Multi point locking for railways from EMKA

To prevent the deformation of the enclosure and cabinet doors during closing, EMKA makes use of a multi-point latching design. This new system ensures even more efficient operation with rod controls and several locking cams now available. They are particularly aimed at the railway industry where the benefits of multi-point latching enhance the compression function to secure up to five locking points with one movement of the hand.

A switch cabinet normally requires a locking system with multi-point latching to guarantee an adequate IP rating. This solution with rod control helps specialist cabinet manufacturers to achieve this goal – it operates around an active locking point which is actuated from the outside to open and close the cabinet. This point actuates a connecting rod within the gasketing area. The remaining locking points in the shape of metal cams are mounted on bearing bushes with shafts and are connected with the rod. When a user operates the active locking point from outside, all the other cams move synchronously with the drive cam. The length of the connection rod is variable for the user, the system can be designed flexibly and adjusted to the respective switch cabinet.

This multi-point locking system with compression function is especially suited to the railway industry as the operation ensures optimum gasket compression and thus an especially high tightness of doors and flaps. All components of this system are made of stainless steel and therefore comply with all the relevant fire protection standards.

As a consequence of our long standing investments in the dual aspects of tooling and production expertise, while seeking to manufacture ever better standard modular products, ever more efficiently, our factory facilities have become very good at responding to requests for “specials”. Over many years this has developed across many industries where custom casting, moulding or related fabrication are required.

Consequently EMKA have become expert in the casting of stainless steel, spraying of zinc and high-performance plastics as well as in the extrusion of rubber and plastic profiles. Punching, bending, turning, milling, surface coating or powder coating as well as the final assembly of the modular product program ensure a unique vertical integration. The result is that an experienced team of designers, developers and engineers is available at EMKA for the creation and manufacture of individual customer solutions – an area where the company sets standards in quality, depth of production and delivery performance.

EMKA hygiene locks for food industry equipment

Appearance and preference are crucial factors in the food industry. However, in order to produce the right product, state-of-the-art machinery and a sterile working environment are critical. And there is no reason why hygiene and modern design cannot go hand in hand, as EMKA and the renowned food machinery manufacturer Seydelmann from Aalen, Germany recently have proven. EMKA will equip eight types of Seydelmann machines with quarter-turn latches and locks.

Maschinenfabrik Seydelmann KG has been driving the development, production and sale of high-quality, high-performance cutters, mixers, grinders and ultra-fine shredders for the production of sausage and meat products for 175 years.

Since the hygiene regulations in the food industry are immensely high and new certifications are always necessary, it was essential to optimise specific machine components. The EMKA hygiene quarter-turn provided to be the optimal solution for a mix of price/performance, as the lock can be integrated into existing machines with little effort.

The quarter-turn complies with protection class IP69K. It is dustproof, even at low vacuum in the housing (<= 20mbar) and waterproof from four spray directions. The stainless steel components are robust and easy to clean, and can withstand the jet of a high-pressure cleaner, for example, to enable efficient “cleaning in place”. Seydelmann’s project manager Jochen Goos, MBA Operations Manager, and Johannes Wamsler, Design Manager, were particularly impressed by the time-saving aspect. “Thanks to the EMKA quarter-turns, we can now install and uninstall our machine linings much more quickly and easily, especially during maintenance work. We save a lot of time and can concentrate on other core tasks” says Jochen Goos.
