Nonnenmann expands its temperature control product range with the Magnet-Quick-Holder, offering an alternative mounting option for multi-couplings. This solution allows for quick and flexible attachment to the mould without the need for threaded holes, simplifying both installation and retrofitting.

Known in the industry as a component supplier for the fields of mould making, injection moulding, automation and tool maintenance, Nonnenmann offers users a broad product portfolio and solutions for temperature control and tubing. In order to cover all applications and customer requirements, various series of monocouplings, temperature-resistant hoses and accessory parts, as well as multicouplings, play an important role in daily customer contact.

Depending on the size of the machine, the dimensions of the mould, the number of temperature control circuits and the frequency of the set-up processes, multi-couplings are part of the standard equipment of contract injection moulders and companies with their own injection moulding department. Multicouplings enable several temperature control circuits to be coupled quickly and without confusion with just one movement. Using these, up to 12 circuits can be coupled in a single step, which corresponds to a total of 24 monocouplings for supply and return. This speed enables significantly faster set-up times and ensures higher machine utilisation in injection moulding production. Process reliability is also increased because the couplings are permanently assigned to the temperature control circuits and can no longer be connected incorrectly during the set-up process.

A multi-coupling is constructed from two sides. The machine side with the installed couplings is used to supply the temperature control medium and is located on the machine. The tool side with the connection nipples is mounted in a central location on the injection moulding tool. The individual temperature control circuits of the tool are connected from here. Generally, this multi-coupling plate is bolted to the tool. In practice, however, this can lead to problems with the space required for positioning. When designing new tools, this should be taken into account and planned for during the construction phase. However, injection moulding tools are often retrofitted for use with multi-couplings.

Since the beginning of the year, Nonnenmann has been offering users a new option for attaching the multi-coupling to the tool with the Magnet-Quick-Holder (Art. No.: FL46605), which makes assembly easier, faster and more flexible.

The magnetic quick-holder can be ordered directly from the supplier as an accessory when purchasing a new multi-coupling or as a retrofit kit.

The company offers the magnetic quick-holder suitable for the common multi-coupling series M009, M090, M109, M152 and M155. The standard mounting accessories of the multi-couplings are reused during assembly and supplemented by the magnet holders. Four magnets are used per multi-coupling, which reliably hold the coupling with tubing on the tool with a high holding force. This magnet solution can be used up to a temperature of 80°C at the contact surface on the tool.

Mounting the multicoupling on the mould using magnets, as an alternative to the conventional screw connection, gives users flexibility in positioning, as no threaded holes are required in the mould. It can be quickly and easily mounted directly on the mould without the need for any additional tools. This solution is also ideal for retrofitting moulds from a single-coupling to a multi-coupling. Contract injection moulders also benefit from this solution, as it allows the supply of the mould temperature control to be flexibly adapted to their own machine conditions. This saves time and money during assembly and maintenance of the moulds.
