GTMA is a UK-based engineering trade association accredited to ISO 9001:2015 and working towards ISO 27001:2013 Data Management. GTMA represents leading companies in precision engineering, toolmaking, additive manufacturing,
metrology and tooling technologies.

We embrace technology, procurement and supply chain initiatives to offer solutions across a full range of business needs. We have a committed strategy to focus on major market sector opportunities, from aerospace and automotive to medical and marine.

Our work with OEMs and Tier 1s has seen in recent years a significant number of manufacturers who use the GTMA website to source suppliers or use our procurement service. This service provides a free of charge individual sourcing service through our Manufacturing Resource Centre which is specifically dedicated to providing supply chain solutions.


Over the last few years GTMA has been involved in providing a route for sourcing engineering companies for the manufacturing supply chain. Building on the ground work achieved through our website we now can reach over 17,000 identified manufacturers who have visited our website and this number will grow substantially as we move forward.

Though this is only about 15% of the total visitors it provides an ongoing connection with manufacturing companies and sectors in which our industry is involved. We believe that this is a very powerful tool and puts the GTMA in the driving seat to set up Cluster Groups to strengthen the Supply Chain and identify the ‘lost SME engineering skills’ not visible to the OEMs.
