the quintus technology
High-quality flexform sheet metal forming in low volume production runs
Producing pressed sheet metal parts with Quintus technology gives your parts the same characteristics as with regular hydraulic pressing or press hardening, but is usually more cost-effective. You get greater freedom of design, stronger parts and can often avoid the need for subsequent machining. Taken together, it makes Quintus the optimum technology for the production of prototypes, pre-series and low volume parts manufacture.
When we at Jobro are contacted by a company or designer who needs help with a new prototype, we always consider a pre-series using the Quintus technology. The reason for this is simple. In comparative terms, the initial investment is much smaller. Using a Quintus press, only one tool half is used. In many cases, the same tool half can then be reused in the hydraulic press if the product is to continue into higher volume production.
The Quintus press technology involves pressurising castor oil against a rubber membrane which is pressed against the sheet metal on top of the tool. The press force can be varied up to a pressure of more than 90,000 tonnes, equivalent to the kerb weight of 60,000 cars of normal size.
Under such a high pressure, the rubber membrane acts more or less like a layer of viscous fluid. It makes it possible to achieve complex part geometries. The tool can also have some undercuts added. What can be achieved using the Quintus technology is determined more by the physical characteristics of the metal than by any limitation in the press technology itself.
Flexform sheet metal forming with a Quintus press is ideal for:
- Low volume production runs
- Mules and prototypes
- Parts with special surface requirements
- Sheet metal components with (small) undercuts
- Parts with intricate shapes
- Flexibility in the metal thickness, 0.3–10.00 mm in the same tool
