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.

JUAN RONCAGLIA SAIC also produce RONCAGLIA(R) rubber sleeves for export to major steel companies all over the world.
ADVANTAGES FOR THE USER
Reject reduction. The level difference at the end of the coiled rolled steel sheet, as well as the metallic mandrel sides, are absorbed by the elastic rubber sleeve. No end marks on the following strip windings.
Shorter set-up time. Very fast change of inner coil diameter. The sleeves can be mounted with working installation. Change the I.D. coil en minutes.
Safer operation. Safer operation comparing to steel heavies reel jaws.
Mandrel protection. Addicional advantage, RONCAGLIA (R) rubber sleeves protects mandrel mechanisms.

In the river transportation of goods by barges, many barges are pushed by one tug. To avoid the constant friction of metals, JUAN RONCAGLIA SAIC produces two types of defenses 1-metal plates with rubber in different sizes to be welded in the front of the tug 2-Multilayered rubber reinforced with textil insertion, fenders. These fenders are employed all over the world for this application.

Roncaglia weld on bumpers are used to protect push tugboats and other structure from damage caused by the constant friction between the tug and barge
Roncaglia produces standard dimentions weld on bumpers, as well as parts according the customer request
All these products are manufactured with high wear and environmetal resistant rubber.
The rubber bonded to steel base plate has a bond stregth higher than the tensile strength of the rubber.
For over 50 years Roncaglia® is engaged in manufacturing rubber products for use in military vehicles. The new wheels are used stickers and it removes the worn rubber material and re-glue ensuring the same durability in both cases. Caterpillars are also made of metal and half-tracks and rubber pads for steel tracks. In the laboratory has developed rubber compounds highly tear resistant and abrasion to which they are subjected military vehicles. Roncaglia® has been involved since its inception in the manufacture of wheels for the historic Sherman, the AMX 13, AMX 15, TAM and Halftrack Diamont T and M 113. This facilitates the fabrication of pieces by its age or modifications made and not on the market.

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.
