Laser cutting machine modernizes our cutting process

The website www.metaalnieuws.nl and www.laserbendingmachines.com published a nice article regarding our machinery. The purchase of a laser cutting machine modernizes the cutting process and our machinery. The entire article can be read below:

Vink Products in Katwijk has replaced four plasma cutting machines with one laser cutting machine with an automatic loading system. Three plasma tables have already been disposed of; one machine was left for a while to be on the safe side. But the first few months with the new cutting process have gone so well that the last plasma table could soon be gone as well. “We should have done this 10 years earlier,” said general manager Rob van Duijn.

Vink Products is a manufacturer of metal air ducts and air technology components, such as outdoor air diffusers and roof hoods. These are all produced in-house. Rectangular, round and oval air ducts are produced in different types of metal: galvanized steel, aluminum, stainless steel and plain steel. Vink processes this material in various sheet thicknesses ranging from 0.75 to 5 mm.

A-brand laser cutting machine

Standard utility ductwork was always cut on the four plasma tables. But Vink also makes industrial air ducts, and the cutting work for these was mostly outsourced. With the company’s growth, however, it was time for a new development. Vink actually only processes thin plate, and that made investing in a laser cutting machine interesting. For Van Duijn, there was no question that this had to be an A-brand laser cutting machine.

In doing so, he was faced with a choice between a young used or a new machine. He ended up at Laser & Bending Machines in Zwijndecht. This company of owner Nathan van der Hoeven, specializing in used laser cutting machines and press brakes, could Vink Products a Bystronic Bysprint fiber 4020 with a 6 kW laser source; only 2 years old and with only 5,000 cutting hours on the counter. “That was very interesting for us. Nathan’s way of thinking, working and guiding gave me a lot of confidence,” said Van Duijn, who was eager to go one step further than just a laser cutting machine. To use the machine most efficiently and cut a lot of material, he wanted to equip it with automation. This is what Bystronic has taken care of. Attached to the young used laser is a ByTrans Extended 4020, an intelligent solution for loading and unloading the machine.

Many benefits

The entire cutting system went into operation in mid-January and it has been a success. “This investment brings us many benefits in quality, efficiency and energy consumption,” said Van Duijn. He first mentions the leap in quality for the customer. Laser cutting produces a better cutting edge than with plasma, and there is no more plasma deposits on the sheet metal. This is important because quality requirements are also increasing in the air duct business. The channels should look good and continue to be processed without problems.

Vink itself has made efficiency gains. The four plasma tables required a lot of space, which can now be used differently because the laser takes up less space. There is also an operational cost savings. One operator now does the work at the laser instead of three at the plasma tables. Outsourcing sheet metal cutting is no longer necessary, and in addition, maintenance has become less. Not only do four plasma machines no longer need to be maintained, the contamination from the seaming machines that stood next to them is gone. And the sheet metal can now be better coded, which benefits traceability and follow-up operations.

Less waste

A nice touch is also – especially with today’s material prices – that the waste rate is down. Vink cuts about fifty item types, all in varying sizes. These are now optimally nested in Bystronic’s BySoft software. And finally, energy consumption is down. Just the elimination of the dusting units at the plasma cutting machines makes a huge difference.

All in all, Rob van Duijn speaks of a very good investment, with which Vink Products has taken a big step in the automation of the cutting process. The next step will not be long in coming: a robot for sorting out the cut parts.
