Why PIP is the best alternative to Tensile Testing

The Indentation Plastometer is a benchtop mechanical testing technology that requires no coupons to be machined prior to testing. The result is a test that is 80X faster and 90% cheaper than tensile testing. The Plastometer also allows for small samples to be tested and for property variations to be mapped.

80X Faster + 90% Cheaper* than Tensile Testing

The average turnaround time for a tensile test result is about 5 working days (40 working hours). As well as being slow, the classic tensile test is also expensive, with a typical cost per test in the region of £40 ($50).
The Indentation Plastometer requires no “dog-bone” coupons to be machined prior to testing. It only requires a flat and relatively smooth surface for indentation. As a result of this, the test typically takes 25 minutes (predominantly preparation with test times of up to 5 minutes) and costs approximately £4 ($5).
These dramatic time and cost savings support healthy cash flow, free-up resources to be allocated elsewhere, and increase the efficiency and predictability of technical project delivery.

Test Small Volumes and Complex Parts

While the Indentation Plastometer offers unparalleled testing efficiency, it also unlocks greater testing versatility when compared to tensile testing. The Plastometer deploys an indentation based test method, with an indenter tip on the order of 1-2 mm in diameter. This enables users to measure stress-strain curves from small, complex, or heterogeneous parts - removing the need to rely on sub-standard data sets, conversions, or unsafe assumptions.
Specifically, the technology reduces the material volumes required for testing by 99% when compared to the most common tensile test procedures. The system can also carry out an array of indents across a single part to quantify any spatial property variations.,
