FOOD INDUSTRY: CASE STUDY
"When an idea was pitched in one of our meetings, I had to look for a rubber manufacturer who could work with us, not against us from a simple drawing.

J Coker came highly recommended from multiple sources and from that drawing through to production, they have helped, guided and supplied us a top quality product.
With a common-sense approach but professional finish, I cannot recommend the services of this company enough and that is hard to find these days.
Thank you, well done and I look forward to our partnership growing in the future."
