Precise centring is essential for the reliable operation of injection moulds. It ensures the precise alignment of mould halves and mould inserts and lays the foundation for consistently high component quality. At the same time, the quality of the centring units and locks used has a significant impact on the service life of the mould.

Meusburger offers a wide range of centring units and locks for a variety of applications. Depending on requirements, various sizes and versions are available with or without DLC coating. The portfolio has recently been expanded to include roller centring, which strategically complements the existing product range.

Meusburger manufactures most of its centring units and locks entirely at its site in Wolfurt, Austria. According to the company, end-to-end in-house production helps ensure consistently high component quality and reliable precision.

A key feature of the centring units is the high-precision symmetry of each individual centring half. This allows both complete assemblies and individual components to be replaced easily. For mould makers, the company says, this supports simpler and more flexible maintenance, improves process reliability and ensures fast component availability through efficient logistics.

The right centring unit for every application

Different mould designs and mould sizes place specific demands on centring technology. Meusburger offers a wide range of centring units and locks for this purpose — from solutions for micro moulds right through to centring units for large mould bases. The range includes both round and square designs in a wide variety of sizes. Variants are also available with or without a DLC coating. Depending on the application, different versions can also be selected to suit the machining direction. This gives customers a flexible range of options, enabling them to select the centring solution that is perfectly suited to the specific mould design.

External locks: The DLC coated surfaces minimise friction and ensure low-wear operation. An integrated collision protection system prevents damage to the mould, even if there is a lateral offset between the mould halves. A removal groove also allows for quick removal during maintenance.

Internal locks: They ensure high-precision centring and can be used for both complete moulds and mould inserts. An integrated withdrawal thread makes removal much easier and reduces the time required for maintenance and service.

Centring units and locks for mould inserts

Meusburger offers small, compact and space-saving locks for the precise alignment of mould inserts. The fine centring unit, flat E 13076 is supplied ready-to-use. One mould insert is rigidly mounted, whilst the counterpart is floating. This allows the inserts to be positioned precisely in relation to one another. The E 13070 variant offers additional flexibility, as it can be individually cut to length or drilled.

Fine centring unit with exceptional centring performance

With the fine centring unit with roller cage E 1355, Meusburger is expanding its range to include a high-performance solution for demanding applications. Roller centring ensures precisely defined centring without play thanks to optimally designed preload. The unit is characterised by its high wear resistance and long service life. Particularly when dealing with delicate items, tight tolerances and a high number of shots, the new roller centring unit really shows its strengths. Furthermore, it can be positioned flexibly within the mould, giving designers greater freedom in the design of the mould.
