Testimonials

“Having worked closely with PEP over the last year across a number of highly complex injection moulding projects, I can say their service has been nothing short of world class. The high attention to detail provided at the DFM stage has helped ensure the most effective design solution is always reached, leading to near perfect, first off tool T0 parts! No problem is too big for PEP and the precision tools I have seen designed so far have been highly impressive.” Technical Director, Construction Industry
"PEP have a very supportive and exceptionally responsive sales and tech team who helped us design our product and get it approved by a certifying authority within our project schedule. It’s been a pleasant co-operation." Procurement & Supply Chain Manager, Medical Industry
"PEP is not afraid to try new things and that includes offering post-moulding processes such as part marking and sub-assemblies. The amount of capability that PEP can offer is impressive to see, especially for a London based manufacturer. I know that I will continue coming back to PEP for my injection moulding needs as they are reliable, easy to work with and strive to offer high-quality services." Mechanical Engineer, Automotive Industry
