Test your actual parts as they will be used in the real world. Quantify the complete mechanical performance including the combined effects of materials, processing, assembly, and design.
FinalTest is our comprehensive approach to mechanical testing performed on finished parts and assembled components—not just raw material coupons. This real-world testing methodology captures the complete story of how your product will perform, accounting for material properties, processing variables, assembly methods, and design geometry all together.
Unlike standard mechanical tests that evaluate generic specimens, FinalTest examines your actual parts under conditions that simulate their intended use. This provides invaluable insights that material datasheets and coupon testing simply cannot reveal.
The FinalTest Advantage: Material properties are only part of the equation. Processing conditions, assembly techniques, part geometry, and stress concentrations all dramatically affect final performance. FinalTest captures all of these variables in a single, meaningful measurement.
Test the actual part, not a generic specimen. Capture the effects of ribs, bosses, gate locations, weld lines, and assembly methods.
Measure complete deformation behavior as a function of applied force, revealing stiffness, yield point, and ultimate strength.
Isolate the impact of materials, additives, processing parameters, and post-assembly operations on mechanical performance.
Compare parts molded under different conditions to identify optimal injection molding parameters for your specific design.
When parts are joined via ultrasonic welding, laser welding, or adhesive bonding, FinalTest quantifies the actual bond strength achieved. Compare different welding parameters, adhesive types, or surface preparations to optimize your assembly process. Identify the weakest link in your assembly and ensure it meets performance requirements before production ramp-up.
Molding conditions dramatically affect part performance through their influence on molecular orientation, crystallinity, and residual stress. FinalTest allows you to compare parts molded with different barrel temperatures, injection speeds, pack pressures, and cooling times. We've used this approach to determine optimum injection molding parameters for caps, housings, and structural components—ensuring maximum stiffness and strength while minimizing cycle time and defect rates.
Evaluating a material change or formulation modification? FinalTest on actual parts reveals whether the new material performs equivalently to the current material in your specific application. This is far more reliable than comparing generic datasheet values, as it accounts for how the material processes in your mold and performs in your design.
Before committing to production tooling, validate that your design can withstand expected loads with appropriate safety factors. When parts fail in the field or during qualification testing, FinalTest helps identify whether the root cause is material selection, processing conditions, assembly quality, or design weaknesses.
Establish baseline mechanical performance for your parts and use FinalTest as a periodic quality check. Detect changes in material quality, processing drift, or assembly issues before they result in field failures or customer complaints.
How does your product stack up mechanically against the competition? FinalTest of competitor parts reveals their performance characteristics and can guide improvements to your own design, material selection, or manufacturing processes.
A manufacturer needed to select the best bonding method for filter assemblies. We performed FinalTest on filters joined by ultrasonic welding, laser welding, and adhesive bonding. The force-deflection data revealed that ultrasonic welding provided superior bond strength with less variability, allowing the customer to confidently select this process and optimize welding parameters for maximum reliability.
A customer experienced inconsistent snap-fit performance in molded caps. By testing caps produced under various molding conditions, we identified that higher pack pressure and optimized gate location significantly increased stiffness and reduced warpage. The resulting process changes eliminated field failures and improved assembly line efficiency.
We design and fabricate custom fixtures to test your parts exactly as they're used in the real world, capturing true functional performance.
Our team's decades of experience in injection molding, extrusion, and assembly means we understand how processing affects performance and can recommend improvements.
We combine FinalTest with material characterization (DSC, TGA, FTIR) and process analysis to identify root causes and implement effective solutions.
We don't just hand you force-deflection curves. We interpret the data, explain what it means for your application, and recommend specific corrective actions.
