The laminating technology means simply covering the surface of one of the materials with adhesives and pressing the other material onto it ensuring that there is no air left, producing a duplex material. Repeating the same activities we can produce a triplex material structure. Our solvent free, winding laminating machines are operating with lukewarm glues enabling the efficient and high quality production of even small quantities and the previously used environment harming solvent-using technology can be replaced.
The side-change sleeve system based on laminating work consists of 5 cylinders out of which two are heated in order to control the temperature of the adhesive. The laminating cylinder is an in-built air-cylinder onto which rubber sleeves can be pulled on from the side of the machine with the help of special valves. The rubber sleeve`s width is less than the air-cylinder`s width and equal to the laminating width. The speed of the laminating cylinder is controlled, raised and moved by detached sevo-motors. The pressing cylinder is moved by pneumatics with central pressure control.
The thickness of the adhesive is controlled by a stageless gear, enabling the application of an adhesive thickness as less as 1 g/m2, though the optimal thickness is around 1.8-2 g/m2. This setting can be changed even during production. A coloured screen terminal is used to control the adhesive thickness, the programming of the meter counter, the cylinder heating, the saving of parameter settings and other functions. Corona treatment unit and adhesive vapour exhaust unit are optional.
The increasing competition on the market requires the usage of higher and higher quality packaging materials. These high quality materials can be produced by applying the laminating technology that enables us to merge the advantageous qualities of various materials and to produce a multi-layer material structure. Using this technology almost all requirements can be covered with top quality packaging materials. From printing technology point of view it is important to note that the print itself is enclosed between two layers enabling the material to meet more rigorous health and medical requirements in addition to the better esthetic effect. Advantages of laminator machines can not always be taken of in full shift as printed material not always needs to be laminated. After laminating, however edges need to be removed and if multiple print lines are printed on the material the reel should be slitted. This means that besides the laminator machine, a slitter-rewinder is always required. As a unique solution in Europe we equipped all of our laminating machines with a blade slitter unit with a side exhauster and this way offering two complete machines with one investment. Following a retooling and the rewinding of the material the laminating machine is converted into a slitter offering us better usage of capacity and quicker ROI.
Varga-Flexo Ltd. was founded in 1993. The Founder Endre Varga had been designing and producing flexographic printing presses for 15 years at that time. He founded the company together with his son with the vision of launching new flexographic printing presses, laminators, slitters and mounter-proofers on the international market from a Hungarian producer offering excellent value for money and high quality. Endre Varga handed over the enterprise to his son, Denes Varga in 2010, but he follows the daily work, assist by his sons decisions and trusts that the grandchildren who already participate in the life of the company, will carry on the generation change. Positive feedback and friendly relationship with our customers ensure the companys competitive position in the printing market therefore their current aim is to strengthen the relationship with existing customers and find new ones.
Varga-Flexo Ltd. aims to meet the requirements where high quality, short changeover time, cost effective operations and quick ROI, and machine operator-friendly design are all important factors. Long-term orientation has a key importance thus all our machines have been operating reliably since 1993. Responding to our Customers' trust in the company, we provide stable background and constant support that in years evolves into an alliance based on mutual confidence.
Lengyeltóti Production plant
The headquarters and the service centre are in Budapest and it is also the place where you can find the driver technology and the electronic workshops where latest developments are tested before implementation. The production lines are in the factory of Lengyeltóti which is continuously expanding in capacity and where the production technologies are always updated to meet the increasing demands of the customers. The good relationship with customers does not end after installing the machines, but begins just after that, consulting, training for operators and maintenance, 24h service hotline, spare parts ordering and continuous improvement support is provided to keep the machines on a high production level. Online remote monitoring system with free Skype phone is an accessory to the machines enabling free and immediate remote support for the machine operators in case there is any need for help or service.
Our team's aim is to react to customer needs promptly and prepare quotations within 1 hour. In order to perform at highest level, we are constantly developing our IT system and company management software.
When designing the machines of Varga-Flexo Ltd. the most important factors beyond the top quality prints are reliable operation, strong framework, the shortest possible time for reel change and retooling, cost effective operation and excellent value for money. Important factors are also the easy handling and approach and machine operator-friendly covers. New innovations are tracked and tested continuously to provide the customers with always the latest technology.
