Coproget Company

COPROGET S.r.l. is a well known company operating in the field of the design and construction of prototype and manufacturing equipment for the cold processing of sheet metal: roll forming lines, bending and/or stretch forming machines, progressive dies, transfer dies, dies for panels. Its ability to produce efficient and functional production plants is the result of long experience in the production of prototypes. Since 1994 it has constantly expanded in terms of type of production and of quality and services supplied to Clients. A genuine passion in its daily work and top level professional training of its personnel have enabled COPROGET S.r.l. to satisfy successfully the needs of the most demanding markets.
The continuous exchange with the Clients and the satisfaction of their needs are behind its expansion, also sustained by continual investments and constant staff training. COPROGET S.r.l. is able to ensure excellent product management from the beginning to the end of the production phase: design and development of the product using CAE/CAD/CAM systems in CO-DESIGN; design of equipment and automations construction of equipment and automations; performing control procedures in internal laboratory; collaboration with reliable and qualified suppliers; highly flexible response; compliance with safety and quality norms regulations.

Vessels stress test

A Von Mises stress test procedure has been adopted to check vessel resistsnce to pressure force.



Roll Forming

Roll forming, also spelled rollforming, is a continuous bending operation in which a long strip of sheet metal (typically coiled steel) is passed through sets of rolls mounted on consecutive stands, each set performing only an incremental part of the bend, until the desired cross-section profile is obtained. Roll forming is ideal for producing constant-profile parts with long lengths and in large quantities.

Coproget manufactures roll forming machines, uncoilers, decoilers, roll form dies and presses for the roll forming industry. An entire line can be automated with rapid change features to switch from one profile to another at the push of a button, and all of our roll formers come with plug and play features for easy and quick installation! We also provide coil processing machines, including blanking lines, cut to length lines, slitting lines, and components.

Code calculation

One important component of the standards for pressure vessels is the use of a safety factor. The measured physical properties of a material, including ultimatetensile strength, are divided by a defined safety factor to derive the maximumallowable stress. In this way, allowance is made for limitations in the testingtechnology, unusual stress concentrations, non-uniform materials, and materialflaws. Technological improvements, especially in materials testing, have allowed areduction in the safety factor to 3.5 in current editions of Section I; this is thesame factor used in Sections VIII-1 and VIII-2
