PRETREATMENT, SURFACE PREPARATION, DEGREASING & CLEANING

Semi-and fully automatic centrifuges

The semi-automatic centrifuge is used for the pre-treatment of aluminium components and is handling very contaminated liquids. The insertable basket containing the sludge separated from the liquid is manually exchanged and emptied once per day. This work is done without having to interrupt production. The fully automatic centrifuge for pre-treating steel components is connected to two tanks containing pre-treatment liquid. The centrifuge cleans the liquid from one tank at a time. Switching from one to the other tank is handled by a special valve. The fully automatic centrifuge removes the sludge from the drum wall automatically and dumps it into a large, mobile container that must only be emptied once a month. Norbert Becking explains: “Rösler helped us in organising the switch from one tank to the other. The compact machine is easy to operate. Twice a year it is thoroughly checked by Rösler and, therefore, demands very little attention by our technical department.”

Zero scrap parts, higher productivity and less environmental pollution

Both centrifuges have been in operation for over a year. And both investments have been a win for Ulamo. The spray nozzles are not plugged up anymore and must, therefore, not be checked and replaced so frequently. The pretreatment liquids must only be replaced once a year instead of three times before. Because of the substantially more stable quality of the liquids fewer chemicals must be added. And finally, the employees became free to perform other, more productive tasks. Overall Ulamo is highly satisfied with the centrifuges.

Simon Wagenaar concludes: “In a few years we want to replace the tanks in our production line. On this occasion we will replace the semi-automatic centrifuge with a fully automatic unit. Moreover, we plan to expand our production capacity with an additional line. For this project we will again use the products and service from Rösler.” www.rosler.com, www.ulamo.nl
