Rubber Technical

From simple stress calculations, through to vibration analysis or complete fatigue life design, Derwent are leaders in all types of rubber design.

Design & Application

Tooling, Material Selection and Design Component

From simple stress calculations, through to vibration analysis or complete fatigue life design, Mackay are leaders in all types of rubber design. With over a quarter of a century of expertise in finite element analysis, we can find the right solution to your problem whether it’s off the shelf or a completely new design.

Raw Materials

Collaborating with Suppliers for the Highest Quality Materials

Whether it’s raw polymer, chemical additives, standard or exotic metals, Mackay work hand in hand with our suppliers to ensure the highest quality materials are available throughout our manufacturing processes.

Compounding

Our team of experienced chemists can provide customised rubber formulations tailored to your application.  After decades of developing products for defence, automotive and industrial applications, Mackay can “fine-tune” rubber compounds for a range of applications to optimise properties such as:

Testing

As part of the requirements of our ISO 9001 Quality Systems certification, Mackay performs 100% batch testing on all rubber mixed in our own Mixing facility on site, ensuring we maintain full control of the compound quality used in our products.
All batches are tested using a Rubber Process Analyser, able to test dynamic properties as part of our quality control process, in addition to standard rubber QC tests.
Our laboratory is NATA accredited to AS ISO/IEC 17025:2018 to test the physical properties of rubber for a range of tests.

Test & Verification

Finished part testing ranges from hose burst testing through dynamic vibration testing to 300kN static compression testing.  Initial part testing can include accelerated ageing tests, multi-axis characterization and fatigue testing where appropriate.

Final Inspection

Whether it’s an incoming component or a finished part, Mackay’s metrology department can measure it to make sure it’s right. 3D laser scanning is just one of the many tools used
