Play free Round Fine Centering system for centering the mold halves – a superior alternative to the conventional guide blocks (state-of-the-art).The latest product innovation by AGATHON AG is the standardized Round Fine Centering available from stock, made from roller bearing steel – patent pending. As a world first, AGATHON has developed a standardized Round Fine Centering system of innovative design over the past months which has successfully been tested at reference customers.

The demands made on molds as regards Accuracy, use without lubricant and free from wear are high and constantly rising – especially the centering of the mold halves is subject to such criteria. By means of a preloaded play free fine centering, maximum precision may be achieved - the mold halves are closed without play, unnecessary burr formation/offset at the injection-molded part are avoided. When opening the mold, the injection-molded part is gently removed from the mold without damage.
Wear-free needed The requirement made on a low-wear (wear-free) centering can be realized using a round roller centering. Thanks to the precise axial positioning of the roller cage, almost two rows of rollers are simultaneously engaged in the preload at the centering start – this guarantees a high initial load capacity and a long cycle life without noticeable wear. The initial load capacity with two rows of rollers engaged is equivalent to that of approx. 16 rows of balls. The round centering may be used with minimum quantity lubrication. Even without lubricant, e.g. for production in clean room environments.
Quality of the parts rely on quality of the mold Due to these characteristics, the Round Fine Centering is perfectly suited for mass production and/or mold tools which must be closed with high precision. Complex technical plastic parts (e.g. thin-walled injection molding) and also clean room production – to name just a few – are leading to ever higher demands being made on the tools. Depending on the application and space available, two or more fine centering units may be used. The design engineer is free to choose the arrangement and number of centering units to be used.
