Rubber duckbill valve manufacturers
RONCAGLIA (R) has a laboratory, where the rubber compounds undergo physical and chemical analysis to confirm that they meet all conditions before being used in the productive sectors of the Company. Degree of hardness, elongation, abrasion resistance, chemical resistance to various products, an aging, placing some of the controls are being performed.
It is also important to note that, in addition to submitting to control all the compounds that are sent to production, the laboratory develops new formulations for new needs, and primarily in response to the policy of continual improvement, which characterizes RONCAGLIA (R).
The laboratory has a rehómetro, oven aging, abrasion tester, tape measure and dynamometer.
It represents a fundamental contribution to the work mancomuncado INTI - Rubber current name of the Center for Research and Technological Development of the Rubber Industry, which Juan Roncaglia SAIC is a founding member. In this Institute, Roncaglia carries out tests to contrast the results of his laboratory with the Institute Oficial.Esto doubly ensures the results beyond the calibration to be detected in only all elements of control.
The most important steel manufacture argentine company has employed the RONCAGLIA® SLEEVE for steel sheets coils winder and de-winder mandrels, since more than 30 years in his five plants.
The use of this rubber sleeve, allows:
1-to protect the steel sheet, the defects caused by the metallic mandrel, on the first loops. When a metallic mandrel is opened against the thin metallic sheets, usually a typical mark has been place, on the first loops, these loops have been rejected.
2-to replace metallic supplements for different I.D. coils. When it is necessary to produce coils with different internal diameters, the use of Roncaglia® rubber sleeve, instead of such heavy’s metallic supplements, assures faster and safer installation.
3-to protect mechanical mandrel systems. When you use Roncaglia® rubber sleeve, you have an additional advantage; you are protecting the mandrel mechanisms from dust, which can affect the normal operation.
