Mandrel Break Load Testing for Blind Rivets
Rivmate offers mandrel break load testing for mandrel-type rivets to verify that the mandrel breaks consistently within the correct tensile force range. We can help you reduce the risks of premature mandrel breakage, failure to break, incomplete riveting, and assembly instability before placing bulk orders.
Why Mandrel Break Load Testing Matters for Blind Rivets
The mandrel break load of a mandrel-break rivet directly affects the stability of the riveting process.
If the mandrel break load is too low, the mandrel may break prematurely, resulting in the rivet not forming completely. If the mandrel break load is too high, the riveting tool may be unable to break the mandrel smoothly, affecting assembly efficiency and potentially damaging the tool or workpiece.
A stable mandrel break load can help you reduce line stoppages, rework, and quality complaints.
Equipment Used for Mandrel Break Load Testing
Rivmate is equipped with a professional rivet performance testing laboratory capable of conducting mandrel break load testing, tensile strength testing, shear strength testing, rivet core retention testing, pull-out force testing, and batch consistency testing on mandrel-drawn rivets.
Universal Testing Machine
Apply a constant tensile force to the pin core and record the fracture force value
Test Fixture for Pin Core Break Strength
Secure the rivets and rivet cores to ensure stability in the direction of force
Standard Data Acquisition System
Records maximum tensile strength, curves, and test data. Also supports report generation.
What Mandrel Break Load Data Can You Get?
Rivmate does more than just provide a simple pass/fail determination.
We can record complete mandrel break load test data according to your needs, including maximum break load, average break load, minimum and maximum values, fracture location, fracture condition, test curves, and batch information.
This data can be used for:
- Sample verification
- Pre-purchase validation
- Matching with automated riveting equipment
- Supplier evaluation
- Internal engineering audits
- Custom rivet development
- Batch quality traceability
