Sub Contract Engineering

We have been providing high quality engineering services to our clients for over 25 years. With modern facilities and a skilled team, we can produce high precision components in various materials. We specialise in one-off prototypes and relatively small batch quantities.

We have experience in the design and manufacture of mechanisms for the oil and gas industry as well as varying optical systems for the Future Metrology Hub, based at the University of Huddersfield. Other projects have included refurbishments or new mechanisms for large external clocks.
