Customer report about the purchase of a JUTEC mandrel bending machine

Matthias Weygandt had been toying with the idea of buying his own bending machine for some time. A major order then made the decision easy for the Hessian metal construction engineer.

The purchase of his new bending machine was not a major consideration for Matthias Weygandt. "We got a big order, which already financed the purchase to a large extent," says the metalworker from Darmstadt. The order was the little spark it took to ignite the flame. Weygandt had been toying with the idea of having his own bending machine for some time, and had also decided on a model: a mandrel bending machine from Jutec. "Of course, we have known the manufacturer for some time, for example from trade fairs." At first, the entrepreneur looked around for a used machine, but did not come to an agreement with the seller. Then everything happened very quickly: "I obtained a quote, signed the purchase contract three days later, and after five weeks the machine was there. It went off without a hitch."

Investment and amortization

The machine is a Jutec mandrel bending machine model 5045 and costs around 48,000 euros. That sounds like an impressive sum to spend in just three days. But Matthias Weygandt resolves the investment with a simple rule of three. "In this project, we received an order for more than 1,000 meters of handrail. I calculate that we will save about 2,000 welds. If I assume 20 euros per weld, I already come to 40,000 euros." Of course, you still have to subtract your own working time from this, but for Weygandt it is clear that the expense was worthwhile.

Weygandt financed the purchase in cooperation with his bank. This was the most uncomplicated solution, he says. The manufacturer would also have stood by him, as Meike Berléung from Jutec assures: "We are happy to provide financing offers at the customer's request."
Order processing and application

User report Jutec mandrel bending machine Metal builder - Matthias Weygandt reportsHow order processing at the machine manufacturer works is explained by Meike Berléung: "The customer contacts us with the bending tasks. We prepare an offer for the bending systems in question. Various equipment details are discussed in a personal meeting with a demonstration of the machines at the customer's site or in our training center. The customer orders the machine." The production time for standard machines is about four weeks. Instruction takes place on site at the customer or in the training center - depending on the customer's requirements.

Weygandt Metallbau from Darmstadt has been awarded the contract for a large residential project in the Gallus district of Frankfurt. The residential block houses almost 500 residential units. There are eleven staircases, six floors and also handrails on the individual floors. The major project will employ a good half of Weygandt's workforce over a period of three quarters of a year. Production and assembly will be kept busy for a good part of the time just with this project. But Weygandt is confident that bending will continue to gain acceptance at Weygandt thereafter. "We can now offer services that we didn't have in our product range before." With a bending machine, one approaches orders in a completely different way. Whereas before it was often a matter of avoiding bent tubes, he now has a new freedom of design. He expects to utilize the machine to capacity himself in the future. "Offering contract bending is out of the question for us," Weygandt says. "It makes us much more competitive." Curved handrails, he says, can also be done in a manual instruction. "But not in this precision," Weygandt says.

Bending properties and control

The Jutec machine is considered an economical solution for tight bending radii. The compact drive unit with the detachable mandrel carrier offers great advantages when using other bending systems (roll and profile bending). The free-standing bending head can be quickly converted to right- or left-hand bending for complicated geometries. The plug-in bending tools allow quick changeover to other tube dimensions. With the optimized hydraulics for tube clamping and tool locking, bending quality is significantly improved. The automatic drive allows bending and non-productive times to be significantly reduced.

The robust PLC control with password management and data memory can accommodate 1,000 programs for bend angle, linear dimension and twist angle for a maximum of 50 bend sequences on one tube length. Up to 500 materials can be entered in the database to compensate for springback. Operating errors are displayed directly in full text on the large screen. Operation is convenient via a touch display. Simple and fast data backup is possible via a USB stick. The hydraulic mandrel retraction is programmable and is automatically retracted prematurely when a bending angle is reached. The sheet quality is thus adjusted, and expensive crease smoothers can be dispensed with in most applications.

Service and support

The machine is still in a separate hall that Matthias Weygandt has rented from a neighbor. But that's because Weygandt is planning an expansion anyway. Once this is completed, the machine can then be easily moved to another location. Jutec trained four Weygandt employees - including the managing director himself - in the use of the machine for one day.

Matthias Weygandt considered it very important to have a short line to the service department. With new machines in particular, it can always happen that uncertainties arise in the first few weeks. You can't be left out in the cold. "We naturally maintain contact with the customer after the purchase," says Meike Berléung. "Thus, every customer has his contact person at Jutec, so that standard tools can be supplemented immediately from stock. Specific tasks can be discussed by phone or e-mail. The customer also has the option of coming to our factory at any time." The company is based in Limburg, Hesse. Weygandt, for example, even communicated with his consultant via WhatsApp while he was at a trade show in Russia. "That went very well," praises the Hessian entrepreneur.

Maintenance and retrofitting

The machine has a network connection and can therefore be checked remotely. There are hardly any wear parts, except for the long-life tools, says Weygandt. "The maintenance effort is close to zero." In addition, the machine can also be converted from a mandrel to a three-roll bending machine with a separate setup. However, Weygandt has not yet used this option.

"In terms of diagnostics and Internet of Things, with these machines we have the option of exporting all machine parameters, bending programs and materials, so that an identical machine can then be displayed at Jutec and any desired changes can be made," explains Meike Berléung. "The modified data is then sent back to the customer via e-mail and installed on the machine." ⇥pet ◊
