Anyone who produces one billion metal pins per year around the clock can report that production is running smoothly. The art lies in making even the most difficult steps work easily to protect workers while reducing downtime and maintenance periods. KeyTec Netherlands, in cooperation with ACE Stoßdämpfer, has shown success in this area.

As a business-to-business supplier, KeyTec implements a wide range of product solutions for the automotive, energy, and consumer goods industries, as well as for commercial customers at its headquarters in Sittard in the Netherlands. The spectrum ranges from individual parts and multi-technology products to subassemblies and assemblies. This also includes their surface treatment and assembly through metal stamping, bending, and deep drawing, as well as plastic injection molding and related technologies.
In its production facilities and subsidiaries in the Netherlands, the Czech Republic, and China, the focus is on design for manufacturing, short turnaround times, and close cooperation with selected European and Asian tool manufacturers and partners for automation equipment. This also includes the technical sales team of ACE Stoßdämpfer, which has been based in the Netherlands for more than 15 years and is responsible for the Benelux countries. The synergies with manufacturers and partners such as ACE serve all of KeyTec’s end customers in terms of time-to-market, total cost of ownership, quality, and efficiency.
This pragmatic and solution-oriented approach is used daily by KeyTec’s creative and experienced staff in all customer challenges to industrialize products and assemblies. The company is certified according to IATF 16949, ISO 9001, and ISO 14001 and convinces with future-oriented solutions, as the following application proves.
Wanted: More ease of use in metalworking
For various customers from the electronics industry, KeyTec carries out certain work steps for the production of batteries. These are equipped with special pins, of which around one billion pieces are produced per year in a three-shift operation in various designs at the headquarters in Sittard. This requires machines that convert wire both swiftly and precisely, at the same time ensuring uniform quality with high productivity. Processing is done from the coil, with straightening, cutting, and cold forming taking place in the machine. Every eight hours, once per shift, these machines are supplied with new material by the operating personnel. To do this, the upper hoods of the machine, which weigh around 45 kg, have to be opened. This is also necessary on a regular basis when the tools of the machines have to be cleaned. In the rare event of machine failures, the hoods have to provide fast access to the machines and their levers, clamping jaws, and bushing-tool systems, as well as to the cross slides and heads inside.
An important reason for the considerable weight of the hoods is that the closed machine housing is supposed to effectively insulate the work noise for occupational health and safety reasons. In addition, the integrated drives, as well as the electronics and central lubrication, should be easily accessible to the maintenance team from all sides. Among other parts, two industrial gas springs are responsible for this on each hood. Provided by ACE, these ready-to-install, maintenance-free, and sealed type GS-28-200-EE-920N components are durable and filled with pressurized nitrogen gas. With an extension force of originally 920 N per gas spring, they reliably supported the muscle strength of the operating personnel when opening and closing the hoods. From the point of view of increased ergonomics and to further relieve the burden on employees, KeyTec’s technicians asked ACE’s sales engineers in the Netherlands about other ways to improve operating comfort and to modernize the existing tooling machines in a smart way.
Found: Industrial Powerise in combination with existing gas springs
Han Titulaer from the Benelux sales team then mentioned ACE’s affiliation with Stabilus Group and presented the electromechanical drive systems called Industrial Powerise. For many years, similar components provided by Stabilus have been reliably performing their services millions of times as actuators on tailgates as well as on engine and trunk hoods in a wide variety of models from the best-known automobile manufacturers.
Adapted and designed for industrial use in recent years by the technical teams at ACE and Stabilus, these components are therefore also suitable for the 45 kg hoods on the tooling machines in Sittard — in combination with the gas springs already installed. Using their extension forces, which were reduced to 700 N per unit by reducing nitrogen via ACE’s valve technology, the team identified IPR35-V-24A-200-8-65C actuators as the most suitable components for this specific case to increase operator comfort.
Once mounted and optionally powered via a 12 or 24 V connection, these Industrial Powerise reliably enable stroke movements of 200 mm in length at spindle pitches of 8 mm per revolution at the touch of a button. In this case, lifting and lowering takes place with an additional force of 65 N per actuator in combination with the gas springs. Ralf Küppers from Technical Sales and Robin Hilke, ACE’s Product Manager for Industrial Powerise, set these exact values on site at KeyTec, whereby the electrical control system could also be precisely adapted to the machine hoods via analogue interfaces.

In general, the new actuators from ACE are available with spindle pitches between 2 and 25 mm and then take over lifting, lowering, and positioning optionally with forces between 250 and 4,000 N. With stroke ranges between 50 and 350 mm, designers can thus choose precise as well as powerful and versatile vertical and horizontal motion control. What’s more, this solution can operate as an automatic positioning system for their applications, too. Since the noise level of the drive is only 55 dB (A), Industrial Powerise also enables quiet operation. These advantages make the integration of ACE’s new drives perfect for flaps, hoods, and vertical linear adjustments.
In the application described here, it proves to be a further advantage that the combination with ACE gas springs relieves the drive, which means that the weight can be higher, the movement by hand more ergonomic, and the travel speed faster. In practice at KeyTec in Sittard, this is synonymous with easier operation, faster access to the machine’s interior, and greater satisfaction of all parties involved with the quality of work processes and the reduction of noise.

Industrial Powerise is recommended in this case as a new class of electromechanical drive systems for motion control that is convenient and powerful. These unique drives ensure safety and comfort in various other industrial applications and facilitate maintenance at the same time. This innovation is based on the IATF-certified drive of the Automotive Powerise from Stabilus, the parent company of ACE, known for its actuators for tailgates, car engine and trunk hoods, and SUVs.

In addition to the electric movement, designers and users benefit from maintenance-free use and convenient manual adjustment. In combination with Stabilus’ gas springs, Industrial Powerise offers a combination of dynamic force and load balancing in addition to a product range. The control system was developed by Stabilus especially for Powerise and is manufactured in Germany. It allows automatic control of two actuators at the same time, with a choice of three different operating modes, namely push-and-hold in typing mode, automatic single push at the touch of a button, and tip-to-run when manual movement is to be triggered.
