Cocio - Efieciency and economy are paramount


"We now change gaskets for pistons 2-3 times a year, and we have been using the same pistons for 4 years now. We have had a great economic advantage with this solution and can highly recommend Alfotech’s hard metal coating," says Technical Manager, Bo Boesen.

Cocio Chokolademælk uses hard metal coating

In 2002, Cocio Chokolademælk A/S opened a brand new factory. The production equipment is new and highly automated on the two flexible lines. One can run well over 30,000 bottles per hour, and this places great demands on the mechanical wear parts.

”For the past 9 years, we have had a good co-operation with Alfotech. Be it on both hoses and hard metal coated parts. At Cocio, we found that on our Homogenisers in the dairy we had increasing and persistent gasket changes on pistons on a weekly basis. Likewise, we had piston changes twice a year.

By agreement with Alfotech, we renovated our worn pistons with hard metal coating. This has shown a marked improvement regarding replacement of parts. We now change gaskets for pistons 2-3 times a year, and we have been using the same pistons for 4 years now. We had a great financial advantage with this solution and can highly recommend Alfotech’s hard metal coating," says Technical Manager, Bo Boesen.

All pistons for homogenisers, which were originally hard chrome-plated, are now coated with hard metal. Alfotech's coating is made in accordance with ISO 9001 and can be used to advantage on both new and used wear parts such as shafts, seats, pistons, and fitting parts. If the wear part is in direct contact with foods, FDA-approved materials are used.
