• Design & Application

    GMT provide full design and application support. Parts can either be selected from thousands of existing products or else a new bespoke solution can be designed to meet unique customer requirements. In-house Finite Element Analysis can be used to ensure designs are ‘right first time’ thereby reducing the time required to bring new products to full production.

  • Tooling

    GMT design, develop and manufacture vulcanisation mould tooling in-house thereby reducing lead times and ensuring an optimised design for the applications.

  • Raw Rubber

    GMT source from rubber tree plantations around the world ensuring our products achieve the highest quality and consistency.

  • Rubber Compounding

    50 years of experience combined with significant continual investment means that GMT can meet the requirements of our customers even in the harshest of applications and operating environments. Computer controlled automated mixing systems ensure the correct ‘recipe’ is produced from the many thousands that GMT have developed.

  • Calendering / Mixing

    In house rubber mixing and formulation ensure GMT can provide the right rubber at the right price at the right time to optimise the service and quality provided to our customers.

  • 100% Testing of Rubber Batches

    All batches of rubber are controlled and 100% tested prior to being accepted for production. This ensures traceability through to the finished product and also suitability of the rubber batch to meet the customers requirements.

  • Goods Receiving

    GMT’s large and modern goods inwards facilities help ensure an efficient process through our organised storage systems.

  • Metals Inspection

    All parts are inspected according to detailed specifications. Full CMM capability ensures GMT can accurately check goods received prior to accepting them for production.

  • Metal Preparation

    Preparing metals in a specific and controlled way is essential to achieve successful vulcanisation and bond integrity between rubber and metal interfaces. This is normally achieved as a combination of shot blasting and bonding agent application

  • Vulcanisation

    Under tightly controlled conditions and machine parameters unique to each production batch, the vulcanisation of the rubber compound is achieved. This process also produces a strong bond between rubber and metal where applicable. The process is followed by a strictly adhered curing period which is crucial in achieving optimised performance and life of the rubber. With more than 500 transfer, compression and injection moulding machines, GMT have the capacity and expertise to be able to meet the growing demands of our customers.

  • Final Inspection

    Products are inspected and cleaned following vulcanisation. Where necessary, parts may be subject to further machining, stress relieving or coating application for corrosion prevention.

  • Assembly

    Products can be supplied individually or as part of a system or assembly. Where large scale overhaul and replacement of existing product is required it may be possible to reclaim and refurbish the existing metals. This can help reduce lead time and improve sustainability of materials.

  • Test and Verification

    Extensive test facilities allow GMT to perform test and verification procedures on components to confirm performance. Multi-axis dynamic testing can be used to simulate real world combined load cases. Lifetime and residual life tests can also be performed where required.

  • Packing and Despatch

    Following final inspections and testing, parts are suitably packaged to ensure safe, secure and damage free transportation according to any agreed shipping mode.
