4,0 %
Hammer Spring
292,0 N mm
70,2 %
Safety bar
5,9 N mm
1,4 %

 

Spring Test

A further advantage is the possibility to test the properties of springs delivered from a supplier. Springs are one of the most critical parts in firearms and the spring constant has a great influence on the reliability and the performance of the finished product. A delivery of springs can be checked in a matter of minutes and a lot that exceeds the tolerances can be rejected. A supplier who knows that his springs can be tested in a scientific way will strive harder to stay within the given tolerance and therefore deliver a better product.

Testing a spring is a matter of seconds with this tool.
