Round fine-centering system
Backlash-Free, Round Fine Centering
An even smaller, round fine-centering system is coming to the market courtesy of Agathon AG, Normalien, Solothurn, Switzerland. With a location diameter of 20 mm, it fits into small tools measuring 130 × 130 mm and can be used for plate centering of multicavity tools. This further development features space-saving fitting of the centering bush; in the newly designed Standard 7992, the bush is fixed in position by a flat head screw with built-in key guidance. The bush can be set visually and screwed in – what is more, thanks to the slight additional relief at the screw head, the bush does not need to be rotated into perfect alignment.
The compact fitting requires little installation space and has almost no recesses on the mold parting line. This offers advantages, e.g. in cleanroom production, or where the molded parts cannot be caught during ejection. If the fitting still requires too much space on the tool, the centering bush can now be installed on either side: if installed on the opposite side,the bush (without the fitting) is clamped between the plates via the flange or is secured with a circlip. Particularly when the bush is installed without the fitting (i.e. is clamped), the centering system requires little space on the periphery and so there are no recesses made on the mold parting line by the fitting.
The manufacturer’s consistency in terms of compactness of design is also evident in the length. The closed installation length of the centering unit is just 36 mm while the mounting depth of the centering pillar is 17 mm, which is the standard industry plate thickness. Despite the compact design, the centering travel is exceptionally long at 11 mm,and opens up a wide range of applications for the centering unit. A rolling centering system, by way of alternative to centering with sliding surfaces, affords a low-wearing, durable solution.
