ASCONA presents world novelty PROMEX OBJECTIVE on Aluminium exhibition in Essen
Reliable and objective classification of extruded aluminium profiles
Stabilizing webs are needed for the construction of even visible surfaces when they exceed a certain size. During the production process, web collapsing occurs without fail. As the profile surface normally has a mat finish, web collapsing can hardly be detected with the naked eye. An innovative technique developed by ASCONA now provides safety through control. Its name: PROMEX OBJECTIVE.
Current practice has got its weak points. In order to be able to detect web collapsing at all, the surface of an aluminium profile sample is either treated by a polishing machine or with a coating of transparent lacquer. Identification of web collapsing is precise but depending on the incident angle of light which may distort results. Inspection is very likely to lead to subjective results in the end and opinions may vary. However, correct results are imperative because web collapsing is a substantial quality feature of visible surfaces.
PROMEX OBJECTIVE provides precise evaluation. The measuring system which was developed by ASCONA in co-operation with the Fraunhofer-Institute in Magdeburg, evaluates distortions objectively and classifies them on a 10-grades scale. It is used directly in the production area. Web collapsing is recorded within 1 to 2 seconds only. The sample with its surface to be measured is simply placed on the sensor system.
This fast and easy handling makes PROMEX OBJECTIVE an important assistant granting a reliable, objective and transparent classification of extruded profiles. Communication between the supplier and the customer is based on objective information. Default deliveries belong to the past and the costs for taking back deliveries are saved because a 100 % quality can be guaranteed.
ASCONA will present its novelty live in hall 1, booth no. 1F60 on the Aluminium exhibition in Essen.

Standard application ASCONA measuring system PROMEX
Greiner Extrusion making its mark in profiles
Extrusion technology is a rather complicated business. It’s the details that are most important to get optimum results in the end. Greiner Extrusion is a specialist in the construction and production of extrusiondies for the plastic profile production. Greiner Extrusion supplies its product range to profile manufacturers all over the world. Great emphasis is put on precision when these tools are manufactured. A measuring system made by ASCONA in Meckenbeuren/Bodensee is a means to this end. With PROMEX – the name of the system – Greiner sets new standards in the business.
Greiner Extrusion’s activities are exclusively focused on plastic profiles which is the champions league in this field. The company offers complete packages which are customized according to requirements and delivered as turnkey projects.
Tools made by Greiner Extrusion get profiles into shape. Usually, several tool sets are produced for each extrusion line. Extreme precision is required. A question of hundredths of millimeters.
„Tremendous efforts were needed but now that we use ASCONA technology, we have been able to reduce a lot of our expenditure“, says Robert Forstner (project management). According to him, Greiner Extrusion makes several test runs with each extrusion die. The company has got a number of extrusion lines which are used exclusively for test purposes. The dies are exchanged at the extruder and on the line after which a re-start is effected and the line operators produce plastic profiles with the extrusion dies in their different stages of manufacture. The profiles are then checked and manually measured by engineers. This is the moment where the measuring system PROMEX comes into the picture.
Any variations appearing between produced profiles and set dimensions were in the past evaluated with two projectors. Profile samples were placed on a light source to get an enlarged picture on a projection field. Technical drawings on parchment paper were then placed on top of this picture for comparison. If there were variations between the drawings and the picture, they were measured by hand and photographed. The big disadvantage with this method: an electronic evaluation or a resulting optimisation of the production process are not possible as these image files cannot be vectorised. Another handicap is the time needed: Measurement of each profile takes approx. 1 hour. Waiting time has to be added because the number of projectors is limited.
Times of this complicated and time-consuming procedure are now over. Instead of the projectors, PROMEX now supplies exact production results. Profile recognition of this measuring system is effected by a scanner which takes only seconds. Data is centrally stored and can be called in or edited by the 8 engineers which work in this department. „The automatic profile recognition software of PROMEX Control independently allocates set measuring values and required measuring commands to each profile, describes Robert Forstner (project management) this core feature. „This guarantees a fast and safe quality check.“ PROMEX Control software indicates variations from set values and displays them in different colours. Extrusion dies are revised step by step, then tested and re-measured until they conform precisely to the set dimensions.
But it is not the real saving in expenditure alone that is in Greiner Extrusion’s opinion the strong point of this technical innovation. Another very positive aspect is the data exchange with the customer. The integrated export function permits the direct data transfer to the customer to keep him informed any time on the actual stage of his project. The customer can thus supervise the profile’s quality. And Greiner Extrusion can in turn provide evidence on the precision of their work. PROMEX further offers more safety in production and planning to the customer as existing Greiner extrusion dies can be checked on their conditions with this measuring system. A profile scan sent by e-mail is enough to accomplish the task. Upon evaluation by PROMEX, information is gained for how long an extrusion die can presumably be used, when it should be sent in for refurbishment and whether a precise flaw analysis is recommendable. Greiner Extrusion is thus able to provide a better, faster and more efficient service. Expensive intervention by service engineers is avoided. Which pleases customers very much.
In total, Greiner Extrusion has had a very good experience with this system. There is no doubt that the system is very suitable for practical use. Even re-treat of the extrusion dies could be optimized through PROMEX. Therefore it was decided to simply offer the measuring system to customers in plant engineering as well. Greiner Extrusion thus adopts the role of an intermediate seller for ASCONA technology. „Greiner Extrusion is the worldwide synonym for the best solution in profile extrusion“, this is the vision of the company, which is now additionally underlined by this innovative measuring system.

A high-profile position for the future
iNOEX and ASCONA enter into a strategic partnership for development and sales. Aluminium producers and manufacturers of plastic profiles will in the future be able to benefit from an optimum package for quality assurance through optical measurement technology.
The two companies have started their co-operation in view of merging their product ranges for aluminium and plastic profiles and to be able to better respond to the demands arising in these markets. “As a first step we want to build a modular product design. This will make profile manufacturers profit from interesting starter solutions and the option to adapt rising quality demands to the standards of their systems.”, says Reinhard Klose, CEO and partner of iNOEX GmbH. Albert Schweser, managing director of ASCONA GmbH, adds: “In October, we will show the results of this co-operation on a profile symposium where manufacturers of aluminium and plastic profiles will be presented the new PROMEX programme.”
The long-standing experience in offering technology for quality assurance which iNOEX has gained mainly in the plastic profile market and ASCONA mainly in aluminium profiles, made both companies realise that the two production processes offer some more potential for increasing efficiency. With iNOEX being a 50 % partner in ASCONA now, synergetic effects can be fully used for research and development and the creation and realisation of new ideas.
Applications for profiles made of aluminium and plastic material may differ widely, but product quality is always clearly defined. Conformity to set dimensions and surface quality determine whether the buyer is satisfied or not and this will in the end have an influence on the producer’s own competitiveness.
Optical profile measuring systems offer an important support to competitiveness. Rapidly gained precise measuring results collected during production permit early corrective interventions. Manufacturers achieve cost reduction through reduced scrap rates and low complaints cost. The overall productiveness will go up.
