European Springs has acquired a new and revolutionary machine, a Bruderer BSTA 500-110B. This device will allow us to produce more than 1000 stampings per minute, which means there will be 66000 stampings just in one hour. We are very satisfied with the performance of this machine designed by Swiss engineering, and want to share its innovative systems and advantages with you.

What's the design of the BSTA 500-110B?

This stamping press device possesses a high performance combined with a brilliant mechanical precision. Other key features of the BSTA 500-110B are its modern electronics and trendsetting innovations, all of this plus the traditional Bruderer Swiss technology, widely known for its reliability. The machine has connecting rods and levels that work very well with its perfected mass counterbalancing system.

What makes it so unique?
Perhaps one of the most interesting features of this device is the hardened and ground spindles of the ram height adjustment which are mounted outside the power flow. This guarantees that the ram will have a precise setting even during the punching process.

This system doesn't generate the lateral forces that would be usually transmitted into the ram guides. Again, this prevents the deflection of the punches due to eccentric loads in the die.
All these things combined mean the BSTA 500-110B provides a safe and cost/effective stamping process that will benefit European Springs' products in a completely new way.

What are its benefits?

The machine can be controlled through big touch screens that offer a detailed overview of all the ongoing processes. It also has a memory function that allows a fast and trouble-free retooling from one die to another, saving the company both time and effort. Because it's equipped with the most common bus systems, any peripheral system can be used along with it.

The device also comes with several extra options such as hydraulic tool clamping, automatic stroke change systems and an innovative oil-lubricating system. It's also worth to notice that it is protected by Unidor sensors both in tool force measurement and in press acoustic type which will stop the press before a single cycle is completed in the event of a problem.

At European Springs we are always sure we have the latest technology in pressing to suit any project you might have. Contact us today and we'll be delighted to help.

Show young kids how two magnets interact and they’ll probably be as impressed as if you were pulling a rabbit from a top hat. Levitation is not a concept that has been accepted by science, although new technological advances might bring this closer to reality, and magnetic fields have a big role in all this. But what happens when springs and magnets meet?

How Magnetic Springs Work

They are made by two pieces: a stator and a slider. When the inner poles of the inner array align with the south poles of the outer array, the magnetic spring applies zero torque and lies in a stable position. On the other hand, when all north or south poles align together the spring is in an unstable position. A little external force can provoke these changes so magnetic springs achieve high-speed motions using just the energy created by the magnetic fields instead of the gravitational field.

Why They Are Useful

Magnetic springs provide high-speed motion using minimal energy, so they could be the perfect substitute for motors. Motors are the machines conventionally used to control speed: they convert the electrical energy into kinetic one to go forward and extract this kinetic energy when they need to stop. Higher speed implies a bigger motor, which in turn will consume more energy and cost much more.

The magnetic springs, on the other hand, simply use the energy stored in the magnetic fields so they can achieve incredibly speeds consuming very little energy when compared to a conventional motor. Besides, issues such as noise, unwanted vibrations and wear are also solved with magnetic springs because they are a silent as well as profitable technology.

Magnetic springs offer a constant force over their entire working range and they don’t need electricity at all. With magnetic technology constantly developing, magnetic springs might end up by transforming the engineering world of the future. This has already been done by machines such as the 3D printer, a device that would have been thought to be impossible a few decades ago.

Here at European Springs we know how important springs are in everyday’s life. Check out our spring catalogue and if you have a visionary project in mind contact us so we help you design your perfect spring.

You might have noticed how your seat belt keeps working at its best capacity, even after years of use and sudden stops you have to make on the road.  This is mainly possible due to the use of constant force springs in seat belts. These springs are very common and you can find them in many other items, ensuring their proper function.

Constant force springs are pre-stressed, flat strips of metal. When extended, they resist the loading force applied to them. They are used when there is the need of a spring that can withstand a constant load. These springs don’t obey Hooke’s Law, that says that the force needed to extend or compress a spring by a distance is proportional to that distance (F=kX). In these springs, the force of motion is constant, and they have barely any limit to their extension speed.

How Can They Be Used?

These springs’ durability and stress resistance make them perfect for several industry uses like gym equipment, electric motors, hair dryers, toys, and other equipment that require a constant force. In industries like aerospace and medical device manufacturing, durability and safety are one of the most important factors in spring development and building.

This is why our highly-skilled engineers are trained to choose the right materials for spring building, taking into consideration the stress, temperature, and also risk of corrosion that the material might face. Our constant force springs are commonly made from texture rolled carbon steel, or from stainless steel.

Installation Procedures

Several installation procedures are possible due to the versatility that these springs provide. Cavity mounting is a common way to fit constant force springs, as it is an inexpensive assembling process. However, despite its low costs, it has high-friction levels and diminishes the spring’s lifespan.

Spool mounting involves minimising the sliding friction by the use of a spool around the axis; the spool ensures that the consistent shape will lessen the extension, and as such it prolongs the spring’s lifespan.

Dual assembly mounts two or more constant force springs side by side, attaching them with coil strips. It doesn’t add stability due to the decreased extension length but the two springs installed together will create more force.

The modern engineering world is one of immense computing skill and seemingly impossible projects undertaken with cutting edge technology. Looking at modern engineering projects it seems hard to believe that almost all engineering can trace its roots back to a man born in 287 years BC.
We are of course talking about Archimedes, one of the most recognised names in history, but who was he?

Who was Archimedes?

Born in Syracuse, Archimedes was the son of an astronomer but other than this, little is known about the life of this incredible man. For example, it is not known if he was married or had any children; what we do know about him is the incredible amount of inventions and theories that he created during his life. Unfortunately we do know that his life was cut short by a Roman soldier who killed Archimedes during the siege of Syracuse. Who knows what else could have been achieved were he to have lived longer?

Inventions and Theories

  • Screw pump

  • Claw of Archimedes (a defensive weapon)

  • Heat Ray (utilising mirrors to focus the suns heat, creating a solar furnace)

  • Explained the principle behind leverage

As well as these and many more, it is the principle of buoyancy that Archimedes is best known for, the principle that often carries his name to this day.

Archimedes Principle

Put simply this theory dictates that the buoyant force exerted on an object when partially or wholly submerged in water is equivalent to the weight of the water displaced.
