De Mattia Flexing Machine
The Wallace DeMattia F16 flexing machine is designed to test the resistance of rubber materials to cracking and cut growth caused by repeated flexing. It is commonly used for evaluating products such as tyre sidewalls, shoe soles, seals, belts, and other elastomer components subjected to cyclic stress.
- Product Name
F16 De Mattia Flexing Machine
- Overview
The F16 includes a range of 3 models capable of handling 12, 24 or 36 samples in an oven with digital temperature controls ranging from ambient to 150°C. Easy access cabinet or oven versions available, all with 9-999,999 cycles allowed per test. Motor cut outs fitted to both doors to ensure operator safety.
- Standards
ISO 132, ASTM D430-06, ASTM D813
- Application
To test specially moulded samples for resistance to cracking or cut growth by repeated flexing in either a heated or ambient environment.
- Calibration Options
Manufacturer Calibration Certificate included as standard
- Typical Lead Time
6-8 weeks (to be confirmed at time of quoting)

Cracking and cut growth increase with increasing cycles. Samples are loaded so that they are flat when the grips are tightened and flexed but not elongated during tester operation.
The tester is stopped at intervals specified and the cracks evaluated. Two sets of grips on either side of the frame are reciprocated at constant frequency for a pre-set number of cycles controlled by a cycle counter.
Easy access to the interior of all machines is provided through hinged front and rear doors. Four recessed lamps provide interior illumination, and a knurled flywheel is used to rotate the mechanism, and a brake to hold the position for easy sample loading. The main shaft is fitted with a balance weight to ensure smooth running.
-
The machine is primarily designed for rubber and elastomer compounds using specially moulded test specimens prepared according to recognised test standards. You can find suitable moulds here.
-
Crack initiation testing determines how long it takes for a crack to first appear, while crack growth testing measures how quickly a pre-existing crack propagates under repeated flexing
-
Yes, look at the moulds in Specimen Preparation section or you can contact us and quote Part Number WAF1/1 for 3 cavity specimen mould, WAF1/1/1 for 6 cavity specimen mould.
-
Yes. The machine includes motor cut-outs on both doors, internal illumination for visibility, and a balanced main shaft for smooth and safe operation.
-
Yes. The F16 is suitable for both routine production quality control and advanced research and development applications involving rubber and elastomer durability testing.
-
Available accessories include:
- Three-cavity specimen moulds (quote part number F1/1)
- Six-cavity specimen moulds (quote part number F1/1/1)
- Piercing tools for initiating controlled crack growth (quote part number F1/3 and specify the BS, ASTM & SATRA required)
These accessories help prepare specimens in accordance with international standards.
-
The choice depends primarily on sample throughput, testing frequency, and laboratory capacity requirements. Higher-capacity models improve productivity when running multiple compounds or formulations.
-
Yes, provided each specimen is correctly identified and all samples are tested under the same environmental conditions.
-
Yes. The oven version provides temperature control up to 150°C for accelerated flex fatigue testing.
-
The oven version offers temperature stability of approximately ±1°C to support consistent and repeatable results
-
Samples are mounted in four banks and secured between grips. The balanced mechanism and flywheel facilitate easy loading and positioning.
-
A bespoke stand can be provided on request. Please contact us for further information.
