Soon after joining forces to combine their technologies for magnetic clamping, Staubli and Mag Autoblok-Tecnomagnete are introducing a new generation of quick mold change equipment for the plastic industry. Formed in October 2022, the alliance allows the two companies to combine their magnetic clamping expertise to jointly develop a new generation, high-performance range of magnetic clamping solutions for quick mold change applications for plastics injection molding.
The new system QMC 123 Premium was announced in August. The product combines Staubli’s control and precision force measurement technology, with the compact design and robustness of MAG-Autoblok Tecnomagnete magnetic platens. It provides greater levels of information with the Staubli control panel and also features a new and easier to use operator touch screen interface, enabling validation of the various safety points during mold changing operations. The IMAG-Editor software enables the clamping force for each mold to be calculated prior to loading, based upon the press on which it will be used, highlighting any potential problems ahead of production.
Staubli has been providing magnetic clamping solutions to the plastic injection molding industry for more than 20 years while Mag Autoblok–Tecnomagnete is also recognized as a leader in the field with both companies having become mainstays of a number of industries. Headquartered in Switzerland, Staubli manufactures quick connector systems for all types of fluids, gases and electrical power.
MAG-Autoblok Tecnomagnete, based in Lainate Italy close to Milan, develops magnetic work holding and clamping solutions for a range of manufacturing sectors and is widely recognized for its patented permanent electro-magnetic technology. The company’s PressTec GRIP is an advanced magnetic fixing system created in a monolithic construction from a single block of steel with the magnetic poles integral and an active part of the frame.
The exclusive GRIP effect generates magnetic force towards the machine, allowing the module to be clamped magnetically to the press. The effect is independent, rendering the pallet as a whole: machine-magnetic-mold a unique body, insensible to vibrations and to deflections. The thickness of the magnetic modules is extremely compact at only 37 mm, allowing more daylight to the machine and reducing weight, increasing the speed of molding. The GRIP effect is independent and does not affect the force that restrains the mold, thus making the entire system, magnet and mold a unique body insensitive to vibrations and deflections.
The heart of PressTec is a bi-directional permanent electromagnetic circuit, consisting of double magnetic round poles, poles arranged with N/S alternating polarity. The movement of the magnetic flux is horizontal and flattened, totally concentrated in the polar area or at the mold to be clamped. The frame is not affected by magnetism, given the total absence of magnetic dispersion.
Staubli’s Etienne Lepeule, executive president for fluid connectors, commented: “We are delighted to partner with MAG-Autoblok Tecnomagnete as our companies share strong values, with innovation in our DNA. As the company historically responsible for establishing the key principles of magnetic clamping technology, through a series of innovations and patents, their magnetic expertise and manufacturing capability will serve our partnership well.”
Carlo Munaretto, CEO MAG-Autoblok Tecnomagnete, said: “Staubli’s expertise in mold clamping control technology and software will make it possible for the new systems to deliver the highest levels of performance and safety for both existing and new customers. Furthermore, Staubli’s extensive network of facilities and local support structure, will deliver world class customer support and service.”
The new generation systems will be showcased by Staubli at the K Show for the plastics industry which takes place in Dusseldorf between the 19th and 26th of October. For more info, see www.staubli.com and www.mag-tecnomagnete.com.
