Production runs - Import export

Particular Challenges: In the course of the production, endless cables are running at a considerable speed, and supervision has to be carried out nearly under real-time conditions. The size of the objects to be determined, i.e. of the flaws to be discovered, is in the range of only some hundredths of a mm. Another difficulty is the fact that surfaces with very different reflectivity and roughness are involved. In order to be able to check the cables all around, several laser scanners must be in place, mounted at different angles, thus covering the entire range of 360°. Quelltech Solution: The solution consists in a configuration of four Q6 laser scanners, mutually displaced by 90°, so the entire surface of the cables is in the field of view. On the basis of the 100% inline inspection, the position of defects can precisely be determined, without losing too much time.

Using thermoforming as an alternative to metal, foam or injection moulding often makes economical sense, especially where mid-size production runs or complex components are involved.

Compressed air blade To monitor the progress of certain processes, there is no alternative but to take frequent samples at the machine itself. This is normally possible only while the product is either moving slowly or stopped, and often results in complicated work-arounds to enable continual production (continuously running winders, etc.). The Samplecut FSC is the solution to the problem. The tried and tested sample cutter Samplecut FSC takes samples from fast running product.

Keeps web safely on track Drifting of the product web lateral to the running direction of product is unavoidable in some stages of textile finishing. The Ceremat system brings the product back on the right path. Applicationspecific variants are available.

Infrared pyrometer The Thermosense HP270 is used for non-contacting temperature measurement in driers and stenters and records the temperature of running product webs. The sensor is temperature-resistant up to 270 °C. It can therefore be mounted inside driers.

Reflexion of infrared light Automatic width measurement on a running product web. IR LEDs used in reflective mode continuously and precisely determine the product width. The sensor module only needs to be attached on one side of the product. The compact design allows it to be installed even in the tightest mounting spaces. Retrofitting is possible virtually anywhere.

The SPIROL Model PH Heat Insert Driver provides an accurate and consistent method to simultaneously install multiple Threaded Inserts or Compression Limiters at multiple elevations. Simultaneous installation dramatically increases productivity and simplifies the number of manufacturing steps to complete an assembly. Additionally, the platen head and fixture can be easily changed to accommodate quick change-over to different assemblies associated with new production runs. This machine can be used to install 12 Inserts into 1 assembly, or a fewer number of Inserts into a larger number of assemblies – as long as the total combination does not exceed 12 Inserts.

“Heat”resistant buffer pad For hot processing. Nonferrous metals, such as gold, copper or brass, get hot during processing and have a sensitive surface. Rollers and cylinders coated with secutex Heat protect bar stock during production; abrasion and run marks are reliably avoided. Operating temperature up to 140°C Apart from the positive mechanical and chemical properties, secutex Heat is an elastomer material for operating temperatures up to a maximum of 140°C. Operating temperature up to 180°C As an option, „Heat“ can be finished with an aramide fibre surface. The operating temperature thereby even increases to a maximum of 180°C.

The FireBird® Pro S Gold Edition with mechanical setting stroke adjustment. When setting a blind rivet nut size of the same length in consistent material thicknesses constant setting stroke should be used. The setting stroke corresponds to the distance the mandrel is drawn into the nose piece during the setting process and thus how far the blind rivet nut is upset. With the setting stroke adjustment this path can be set mechanically on the setting tool. Customer benefits of setting stroke adjustment: • Device control via setting stroke adjustment guarantees a constant height of the blind rivet nut after setting • Stepless setting of the setting stroke • Setting stroke adjustment is preferred above all by experienced users and for large production runs Technical data, working range and advantages are analogous to FireBird® Pro Gold Edition More details on delivery limits will be answered in a specific enquiry (details are only exemplary)!

There was a need for coming up with a new pad printing machine, the basis of which opens up new target markets for us both technologically and in terms of applications. The result: the development of the SPEED 40-2 pad printing machine. Its output: as many as 9,000 cycles/h in continuous run. The production quantity is max. 18,000/h printed parts (single color with a printed image size of Ø 37 mm). Very high true-to-register printing, precision contours and photo and line images. The SPEED is a built-in execution, suitable for any kind of clocked, linear or rotary transfer systems. Thanks to its integrable misprint device there is no stopping of the machine in the absence of a workpiece. The power costs are low in comparison to the cycle number (part output). The SPEED 40-2 is a fast shortstroke machine of a new series of pad printing machines.

Frequently, a production run starts or ends with the automatic feeding or removal of workpieces.

b.dry chains are made from corrossion-free, maintenance-free CF stainless steel with an optimized articulated link that represents a masterpiece of high precision. The secret of the b.dry range is to consign the old notions of „steel on steel“ to the past! The fact that no lubricants are needed is thanks to our b.dry bushes, which are made from a special, high-performance polymer. The capabilities of this material are absolutely unparalleled. b.dry products run completely dry, but are still more resistant to wear and corrosion, stronger and have a longer service life than comparable chains.
