Gooseneck presses
Frequently asked questions about gooseneck presses
The term “swan-necked” describes a curved shape more or less closely resembling the neck of the bird of the same name, and has its origins in the mechanical engineering sector. This type of design is mainly used in the fields of architecture (in ironwork…), construction (in piping, fittings…), special transport (for trucks and semi-trailers…) and industrial machinery (machine tools, presses…).
In the latter sector, a large number of machines need to be specially designed to meet specific production constraints when large parts or components need to be processed. The high clearance of machine tools and gooseneck presses enables modifications, treatments or assemblies to be carried out on large-scale components.
What is a high-frequency gooseneck welding press?
A high-frequency welding press is a thermoplastic assembly machine using high-frequency technology. This involves transforming an electric current into an electromagnetic field, which agitates the molecules at the edges of the parts to be welded, creating a very regular, high-strength weld.
The gooseneck refers to the shape of the press, which has been designed to meet specific constraints in terms of the space available inside the machine, known as clearance or clearance space. This allows the passage of bulky objects, wide tarpaulins or large parts during the assembly phase, using high-frequency welding technology.
Are HF welding presses the only ones with a gooseneck?
The gooseneck is above all a shape, or to use a term more commonly employed in the design of machines, industrial equipment or mechanical parts: a specific design. Consequently, for all types of equipment created to work on large products, the gooseneck, which provides a high degree of clearance, is integrated from the very first phases of the machine’s design.
When it comes to industrial presses with goosenecks, you’ll find production equipment as diverse as :
- hydraulic presses for bending, forming or crimping,
- mechanical presses for stamping, forging or punching
- hydraulic presses for deep drawing or cutting,
- electromechanical presses for forming or gluing,
- hydropneumatic presses for high-frequency welding,
- pneumatic presses for chasing or percussion marking,
- electric presses for forming or stamping,
- hydraulic presses for straightening, punching or deburring,
- mechanical presses for cutting or chasing,
- pneumatic presses for compression,
- hydraulic forging presses,
- ….
What's the difference between a gooseneck and a deep-neck press?
There are no clearly established standards for determining which machines can be classified as gooseneck presses and which as deep gooseneck presses.
In the industrial machinery sector, a convention applied by certain manufacturers of high-frequency welding presses such as Matrelec establishes that :
- gooseneck presses have a clearance behind the electrode of 1000 millimeters or less,
- deep gooseneck presses have a clearance width behind the electrode greater than 1000 millimeters.
