We will work with you to solve your Surface Engineering challenges to enhance performance, productivity and profitability:

Wallwork Cambridge's friendly and talented team of seven highly qualified and experienced R&D Engineers and Scientists carry out high quality research and development at the leading edge of science often resulting in publications in the scientific literature, patents and of course new products for our customers. R&D staff present scientific papers at conferences worldwide.

List of publications

Applications development

To match coatings to the particular demands of specific applications.

We develop new coatings and surface treatments from conception through to production.

Collaborative R&D projects carried out working closely with customers to achieve their goals.

New coatings development

Ensures Wallwork Cambridge remains at the leading edge of Surface Engineering with state of the art coatings to meet our customers' needs.

New process development

New coatings often call for new processes, sometimes requiring equipment modifications or new equipment builds. Working closely with our Engineering/machine build department and Universities from around the world we have all the skills and experience we need to come up with the solution on an industrial scale.

R&D projects on a wide range of timescales

Wallwork Cambridge customers come from all types of industry; from food to offshore, automotive, aerospace, general manufacturing, biomedical, pharmaceutical and many more. We're ready and able to discuss and resolve problems with scientists and engineers from any and all industries.

Experienced in project management and leadership

Good track record in leading the writing of successful project proposals winning grant funding and leading multi-partner collaborative R&D projects.

Wallwork Cambridge manages research projects with industrial companies and research establishments/universities in many countries, often co-funded by UK or EU government and industry.
