[China Aluminum Network] ASCONA, Inc., from Mekenberg, Germany, is an expert in geometric measurement and surface inspection technology in the field of optical measurement. This system can also be used for multi-cavity extrusion where some components can be placed on each extrusion so that the profile can be viewed from different angles. This system is suitable for detecting non-permanent errors/deformations: bubble: Fibrillation scratches: gap: Crack (currently only on the outside): Use of the system: Plywood Blades Ceiling Fan Light Plywood Blades Ceiling Fan Light,ceiling lamp with fan,chandelier with fan ceiling,ceiling fan with led light JIANGMEN ESCLIGHTING TECHNOLOGY LIMITED , https://www.windfansummer.com
After many years of research and testing, the new research achievement PromexCSI aluminum surface defect online optical measurement system was finally displayed at the German aluminum industry exhibition in November 2016, and newer products were released. In January 2017, ASCONA was officially launched in the Chinese market. The field of geometric measurement of extruded profiles is a leader in the global market, both in the laboratory and in the production of optical measurement systems. The new Promex Basic/Advanced quick-start device module is a camera that works with an objective lens to ensure that measurements are completed in 2–5 seconds, regardless of the complex shape. ASCONA's Promex Expert measuring device is a high-end solution for geometric measurement. In general, the Promex Expert system meets the higher requirements for measurement accuracy in shorter measurement times. Therefore, the quick identification function can avoid waste. In addition, the Promex Expert system is very stable in the use of the extruder because it is resistant to vibration, temperature, fluctuations, or dust.
ASCONA introduced newer products at the 2016 Aluminum Industry Show. The Promex CSI system is used to test visible surfaces. The camera will directly detect any irregularities in the surface of the aluminum profiles in the extruder. Promex CSI can detect signals, bubbles, quivering scratches, holes, cracks and classify them during production. This guarantees a high output of the extruder and prevents the delivery of defective products.
In addition, inspection systems for welding lines and interior rooms were also announced at the 2016 Aluminum Industry Exhibition. When the aluminum profile is formed, the raw material in the cavity of the mold separates before being pressed into one. These areas are called welding lines. Prome's new measuring system provides an objective assessment of the welding line and sets a clear quality standard for the aluminum profile room. If a crack forms outside the profile, it is mostly due to chatter marks or cracks in the inner compartment web. Promex interior inspection system is to provide inspection solutions for aluminum faults.
The Promex Objective system enables surface rib inspection of extruded aluminum profiles, which makes Ascona's profile measurement technology even more perfect.
ASCONA's Promex measurement system guarantees objective quality assessment and continuous quality control. As a result, raw materials will be saved, scrap will be reduced to a lower level, and unqualified products will be prevented from entering the market. This ensures high productivity of aluminum extrusion.
PROMEX CSI (computer surface inspection) for aluminum profile inspection
The camera device directly observes the irregularity of the extrusion profile at the extruder site. A camera component contains a camera and a light lamp component is waterproof and needs to be cooled by compressed air. The monitoring camera will be placed in the extrusion port (in the die Between head) and cooling - either between cooling and cutting saws - or after sawing 
- Errors that happened only once - Errors that occurred only in the short term because they are easily overlooked (Persistent errors, ie Mold/Die lines can be seen immediately by the operator)
Possible errors/deformations that can be detected (see next page)
- Bumps - Bubbles - Flutter Scratches - Rifts - Cracks These are just the errors that will be detected in the early stages of development, and later will develop more different quality levels that can be defined (customer specifics)
Possible error example bump point: 
The display of our system will be installed at the control end of all extruders. On the display you can define the areas of the control that should be viewed on the monitor.
When our system recognizes an error, it will be displayed on the display or semaphore, and the display will show a picture with the error. Now the extruder operator can decide whether he wants to react to irregularities or wants to ignore it. If other errors occur at the same time, they can be processed one after the other.
When the file is stored, all errors that are not ignored are saved in the specified location for easy searching. Every time an error occurs, our system will save the distance from where the error occurred, and the picture of the error itself. Based on this, the profiles will be differentiated and the operator will decide how to deal with the problematic profiles next.
Errors will be classified according to the configuration file.
All errors will be sent to an advanced system, then the entire problematic profile can be treated centrally, or defective parts of the profile can be sawn off individually.
