Features of the Dyno benchtop spring load testing machine

This spring testing machine is an excellent solution for analysing and evaluating the performance and characteristics of different types of springs. It’s a benchmark of the sector in terms of accuracy, repeatability, reliability and versatility.

Indeed, Dyno can test both compression and traction springs, perfectly adapting to the different types of products on the market. To test compression springs, it has plates with customisable diameters that can be fitted with guide rods, to support long and unstable springs. On the other hand, special hooks are available for testing traction springs, to ensure that the load is applied evenly and correctly.

To ensure accurate measurements of the loads of each type of spring, the Dyno spring force measuring machine can accept up to three load cells, each capable of up to 200,000 divisions. This level of accuracy allows for precise, reliable and repeatable test results, providing high quality data for analysing and evaluating spring performance, which are of great importance for both manufacturers and users.

In conclusion, the Dyno spring testing machine is an ideal solution for customers who need to test springs with low loads, not exceeding 5 kN. With its robust construction, intuitive touch display, advanced proprietary software and compatibility with Industry 4.0 standards, this machine offers excellent precision and reliability levels, to meet the needs of industrial sectors requiring accurate and repeatable spring testing.

Spring testing software and technological features of the benchtop machine

Equipped with an intuitive touch display, this spring load testing machine provides a highly intuitive user interface and allows simple and direct interaction with the operator. EasyQs, the Easydur proprietary software developed specifically for its own spring testers, offers a wide range of functions for controlling and monitoring test parameters in real time.

Thanks to a handy Wizard, creating the test recipe becomes a quick and easy process, ensuring accurate configuration and minimising human error.

The Dyno spring testing machine is designed to be fully compatible with Industry 4.0 standards, which promote the interconnection of production systems through the use of advanced digital technologies. The adoption of the OPC-UA Protocol facilitates data exchange with other devices and control systems in the production and non-production environment, enabling seamless integration within the company.

Some examples of the fields of application of the Dyno model spring testing benchtop machine

Small springs with loads up to 500 kg are used in several sectors, and their testing is often a crucial aspect in design, R&D and maintenance activities. Some examples of sectors where Dyno is used successfully include:

  • Spring manufacturers, spring wire manufacturers: it goes without saying that a Dyno machine is a must in any spring factory workshop. Indeed, while the testing of 100% of the production is entrusted to our automated testing systems, the design of a spring and the selection of the best material are often completed on Dyno type testing machines, which are also ideal for spot checks, or for testing medium to small batch sizes.
  • Automotive and transport sector: springs with loads of up to 500 kg are used in light vehicles, such as mopeds, for suspensions and shock absorbers, and in all types of vehicles for components and systems such as clutches, brakes, seats, controls and locking devices; testing each one of these components and all these springs is essential for proper operation and absolute safety on roads and tracks.
  • Electronic and electro-technical sector: small springs are used in electronic devices such as spring switches, keyboards, connectors, micro-switches and shock-absorbing components. Inaddition to dynamic tests, aimed at analysing the behaviour of the springs when subjected to fatigue, as well as simulating entire years of use, a complete characterisation of the springs in question is vital to ensure that the production of millions of units of a single product is successful and free of defects.
  • Aerospace sector: small springs are used in aerospace applications such as locking systems, opening and closing mechanisms, control systems and vibration damping systems.
  • Medical sector: springs are crucial in medical devices such as pumps, surgical instruments, actuators, breathing support devices and prostheses of all kinds. Another domain in constant evolution, the medical sector is subject to very strict regulations and controls and, in these cases, testing springs and materials is an absolute must.
  • Fashion industry: low-load springs are used for press-studs, zips, snap fasteners and adjustment mechanisms. A self-respecting compression testing machine is not limited to testing springs: it also allows to test components and end products, thanks to customised grips. Furthermore, with a simple change of accessories, Dyno can be transformed into a system for testing the strength of zips under tension, not to mention the seams and the fabrics/threads themselves.
  • Household appliance sector: small springs are found in household appliances such as washing machines, dishwashers, vacuum cleaners, refrigerators, as well as in all home automation systems.
  • Tool and equipment sector: springs are used in pliers, spring pliers, clamps, spring screwdrivers, scissors and other hand tools.
  • Games and sports industry: small springs can be used in games, toys, sports equipment such as fitness machines and trampolines.

These are just a few examples, but the testing of small springs with loads of up to 500 kg takes place in many other sectors where the end product is required to provide an elastic force to support and control movement, absorb shocks or maintain a specific position.
