®ROLLWASCHbarrelling & vibrofinishing since 1950 !

®Who is ROLLWASCH and what’s its main activity field ?

Rollwasch Italiana S.p.a. is a company founded by Mr. Giuseppe Redaelli in Milan in 1950. From then on we produce and sell machines and products for mass metal finishing. Combining the right type of machines and products (finishing media and/or chemical compounds) it is possible to develop several mass metal finishing processes. In the field specific language these processes are named barrelling or vibrofinishing or also tumbling (rumbling) processes. However you name them, these processes are based on the concept of finishing a mass of parts, generally loaded in bulk as loose pieces into the most suitable finishing machine. The pieces to be finished can be of different materials with shapes and volumes going from a roller-pen ball to a boat mould!

Thanks to our incredible experience developed in several fields (mainly industrial ones) today we are able to provide all sorts of surface finishing processes, from deburring or removal of fabrication polluting residuals, to surface smoothing, mirror polishing,

shading, preparation before painting or plating, ageing of marble and metals as well as other materials, materials washing and cleaning with recycling-aim (environment), cutlery washing (catering field), silverware bright-polishing (hotel industry), and many others...Today Rollwasch Italiana S.p.a. is a company dealing at international levels, with a staff team of approx. 70 persons and three main units (machinery and systems production unit; abrasives and chemical compounds production unit; logistic, warehouse and distribution unit); with an overall units surface of approx. 20.000 sqm. Approx. 10.000 sqm of the total surface has been conceived as sheltered areas.The company head quarter is in Albiate that is located abt. 30 km. to the north of Milan. Here you can find also tests-laboratory, offices and warehouse. The machinery production department can rely on a subcontractors-network of abt. 300 units, which have been selected in decennia of experience. Also this reliable network is contributing to the high standards of quality and reliability of the achieved results and this in a very flexible and competitive way. The chemical facility is a fully automatized factory managed in compliance to ISO-9001 Vision 2000 standards. The whole Company fully belongs to the Redaelli Family. The sales network is managed by Company's specialists coordinating and cooperating with both domestic and foreign agents and distributors. As from the beginning of years '90 the plants production department has developed a complete programme of waste-water treating systems and plants.

Which is the right approach to reachthe best performance ?

1. Define the problem2. Quantify the problem throughput3. Identify the target4. Define the operative methods

Mass metal finishing problems have a high heterogeneity level and a variety, which often depend on specific manufacturing systems and methods, different sales markets and different design requirements. This has brought the company Rollwasch® to deal with each project as it was a single and unique one, thus granting an extreme professionalism. The first step to get the best possible solution for each problem is the finishing process

trial, which is a free of charge test allowing identifying the first solution elements as (f.i.): the batch volumes, the processing times, the compounds and their dosage, the recommendable finishing media, etc. Furthermore this working method offers several additional and parallel advantages like “tangible” results to be evaluated, the opportunity to offer an overall budget and to study also the environmental solutions (noise deadening, waste-water treatments, ergonomics) where needed. All this in a confidential and specific way, absolutely custom made. For an evaluation of your problem it is therefore enough to send us an e-mail, a fax or to call us - we will be glad to let you have all the instructions in order to take all the necessary steps to have your process trial.

In other words, specific dryingsolutions at 360° degrees

Our vibratory dryers of the SICOR series with absorbing grit are also available in the full-automatic version and with special hardwearing linings - our hot-air drying tunnels of the DRYTUN series are also available equipped with screw conveyor, and in the wash-dry combined version.

Rollturbo disc finishing machines for centrifugal force barrelling

The Rollturbo machine series is divided in two separate programmes: the series named HI-TECH is considered as the top of this machines type thanks to its high level of integrated automation; the series named BASIC offers a good solutions range of semi-automatic and basic models for wet finishing processes.

RDF disc finishing machines for DRY or WET centrifugal barrelling

The RDF (Rollwasch Disc Finishing) series differs from the classic Rollturbo series for the reduced capacity of the machines (from 70 to 8 lts.) and for the possibility to effect either DRY or WET processes.

Thanks to the "Diamond Microgap" solution the RDF series can treat very thin articles. Thanks finally to some specific adjustments made on this extremely "technical" series it is really possible to adopt highly innovative finishing techniques.
