Thanks to Traceability, Production Processes are Optimized

For more than 70 years, Dalmar has been distributing in Italy customized tightening, sealing, screwing, anti-vibration and fluid conduction solutions according to the needs of its customers. It guarantees a widespread and efficient after-sales service. Among the companies in its distribution catalog, we find HS-Technik: its products dedicated to the assembly sector ensure traceability, which today is a key factor for all companies.

Founded in 1949, Dalmar starts its activity in a small office in Milan, with two collaborators and a bicycle for deliveries. Today, it has about 40 employees and over 7,000 square meters of offices and warehouses, as well as 5 Business Units that design and provide customized solutions for companies all over the world. Dalmar SpA specializes in the distribution of products that meet the needs for sealing, tightening, anti-vibration, screwing and fluid conduction in the most complex industrial applications.
Dalmar, however, does not stop at distribution in itself, but also offers various services developed in agreement with the customer, in order to meet its specific needs. In addition, Dalmar is able to ensure widespread and efficient pre and post-sales technical assistance throughout the national territory. Among these, Dalmar guarantees product traceability, a factor that is becoming increasingly important within manufacturing companies. The range of HS-Technik cordless tools, distributed by Dalmar Spa, meets the need for traceability, but also for flexibility and freedom of movement.

Thanks to the traceability and control of assembly processes, the HS-T cordless solutions makes it possible to optimize production processes.

The benefits of traceability and process control in assembly

In recent years, companies have increasingly compelling needs in terms of quality and optimization of their production processes. This is due to the growing awareness of safety and that to be competitive they must ensure a quality finished product. Thus, traceability has become increasingly important and has extended to a wide range of sectors, such as the automotive, aerospace and electronics sectors, where quality and safety standards are high and the aim is to have a “zero defect” finished product. Furthermore, with the provisions of the law on liability for damage from defective products and their distribution, the risks for manufacturers increase, in the event that the products do not comply. In this direction, the VDI / VDE 2862 directive, first applied to the automotive industry, and since 2015 extended and applied to all system, machine and appliance manufacturers, establishes the minimum requirements for the use of screw systems and industrial tools; the directive also provides a risk classification linked to the extent of the possible failure.
The HS-T cordless tools distributed by Dalmar largely comply with these requirements, and are already used by major car manufacturers, representing a complete range capable of satisfying various industrial applications. The traceability and control of assembly processes, guaranteed by the electronic solutions, cordless but not only, that the Dalmar group offers for the national market, make it possible to optimize production processes and improve their quality.

The advantages of cordless tools

An important benefit of cordless tools is their flexibility of use: in addition to boasting the reliability of direct and real-time control on the production process, cordless tool offer flexibility and freedom of movement.
Using the range of HS-T cordless tools, Lean Managers and Quality Managers can have total control on every single assembly operation and promptly detect the weaknesses of the assembly process, in order to plan corrective measures for a continuous improvement of all lines.
HS-Technik’s battery-powered electronic systems, such as TorqBee, RivBee and NutBee, are an ideal solution for industrial applications where the presence of safety issues requires greater control on the assembly process. From the simple screw / rivet counting function to the most advanced functions such as torque / angle and force / stroke control, bar code reading and radio communication. The HS-T cordless tools offer high levels of control and traceability of the production process with or without a control unit, in an Industry 4.0 perspective.

RivBee offers a high control and traceability of the riveting process with or without control unit, in an Industry 4.0 perspective.

Thanks to an integrated USB interface at the tool base, 100 programs can be programmed, which can also be activated via barcode reader and stored up to 150,000 results, including curves; they can be exported to Excel for further analysis. The tool immediately checks whether the values reached at the end of the cycle fall within the parameters entered during programming and evaluates the process. The operator can see the results directly on the OLED display, in addition to receiving information on the battery status, the count of screws / rivets or the selected program. Information on the display include: OK / NOK evaluation, battery status, calculation function, torque, rotation angle and much more. In addition, the integrated bar code reader, if associated with a program saved in the tool, makes it possible to recall it and process it immediately.

Up to 20 tools connected to a single control unit

To facilitate production management and control, a control unit can be connected to the tool. The BTC makes it possible to manage up to 20 cordless tools at the same time, such as riveters, pullers and screwdrivers, and connect them to the factory network. Centralized information, which is visible remotely by anyone on any PC, tablet or smart device, guarantees that you know the status of all lines and workstations.
The connection to the production line and the integrated barcode reader strengthen safety in the most important applications in the automotive, aerospace and electronics sectors. In particular, the use of a bar code reader integrated in the tool makes it possible to track additional information, such as the serial numbers of the installed components, and therefore allows you to accurately track the eventual component to be checked, reducing costs due to the reworking of the finished product. And where it comes to the eventual recall from the market, it is possible to manage it efficiently thanks to the documentation that guarantees the assembly done.

The entire HS-T cordless range distributed by Dalmar is the ideal solution for safety critical applications. The TorqBee screwdrivers, thanks to the dynamic transducer and encoder guarantee the highest torque precision on the market: <1% in accordance with the VDI / VDE 2862 certification. Furthermore, RivBee riveters equipped with monitoring of the collection container and pressure sensor meet the requirements of the EU Directive 2006/42 / EC, which establishes that machinery and tools must be made safe to avoid endangering the user. Among the other advantages to be mentioned, let’s not forget the possibility of using the same Li-Ion 18V battery, 2.5, 5 or 7.5 Ah, and the quick charger of the HST-PR series, for all models of screwdriver, riveters and pullers.
