“DEEP-DRAWING SMART LUBRICATION SYSTEM
After the supply of a first lubrication device in 2019 and a second in 2021, UK stainless-steel sink producer AGA Rangemaster recently installed its third Dietronic SAGOMA-series lubrication system for its deep drawing process. The investment has increased yield and led to a significant reduction in oil consumption, according to AGA Rangemaster.
“These considerable benefits made the justification for a second, and then a third, system very straightforward decisions. At the time, we were using a couple of lubricators supplied by another company, but we were not very satisfied with them. The technology was outdated and so we started to seriously consider a restoring project for the lubrication stations”, explained Jason Allaway, Group Manufacturing Director, AGA Rangemaster.
At Dietronic’s premises, it inspected a SAGOMA system with conveyors in operation and did some tests to evaluate the machine’s functionality. It also had more specific requirements for its particular application. “The package was complete including inlet/outlet conveyors with lateral centring unit, a feature that is very useful for the sink manufacturing process and something that we considered for our project. We saw how the spray patterns could easily be programmed for the variety of different blanks used to produce the sinks. A very smart feature of SAGOMA is the ‘teach-itself’ function of the blank shape with a quickpass through the sensor bank. After this, the operator can programme exactly where the oil is needed and the quantity to apply by application in 50mm x 50 mm sections, easily selectable from the touch-screen panel. The recipe system then stores each programme for rapid start-up after changeovers. This was what we needed”, continued Jason Allaway.
After two years, the company decide to implement a second SAGOMA system featuring an external automatic spray-head cleaning system. The device is designed to automatically clean quickly and facilitate off-line maintenance operations on the spray heads and internal manifolds. The procedure implements a full flushing, cleaning, drying and diagnostic check of each nozzle with each stage displayed on the HMI in ‘real-time’ information. The process is completed quickly with a 20-nozzle system in just over five minutes.
“Both spray heads can be removed, cleaned and returned to the machine in around 15 minutes. If you have a set of spare additional spray heads set (as in our case), you won’t have to stop your production”, outlined Allaway. “The greatest difference that we immediately noted with the first system was the significant saving in oil consumption, compared to our previous lubricators. Our oil consumption has reduced by more than 70% with the Dietronic system compared to the old lubricators. We also marked a noticeable improvement in the working environment, such as greatly decreased oil mist (thanks to the high-level extraction system with HEPA filter) and reduced oil on the floor and on the machinery”, he added.
Dietronic specialises in sheet-metal lubrication and the protection of tubes and profiles, as well as customised process automation solutions.”
