Hard metal coating brings several benefits at Cocio.

Improved efficiency & operating economy

Today, Cocio Chokolademælk A/S' modern factory operates with several fully automated production lines that run thousands of bottles per hour every day. Naturally, this places great demands on the wearing parts used in production.

But that wasn't the case in the past. Bo Boesen, Technical Manager at Cocio, says:

"A few years ago, we noticed that the homogenizers in the dairy had increasing and continuous piston seal changes on a weekly basis. Similarly, we had piston changes twice a year. Together with Alfotech, we renovated our worn pistons with hard metal coating. Since then, we have seen a significant improvement in efficiency and better operating economy. We now change piston seals 2-3 times a year and we have been running with the same pistons for 4 years now. We have had a great economic benefit with this solution and highly recommend Alfotech's hard metal coating."

All pistons for homogenizers that were originally hard chrome-plated are now coated with carbide.

Our hard metal coating is carried out according to ISO 9001 and can be used on both new and used wear parts such as shafts, seats, pistons and fittings. If the wear part is in direct contact with food, FDA-approved materials are used.
